Abstract

A method for selectively culturing the layer duck features that according to the regression relation between 7 biochemical genetic marker indexes of duck's blood (including serum thyroxin T4, 3, 5, 3'-triiodothyronine T3, IGF, BP, TP, GOT, and GPT), and the egg characters (including egg productivity, total egg weight and average egg weight), 5 of said indexes are chosen to create a regression equation, and the selective culture is then performed.

Description

technical field

[0001] The invention relates to a poultry breeding technology, in particular to a breeding duck breeding technology. technical background

[0002] Poultry breeding is a work of great investment, long time, high difficulty and great significance, especially the breeding of laying ducks. The traditional selection work is mainly based on the descendant determination method. According to the various traits of the age of ducks, after predicting the various production performance traits of their offspring, the laying ducks are selected and bred. Therefore, there is: the first workload is extremely huge, and it is usually necessary to carry out daily monitoring of the 500-day growth period of the designated laying ducks. The determination of production traits requires a lot of labor; second, the determination of descendants requires a large number of eliminations, which leads to huge economic losses, and requires a large number of breeding...
