杂谈猪的遗传改良——辩证对待氟烷敏感基因
By-talks about Pig Genetic Improvement: Treat Halothane Gene Dialectically
摘要
Abstract
Halothane gene (Haln) is one of major genes affecting pork quality,and the recessive homozygous genotype (nn)can result in stress reaction,such as PSE and PSS.Thus,the process to remove this gene from each breed began in China since it was confirmed.However,the Haln gene still exists and the gene frequency is very high in the Pietrain population which suggested us to treat the gene dialectically.In fact,a lot of research shows heterozygous individuals (HalNn) perform better than dominant homozygous individuals (HalNN) in average daily gain,dressing percentage,lean percentage,etc.,and have no significant differences in meat quality except Water Holding Capacity.From this viewpoint,we will benefit from the following measures:(1) using Halnn males (eg.Pietrain) as terminal boars,and HalNN females (eg.Landrance×Yorkshire) as parental sows to produce HalNn commercial pigs.(2) administrating the Halnn boars more carefully and applying artificial insemination.For the reason above,it is recommended to study Haln further.关键词
