Management method for increasing double-yolk egg laying rate of broiler breeder hens

Abstract

The invention discloses a management method for increasing a double-yolk egg laying rate of broiler breeder hens. The management method includes illumination management and feeding management, and feeding management includes a feeding method and feed additive management. Compared with the prior art, the management method has advantages that light increase is performed on the broiler breeder hens and regulated repeatedly, a feed addition rate is increased, decreased and increased again sequentially, proper feed additives are added at corresponding stages, and consequently development conditions of the hens are enhanced, energy accumulation is promoted, egg yield and double-yolk egg laying rate of the broiler breeder hens are increased, healthiness and egg laying persistence of the hens are kept, qualified hatching egg yield is guaranteed, and economic benefits are increased for farmers.

Description

technical field [0001] The invention belongs to the technical field of agricultural breeding, and particularly relates to a management method for improving the double-yolk egg production rate of broiler breeders. Background technique [0002] Double yolk eggs are more nutritious than ordinary eggs, in which lecithin, amino acids and free fatty acids are more than ten times more than ordinary eggs. However, due to lack of management experience, the yield of double yolk eggs is low, and the impact of feed management and light management at each stage With regard to the egg production rate and the yield of double-yolked eggs, in the prior art, when the egg production rate of breeders reaches 5%, the pubic spacing reaches two fingers, and the development of breast muscles and energy accumulation are both insufficient. The probability of double-yolked eggs is likely to cause discomfort in breeders, resulting in a decline in egg production and affecting the fertilization rate and ...

Problems solved by technology

[0002] Double-yolk eggs are more nutritious than ordinary eggs, including more than ten times more lecithin, amino acids and free fatty acids than ordinary eggs. According to the egg production rate and the output of double-yolk eggs, when the egg production rate of the breeder chicken reaches 5%, the distance between the pubis reaches two fingers in the existing technology, and the breast muscle development and energy accumulation are not enough. The probability of double yolk eggs is likely to cause discomfort to the breeder, resulting in a decrease in egg production, affecting the fertilization rate and egg production rate after the peak period
