摘要
文章结合湖羊繁殖工作中母羊妊娠鉴定重要环节,引进英国 BCF 生产的 Ovi-Scan 便携式兽用多胎B超,辅助繁殖人员及时准确快速检查配种母羊怀孕状况,通过对 406 只成年母羊、223 只青年母羊、184 只复配母羊进行多胎 B 超妊娠检查,B 超孕检受胎率分别达到 80.05%、82.96%和 69.56%,准确度平均达到99.34%;母羊怀孕 3 羔及以上多胎B超妊娠检查准确度达到 95.39%;3 羔及以上母羊分娩 152 只,产羔 463 只,羔羊平均初生重 3.27 kg,同比提高 4.81%.通过多胎 B超使用,显著提高母羊孕检揭发率,并对检出空怀母羊及时配种,同时对检出怀孕 3 羔及以上母羊分群饲养,有效提高羔羊初生重,提高湖羊母羊繁殖效率.
Abstract
In this paper,based on the important link of ewe pregnancy identification in Hu sheep breeding,Ovi-Scan portable veterinary multi-fetal B-ultrasound produced by British BCF was introduced to assist breeders in timely,accurate and rapid detection of the pregnancy status of breeding ewes.Through the multi-fetal B-ultrasound pregnancy examination of 406 adult ewes,223 young ewes and 184 mixed ewes,the pregnancy rate was 80.05%,82.96%and 69.56%,respectively,and the average accuracy was 99.34%.The accuracy of B-ultrasound in pregnancy examination of ewes with 3 lambs or more was 95.39%.A total of 152 ewes with 3 lambs and above gave birth,and 463 lambs were born.The average birth weight of lambs was 3.27 kg,which was 4.81%higher than that of last year.Through the use of multi-fetal B-ultrasound,the detection rate of pregnancy of ewes was significantly improved,and the pregnant ewes were timely mated,and the pregnant ewes with 3 lambs or more were fed in separate groups,which effectively increased the birth weight of lambs and improved the breeding efficiency of Hu-sheep ewes.
