Description

Technical Field

[0001] This invention relates to the field of broiler breeding technology, and in particular to a method for raising and managing 901PLUS parent broiler breeders. Background Technology

[0004] The 901 strain and similar breeds represent significant achievements of my country's broiler breeding strategy and pursuit of self-sufficiency in breeding stock. Their genetic background, breeding objectives, and physiological metabolic mechanisms differ fundamentally from foreign breeds. This dictates that their optimal feeding programs must also be unique. While basic feeding and management principles are similar, directly applying foreign standards to specific technical parameters has proven risky in practice.

[0005] Therefore, the core pain point and urgent need in the current market has shifted from the application of mature technologies to the innovative research and development and systematic establishment of supporting feeding technologies for domestic breeds. This requires a systematic study of the production performance of the 901 strain under different nutritional levels and feeding models, ultimately forming a data-driven "Chinese solution" that can accurately unleash its genetic potential. The successful establishment of this technology is not only key to the 901 strain gaining a foothold in market competition, but also a fundamental guarantee for promoting the historic leap of my country's broiler chicken industry from "importing" to "self-reliance." Summary of the Invention

[0006] The purpose of this invention is to provide a method for raising and managing 901PLUS parent broiler breeders, in order to solve the problems in the existing technology where the raising and management methods of 901 are not compatible with those of foreign white-feathered broiler breeders and there is a lack of supporting raising and management methods that can ensure its performance.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A method for raising and managing 901Plus parent broiler breeders, the core of which is: based on the floor-raising model, setting egg production targets and weight standards according to the age of the breeders, matching the feed nutrition level and feed amount according to these standards, and adopting different feeding methods, lighting and other management measures for hens and roosters respectively.

[0008] Furthermore, the amount of feed was increased for hens before they reached 33 weeks of age, and then the amount of feed was reduced after they reached 33 weeks of age.

[0009] Furthermore, during the first three weeks, the hens were fed the first-stage brooding feed, which had a metabolizable energy of 2820 kcal / kg and a crude protein content of 19%. Each hen was fed 23g of feed in the first week and weighed 150g; 30g of feed in the second week and weighed 290g; and 32g of feed in the third week and weighed 410g. During the first week, the hens were allowed free access to feed, while during the second and third weeks, they were fed a restricted diet. During weeks 4-6, feed the second stage brooding feed, which has a metabolizable energy of 2800 kcal / kg and a crude protein content of 17%. Each hen is fed 34g in week 4 and weighs 510g; 36g in week 5 and weighs 610g; and 38g in week 6 and weighs 705g. During week 4, adopt a daily restricted feeding method, and during weeks 5-6, adopt a 6 / 1 restricted feeding method.

[0010] Furthermore, during weeks 7-15, hens are fed a first-stage growing feed with a metabolizable energy of 2720 kcal / kg and a crude protein content of 14%. The feed amount per hen increases from 40g to 72g, with a weekly increase of 2-6g, and the hen's weight reaches 750-1570g. During this period, a 5 / 2 restricted feeding method is adopted. During weeks 16-20, hens are fed a second-stage growing feed with a metabolizable energy of 2830 kcal / kg and a crude protein content of 13.6%. The feed amount per hen increases from 80g to 104g, with a weekly increase of 2-8g, and the hen's weight reaches 1720-2400g. During this period, a 5 / 2 restricted feeding method is adopted.

[0011] Furthermore, during weeks 21-24, the hens were fed a pre-laying diet with a metabolizable energy of 2860 kcal / kg and a crude protein content of 13.6%. The calcium content in the feed was also appropriately increased, with the feed amount per hen increasing from 106g to 110g. In weeks 21-22, the amount was increased by 4g, and then by 1g per week thereafter, until the hen's weight reached 2600-3150g. During weeks 21-22, a 6 / 1 restricted feeding method was adopted, and during weeks 23-24, a daily restricted feeding method was adopted.

[0012] Furthermore, after the laying rate reaches 5%, hens are fed a laying period feed. Specifically, hens are fed a laying period feed from weeks 25 to 35, with a metabolizable energy of 2860 kcal / kg and a crude protein content of 15.0%. The feed amount per hen increases from 112g to 160g, continuing from weeks 25 to 29. The feed amount remains stable until the end of week 33. Starting from week 34, the feed amount is gradually reduced based on changes in laying rate, egg weight, and body weight. In weeks 34 and 35, the feed amount is reduced by 1g per hen per week, with a body weight of 3... 290-3870g; From 36-50 weeks, use the second-stage laying feed, which has a metabolizable energy of 2860Kcal / kg and a crude protein content of 14.0%. The feed amount per hen is 160g-151g, and the weight is 3890-4090g; From 51 weeks until culling, use the third-stage laying feed, which has a metabolizable energy of 2860Kcal / kg and a crude protein content of 13.0%. The feed amount per hen is 151-146g, and the weight is 4100-4230g.

[0013] Furthermore, during weeks 1-3, roosters were fed a brooding diet with a metabolizable energy of 2820 kcal / kg and a crude protein content of 19%. Each rooster received 26g of feed in week 1, resulting in a weight of 166g; 42g in week 2, resulting in a weight of 369g; and 55g in week 3, resulting in a weight of 590g. During weeks 1 and 2, roosters were allowed free access to feed daily, while during week 3, they were fed a restricted diet daily. The feeding method is as follows: From week 4 to week 6, feed the second-stage brooding feed, which has a metabolizable energy of 2800 kcal / kg and a crude protein content of 17%. Each rooster receives 56g of feed in week 4, reaching a weight of 768g; 60g in week 5, reaching a weight of 942g; and 62g in week 6, reaching a weight of 1150g. A daily restricted feeding method is used in week 4, and a 5 / 2 restricted feeding method is used in weeks 5 and 6. From weeks 7 to 15... The roosters were fed a first-stage growing diet with a metabolizable energy of 2720 kcal / kg and a crude protein content of 14%. The feed amount per rooster increased from 63g to 89g, with a weekly increase of 2-5g, resulting in a body weight of 1279-2344g. During this period, a 5 / 2 restricted feeding method was used. From weeks 16 to 24, the roosters were fed a second-stage growing diet with a metabolizable energy of 2830 kcal / kg and a crude protein content of 13.6%. Each rooster's feed intake was increased from 95g to 115g, with a weekly increase of 2-6g, resulting in a weight of 2500-3700g. During this period, a 5 / 2 restricted feed method was used from weeks 16-19, and a 6 / 1 restricted feed method was used from weeks 20-24. From week 25 onwards, roosters were fed rooster feed with a metabolizable energy of 2800Kcal / kg and a crude protein content of 12%, fed daily, resulting in a weight of 3820-4800g.

[0014] Furthermore, during the first week of brooding, the hens were given 24 hours of light on the first day, 23 hours of light per day on days 2-4 with a light intensity of 60 Lux on days 5-7, 1 hour less per day to 20 hours per day with a light intensity of 60 Lux on days 8-18, 8 hours of light per day to 8 hours per day, 2 hours less per day, with a light intensity of 60 Lux on days 19-154, 8 hours of light per day with a light intensity of 2-3 Lux, until the first supplemental lighting was introduced.

[0015] Furthermore, during the first week of brooding, the roosters should receive 24 hours of light on the first day, and 23 hours of light per day with a light intensity of 60 Lux from the second to the fourth day. From the fifth to the seventh day, the light duration should be reduced by 1 hour to 20 hours per day with a light intensity of 60 Lux. During the second week, the roosters should receive 20 hours of light per day with a light intensity of 60 Lux. From the 15th to the 28th day, the light duration should be gradually reduced from 18 hours to 8 hours, decreasing by 2 hours every other day with a light intensity of 60 Lux. From the 26th to the 154th day, the light duration should be 8 hours per day with a light intensity of 2-3 Lux. The specific adjustments should be made based on the roosters' weight; if the weight is below the standard, the light duration should be increased.

[0016] Furthermore, roosters and hens were separated and raised separately until 21 weeks of age, after which they were mixed together. At the end of the 22nd week (154 days), the growth and development of the flock were assessed. When more than 90% of the chickens met the four criteria for additional lighting, the first light stimulation of 12 hours was carried out. About 7 days after the first light stimulation, a second light stimulation of 13 hours was carried out. When the egg production rate of the breeding chickens reached 50%, a third light stimulation was carried out, and the final lighting time for the flock was fixed at 14 hours.

[0017] Compared with the prior art, the significant technical effects of the present invention are as follows: 1. This invention is based on floor-raising, and through precise formulation and accurate control of feed amount, it achieves high egg production rate by making the breeder chickens weigh a reasonable weight, thereby improving production efficiency and providing a reference for the breeding and management of domestic breeds.

[0018] 2. By rationally configuring the duration and intensity of light, the hens were able to start laying eggs on time, extend the peak laying period, increase the egg production rate, and increase the total egg production. Attached Figure Description

[0019] Figure 1 This is a flowchart illustrating a method for raising and managing 901PLUS parent broiler breeders proposed in this invention. Detailed Implementation

[0020] Example 1 See attached document Figure 1This invention discloses a method for raising and managing 901Plus parent broiler breeders. Based on the floor-raising model, the method sets egg production indicators and weight standards according to the age of the breeders, and matches the feed nutrition level and feed amount according to these standards. Different feeding methods and lighting management measures are adopted for hens and roosters respectively.

[0021] In the specific feeding and management process, taking hens as an example, the specific feeding and management methods are as follows: (I) Brooding period (weeks 1-6) During the first three weeks of the brooding period, the chicks were fed a first-stage brooding feed with a metabolizable energy of 2820 kcal / kg and a crude protein content of 19%. Each hen was fed 23g of feed in the first week, reaching a weight of 150g; 30g in the second week, reaching a weight of 290g; and 32g in the third week, reaching a weight of 410g. During the first week, the chicks were allowed free access to feed daily, while during the second and third weeks, a restricted feeding method was used daily.

[0022] During weeks 4-6, feed the second stage brooding feed, which has a metabolizable energy of 2800 kcal / kg and a crude protein content of 17%. Each hen is fed 34g in week 4 and weighs 510g; 36g in week 5 and weighs 610g; and 38g in week 6 and weighs 705g. During week 4, adopt a daily restricted feeding method, and during weeks 5-6, adopt a 6 / 1 restricted feeding method.

[0023] Regarding lighting management, the hens were given 24 hours of light on the first day; 23 hours of light per day from the second to the fourth day, with a light intensity of 60 Lux; from the fifth to the seventh day, the light duration was gradually reduced from 23 hours to 20 hours, with a light intensity of 60 Lux; from the eighth to the eleventh day, the light duration was rapidly reduced from 18 hours to 8 hours, decreasing by 2 hours every other day, with a light intensity of 60 Lux.

[0024] (II) Growth Period (Weeks 7-20) During the first rearing period (weeks 7-15), the chickens were fed a rearing feed with a metabolizable energy of 2720 kcal / kg and a crude protein content of 14%. The feed amount per hen was increased from 40g to 72g, with a weekly increase of 2-6g. The chickens' weight was 750-1570g. During this period, a 5 / 2 restricted feeding method was adopted.

[0025] During the second rearing period (weeks 16-20), to support the development of the reproductive system, the hen is fed a second-stage rearing feed with a metabolizable energy of 2830 kcal / kg and a crude protein content of 13.6%. The feed amount per hen is increased from 80g to 104g, with a weekly increase of 2-8g, and the hen's weight is 1720-2400g. During this period, a 5 / 2 restricted feeding method is adopted.

[0026] From day 19 to day 154, short-day conditions of 8 hours were maintained, and light intensity was reduced to a suppression level of 2-3 Lux.

[0027] (III) Expected delivery date (weeks 21-24) The period from week 21 to week 24 of the pre-laying period is a critical window for achieving uniformity in laying. Feed the hen a pre-laying period diet with a metabolizable energy of 2860 kcal / kg and a crude protein content of 13.6%, with an appropriate increase in calcium content. Increase the feed amount per hen from 106g to 110g, then increase by 4g in weeks 21-22, and then by 1g per week thereafter, until the hen reaches a weight of 2600-3150g. Use a 6 / 1 restriction feeding method in weeks 21-22, and a daily restriction feeding method in weeks 23-24.

[0028] (iv) Laying period (from week 25 to culling) Once an individual's egg production rate reaches 5%, the system automatically switches it to the egg production period management program.

[0029] Use a first-stage laying feed from weeks 25 to 35, with metabolizable energy of 2860 kcal / kg and crude protein of 15.0%. The feed amount per hen should be increased from 112g to 160g from week 25 to week 29, and then kept stable until week 33.

[0030] Starting from the peak egg production period in week 34, strictly control the weight to prevent excessive fat deposition. Beginning in week 34, gradually reduce the feed amount based on changes in egg production rate, egg weight, and body weight. Reduce the feed amount by 1g per chicken per week in weeks 34 and 35, with a body weight of 3290-3870g.

[0031] Use a second-stage laying feed from 36 to 50 weeks of age. The metabolizable energy is 2860 kcal / kg, the crude protein content is 14.0%, the feed amount per hen is 160g-151g, and the body weight is 3890-4090g. From week 51 until culling, use a three-stage laying feed with a metabolizable energy of 2860 kcal / kg and a crude protein content of 13.0%. The feed amount per hen is 151-146g, and the body weight is 4100-4230g.

[0032] The management of roosters follows a similar method, but it has been adapted to their unique physiological characteristics. The specific feeding and management methods for roosters are as follows: (I) Brooding period (weeks 1-6) During weeks 1-3, feed the first-stage brooding diet, with a metabolizable energy of 2820 kcal / kg and crude protein of 19%. Week 1: 26g feed, weight 166g; Week 2: 42g feed, weight 369g; Week 3: 55g feed, weight 590g. Allow free access to feed during weeks 1 and 2, and restrict feed daily during week 3.

[0033] From weeks 4 to 6, feed the second stage brooding feed, with a metabolizable energy of 2800 kcal / kg and a crude protein content of 17%. In week 4, the feed intake is 56g, and the body weight is 768g, using a daily feed restriction method; in week 5, the feed intake is 60g, and the body weight is 942g; in week 6, the feed intake is 62g, and the body weight is 1150g. From weeks 5 to 6, a 5 / 2 feed restriction method is used.

[0034] Regarding lighting management, roosters received 24 hours of light on day 1; 23 hours daily from day 2 to 4, with a light intensity of 60 Lux; from day 5 to 7, the light duration was gradually reduced from 23 hours to 20 hours, with a light intensity of 60 Lux. Particularly important was maintaining a long light duration of 20 hours and a light intensity of 60 Lux from day 8 to 14 to promote feed intake and skeletal development. From day 15 to 28, the light duration was gradually reduced from 18 hours to 8 hours, decreasing by 2 hours every other day, with a light intensity of 60 Lux.

[0035] (II) Growth Period (Weeks 7-24) From weeks 7 to 15, the chickens were fed a growth-stage feed with a metabolizable energy of 2720 kcal / kg and a crude protein content of 14%. The feed amount per rooster was increased from 63g to 89g, with an increase of 2-5g per week, and the weight ranged from 1279 to 2344g. A 5 / 2 restricted feeding method was adopted.

[0036] From weeks 16 to 24, feed the second-stage growing diet, with a metabolizable energy of 2830 kcal / kg and crude protein of 13.6%. Increase the feed amount per rooster from 95g to 115g, with an increase of 2-6g per week, until the rooster's weight reaches 2500-3700g. Use a 5 / 2 restricted feed method from weeks 16 to 19, and a 6 / 1 restricted feed method from weeks 20 to 24.

[0037] From day 26 to day 154, the daily light duration is 8 hours, and the light intensity is 2-3 Lux. During the rearing period, if some roosters do not meet the weight gain target, the light duration in their respective zones will be temporarily increased by 1-2 hours from the 8 hours to stimulate their feeding and activity until their weight catches up with the target.

[0038] Roosters and hens were separated and raised until 21 weeks of age, after which they were mixed together. At the end of the 22nd week (154 days), the growth and development of the flock were assessed. When more than 90% of the chickens met the four criteria for light stimulation (pubic bone opening 3.5 mm and smoothness, fat deposition 1.2-1.3 mm, weight and energy intake meeting standards), the first light stimulation of 12 hours was carried out. About 7 days after the first light stimulation, the second light stimulation of 13 hours was carried out. When the egg production rate of the breeder chickens reached 50%, the third light stimulation was carried out, and the final light time for the flock was fixed at 14 hours.

[0039] (III) Adulthood (Week 25 to Elimination) From week 25 until culling, roosters were fed rooster feed with 2800 kcal / kg metabolizable energy and 12% crude protein, on a daily basis, with a body weight of 3820-4800g. The aim was to breed a group of roosters with strong physiques, moderate libido, and no excessive weight to maintain their sexual function and health, while strictly preventing obesity in the later stages.

[0040] Example 2: Comparative Experiment To verify the practical effectiveness of the 901Plus parent broiler breeder rearing and management method disclosed in this invention, a 65-week comparative experiment was conducted from March 2022 to May 2024 at a national-level core broiler breeding farm. A total of 4,400 901Plus parent broiler chicks of the same batch, with consistent health status and weight uniformity, were randomly divided into an experimental group and a control group, with 2,000 hens and 200 roosters in each group.

[0041] Experimental Group (Example 2): The feeding and management method of this invention was adopted. Egg production targets and weight standards were established according to the age of the breeding chickens, and feed nutrient levels and feed amounts were matched accordingly. Different feeding methods and lighting management measures were implemented for hens and roosters respectively. Specific feeding and management methods are as described above.

[0042] Control group (Comparative Example 2): The chicken farm adopted its current standardized feeding and management procedures, representing the advanced level in the industry. These procedures were based on the 901Plus official feeding manual and managed on a weekly basis. Each week, 5% of the chickens in the flock were randomly selected for weighing, and the weekly feed intake for the entire flock was adjusted uniformly based on the difference between the average weight and the standard weight curve. Feeding was done via feed line, with the entire flock fed uniformly. Lighting management adopted a uniform "one-size-fits-all" approach, with the entire flock receiving its first light stimulation at a fixed age, i.e., week 23.

[0043] During the experiment, the feed ingredients, vaccination procedures, daily management personnel, and rearing environment (temperature, humidity, ventilation) were kept highly consistent between the two groups. After the experiment, the overall production performance data of the two groups were statistically analyzed, and the results are shown in the table below.

[0044] Table 1: Comparison of key production performance indicators between Example 2 and Comparative Example 2 at 65 weeks of age Performance indicators Comparative Example 2 (Traditional Standardized Management) Example 2 (Method of the Invention) Improvement rate / Enhancement rate Egg production of hens entering the coop (eggs / HH) 268.5 291.3 +8.49% Weekly egg production rate during peak egg production 89.2% 92.6% +3.4% Egg qualification rate 94.1% 96.5% +2.4% Average fertilization rate throughout the period 92.8% 95.7% +2.9% Average hatching rate (percentage of fertilized eggs) throughout the entire period 91.5% 93.8% +2.3% The number of qualified chicks provided per hen 219.7 240.0 +9.23% Body weight uniformity (CV%) in 65-week-old hens 9.8% 6.2% Improvement of 36.7% Feed conversion ratio (feed / chicken eggs) for breeder hens throughout the breeding period 2.65:1 2.41:1 Improvement of 9.06% As can be seen from the data in the table above, compared with Comparative Example 2 which uses traditional standardized management methods, Example 2 using the method of this invention shows significant advantages in all key production performance indicators. The number of eggs laid by hens increased by 3.4%, mainly due to a higher peak laying period and a longer production cycle. The number of qualified chicks provided per hen also saw a significant increase of 9.23%, reflecting the comprehensive advantages in egg production, hatching egg qualification rate, fertilization rate, and hatchability. Crucially, the uniformity of hen weight was greatly improved, fully demonstrating that this invention, through individualized and precise control, can effectively avoid poor individual development or excessive obesity caused by group rearing, thereby significantly improving the overall health and lifespan of the breeding flock. The improved feed conversion ratio also indicates that the method of this invention can more efficiently convert nutrients into production performance, reducing feeding costs.

[0045] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.

Each rooster received 26g of feed in week 1, resulting in a weight of 166g; 42g in week 2, resulting in a weight of 369g; and 55g in week 3, resulting in a weight of 590g. During weeks 1 and 2, roosters were allowed free access to feed daily, while week 3 was fed a restricted diet. From weeks 4 to 6, feed the second-stage brooding feed, which has a metabolizable energy of 2800 kcal / kg and a crude protein content of 17%. Each rooster receives 56g of feed in week 4, reaching a weight of 768g; 60g in week 5, reaching a weight of 942g; and 62g in week 6, reaching a weight of 1150g. A daily restricted feeding method is used in week 4, and a 5 / 2 restricted feeding method is used in weeks 5 and 6. From weeks 7 to 15, feed... The first-stage growing feed was given to roosters with a metabolizable energy of 2720 kcal / kg and a crude protein content of 14%. The feed amount per rooster increased from 63g to 89g, with a weekly increase of 2-5g, resulting in a body weight of 1279-2344g. During this period, a 5 / 2 restricted feeding method was used. From weeks 16 to 24, the roosters were fed the second-stage growing feed, with a metabolizable energy of 2830 kcal / kg and a crude protein content of 13.6%. The feed amount for each rooster was increased from 95g to 115g, with a weekly increase of 2-6g, and the weight reached 2500-3700g. During this period, a 5 / 2 restricted feed method was used from weeks 16 to 19, and a 6 / 1 restricted feed method was used from weeks 20 to 24. From week 25 onwards, roosters were fed rooster feed with a metabolizable energy of 2800Kcal / kg and a crude protein content of 12%, on a daily feeding basis, and the weight reached 3820-4800g.

8. The feeding method according to claim 2, characterized in that: During the first week of brooding, the hens are given 24 hours of light on the first day. From the second to the fourth day, the hens are given 23 hours of light per day at a light intensity of 60 Lux. From the fifth to the seventh day, the light duration is reduced by 1 hour to 20 hours per day at a light intensity of 60 Lux. From the eighth to the 18th day, the light duration is reduced from 18 hours to 8 hours per day, with a reduction of 2 hours every other day at a light intensity of 60 Lux. From the 19th to the 15th day, the light duration is 8 hours per day at a light intensity of 2-3 Lux, until the first supplemental lighting is introduced.

9. The feeding method according to claim 1, characterized in that: During the first week of brooding, roosters should receive 24 hours of light on day 1, and 23 hours of light per day with a light intensity of 60 Lux from day 2 to day 4. From day 5 to day 7, the light duration should be reduced by 1 hour to 20 hours per day with a light intensity of 60 Lux. During the second week, 20 hours of light should be provided for 7 days with a light intensity of 60 Lux. From day 15 to day 28, the light duration should be gradually reduced from 18 hours to 8 hours, decreasing by 2 hours every other day with a light intensity of 60 Lux. From day 26 to day 154, the light duration should be 8 hours per day with a light intensity of 2-3 Lux. The specific adjustments should be made based on the roosters' weight; if the weight is below the standard, the light duration should be increased.

10. The feeding method according to claim 6, characterized in that: At the end of the 22nd week (154 days), the growth and development of the flock were assessed. When more than 90% of the chickens met the four criteria for light stimulation, the first light stimulation of 12 hours was carried out. About 7 days after the first light stimulation, the second light stimulation of 13 hours was carried out. When the egg production rate of the breeder chickens reached 50%, the third light stimulation was carried out, and the final light time of the flock was fixed at 14 hours.
