Hybridization complement technique for making ducks lay eggs with greenish shell

Abstract

The hybridization matching technique of green case egg breeded by the duck, is a breeding seed selection technique of poultry high quality species. The species is the high oil duck, people centralize the individual and do group feeding to breed. Detect the genetype of the male duck in the group, the determination is letting the male duck and the female duck which breed white case egg cross, if the descendants all breed green case eggs, the male duck is the green case gene homozygous type; if the descendants breed green and white case eggs, the male duck is the gene heterozygous type; If the descendants all breed white case eggs, the male duck is the white case gene homozygous type. Select the green case gene homozygous male ducks to match with the female ducks which breed green case eggs, we will get the green case homozygous group. Take it as the paternal after the selection of performance, then match with other groups, the descendants will all be the ducks that breed green case eggs. The invention adopts quality description genetic principle to improve the breed and quality of the duck, it is simple, scientific, advanced, and with great spread application value.

Description

technical field

[0001] The invention relates to the breeding technology of high-quality poultry varieties, in particular to the matching technology of hybridization of green shell eggs produced by ducks in poultry production. Background technique

[0002] The eggshell color of duck eggs is divided into white shell and blue shell. Good shell quality has a very important impact on the transportation and storage of eggs. Scientific experiments have proved that the eggshell quality of green-shelled eggs is better than that of white-shelled eggs. At the same time, due to the influence of consumers' traditional culture, green-shelled eggs are very popular among consumers, and the market price is high. Product sales and feeding benefits have been significantly improved.

[0003] Gaoyou Duck is a well-known local duck breed with both eggs and meat. It is famous both at home and abroad for its high-quality eggs and double-yolk eggs. The annual sales volume of Gaoyou duck eggs and ...
