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] Adopt described method to carry out practice respectively in broiler breeder great-grandfather generation, grandparents, parents generation farm of certain chicken farm, the uniformity of each farm flock can reach more than 95% at the end of 9 weeks of age, each farm chicken flock later stage The egg production performance all reached the variety breeding target.

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

[0076] For 4-week-old to 9-week-old chickens, it is usually enough to group them once on the first day of 5 weeks to avoid adverse effects such as operating costs and chicken stress reactions caused by frequent grouping. Evaluate and adjust the feeding amount once a day, and at the same time, evaluate and adjust the feeding method based on the weight uniformity of the chickens in the same group / cage. However, it can be understood that, according to act...

Abstract

The invention relates to a method for improving uniformity of cage-reared broiler breeders in a growing period. The method comprises the following steps: 1) determining of grouping weight ranges: dividing a plurality of groups of grouping weight ranges according to a standard weight of a chicken flock at corresponding week ages; 2) chicken flock grouping: measuring the weight of each chicken in the chicken flock one by one, grouping the chicken flock according to the grouping requirement in the step 1), and calculating the average weight of each group of chickens; (3) calculation of feeding amount: calculating the daily feeding amount of each group of chickens from the corresponding week age to the 9 week age according to the average weight of each group of chickens, the standard weight of each week age, and the standard daily gain and the reference daily ration level from the corresponding week age to the 9 week age; and 4) feeding: feeding each group of chickens according to the daily feeding amount of each group of chickens. The chicken flocks is grouped according to the actual weight of the chicken individuals, the chicken flock is fed according to the feeding amount difference in a period of time, the weight of each group of chickens at the end of the breeding period can reach the standard weight of the target week age, and therefore the overall uniformity of the chicken flock is improved.

Description

technical field [0001] The invention relates to a method for improving the uniformity of broiler breeders raised in cages, and belongs to the technical field of breeding. Background technique [0002] The cage breeding mode of broiler breeders is the main mode of broiler breeder breeding in the future, and it has greater advantages than the flat breeding mode in terms of land utilization rate, flock survival rate, disease purification, fertilization rate and egg production rate. In the production management process of broiler breeders brooding and rearing stages, body weight is the basis for the growth and development of chickens, and uniformity is the key to the performance and economic benefits of breeder flocks. [0003] During the breeding and management of broiler breeders, because broiler breeders grow fast, consume a large amount of feed, and deposit fat quickly, during production, the feed distribution method of limited feeding is usually adopted. Give the chickens ...
