畜禽饲料效率性状遗传研究进展
Progress in Genetic Studies of Feed Efficiency Traits in Livestock and Poultry
摘要
Abstract
Feed efficiency is an important indicator for evaluating the efficiency of livestock production,and it is one of the important traits in livestock and poultry breeding research.In the past few decades,livestock and poultry production traits such as meat,egg and milk yields have made significant genetic progress.With the increase of feed cost year by year,feed efficiency trait has gradually received high attention from breeders in recent years.European and American countries have successively included feed efficiency as a breeding target in the comprehensive selection index,and China has also begun related research and recieved research progress.This paper introduces the concept of feed efficiency,commonly used indicators,statistical analysis models and their genetic parameter estimation,and summarizes the research progress of common livestock and poultry feed efficiency traits at home and abroad,in order to further analyze the genetic mechanism of livestock and poultry feed efficiency traits and optimize the breeding program to provide reference.关键词
