| Abstract: | The objective of this study was to investigate the effects of different levels of medicinal plant extracts on feed intake,feeding behavior,nutrient digestion and rumen fermentation performance of sheep.Sixty sheep with an average body weight of 82.76 kg were randomly divided into 3 groups with 5 replicates per group and 4 sheep per replicate.Sheep in the three groups were fed basal diet+0,80 and 160 mg/kg compound plant extract,respectively,during the 10 W trial period.Results:Compared with control group,the average daily gain of sheep in 80 mg/kg plant extract group was significantly increased by 14.58%(P<0.05),while the feed/gain of sheep in 80 and 160 mg/kg plant extract groups was significantly decreased by 13.34%and 6.64%(P<0.05),respectively.Compared with the control group,the feeding time in 80 and 160 mg/kg plant extract groups was significantly increased by 13.84%and 11.05%(P<0.05),but the standing time was significantly decreased by 11.87%and 10.46%(P<0.05),respectively.Compared with the control group,the drinking water and lying time of sheep in 80 mg/kg plant extract group were significantly increased by 22.86%and 31.77%(P<0.05).Compared with the control group,the rumen volatile fatty acid concentration in 80 and 160 mg/kg plant extract groups was significantly increased by 6.45%and 5.41%(P<0.05),and the rumen butyric acid concentration in 80 mg/kg plant extract group was significantly increased by 4.48%(P<0.05),respectively.Conclusion:Under the conditions of this experiment,adding plant extracts in the diet can improve the feeding behavior of sheep and increase the concentration of volatile fatty acids in the rumen.Considering the daily gain,feed efficiency and fiber digestibility,the appropriate concentration of plant extracts in the diet is 80 mg/kg. |
