Problems solved by technology

However, in the actual feed distribution process, it is impossible to weigh the feed distribution one by one, and only adopt group weighing and distribution, which will cause uneven feed intake and weight differences among the chickens, resulting in poor growth and development uniformity of the chicken flock , affecting the normal performance of the flock's production performance

experiment example

[0074] Using the method described in the practice of the great-grandparents, grandparents and parents of broiler breeders in a chicken farm, the uniformity of the chickens in each farm can reach more than 95% at the end of 9 weeks of age. The egg-laying performance all reached the breeding target.

[0075] It can be understood that, according to the feeding control accuracy, the growth time of the chickens can also be calculated in units of day age and the like.

[0076] For 4-week-old to 9-week-old flocks, one-time grouping is usually done on the first day of 5-week-old flocks to avoid the adverse effects of frequent groupings such as operating costs and chicken stress response. The feeding amount can be evaluated and adjusted once a day, and the feeding method can also be evaluated and adjusted for the weight uniformity of the chickens in the same group / coop. However, it can be understood that, according to actual needs or operating conditions, it is also possible to perfor...

Abstract

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.

Description

technical field [0001] The invention relates to a method for improving the uniformity of caged broiler breeders during the breeding period, and belongs to the technical field of breeding. Background technique [0002] The broiler breeder cage model is the main mode of broiler breeder breeding in the future, and it has greater advantages than the flat breeding model in terms of land utilization, flock survival rate, disease purification, fertilization rate and egg production rate. In the production management process of broiler breeders in the brooding and rearing stages, body weight is the basis for the growth and development of chickens, and uniformity is the key to the production performance and economic benefits of breeder chickens. [0003] In the process of feeding and management of broiler breeders, due to the rapid growth and development of broiler breeders, large feed intake, and rapid fat deposition, during production, the feed distribution method with restricted fe...
