Cultivation method for speckle feather, meat and egg multi-purpose type duck with high reproductive rate

Abstract

The invention provides a cultivation method for speckle feather, meat and egg multi-purpose type duck with high reproductive rate. The method comprises the following steps: taking Shanma duck pure line as a female parent and Jianchang duck shallow speckle feather male duck as a male parent and then hybridizing for the first time; taking the male duck acquired after the hybridizing for the first time as the male parent and the female duck of Shanma duck pure line as the female parent and then hybridizing for the second time; taking the female duck obtained after the hybridizing for the second time as the female parent and the male duck of large-body type cherry valley duck maternal line as male parent and then hybridizing for the third time; taking the female duck obtained after the hybridizing for the third time as the female parent and the male duck of large-body type cherry valley duck maternal line as the male parent and then hybridizing, thereby obtaining the fourth generation of hybridized group; lastly, performing transverse fixing and systematic breeding, thereby obtaining a new strain of the speckle feather meat duck with high reproductive rate, more eggs, excellent meat performance and phenotype stability. The feather of the whole body of the speckle feather meat duck obtained according to the method provided by the invention is primary in yellow speckle color; the thorax and abdomen parts are locally marked with white feather; the weight of the adult duck is 2.75kg-3.00kg; the marketing weight of the 8-week old commodity meat duck can reach up to 1.95kg-2.25kg; the annual egg yield of the female duck can reach up to 250; the fertility rate of the hatching egg is above 94%.

Description

technical field [0001] The invention relates to the technical field of poultry breed selection and breeding, in particular to a breeding method for ducks with stable production phenotype, excellent meat and egg production performance and high reproduction rate. 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 ...

AI Technical Summary

Problems solved by technology

The hemp-feather duck breeds, such as Shanma duck, Shaoxing duck, Jinding duck, etc., can produce about 300 eggs per year, but they are small in size, with an adult weight of only about 1.5kg, slow growth in the early stage, and poor meat performance.

If the dual-purpose hemp-feathered meat duck or the fast large white-feathered meat duck male is used as the male parent of the hybrid, and the female duck of the laying duck breed is used as the female parent of the hybrid, on the one hand, the size difference between the male and female ducks is large, which affects the fertilization rate of eggs; , the offspring of this simple and random hybridization have serious feather color separation and uneven growth speed, which seriously affects the breeding benefits of farmers and the sales of commercial meat ducks

[0004] At present, there are still problems in the crossbreeding research on the use of fast large meat ducks and small laying ducks, which only focus on meat quality and feed remuneration, such as "Crossing Effects of Cherry Valley Ducks and Jianchang Ducks", "Cherry Valley Meat Ducks and 2 Comparative Analysis of Hybridization Effects of Egg Duck Breeds", this research direction cannot solve the above-mentioned problems urgently needed by the industry.
