摘要
以滩羊为试验动物,采用30 d、45 d、60 d断奶,4月龄断奶为对照。研究结果表明,羔羊的早期断奶有利于母羊产后和断奶后体况的恢复和母羊发情期的提前到来,以30 d断奶母羊体况恢复最佳和对提前母羊的发情期效果最好。
Tan sheep was the experimental objects. The lambs were weaned at 30, 45 and 60 days old, 4-month old was used as the control. The results indicated early weaning can help renew the body condition of ewes and bring forward the estrus,and weaning at 30 days is the best for both.
