摘要
试验旨在探究产前饲喂复方中草药制剂对湖羊流产率和产羔率的影响。选取妊娠后期母羊2100只,随机分为2组,试验组1100只,设11个重复,每个重复100只羊;对照组1000只,设10个重复,每个重复100只羊。对照组羊饲喂基础日粮,试验组羊饲喂添加5 mL/只复方中草药制剂的试验日粮。试验期10 d。结果显示:与对照组相比,试验组羊的流产率显著降低(P<0.05);试验组羊产弱羔率、瘫羊率显著降低(P<0.05);试验组羔羊死亡率显著降低(P<0.05),治愈率显著提高(P<0.05)。与对照组相比,试验组单胎重、双胎重、三胎重显著提高(P<0.05)。研究表明,饲粮中添加复方中草药制剂5 mL/只能够改善妊娠母羊流产数、弱羊数、瘫羊数和提高产羔率及羔羊治愈率。
The experiment was to explore the effect of prenatal feeding of compound Chinese herbal medicine preparation on the abortion rate and lambing rate of Hu sheep.A total of 2100 ewes in late pregnancy were selected and randomly divided into two groups.Test group consisted of 1100 ewes with 11 replicates,100 sheep in each replicate.Control group was consisted of 1000 ewes with 10 replicates and 100 sheep in each replicate.The sheep in control group were fed with basic feed,and sheep in test group were fed with test feed supplemented with 5 m L/head compound Chinese herbal medicine preparation for 10 d.The results showed that compared the control group,the abortion rate in test group was significantly reduced(P<0.05).Compared with control group,the weak lambing rate and paralyzed sheep rate in test group were significantly reduced(P<0.05).Compared with control group,the lamb mortality of test group was significantly reduced(P<0.05),and the cure rate was significantly increased(P<0.05).Compared with control group,the single tire weight,twin weight and triple tire weight were significantly increased(P<0.05).The study indicates that the addition of5 mL/head compound Chinese herbal medicine preparation to feed can improve the number of abortions,weak sheep and paralyzed sheep of pregnant ewes,and increase the lambing rate and the cure rate of lambs.
