油莎豆粕和中药复合发酵物对小尾寒羊生长性能、养分消化率、抗氧化、免疫功能和精液质量的影响

Effects of fermented composite preparations of Cyperus esculentus meal and traditional Chinese medicine on growth performance,nutrient digestibility,antioxidant capacity,immune function and semen quality of smalltailed han sheep

试验旨在研究饲粮中添加油莎豆粕和中药复合发酵物、油莎豆粕和发酵油莎豆粕对小尾寒羊生长性能、养分表观消化率、血清抗氧化和免疫性能、精液质量等指标的影响。将72只日龄相近,体重相近的健康公羊随机分成4组,分别为3个试验组和1个对照组,对照组饲喂基础饲粮,试验组分别在基础饲粮中添加1%油莎豆粕和中药复合发酵物(1%FCEMH)、3%油莎豆粕(3%CEM)和3%发酵油莎豆粕(3%FCEM),每组3个重复,每个重复6只羊,试验期为70 d,其中预试验期5 d,正式试验期65 d。结果表明,试验组羊末重显著高于对照组(P<0.05),1%FCEMH组平均日增重显著提高,料重比显著降低(P<0.05);1%FCEMH组干物质、粗蛋白、中性洗涤纤维消化率显著提高(P<0.05);1%FCEMH组羊血清IgM含量显著提高(P<0.05),血清中丙二醛数量呈下降趋势;1%FCEMH组具有提高羊精液量、精子顶体完整率和精浆中睾酮含量,降低精子畸形率的趋势。在羊饲粮中添加油莎豆粕和中药复合发酵物,可提高公羊增重、养分消化和降低料重比,并在一定程度上有利于抗氧化、免疫性能和精液质量提高。

This experiment was conducted to investigate the effects of fermented composite preparations of Cyperus esculentus meal and traditional Chinese medicine(FCEMH),Cyperus esculentus meal(CEM),and fermented Cyperus esculentus meal(FCEM)on growth performance,nutrient apparent digestibility,serum antioxidant and various biochemical indicators,semen quality and other indicators of small-tailed han sheep.Seventy-two healthy male sheep with similar age and weight were randomly divided into four groups,namely three experimental groups and one control group.The control group was fed with a basic diet,and the experimental group fed with the diet added 1%FCEMH(1%FCEMH),3%CEM(3%CEM)and 3%FCEM(3%FCEM),respectively.Each group had three replicates,with six sheep per replicate.The experimental period was 70 days,with a pre-experimental period of 5 days and a formal experimental period of 65 days.The results showed that compared with the control group,all the experimental groups significantly increased the final body weight(P<0.05).The 1%FCEMH group could effectively increase the average daily weight gain of sheep and reduce the feed to weight ratio(P<0.05).The 1%FCEMH group significantly increased the digestibility of dry matter,crude protein,and neutral detergent fiber in sheep(P<0.05).The serum IgM content of sheep in the 1%FCEMH group significantly increased(P<0.05),and the serum malondialdehyde showed a certain downward trend.The 1%FCEMH group showed a trend of increasing sheep semen volume,acrosomal integrity rate in semen and testosterone content in seminal plasma,and reducing sperm malformation rate.Adding fermented composite preparations of Cyperus esculentus meal and traditional Chinese medicine to sheep feed could improve weight gain,nutrient digestion,and reduce F/G,and to some extent,it was beneficial for improving antioxidant capacity,immune performance,and semen quality.
