Abstract: | The rabbit is a kind of grain-saving and small herbivore animal.Rabbit breeding which is low investment and obvious efficiency has become an advantageous industry of increasing income of rural farmers and poverty alleviation.In recent years,with the development of life science,great progress has been made in rabbit genetic breeding at home and abroad.In this paper,the research progress in genetic breeding and reproduction of rabbits in 2019 are reviewed from the traditional breeding,molecular breeding and reproduction of rabbits.For abroad,lots of researches involved in traditional breeding,molecular breeding and reproduction were done.Effects of selection,environment and additives on productive performance had been analyzed in traditional breeding.Molecular breeding mainly focused on reproductive performance among which there were more studies on litter size and spermatine.Secondly,the related genes of growth,meat quality and hair color were studied.The research on reproduction mainly focuses on the preservation method of male rabbit semen and the effects of additives on rabbit semen quality,litter size and conception rate.In China,genetic breeding and reproduction research on rabbit also mainly included traditional breeding,molecular breeding and reproduction,but the focus of domestic research was molecular breeding,among which breed and genetic diversity and functional genes of fur trait were mainly researched using high-throughput sequencing,gene cloning and gene editing to screen the important functional genes and regulatory networks related to research traits.However,compared with molecular breeding,there are fewer studies on the traits evaluation of traditional breeding and rabbit reproduction.This review can provide references for rabbit breeding and production. |
