Problems solved by technology

[0005] The feed conversion ratio of Lingnan Yellow Chicken No. 2 independently bred by the Institute of Animal Science (Institute of Animal Husbandry) of the Guangdong Academy of Agricultural Sciences has reached 1.8:1. It is lower than Wannan Sanhuang chicken, so how to improve and breed a new generation of broiler chickens with high feed conversion rate and large body size based on Wannan Sanhuang chicken, a high-quality broiler breed, is an important research direction now

Abstract

The invention provides a yellow-feather broiler breeding method with high feed conversion rate, and relates to the technical field of yellow-feather broiler breeding. The yellow-feather broiler breeding method with the high feed conversion rate mainly comprises the steps that southern Anhui Sanhuang chickens are adopted as progenitor female parents to be hybridized with Lingnan yellow chickens and Huainan spotted-brown chickens respectively, then offsprings are hybridized, and then the final filial offspring is hybridized with male Anhui Sanhuang chickens to obtain commercial generations. The defects in the prior art are overcome, the overall weight of the slaughtered broilers is increased on the basis that the meat quality of the broilers is guaranteed, the feed conversion rate in the breeding process is effectively increased, and the feeding cost is reduced.

Description

technical field [0001] The invention relates to the technical field of yellow-feather broiler breeding, in particular to a yellow-feather broiler breeding method with high feed conversion rate. Background technique [0002] Wannan Sanhuang Chicken (also known as Wannan Native Chicken) is an excellent local breed of both egg and meat in Anhui Province. It is mainly distributed in Qingyang County, Chizhou, Xuancheng and other places along the Yangtze River in our province. Known for its tender and delicious meat. This breed has a traditional breeding base in our province and was once the leading breed in the local chicken market. [0003] Due to the slow growth rate of Wannan Sanhuang chicken in the early stage, it can be slaughtered when it is fully mature in 60 weeks, but generally this chicken grows most rapidly at 8-12 weeks, and the subsequent and early growth rates are slower. The conversion rate of feed during the breeding process is relatively high. low, affecting th...
