Method for cultivating medium-speed high-quality spotted-brown chickens suitable for slaughtering and living body marketing

Abstract

The invention relates to a method for cultivating medium-speed high-quality spotted-brown chickens suitable for slaughtering and living body marketing. The method comprises the following steps: takingslow-feathering, yellow-shank, yellow-skin and recessive white-feathering chickens (B line) as a first female parent; and taking fast-feathering, yellow-shank, yellow-skin, spotted-brown-feathering and big-cockscomb chickens (C line) as a first male parent. According to the genetic principle of fast and slow feathering self-sexing, a parent generation (BC line) is produced by crossing a B line and a C line to serve as a terminal female parent, parent generation chicks can self-sexing through fast and slow feathering, hens are fast-feathering chickens, and cocks are slow-feathering chickens. The commercial generation (ABC) is produced by using fast-feathering, yellow-shank, yellow-skin, large-cockscomb and spotted-brown-feather fast large line (A line) as a terminal male parent and three line mating hybridization of male A line X (male B line X female C line) female, commercial generation cocks have the characteristics of fast feathering, yellow shank, yellow skin, sexual precocity, large cockscomb, wide chest and the like. The commercial generation is marketed when at the age of 90-95 days, the carcass is beautiful, the feather color is bright, the cockscomb is large, the meat production performance is good, the meat quality is good, the carcass packaging property of high-quality chickens and the packaging property of living body marketing are obviously identified, and the marketing standard of medium-speed slaughtered high-quality chickens and live chickens is met.

Description

technical field

[0001] The invention relates to a method for cultivating medium-speed and high-quality jute chickens suitable for slaughter and live marketing, and belongs to the field of poultry genetics and breeding. Background technique

[0002] In recent years, the poultry industry has been repeatedly affected by sudden bird flu incidents, causing heavy losses to the industry. What's more, it has hit the consumption of chicken products, which has had a serious negative impact on the market capacity of my country's broiler industry. From 2015 to 2017, my country's yellow feather broiler production efficiency has declined for three consecutive years, and the industry has entered an important period of change. In this context, the Ministry of Agriculture put forward the 16-character policy of "scale breeding, centralized slaughtering, cold chain distribution, and chilled fresh market" to promote the transformation and upgrading of the poultry industry. However, due to Chin...
