猪饲料利用效率性状的遗传解析策略及研究进展
Genetic Analysis Strategies and Research Progress of Feed Utilization Efficiency Traits in Pigs
摘要
Abstract
High feed cost(accounting for 60%～80%of the total cost of pig breeding)has become a key bottleneck restricting the improvement of pig breeding industry in China.Deciphering the molecular mechanisms formed from pig feed utilization efficiency and improving the feed utilization efficiency of pig is a crucial way to reduce pig breeding cost.With the development of sequencing technology and the research&application of intelligent equipment,it is convenient to obtain phenotypic data and omics data of pig feeding and growth performance.Researchers have identified numerous candidate functional genes and molecular markers that affect pig feed efficiency through strategies such as integrating genome,transcriptome and proteome,and applied them in breeding practice,which has accelerated the progress of genetic improvement of feed utilization efficiency traits in breeding practice.In the paper,the genetic analysis strategy,genetic improvement strategy of pig feed utilization efficiency traits and the breeding process of grain-saving breeding pigs in China were summarized,with the aim of providing reference for pig breeding industry to reduce costs and increase efficiency,promoting the cultivation of new breeds(lines)of grain-saving breeding pigs.关键词
