[0029] The technical solution of the present invention is described in detail with specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0030] Figure 1 A flow chart of a method for nutritional management of Tibetan chickens in high altitude areas according to an embodiment of the present invention is exemplarily shown, and the method comprises:

[0031] Step S101, obtaining environmental information of the breeding area, wherein the environmental information includes: altitude, soil information and water source information;

[0032] Step S102, determining basic feed according to the environmental information;

[0033] Step S103, in the i-th feeding cycle, feeding the Tibetan chicken according to the feeding feed of the i-th feeding cycle, when i=1, feeding the Tibetan chicken with the basic feed;

[0034] Step S104, obtaining growth data and feed consumption data of the Tibetan chicken in the i-th feeding cycle, wherein the growth data includes: weight data and fat data;

[0035] Step S105, determining whether it is necessary to adjust the feeding feed in the i-th feeding cycle according to the growth data and the consumption data;

[0036] Step S106, when it is determined that the feeding feed of the i-th feeding cycle needs to be adjusted, determining the feeding feed of the i+1-th feeding cycle according to the growth data and the consumption data;

[0037] Step S107, in the (i+1)th feeding cycle, feeding the Tibetan chicken according to the feeding feed of the (i+1)th feeding cycle.

[0038] According to the nutritional management method for Tibetan chickens in high-altitude areas, according to the embodiment of the present invention, the basic feed suitable for feeding Tibetan chickens can be determined based on the environmental information of the breeding area, the weight data and fat data of the Tibetan chickens can be accurately collected during the growth of the Tibetan chickens, and according to the weight data, fat data and consumption status of the Tibetan chickens, it can be judged whether the feeding feed needs to be adjusted, thereby improving the growth rate and quality of the Tibetan chickens.

[0039] According to an embodiment of the present invention, in step S101, environmental information of the breeding area is obtained, wherein the environmental information includes: altitude, soil information and water source information.

[0040] For example, the altitude of the breeding area is detected by GPS equipment, water samples are collected from the upstream, midstream and downstream of the water source in the breeding area, and the collected water samples are tested using a water quality analyzer to obtain water source information. Soil samples are collected from different locations in the breeding area (such as around the breeding house, feed storage area and manure storage area), and the collected soil samples are tested using a soil analyzer to obtain soil information.

[0041] According to an embodiment of the present invention, in step S102, basic feed is determined according to the environmental information.

[0042] According to one embodiment of the present invention, step S102 includes:

[0043] Determine the use results of high-energy feed and the addition results of oil feed according to the altitude;

[0044] Determining the soil deficiencies based on the soil information;

[0045] Determining the lack of substances in the water source according to the water source information;

[0046] The basic feed is determined according to the results of using the high-energy feed, the results of adding the oil feed, the deficient substances in the soil and the deficient substances in the water source.

[0047] For example, according to the altitude of the breeding area, determine whether the breeding area is a high-altitude area. The temperature in high-altitude areas is low, and Tibetan chickens need more energy to maintain body temperature and carry out daily activities. Therefore, the result of using high-energy feed is "confirmed to use" (using feed with higher energy content, such as corn and barley). At the same time, oil feed (such as sunflower oil, corn oil and fish oil) can be added to increase energy supply. The result of adding oil feed is "confirmed to add". The soil and water sources in high-altitude areas may lack certain minerals and vitamins, which need to be supplemented in the feed. According to the soil information and water source information, determine the substances lacking in the soil and water sources, that is, soil Soil deficiencies and water source deficiencies; obtain commonly used Tibetan chicken feed (feed frequently used in historical feeding cycles); when the high-energy feed usage result is "confirmed to use", replace part of the energy feed in the commonly used Tibetan chicken feed with corn and barley (where corn accounts for 45% of the total basic feed and barley accounts for 15% of the total basic feed); when the oil feed addition result is "confirmed to add", add oil feed to the commonly used Tibetan chicken feed, and the added amount is 5% of the total basic feed; according to the soil deficiencies and water source deficiencies, add corresponding minerals and vitamin supplements to the commonly used Tibetan chicken feed, and the added amount is 1% of the total basic feed.

[0048] According to one embodiment of the present invention, in step S103, in the i-th feeding cycle, the Tibetan chicken is fed according to the feeding feed of the i-th feeding cycle, and when i=1, the Tibetan chicken is fed using the basic feed.

[0049] For example, in the first feeding cycle, the Tibetan chicken is fed with basic feed. When i is greater than 1, the Tibetan chicken is fed according to the feeding feed of the i-th feeding cycle. The feeding feed of the i-th feeding cycle is the unadjusted feeding feed of the i-1-th feeding cycle, or the feeding feed of the i-th feeding cycle after adjusting the feeding feed of the i-1-th feeding cycle.

[0050] According to one embodiment of the present invention, in step S104, the growth data and feed consumption data of the Tibetan chicken in the i-th feeding cycle are obtained, wherein the growth data includes: weight data and fat data.

[0051] According to one embodiment of the present invention, step S104 includes:

[0052] Obtaining the consumption data of the feeding feed consumed in the i-th feeding cycle;

[0053] Sampling is performed among a plurality of Tibetan chickens currently being fed to obtain a plurality of sample Tibetan chickens;

[0054] Obtain weight data and fat data of multiple sample Tibetan chickens at multiple moments in the i-th feeding cycle.

[0055] For example, the total amount of feed consumed in the i-th feeding cycle, that is, the consumption data, is obtained; since it is difficult to detect the growth conditions of all the Tibetan chickens being fed, random sampling is performed among all the Tibetan chickens being fed to obtain multiple sample Tibetan chickens, and the growth conditions of all Tibetan chickens are determined by detecting the growth conditions of the sample Tibetan chickens; the weight data of the sample Tibetan chickens is detected at multiple moments in the i-th feeding cycle by a weighing device, and the fat content of the sample Tibetan chickens is detected by ultrasonic detection or bioelectrical impedance analysis.

[0056] According to an embodiment of the present invention, in step S105, it is determined whether the feeding feed of the i-th feeding cycle needs to be adjusted based on the growth data and the consumption data.

[0057] According to one embodiment of the present invention, step S105 includes:

[0058] Get the total number of Tibetan chickens of the multiple Tibetan chickens currently being fed;

[0059] Fitting the body weight data to multiple moments in the i-th feeding cycle to obtain a body weight data function in the i-th feeding cycle;

[0060] Determining a weight data derivative function according to the weight data function;

[0061] Determining the weight data change rate at multiple moments in the i-th feeding cycle according to the weight data derivative function;

[0062] Fitting the fat data and multiple moments in the i-th feeding cycle to obtain a fat data function in the i-th feeding cycle;

[0063] Determining a fat data derivative function according to the fat data function;

[0064] Determining the fat data change rate at multiple moments in the i-th feeding cycle according to the fat data derivative function;

[0065] Obtain historical feeding data of Tibetan fragrant chickens in historical feeding cycles, wherein the historical feeding data includes: historical age of Tibetan fragrant chickens, historical weight of Tibetan fragrant chickens, and historical feeding feed amount;

[0066] According to the historical Tibetan chicken age, determining a historical Tibetan chicken age discriminant vector;

[0067] Determine a weight growth rate function according to the historical Tibetan chicken age discriminant vector, the historical Tibetan chicken weight and the historical feeding amount;

[0068] The age of the sampled Tibetan chickens was obtained;

[0069] Determine a preset weight data change rate threshold of the sample Tibetan chicken in the i-th feeding cycle according to the sample age, the weight data, the consumption data and the weight growth rate function;

[0070] According to the preset weight data change rate threshold, the total number of Tibetan chickens, the weight data change rate, the fat data change rate, the weight data, the fat data and the consumption data, determine whether the feeding feed for the i-th feeding cycle needs to be adjusted.

[0071] For example, the total number of Tibetan chickens fed is determined; the weight data and the moments in the ith feeding cycle are fitted to obtain a weight data function for describing the law that the weight of the Tibetan chickens in the ith feeding cycle increases over time, the weight data function is differentiated to obtain a weight data derivative function, multiple moments in the ith feeding cycle are substituted into the weight data derivative function, and the weight data change rate at multiple moments in the ith feeding cycle is determined; the fat data and the moments in the ith feeding cycle are fitted to obtain a fat data function for describing the law that the fat content of the Tibetan chickens in the ith feeding cycle changes over time, the fat data function is differentiated to obtain a fat data derivative function, multiple moments in the ith feeding cycle are substituted into the fat data derivative function, and the fat data change rate at multiple moments in the ith feeding cycle is determined; the historical feeding data of historically bred Tibetan chickens is obtained from professional websites (for example, agricultural websites and animal science websites), and the historical feeding data includes: historical Tibetan chicken age (the age of the Tibetan chicken in the historical feeding cycle), historical Tibetan chicken weight (the age of the Tibetan chicken in the historical feeding cycle), and historical Tibetan chicken weight. The weight of the sample Tibetan chicken in the i-th feeding cycle is obtained, that is, the sample age; the corresponding age discriminant vector is determined according to the sample age, and the corresponding age discriminant vector, weight data and consumption data are substituted into the weight growth rate function to determine the preset weight data change rate threshold of the sample Tibetan chicken in the i-th feeding cycle; the growth and development status of the Tibetan chicken is evaluated according to the preset weight data change rate threshold, the total number of Tibetan chickens, the weight data change rate, the fat data change rate, the weight data, the fat data and the consumption data, and the growth and development status of the Tibetan chicken is determined to determine whether the feeding feed of the i-th feeding cycle needs to be adjusted.

[0072] According to one embodiment of the present invention, determining the discriminant vector of the age of a historical Tibetan fragrant chicken according to the age of the historical Tibetan fragrant chicken includes: determining the discriminant vector of the age of the historical Tibetan fragrant chicken of the jth historical Tibetan fragrant chicken according to formula (1): ,

[0073] (1)

[0074] in, is the age of the jth historical Tibetan chicken.

[0075] According to one embodiment of the present invention, in formula (1), the value of the piecewise function includes the following three cases: When the jth historical Tibetan chicken is between 0 and 30 days old, the jth historical Tibetan chicken is in the early stage, and the value of the piecewise function is ,when When the jth historical Tibetan chicken is between 30 and 180 days old, the jth historical Tibetan chicken is in a rapid growth stage, and the value of the piecewise function is ,when When the jth historical Tibetan chicken is older than 180 days, the value of the piecewise function is , the jth historical Tibetan fragrant chicken is in a mature and stable stage.

[0076] In this way, the discriminant vector of the historical age of the Tibetan fragrant chicken can be determined according to the historical age of the Tibetan fragrant chicken, and the growth stage of the Tibetan fragrant chicken can be judged according to the age of the Tibetan fragrant chicken, providing a data basis for subsequent calculations.

[0077] According to one embodiment of the present invention, a weight growth rate function is determined based on the historical Tibetan chicken age discriminant vector, the historical Tibetan chicken weight and the historical feeding amount, including: determining the equation to be fitted for the weight growth rate function according to formula (2),

[0078] (2)

[0079] in, is the discriminant vector of the jth historical Tibetan chicken’s age, for The transposed vector of is the weight of the jth historical Tibetan chicken at the end of the historical feeding cycle, is the weight of the jth historical Tibetan chicken at the beginning of the historical feeding cycle, is the number of moments of the historical feeding cycle, is the first preset weight growth rate threshold, is the second preset weight growth rate threshold, is the third preset weight growth rate threshold, is a vector determined according to the first preset weight growth rate threshold, the second preset weight growth rate threshold and the third preset weight growth rate threshold, is the historical feeding amount of the jth Tibetan chicken in the historical feeding cycle, , , , , and is the coefficient to be fitted;

[0080] Solving the coefficients to be fitted according to the historical Tibetan chicken age discriminant vector, the historical Tibetan chicken weight and the historical feeding amount of feed to obtain the solution value of the coefficients to be fitted;

[0081] The weight growth rate function is determined according to the solved values ​​of the coefficients to be fitted and the equation to be fitted.

[0082] According to one embodiment of the present invention, is the average weight growth rate of the jth Tibetan chicken in the historical feeding cycle. equal hour, The value of , is the first preset weight growth rate threshold, which indicates the preset weight growth rate of Tibetan chicken in the early stage. equal hour, The value of , is the second preset weight growth rate threshold, which indicates the preset weight growth rate of the Tibetan chicken in the rapid growth stage. equal hour, The value of , is the third preset weight growth rate threshold, indicating the preset weight growth rate of the Tibetan fragrant chicken in the mature stable stage. Indicates the preset baseline weight growth rate, It means that the average weight growth rate of the j-th historical Tibetan fragrant chicken in the historical feeding cycle and the weight of the j-th historical Tibetan fragrant chicken at the beginning of the historical feeding cycle have a negative correlation. For example, the larger the weight base of the historical Tibetan fragrant chicken, the smaller the weight change rate of the historical Tibetan fragrant chicken. is the function to be fitted in the form of an inverse tangent function. For example, when the amount of feed increases moderately, the weight growth rate of the Tibetan chicken increases with the increase of the amount of feed. When the amount of feed is greater than the food intake of the Tibetan chicken, the weight growth rate will hardly change. The equation to be fitted is determined based on the part that represents the negative correlation between the average weight growth rate and the historical Tibetan chicken weight at the starting time, as well as the part of the average weight growth rate change that conforms to the inverse tangent function form, thereby expressing the relationship between the historical Tibetan chicken age discriminant vector, the historical Tibetan chicken weight and the historical feeding amount.

[0083] According to one embodiment of the present invention, fitting can be performed based on multiple parameters involved in the above equation to be fitted, that is, fitting can be performed based on the historical Tibetan chicken age discriminant vectors, historical Tibetan chicken weights and historical feed amounts of at least 6 Tibetan chickens to solve the above multiple coefficients to be fitted. There are 6 coefficients to be fitted, namely, , , , , and According to the historical Tibetan chicken age discriminant vector, historical Tibetan chicken weight and historical feed amount, the above 6 coefficients to be fitted are solved to obtain the solution values ​​of the above 6 coefficients to be fitted, and the solution values ​​of the above 6 coefficients to be fitted are substituted into the equation to be fitted to determine the weight growth rate function.

[0084] In this way, the weight growth rate function can be determined based on the historical Tibetan chicken age discriminant vector, historical Tibetan chicken weight and historical feed amount, which accurately describes the relationship between the historical Tibetan chicken age discriminant vector, historical Tibetan chicken weight and historical feed amount, and improves the accuracy and objectivity of the weight growth rate function.

[0085] According to an embodiment of the present invention, determining whether it is necessary to adjust the feeding feed of the i-th feeding cycle according to the preset weight data change rate threshold, the total number of Tibetan chickens, the weight data change rate, the fat data change rate, the weight data, the fat data and the consumption data includes: determining the weight growth condition A, the fat growth condition B and the feed conversion condition C according to formula (3),

[0086] (3)

[0087] Among them, if is a conditional function, is the rth moment of the ith feeding cycle, is the weight data change rate of the kth sample Tibetan chicken at the rth moment of the i-th feeding cycle, is the preset weight data change rate threshold of the kth sample Tibetan chicken in the i-th feeding cycle, is the fat data change rate of the kth sample Tibetan chicken at the rth moment of the i-th feeding cycle, To preset the fat data change rate threshold, is the preset ratio threshold, is the consumption data of the feeding feed consumed in the i-th feeding cycle, is the total number of Tibetan chickens, is the weight data of the kth sample Tibetan chicken at the end of the i-th feeding cycle, is the weight data of the kth sample Tibetan chicken at the beginning of the i-th feeding cycle, is the preset conversion rate threshold, m is the number of moments in the i-th feeding cycle, r≤m, K is the number of sampled Tibetan chickens, k≤K, r, m, k and K are all positive integers;

[0088] When at least one of the weight gain condition A, the fat gain condition B and the feed conversion condition C is satisfied, it is determined that the feeding feed of the i-th feeding cycle needs to be adjusted.

[0089] According to one embodiment of the present invention, in the weight gain determination condition A of formula (3), the condition function The value of includes the following two cases, when it satisfies When the condition is met, the average weight data change rate of the kth sample Tibetan chicken in the i-th feeding cycle is greater than or equal to the preset weight data change rate threshold of the i-th feeding cycle, indicating that the weight growth of the kth sample Tibetan chicken meets the preset standard, and the value of the condition function is 1. When it does not meet the condition, When the condition is met, it means that the weight growth of the kth sample Tibetan chicken does not meet the preset standard, and the value of the conditional function is 0. The sum is calculated based on the number of sampled Tibetan chickens, which represents the ratio of the number of Tibetan chickens whose weight growth meets the preset standard to the total number of sampled Tibetan chickens. It means that the weight gain of most Tibetan chickens does not meet the preset standard, and the feeding feed in the i-th feeding cycle needs to be adjusted.

[0090] According to one embodiment of the present invention, in the fat growth determination condition B of formula (3), the condition function The value of includes the following two cases, when it satisfies When the condition is met, the average fat data change rate of the kth sample Tibetan fragrant chicken in the i-th feeding cycle is greater than or equal to the preset weight data change rate threshold of the i-th feeding cycle, indicating that the fat growth of the kth sample Tibetan fragrant chicken does not meet the preset standard, and the value of the conditional function is 1. When the condition is met, it means that the fat growth of the kth sample Tibetan chicken meets the preset standard, and the value of the conditional function is 0. The sum is calculated based on the number of sampled Tibetan chickens, indicating the ratio of the number of Tibetan chickens whose fat growth does not meet the preset standard to the total number of sampled Tibetan chickens. It means that the fat growth of most Tibetan chickens does not meet the preset standard, and the feeding feed in the i-th feeding cycle needs to be adjusted.

[0091] According to one embodiment of the present invention, in the feed conversion condition C of formula (3), represents the feed consumption of a single sample Tibetan chicken in the i-th feeding cycle, represents the weight gain of the kth sample Tibetan chicken in the i-th feeding cycle, Indicates the feed conversion rate. The larger the ratio, the better the sample Tibetan chicken absorbs the feed. The conditional function The value of includes the following two cases, when satisfying When the condition is met, the feed conversion rate of the kth sample Tibetan chicken is greater than or equal to the preset conversion rate threshold, indicating that the feed absorption condition of the kth sample Tibetan chicken is good, and the value of the condition function is 1. When the condition is , it means that the feed absorption condition of the kth sample Tibetan chicken is poor, and the value of the condition function is 0. The sum is calculated based on the number of sampled Tibetan chickens, indicating the ratio of the number of Tibetan chickens with better feed absorption to the total number of sampled Tibetan chickens. This indicates that the feed absorption of most Tibetan chickens is poor, and the feed in the i-th feeding cycle needs to be adjusted.

[0092] According to one embodiment of the present invention, when at least one of the weight gain condition A, fat gain condition B and feed conversion condition C is met, it means that the weight gain condition, fat gain condition or feed absorption condition of the sample Tibetan chicken does not meet expectations, and the feeding feed of the i-th feeding cycle needs to be adjusted.

[0093] In this way, whether the feeding feed for the i-th feeding cycle needs to be adjusted can be judged based on the preset weight data change rate threshold, the total number of Tibetan chickens, the weight data change rate, the fat data change rate, the weight data, the fat data and the consumption data. During the judgment process, the weight gain status, fat gain status and feed absorption status of the sample Tibetan chickens in the i-th feeding cycle are referred to, thereby improving the accuracy and effectiveness of the judgment results.

[0094] According to an embodiment of the present invention, in step S106, when it is determined that the feeding feed of the i-th feeding cycle needs to be adjusted, the feeding feed of the i+1-th feeding cycle is determined according to the growth data and the consumption data.

[0095] According to one embodiment of the present invention, step S106 includes:

[0096] Under the condition that the weight gain condition A is met, determining to increase the proportion of protein feed;

[0097] Under the condition that the fat growth condition B is met, determine to reduce the amount of oil feed added;

[0098] Under the condition that the feed conversion condition C is met, it is determined to add feed additives.

[0099] For example, if weight gain condition A is met, it means that the weight gain of the Tibetan chicken currently being fed is too slow. On the basis of the feed in the i-th feeding cycle, the proportion of protein feed is increased according to a preset ratio (e.g., 10% of the previous content), such as increasing the proportion of plant protein feed from 10% of the total feed to 11%. The increase should not be too much, as too much protein will burden the stomach and intestines of the Tibetan chicken. If fat gain condition B is met, it means that the fat content of the Tibetan chicken currently being fed is too high. On the basis of the feed in the i-th feeding cycle, the amount of oil feed added is reduced according to a preset ratio, such as reducing the amount of oil feed added from 5% of the total feed to 4.5%. If feed conversion condition C is met, it means that the feed absorption of the Tibetan chicken currently being fed is poor. Feed additives (probiotics and enzyme preparations) are added according to a preset ratio, such as increasing the proportion of probiotics from 0.1% of the total feed to 0.11%, and increasing the proportion of enzyme preparations from 0.04% of the total feed to 0.044%, so as to improve the utilization rate and digestion and absorption rate of feed.

[0100] According to one embodiment of the present invention, in step S107, in the (i+1)th feeding cycle, the Tibetan chicken is fed according to the feeding feed of the (i+1)th feeding cycle.

[0101] For example, in the i+1th feeding cycle, the Tibetan chicken is fed using the feeding feed determined in the i+1th feeding cycle.
