Breeding method for improving hatchability of yellow feather broilers

Abstract

The invention discloses a breeding method for improving hatchability of yellow feather broilers. A breeding feed of the yellow feather broilers and a breeding method of the yellow feather broilers are involved. The breeding feed of the yellow feather broilers is prepared from, by weight, 63-67 parts of corn, 21-25% of 46% bean pulp, 4-6 parts of extruded soybeans, 2.8-3.2 parts of soybean oil, 1.4-1.7 parts of mountain flour, 0.8-1 part of calcium hydrophosphate, 0.2-0.4 part of sodium chloride, 0.05-0.08 part of 99% methionine, 0.02-0.04 part of compound chicken vitamin, 0.08-0.15 part of compound chicken ore, 0.12-0.15 part of choline, 0.03-0.05 part of complex enzyme preparation, 0.08-0.12 part of composite microecologics and 0.03-0.04 part of 15% bacitracin zinc. The digestibility of the breeding feed can be greatly improved, the palatability of the feed is improved, the immunity and disease resistance of the yellow feather broilers are enhanced, and the morbidity of yellow feather broilers is lowered, so that the survival rate of the yellow feather broilers is improved, and the hatchability of the yellow feather broilers is ensured.

Description

technical field [0001] The invention relates to the field of animal husbandry, in particular to a breeding method for improving the hatchability of yellow-feathered broiler chickens. Background technique [0002] Yellow feather broilers are divided into three categories: fast large, high-quality and green-legged. The fast and large-scale yellow chicken has the characteristics of yellow chicken, yellow feathers, black feathers on the neck, wings, and tail, and the feathers grow fast. Its feet are ephedra or yellow in feathers, and its feet are blue. It grows at a medium speed and has excellent meat flavor. It is a typical imitation soil breed chicken strain. As different regions and different markets have different consumption demands for yellow-feather broiler chickens, people pay more and more attention to the breeding of yellow-feather broiler chickens. [0003] Nowadays, the breeding of yellow feather broilers must be guaranteed. During the breeding process of yellow fe...

Problems solved by technology

[0003] Nowadays, the breeding of yellow feather broilers must be guaranteed. During the breeding process of yellow feather broilers, it is necessary to ensure the egg production of yellow feather broilers and the hatching rate of eggs, and to ensure the hatching rate of yellow feather broilers, it is necessary to use high Nutritious breeding feed to increase the weight and survival rate of yellow-feather broiler chickens, thereby increasing the egg production of yellow-feather broiler chickens, ensuring that the eggs of yellow-feather broiler chickens are of uniform size, and there are no deformed eggs, which in turn facilitates the hatching of yellow-feather broiler chickens However, there is a lack of breeding feed and methods that can improve the hatchability of yellow feather broilers on the market
