The invention relates to a feed for feeding large-type adult cock breeders in adult stage. The feed for large-type adult cock breeders is free of fish meal. The ingredients in weight percentages of the feed are as follows: 1% to 6% of special premixed feed, 60% to 80% of corn, 15% to 20% of bean cake, 1% to 2% of calcium hydrogen phosphate, 0.3% to 0.5% of table salt, 10% to 15% of wheat, and 0.1% of methionine. Take the AA+ broiler breeder of parent generation as an example, after feeding on the feed, the peak fertilization rate of breeder egg in the chicken breeders is increased by 1.5%, and the fertilization rate of breeder egg in the full reproductive period is increased by 3%. Take the breeding farm capable of breeding 0.1 million heads of chicken breeders per year as an example, theyield of fertilized eggs is increased by 0.3 millions per year and the revenue reaches 0.45 million Yuan. Calculated on basis of breeding 30 million heads of chicken breeders per year throughout the country, the revenue reaches 0.45 billion RMB, with considerable economic benefits.

The invention discloses a light breeding method for controlling the sexual maturity of high-quality broiler breeders. The light time of the first 3 days is 23L-1D, and the light intensity is 100Lx. From the 4th day, the light time is reduced by 2h every day, and the light intensity is reduced by 10Lx every day, until 4 weeks At the end of age, the light time and intensity were 8 L-16D and 8 Lx respectively; from the 5th week, the light time was 8 L-16D every day, and the light intensity was 8lx, and continued until the end of the 14th week; Add 2 hours per week, and the light intensity remains unchanged. When the production starts, the light time is 16L-8D, and the light intensity is 10Lx, and the light time is increased by 2h every week; from the 20th week, the daily light time is 18L-8D, and the light intensity is 30Lx. The light intensity continued to increase by 10Lx every week until the end of 66 weeks. After adopting this light culture method, the age of 5% of the chicken flocks was advanced by 10-12 days, and the weight of 5% of the flocks was increased by 50-60g, and the age of the whole flock was advanced by 10-14 days. Weight increased by 40g to 50g.

The invention relates to a method for improving the uniformity of caged broiler breeders during the breeding period, comprising the following steps: 1) determining the group weight range: dividing the group weight ranges of several components according to the standard body weight of the corresponding age of the chicken group; 2) grouping the chicken group into groups : Measure the body weight of each chicken in the flock, group the chickens according to the grouping requirements of step 1), and calculate the average weight of the chickens in each group; 3) Calculate the feeding amount: according to the grouping requirements of each group of chickens Average body weight, standard body weight of each week, standard daily gain and reference diet level from the corresponding week to 9 weeks, and calculate the daily feeding amount of each group of chickens from the corresponding week to 9 weeks; 4) Feeding: Feed the chickens in each group separately according to the daily feeding amount of the chickens in each group. The method divides the chicken groups into groups according to the actual body weight of the individual chickens, and feeds them with different feeding amounts for a period of time, so that the weight of the chickens in each group at the end of the breeding period can reach the standard body weight of the target age, thereby improving the overall chicken group. uniformity.

The invention provides an automatic broiler breeder raising greenhouse for polyculture and separate feeding of roosters and hens. The greenhouse comprises a reelable thermal insulation cover layer which is controlled by a temperature sensor in the greenhouse and is positioned on an illumination surface on the top of the greenhouse, and feeding units which consist of a plurality of groups of online platforms in the greenhouse; the front sides of the feeding units are provided with upper and lower troughs and grids in different widths according to physiological difference of the roosters and the hens, and the back parts of the feeding units are connected with breeder bionic egg laying nests for automatically collecting eggs to stop out-nest eggs; egg collectors and conveyer belts are arranged below the egg laying nests, so automatic egg collection is realized and the yield of the eggs is improved. According to the greenhouse, the production cost can be effectively reduced, one-time automatic feeding of the roosters and the hens with different feeds and in different quantities is realized, the aims of polyculture, separate feeding and natural insemination of the roosters and the hens are fulfilled, infection caused by human intervention is avoided, and manpower and material sources are saved.
