[0026] Figure 2 It is a schematic structural diagram of a system for identifying feed ratio based on the calf weighing process provided by an embodiment of the present application. Detailed Embodiment

[0027] By providing a method and system for identifying feed ratio based on the calf weighing process, the embodiment of the present application solves the problem that the relevance between feed ratio identification update and calf weight in the prior art is insufficient. By obtaining the weight of the calf, it is judged whether the first feed ratio adjustment is performed according to the feed ratio adjustment index obtained from the acquired feeding data. Then, the feed adjustment effect index is obtained according to the feeding change data after the feed ratio adjustment. If the feed adjustment effect index is not greater than the preset adjustment effect threshold, the second feed ratio adjustment is performed. Finally, if the feed adjustment effect index is greater than the preset adjustment effect threshold, it is judged whether to prompt the preset personnel to optimize the calf feeding management according to the feed ratio timeliness index obtained from the feeding time data, realizing the improvement of the timeliness of calf feed ratio update.

[0028] The technical solution in the embodiment of the present application for solving the problem that the relevance between feed ratio identification update and calf weight is insufficient is generally as follows:

[0029] The first feed ratio adjustment is performed according to the feed ratio adjustment index obtained from the feeding data. Then, if the feed adjustment effect index obtained from the feeding change data is not greater than the preset adjustment effect threshold, the second feed ratio adjustment is performed. Finally, the feed ratio timeliness index is obtained according to the feeding time data, and it is judged whether to prompt the preset personnel to optimize the calf feeding management based on the feed ratio timeliness index, achieving the effect of improving the timeliness of calf feed ratio update.

[0030] To better understand the above technical solution, the above technical solution will be described in detail below in combination with the accompanying drawings of the specification and specific embodiments.

[0031] Such as Figure 1As shown in the figure, it is a flowchart of a feed ratio identification method based on the calf weighing process provided by an embodiment of the present application. The method includes the following steps: S1, First feed ratio judgment: Determine whether to perform the first feed ratio adjustment by obtaining the weight of the calf in real time through a dynamic weighing platform; S2, First feed ratio adjustment: If the first feed ratio adjustment is to be performed, obtain the feed ratio adjustment index based on the obtained feeding data, and perform the first feed ratio adjustment according to the feed ratio adjustment index. The feed ratio adjustment index is used to quantitatively evaluate the degree of demand for feed adjustment; S3, Second feed ratio adjustment: Obtain the feed adjustment effect index based on the obtained feeding change data of the calf after the feed ratio adjustment. If the feed adjustment effect index is not greater than the preset adjustment effect threshold, perform the second feed ratio adjustment. The feed adjustment effect index is used to quantitatively evaluate the adjustment effect of the feed ratio; S4, Calf feeding management optimization: If the feed adjustment effect index is greater than the preset adjustment effect threshold, obtain the feed ratio timeliness index by evaluating based on the obtained feeding time data of the calf. Determine whether to prompt the preset personnel to optimize the calf feeding management based on the feed ratio timeliness index. The feed ratio timeliness index is used to quantitatively evaluate the timeliness of feed update.

[0032] It should be added that the feeding data includes the average daily age increment, feed intake, water intake, and feed conversion rate; the feeding change data includes the number of diarrhea times, average daily age increment, feed intake, and feed conversion rate; the feeding time data includes the number of feeding times, feed ratio update frequency, feeding amount, and feed intake; all the analyses involved in this example are for a single calf.

[0033] The average daily age increment is obtained by weighing the calf with a mobile calf weighing device to obtain the weight difference between two adjacent days and performing a ratio operation with the calf's age; the age is obtained by calculating the difference between the date of birth and the current date; the feed intake represents the total amount of feed ingested by the calf within a preset time period, which is represented by the difference between the feeding amount and the remaining feed amount. The remaining feed amount is obtained by weighing the collected remaining feed with an electronic scale; the water intake represents the total amount of water ingested by the calf within a preset time period, which is represented by the difference between the supplied water amount and the remaining water amount. The supplied water amount is represented by the feeding amount set by the system, and the remaining water amount is obtained by weighing the collected remaining water with an electronic scale; the feed conversion rate is obtained by performing a ratio operation on the feed intake of the calf and the average daily age increment, representing the amount of feed required for unit body weight gain. When the average daily age increment is 0, the feed conversion rate is recorded as 0.

[0034] The number of diarrhea times represents the number of diarrhea times of the calf within a preset time period, which is obtained by a preset person counting the number of diarrhea occurrences of the calf within a preset time period; the number of feeding times represents the number of times the preset person feeds the feed within a preset time period; the feed ratio update frequency represents the number of times the feed ratio is changed or the feed ingredients are adjusted within a preset time period recorded by the system; the feeding amount represents the total amount of feed fed within a preset time period set by the system.

[0035] In this embodiment, the preset time period is set according to the feeding cycle. For example, during the lactation period, the preset time period can be set to one day; the preset adjustment effect threshold is represented by the average value of the feed adjustment effect indexes that are qualified in the historical time period. The feed adjustment effect may be affected by various factors, such as raw material quality, processing process, environmental conditions, etc., which may cause the feed adjustment effect to fluctuate within a certain range. By selecting the maximum value as the threshold, the influence of this fluctuation on the evaluation of the feed adjustment effect can be reduced to a certain extent, so as to meet the growth needs of calves and optimize the feed utilization efficiency. By monitoring the weight, feeding behavior and feed ratio data of calves in real time, the feed ratio is dynamically adjusted and the adjustment effect is quantified, so as to optimize the feeding management, improve the growth efficiency of calves, and improve the timeliness of the update of the calf feed ratio.

[0036] In the fine feeding management of large-scale ranches, the corresponding milk volume and feeding frequency are determined according to factors such as the weight and age of calves to achieve precise feeding; the output of milk liquid is controlled by a stainless steel sanitary pump to ensure that calves can obtain an accurate milk volume supply; in terms of improving the survival rate and growth quality of calves, precise feeding can ensure that calves obtain sufficient and appropriate nutrition to meet their growth and development needs.

[0037] Furthermore, the feed ratio adjustment index is obtained by processing the average daily age increment deviation, water intake deviation, feed intake deviation and feed conversion rate deviation: the average daily age increment deviation (i.e., ) is obtained by performing a ratio operation on the average daily age increment and the difference between the average daily age increment and the average daily age increment of the previous day; the water intake deviation (i.e., ) is obtained according to the relative relationship between the water intake of calves and the preset water intake in the database. Specifically, the water intake deviation is obtained by performing a ratio operation on the difference between the water intake and the preset water intake in the database and the preset water intake; the feed intake deviation (i.e., ) is obtained according to the relative relationship between the feed intake of calves and the preset feed intake. Specifically, the feed intake deviation is obtained by performing a ratio operation on the feed intake and the preset feed intake in the database; the feed conversion rate deviation (i.e., ) is obtained according to the relative relationship between the feed conversion rate of calves and the preset feed conversion rate in the database. Specifically, the feed conversion rate deviation is obtained by performing a ratio operation on the feed conversion rate of calves and the preset feed conversion rate in the database.

[0038] It should be understood that the specific method for obtaining the feed ratio adjustment index is:

[0039]

[0040] In the formula, n represents the number of calves, n = 1, 2,..., N, and N represents the total number of calves, TZn represents the feed ratio adjustment index of the nth calf, represents the average daily age increment of the nth calf, represents the average daily age increment of the previous day of the nth calf, CSL n represents the feed intake of the nth calf, SZH n represents the feed conversion rate of the nth calf, YSL n represents the water intake of the nth calf. RZL0 represents the preset average daily age increment, YSL0 represents the preset water intake, SZH0 represents the preset feed conversion rate, and CSL0 represents the preset feed intake.

[0041] In this embodiment, the aforementioned database is a database for storing various setting data established before the design of a feed ratio identification method based on the calf weighing process provided by the embodiment of the present application. The database includes but is not limited to the preset average daily age increment, preset water intake, preset feed conversion rate, etc. The various values therein are directly set by technicians. For example, the preset average daily age increment is set according to the growth cycle of the calf. Generally speaking, the average daily weight gain of the calf is between 0.6 - 1.0 kg. The preset water intake is set according to the growth cycle of the calf. For example, the water intake of a 1-month-old calf may be between 3.87 - 6 kg / day. The preset feed conversion rate is set according to the feed quality. Generally speaking, the feed conversion rate of the calf may be between 2.5 - 3.5. The preset feed intake is set according to the feed intake in the growth cycle of the calf. For example, the feed intake of a 1-month-old calf may be about 4 kg.

[0042] In the specific method for obtaining the feed ratio adjustment index, the average daily age increment is less than the average daily age increment of the previous day. If the average daily age increment is not less than the average daily age increment of the previous day, continue to monitor the calf.

[0043] In this algorithm, the feed ratio adjustment index is obtained by processing multiple independent variables (average daily age increment, water intake, feed conversion rate, feed intake). There is an interaction relationship between these independent variables. The average daily age increment of the calf will remain stable or gradually increase. If the average daily age increment is less than the average daily age increment of the previous day, it indicates that the feed conversion rate and feed intake are lower, and the feed ratio needs to be adjusted to improve the feed conversion rate. For example, in the fattening stage, increase the proportion of protein and fat to meet the needs of the calf for rapid growth and fat deposition. The average daily age increment of the calf is usually positively correlated with its feed intake. The larger the feed intake, the more nutrients the calf can obtain, which helps to increase its weight. The larger the water intake of the calf, the more conducive it is to the digestion and absorption of feed. In summary, the feed ratio adjustment index is positively correlated with the deviation of the average daily age increment and the deviation of the water intake, and negatively correlated with the feed intake and the feed conversion rate.

[0044] Through the above steps, the demand degree of feed adjustment is quantitatively evaluated, and then the optimization of feed ratio and the improvement of feed utilization efficiency are realized.

[0045] Further, the specific process of obtaining the weight of the calf in real time through the dynamic weighing platform to determine whether to make the first feed ratio adjustment is as follows: when the age of the calf is less than the first preset age, it is judged whether the weight of the calf is within the first preset weight range: if the weight of the calf is within the first preset weight range, that is, not less than the first preset minimum weight and not greater than the first preset maximum weight, then the first feed ratio adjustment is not made; if the weight of the calf is less than the first preset minimum weight, the prepared first milk powder is used, otherwise the prepared second milk powder is used; when the age of the calf is less than the second preset age, it is judged whether the weight of the calf is within the second preset weight range: if the weight of the calf is within the second preset weight range, that is, not less than the second preset minimum weight and not greater than the second preset maximum weight, then the first feed ratio adjustment is not made; if the weight of the calf is less than the second preset minimum weight, the protein content and energy density in the feed are increased according to the feed ratio adjustment index, otherwise the protein content and energy density in the feed are decreased according to the feed ratio adjustment index.

[0046] In this embodiment, the first preset weight range refers to the range between the first preset minimum weight and the first preset maximum weight; the second preset weight range refers to the range between the second preset minimum weight and the second preset maximum weight; the first preset age, the second preset age, the first preset weight range and the second preset weight range are set according to the type and growth cycle of the calf. For example, the first preset age is set to 21 days old, the first preset minimum weight is set to 30 kg, the first preset maximum weight is set to 50 kg, then the first preset weight range is set to 30 kg to 50 kg; the second preset age is set to 90 days old, the second preset minimum weight is set to 50 kg, the second preset maximum weight is set to 100 kg, then the second preset weight range is set to 50 kg to 100 kg.

[0047] Using the prepared first milk powder: The first milk powder is used to provide additional nutritional support and usually contains 15 - 25% fat and 18 - 24% protein; using the prepared second milk powder: The second milk powder is used to control the energy intake of the calf and usually contains 6 - 10% fat and 15 - 18% protein.

[0048] Adjust the protein content and energy density in the feed according to the feed ratio adjustment index. The increase in protein and energy density can be achieved by adding high-quality protein sources (such as soybean meal, fish meal, whey powder, etc.) and high-energy raw materials (such as corn flour, cereal flakes, etc.). Dairy product substitutes (whey powder) can provide additional lactose and protein to help accelerate growth. For example, when the protein content is 15% and the feed ratio adjustment index is 2.25, the increased protein content is 33.75% (15% * 2.25).

[0049] Reduce the protein content and energy density in the feed according to the feed ratio adjustment index. Decrease the proportion of high-energy components (such as corn, cereal flakes, etc.) in the feed and replace them with raw materials with lower energy density (such as hay, grass powder, etc.). Add forage, soybean meal or bran to increase the fiber content and reduce the total energy intake.

[0050] Through the judgment of the dynamic weighing platform and preset conditions, the real-time monitoring and precise feeding of the calf weight are realized, avoiding growth problems caused by overfeeding or nutritional deficiencies, thus realizing the optimization of the feed ratio and precise feeding, and further improving the feed utilization rate and the growth efficiency of the calf.

[0051] Furthermore, the feed adjustment effect index is obtained by processing the milk stain residue influence factor, daily average weight gain adjustment coefficient, feed conversion rate adjustment coefficient, feed intake adjustment coefficient and diarrhea frequency adjustment coefficient; the daily average weight gain adjustment coefficient (i.e., ) is obtained according to the relative relationship between the daily average weight gain of the calf and the daily average weight gain after feed ratio adjustment; the feed conversion rate adjustment coefficient (i.e., ) is obtained according to the relative relationship between the feed conversion rate of the calf and the feed conversion rate after feed ratio adjustment; the feed intake adjustment coefficient (i.e., ) is obtained according to the relative relationship between the feed intake of the calf and the feed intake after feed ratio adjustment; the diarrhea frequency adjustment coefficient (i.e., ) is obtained according to the relative relationship between the diarrhea frequency of the calf and the diarrhea frequency after feed ratio adjustment.

[0052] It should be understood that the specific method for obtaining the feed adjustment effect index is as follows:

[0053]

[0054] In the formula, n represents the calf number, n = 1, 2,..., N, N represents the total number of calves, TX n represents the feed adjustment effect index of the nth calf, RZL n ′ represents the daily average weight gain after feed ratio adjustment of the nth calf, RZL n represents the daily average weight gain of the nth calf, CSLn ′ Indicates the feed intake of the nth calf after the feed ratio is adjusted, CSL n represents the feed intake of the nth calf, SZH n ′ It represents the feed conversion rate of the nth calf after the feed ratio is adjusted, SZH n represents the feed conversion rate of the nth calf, FXL n represents the number of diarrhea of ​​the nth calf, FXL0 represents the preset number of diarrhea, and β represents the influencing factor of milk stain residue.

[0055] In this embodiment, the preset number of diarrhea times is represented by the average number of diarrhea times of calves in healthy condition within a historical time period; the average age increment per day, feed intake, and feed conversion rate represent the data obtained before feed adjustment; the average age increment per day after feed ratio adjustment, feed intake after feed ratio adjustment, feed conversion rate after feed ratio adjustment, and the number of diarrhea times represent the data obtained after feed adjustment, which is equivalent to the data obtained the day after feed adjustment.

[0056] The milk residue influencing factor is obtained from the database, which indicates the influence of the milk residue on the feed adjustment effect index. For example, a mapping set of milk residue and its corresponding influencing factor is constructed based on the relationship between the historical milk residue and the feeding change data (such as feed intake and diarrhea frequency), and the real-time milk residue is input into the mapping set to obtain the corresponding milk residue influencing factor; the milk residue is obtained by the weight difference before and after the stainless steel sanitary pump is cleaned.

[0057] The feed adjustment effect index in this algorithm involves processing multiple independent variables (diarrhea rate, average daily increment, feed intake, and feed conversion rate), and there is a mutual influence relationship between these independent variables; a higher diarrhea rate may lead to poor nutrient absorption, affecting the average daily increment and feed conversion rate; a decrease in the average daily increment may be related to digestion problems or an unbalanced feed ratio, which in turn affects the feed conversion rate; a decrease in feed intake may lead to malnutrition or growth retardation, directly affecting the average daily increment and feed conversion rate; a lower feed conversion rate may reflect an unreasonable feed formula or health problems, leading to a decrease in the average daily increment and an increase in the diarrhea rate; in summary, the feed adjustment effect index is negatively correlated with the diarrhea rate; the feed adjustment effect index is positively correlated with the average daily increment adjustment coefficient, the feed conversion rate adjustment coefficient, and the feed intake adjustment coefficient.

[0058] To simplify the analysis, we define Among them, RZ n It represents the average incremental adjustment coefficient of the nth calf's age, defined as Among them, SZ n represents the feed conversion rate adjustment factor of the nth calf, defined as Among them, CSn Let \(a_n\) represent the feed intake adjustment coefficient of the \(n\)th calf. The specific method for obtaining the feed adjustment effect index after simplification is as follows: Taking the milk stain residue impact factor as 1 and the preset number of diarrhea times as 5, the change statistical table of the feed adjustment effect index is shown in Table 1:

[0059] Table 1 Change Statistical Table of Feed Adjustment Effect Index

[0060]

[0061] From the data of the first and second groups in the table, it can be seen that when the average daily age increment adjustment coefficient increases, the feed adjustment effect index increases accordingly; from the data of the second and third groups, it can be seen that when the feed conversion rate adjustment coefficient increases, the feed adjustment effect index increases accordingly; from the data of the third and fourth groups, it can be seen that when the feed intake adjustment coefficient increases, the feed adjustment effect index increases accordingly; from the data of the fourth and fifth groups, it can be seen that when the number of diarrhea times increases, the feed adjustment effect index decreases accordingly.

[0062] Through the above steps, the adjustment effect of the feed ratio is quantitatively evaluated, and further optimization of the feed ratio is realized.

[0063] Furthermore, the specific process of the second feed ratio adjustment is as follows: Determine whether the feed adjustment effect index is less than the preset adjustment effect threshold: If the feed adjustment effect index is less than the preset adjustment effect threshold, then perform the second feed ratio adjustment; if the feed adjustment effect index is not less than the preset adjustment effect threshold, then do not perform the second feed ratio adjustment; The second feed ratio adjustment includes adjusting the feeding amount of calves, adding feed additives, and the cleaning frequency of the stainless steel sanitary pump.

[0064] In this embodiment, the preset adjustment effect threshold is represented by the average value of the qualified feed adjustment effect indexes within the historical time period.

[0065] Adjust the feeding amount of calves: If the average daily age increment is lower than the preset average daily age increment, then increase the feeding amount through the stainless steel sanitary pump. For example, the first feeding amount is 2 kg, and it increases to 2.5 kg after the second adjustment to meet the nutritional needs of the calves, otherwise reduce the feeding amount; The specific feeding amount is set according to the growth cycle and weight of the calves. For example, within 3 - 5 days after birth, the feeding amount is 10% - 12% of the weight, and the temperature is maintained at 38 - 40 °C.

[0066] Add feed additives: In order to improve the nutritional value of the feed, it may be necessary to add specific feed additives, such as vitamins, minerals, or enzymes, etc., to improve the absorption rate and growth rate of calves. For example, add vitamins A and D to ensure better support for the immune system of calves.

[0067] Increase the cleaning frequency of the stainless - steel sanitary pump: The lower the cleaning frequency of the stainless - steel sanitary pump, the easier it may be for milk stains to remain in the pump, affecting the quality of the feed, and thus affecting the appetite of calves and the feed absorption effect. For example, increase the cleaning frequency from once a week to once every two days to ensure good hygiene of the stainless - steel sanitary pump and reduce the contamination of bacteria and milk stains.

[0068] Through the above steps, the conversion efficiency of the feed is improved, ensuring the optimization of the feeding effect.

[0069] Furthermore, the feed ratio timeliness index is obtained by processing environmental factors, feeding accuracy coefficient, and feed management coefficient; the feeding accuracy coefficient (i.e., ) is obtained by processing the feeding amount, milk stain residue amount, and feed intake of calves after adjusting the feed ratio; the feed management coefficient (i.e., ) is obtained by processing the feed ratio update frequency of calves, feeding times, preset feed ratio update frequency in the database, and preset feeding times; the environmental factor represents the influence degree of environmental data on the feed ratio timeliness index.

[0070] It should be added that the specific method for obtaining the feed ratio timeliness index is:

[0071]

[0072] In the formula, n represents the calf number, n = 1, 2,..., N, N represents the total number of calves, SG n represents the feed ratio timeliness index of the nth calf, TX n represents the feed adjustment effect index of the nth calf, TWL n ′ represents the feeding amount of the nth calf after adjusting the feed ratio, NCL n ′ represents the milk stain residue amount of the nth calf after adjusting the feed ratio, TWP n represents the feeding times of the nth calf, CSL n ′ represents the feed intake of the nth calf after adjusting the feed ratio, SZH n ′ represents the feed conversion rate of the nth calf after adjusting the feed ratio, SGX represents the feed ratio update frequency, TWP0 represents the preset feeding times, SGX0 represents the preset feed ratio update frequency, TX0 represents the preset adjustment effect threshold, and α represents the environmental factor.

[0073] In this embodiment, the difference between the feeding amount after the feed ratio is adjusted and the milk stain residue amount is not zero; the preset feeding frequency is represented by the average value of the feeding frequencies within the historical time period; the preset feed ratio update frequency is represented by the average value of the feed ratio update frequencies within the historical time period; the milk stain residue amount is obtained through the weight difference before and after cleaning with a stainless steel sanitary pump; the feeding amount and the milk stain residue amount are data obtained on the day after the feed is adjusted.

[0074] The environmental factor is obtained from the database and represents the influence degree of environmental data on the feed ratio timeliness index. For example, a mapping set of environmental data and its corresponding influence factors is constructed based on the relationship between historical environmental data (temperature, humidity, ammonia concentration) and feeding time data (such as feeding frequency, feed ratio update frequency), and the real-time environmental data is input into the mapping set to obtain the corresponding environmental factor; the temperature is obtained through a thermometer; the humidity is obtained through a hygrometer; the ammonia concentration is obtained through an ammonia detector.

[0075] In this algorithm, the feed ratio timeliness index is obtained by processing multiple independent variables (feeding frequency, feed ratio update frequency, feeding amount, feed intake), and there are mutual influence relationships among these independent variables; the feeding frequency directly affects the number of daily meals and the degree of satiety of the calf. The larger the feeding frequency, the more likely it is to increase the feed intake of the calf, especially in the young calf stage; the higher the feeding frequency means that fresh feed is supplied more frequently, which may lead to a larger feed intake; the higher the feed ratio update frequency means that the feed ratio is adjusted more timely according to the growth and health status of the calf to ensure that its nutritional needs are met, indirectly affecting a higher feed intake of the calf; the larger the feeding amount directly determines the energy and nutrient intake of the calf per feeding, and thus leads to a larger feed intake; in summary, the closer the feeding accuracy coefficient and the feed management coefficient are to 1, the larger the feed ratio timeliness index.

[0076] To simplify the analysis, it is defined that where C n represents the accuracy coefficient of the nth calf, and it is defined that where T n represents the management coefficient of the nth calf. Then the specific method for obtaining the feed ratio timeliness index after simplification is SG n =α*exp[sech(C n )+sech(T n )], TX n ≥TX0. Taking the environmental factor as 1, the preset adjustment effect threshold as 1, the feed adjustment effect index as 2, and the total number of calves as 1 as an example, the change statistical table of the feed ratio timeliness index is shown in Table 2:

[0077] Table 2 Change Statistical Table of Feed Ratio Timeliness Index

[0078]

[0079] From the data of the first and second groups in the table, it can be seen that the larger the accuracy coefficient, the less the feeding accuracy coefficient is close to 1, and the timeliness index of feed ratio decreases accordingly. The larger the management coefficient, the less the feed management coefficient is close to 1, and the timeliness index of feed ratio decreases accordingly.

[0080] Through the above steps, the timeliness of feed update is quantitatively evaluated, and further the timeliness of calf feed ratio update is improved.

[0081] Furthermore, the specific process of determining whether to prompt the preset personnel to optimize calf feeding management based on the timeliness index of feed ratio is as follows: Determine whether the timeliness index of feed ratio is less than the preset feed update threshold in the database: If the timeliness index of feed ratio is less than the preset feed update threshold in the database, then prompt the preset personnel to optimize calf feeding management; If the timeliness index of feed ratio is not less than the preset feed update threshold in the database, then give feedback to the preset personnel; Calf feeding management optimization includes the first feeding management optimization and the second feeding management optimization; The first feeding management optimization includes setting the feeding frequency according to the calf's age and setting the feeding amount and the feed ratio update frequency according to the calf's weight and growth stage; The second feeding management optimization includes prompting the preset personnel to conduct health checks on the calves and optimize the feeding environment.

[0082] In this embodiment, the preset feed update threshold is represented by the average value of the qualified timeliness indexes of feed ratio within the historical time period.

[0083] Set the feeding frequency according to the calf's age. For example, for newborn calves, the first colostrum feeding is carried out within 1 hour after birth, and then the feeding frequency is gradually increased according to the calf's needs and digestive ability. During the lactation period, usually about 3 feedings are carried out every day;

[0084] Set the feeding amount and the feed ratio update frequency according to the calf's weight and growth stage. For example, during the lactation period, the daily milk feeding amount should be controlled at about 10% of the calf's weight.

[0085] Prompt the preset personnel (such as veterinarians or breeders) to regularly conduct health checks on the calves, including checks on aspects such as body temperature, respiration, and digestion, and promptly discover and handle diseases; Prompt the preset personnel to optimize the feeding environment of the calves, including keeping the cowshed clean, dry, ventilated, disinfecting regularly, and providing appropriate warming measures.

The feed ratio adjustment index is used to quantitatively evaluate the demand degree of feed adjustment; the second feed ratio adjustment module is used to obtain a feed adjustment effect index according to the obtained feeding change data of the calf after the feed ratio adjustment. If the feed adjustment effect index is not greater than a preset adjustment effect threshold, the second feed ratio adjustment is performed. The feed adjustment effect index is used to quantitatively evaluate the adjustment effect of the feed ratio; the calf feeding management optimization module is used to, if the feed adjustment effect index is greater than the preset adjustment effect threshold, evaluate according to the obtained feeding time data of the calf raising to obtain a feed ratio timeliness index, and judge whether to prompt a preset person to optimize the calf feeding management based on the feed ratio timeliness index. The feed ratio timeliness index is used to quantitatively evaluate the timeliness of feed update.

[0087] In this embodiment, it is calculated through the feeding data (such as feeding amount, feeding frequency, etc.) of the calf, which reflects the gap between the current feed ratio and the actual needs of the calf; it is calculated through the feeding change data (such as weight change, health status, etc.) of the calf after the feed ratio adjustment, and is used to judge whether the adjusted feed ratio is effective; it is calculated through the feeding time data (such as the frequency of feed replacement, time interval, etc.) of the calf raising, which reflects the speed and efficiency of feed ratio update; thus, the feeding management of the calf is optimized, and further, the timeliness of calf feed ratio update is improved.

[0088] In summary, in the embodiment of the present application, the first feed ratio adjustment is performed through the feed ratio adjustment index obtained from the feeding data. Then, if the feed adjustment effect index obtained from the feeding change data is not greater than the preset adjustment effect threshold, the second feed ratio adjustment is performed. Finally, the feed ratio timeliness index is obtained according to the feeding time data, and it is judged whether to prompt a preset person to optimize the calf feeding management based on the feed ratio timeliness index. Thus, the feeding management is optimized, and further, the timeliness of calf feed ratio update is improved, effectively solving the problem that the relevance between feed ratio identification update and calf weight in the prior art is insufficient.
