非洲猪瘟时期对猪育种工作的影响及发展措施

Influence of African Swine Fever Period on Pig Breeding and Development Measures

2018年下半年,非洲猪瘟疫情在全国范围内快速传播蔓延,对我国生猪养殖业造成严重威胁,大量生猪被扑杀,生猪存栏量显著下降,猪肉价格显著升高,影响人们的正常生产生活和消费。非洲猪瘟爆发流行大背景下,对我国猪育种工作造成重创,全国能繁母猪的数量大幅度锐减,种猪的供应能力不足,要生猪恢复生产能力,需保证充足的能繁母猪数量。为确保繁殖母猪的数量,在很多养殖场都会选择使用三元杂交猪用于繁殖,但是由于三元母猪的发情、产仔、泌乳、带仔能力、使用寿命都存在一定问题,对种猪的繁育产生很大影响。该文主要论述非洲猪瘟时期对湖南祁东县猪繁育工作产生的影响。
