查询词典 piglets

Selection for increased number of piglets born has been employed in pigs with only limited success because of the low heritability, the late expression in life and the sex-limited nature of reproductive traits. And so, the genetic progress of reproductive traits only depended on crossbreeding in the past years.

传统的数量遗传学在指导家畜育种中起到了重要的作用，但是繁殖性状遗传力低、性状表现晚、而且是限性遗传，通过常规选择难以有所进展。

Reproduction is a key process, which highly influences the economic efficiency of pig production. Traditional quantitative genetics plays a very important role in animal breeding. Selection for increased number of piglets born has been employed in pigs with only limited success because of the low heritability, the late expression in life and the sex-limited nature of reproductive traits.
