摘要
该研究旨在初步了解无角陶赛特羊和特克塞尔羊对甘肃榆中地区的适应性,以便为该地区引进推广良种肉羊提供依据。以兰州奉特动物科技有限公司榆中肉羊繁育中心的无角陶赛特羊和特克塞尔羊为研究对象,对其2016—2018年的繁殖性能进行了分析,同时对2018年无角陶赛特羔羊和特克塞尔羔羊从出生到2月龄(断奶)的生长发育性能进行了测定。结果表明:从2016年到2018年无角陶赛特羊、特克塞尔羊的繁殖率、产羔率、双羔率均在逐年提高;特克塞尔羔羊初生重、1月龄重以及2月龄重均高于无角陶赛特羔羊,但差异均不显著(P>0.05);特克塞尔羔羊1月龄胸宽、2月龄胸宽和体长均显著高于无角陶赛特羔羊(P<0.05),其他体尺指标差异均不显著(P>0.05)。说明两个肉羊品种在甘肃榆中地区均有良好的繁殖性能以及较高的生长性能,均可在榆中及其周边地区推广养殖。
In order to provide the basis for introducing and popularizing the good breed of mutton sheep in Yuzhong county of Gansu province,the adaptability of Poll Dorset sheep and Texel sheep to the environment was researched.Poll Dorset sheep and Texel sheep at sheep breeding center of Lanzhou Fengte Animal Science and Technology Co.,Ltd.were used the object of study.The data of reproductive performance were analyzed from 2016 to 2018,in addition,the growth traits of Poll Dorset lambs and Texel lambs from birth to 2 months of age(weaning)were measured in 2018.The results showed that reproduction rate,lambing rate and twin rate of Poll Dorset sheep and Texel sheep increased gradually from 2016 to 2018.The body weight of Texel sheep at birth,1 month and 2 months old was more than that of the Poll Dorset sheep,but the difference was not significant(P >0.05).The chest width and body length of Texel sheep at the age of 1 month and 2 months were significantly higher than those of the Poll Dorset lamb(P<0.05),and no significant difference in other body size indexes(P >0.05).Therefore,the reproductive performance and growth performance of Poll Dorset sheep and Texel sheep were good in Yuzhong county of Gansu province,these sheep could be raised and popularized in this region.
