摘要
对舍饲和放牧条件下,滩羊母羊和羔羊生产性能进行了研究。结果显示:舍饲条件下滩羊母羊的繁殖率和繁殖成活率比放牧条件下有一定程度提高。羔羊的初生重、二毛期体重、平均日增重及肩部毛股弯曲数则有明显地提高,经t检验舍饲与放牧之间均呈极显著差异(P<0.01)。而羔羊成活率、肩部毛股长度和花穗评分等指标二者之间无明显区别,经t检验差异均不显著(P>0.05)。说明舍饲在提高滩羊生产性能方面具有一定作用,同时对其品种特征无不良影响。
<Abstrcat> The research is on the performance of Tan sheep under the conditions of indoor and grazing production system. The result shows that the reproductive rate and reproductive efficiency of the ewes have increased in the condition of indoor feeding in comparison with those in the condition of grazing(P<0.01). The birth weight, the weight of a 35-day lamb and its daily gain also have increased a lot, as well as its shoulder wool crimps (P<0.01). The lamb's survival percent, the length of its shoulder wool and its fur score are almost the same under the two different feeding conditions (P>0.05). So indoor feeding is an efficient feeding method for Tan sheep. It can increase Tan sheep's production performance and maintain the character of the lamb fur.\;
