Pollution-free laying hen breeding feed

Abstract

The invention discloses belongs to pollution-free laying hen breeding feed, belongs to the field of laying hen feed, and aims to provide the non-harmful, non-residual, and nutrient balanced laying hen breeding feed. The technical scheme adopted is that the pollution-free laying hen breeding feed is matched by the following raw materials in part by weight: 300-350 parts of maize, 80-90 parts of soybean meal, 60-70 parts of bran, 4-6 parts of rock flour, 3-4 parts of hydrogen and calcium, 2-5 parts of methionine, 0.1-1 parts of lysine, 0.1-1 parts of phytase, 5-15 parts of salt, and 1-10 parts of premix. A laying hen fed by adopting the feed has higher qualified rate in tibia length and weight, good chicken uniformity, and high later period egg laying rate.

Description

technical field [0001] The invention belongs to the field of laying hen feed, and in particular relates to a feed for laying hens in the growing period. Background technique [0002] The rearing period is a critical period for the development of the bones, muscles, and physiological organs of laying hens, and it is the stage for laying the foundation for the laying period. During the rearing period, whether the group shape, body weight, and uniformity of the chickens reach the standard will directly affect the egg production performance. . Many chicken farmers think that young chickens do not lay eggs and do not need to eat good feed. They do everything possible to reduce the feeding cost of young chickens and use cheap feed. As a result, the chickens are approaching the production period, the weight is not up to the standard, and the uniformity of the flock is also poor. , the tibia is short, the individual is small, and it is prone to paralysis, dystocia, rectal prolapse ...

Problems solved by technology

Many chicken farmers think that young chickens do not lay eggs and do not need to eat good feed. They do everything possible to reduce the feeding cost of young chickens and use cheap feed. As a result, the chickens are approaching the production period, the weight is not up to the standard, and the uniformity of the flock is also poor. , the tibia is short, the individual is small, and it is prone to paralysis, dystocia, rectal prolapse after the start of labor, the egg production rate rises very slowly, and the egg production rate is difficult or cannot reach the peak
