A kind of seed production method of light hemp feather meat duck

Abstract

The invention discloses a light-speckle feather meat duck breeding method. A Jianchang speckle feather system ducks, mountain speckle ducks and SM3 system cherry valley ducks are used as a genetic material; a large-body shallow-speckle feather meat duck new variety is obtained through cross breeding, selective breeding and family breeding, based on the advantages of excellent meat quality of the Jianchang speckle feather system ducks, large number of eggs of the mountain speckle ducks, and fast growth of the SM3 system cherry valley ducks. The breeding method obtains the large-body shallow-speckle feather meat duck new variety through breeding means including pure breeding, cross breeding, feather color selective breeding, and family breeding, wherein the large-body shallow-speckle feather meat duck new variety is consistent in appearance, is beautiful in carcass, and is stable in production performance; and the breeding method can remarkably promote large-scale and modernization development of a speckle feather meat duck industry.

Description

technical field [0001] The invention belongs to the field of poultry seed production, and in particular relates to a seed production method of light flake-feathered meat duck. Background technique [0002] my country is a big meat duck producing country. In recent years, the annual meat duck production in my country has always been more than 70% of the world's total. In the northern part of my country, meat duck farming is mainly based on large white-feathered meat ducks, which are produced in the form of intensive breeding and large-scale slaughtering and processing. In most of the traditional waterfowl production areas in southern my country, consumers generally like the local duck species with flax feather. Traditional salted duck, stewed duck, camphor duck, sweet duck and other duck products are also produced with flax duck as raw materials. It is generally believed that compared with fast and large white-feather ducks, hemp-feather ducks have better quality, and their ...

AI Technical Summary

Problems solved by technology

However, this breeding method has the following disadvantages: 1) Jianchang duck is a local breed with better meat performance in my country's hemp-feathered meat duck, but its duckling feather color is four-point flower, and the adult duck feather color is divided into deep hemp, light There are many types of hemp ducks, white-breasted black ducks, etc., the feather color separation is serious, and the egg production of Jianchang duck female ducks is low. The annual egg production of a single female duck is only about 150, which cannot meet the large-scale production of hemp feather meat duck industry. need

2) Using Jianchang duck and other four-spotted shelducks as parents to carry out crossbreeding for the production of commercial shelducks, there are problems such as more serious feather color separation and uneven growth speed

3) Regardless of whether local breeds are used for direct production or hybrid production, there are problems of small size, slow growth, high production cost, poor uniformity, and unsuitability for large-scale breeding and slaughtering of commercial meat ducks.
