摘要
[目的]为探究微生态制剂对奶牛瘤胃酸中毒的治疗效果。[方法]选用40头泌乳奶牛,随机分为4组,对照组奶牛饲喂基础日粮,试验Ⅰ组、Ⅱ组和Ⅲ组分别饲喂基础日粮+1%、2%和3%的复合微生态制剂,试验周期为预试期7天,正式试验期30天。通过检测奶牛生长性能指标、泌乳性能指标和瘤胃发酵参数。[结果]与对照组相比,试验Ⅰ组、Ⅱ组和Ⅲ组的平均日增重、平均日采食量显著提高(P<0.05),料重比显著降低(P<0.05),产奶量及牛奶中的乳脂率显著升高(P<0.05);奶牛瘤胃液pH和乳酸含量显著降低(P<0.05),试验Ⅰ组、Ⅱ组和Ⅲ组乙酸、丙酸和丁酸含量显著升高(P<0.05),乙酸/丙酸比值显著降低(P<0.05)。[结论]奶牛基础日粮中混饲微生态制剂可以提高生长性能和泌乳性能,改善瘤胃发酵参数,治疗瘤胃酸中毒。
[Objective]To explore the therapeutic effect of microecological preparation on rumen acidosis in dairy cows. [Method]Forty lactating cows were randomly divided into four groups. The control group cows were fed with the basic diet. Group Ⅰ,Group Ⅱ and Group Ⅲ were fed with the basic diet plus 1%,2% and 3% compound microecological agents respectively. The test period was 7 days in the pre test period and 30 days in the formal test period. The growth performance,lactation performance and rumen fermentation parameters of dairy cows were measured. [Result]Compared with the control group,the average daily weight gain and average daily food intake of group I,group Ⅱ and group Ⅲ were significantly increased(P <0.05),the feed to weight ratio was significantly decreased(P<0.05),and the milk yield and the percentage of milk fat in milk were significantly increased(P <0.05).The pH and lactic acid content in rumen fluid of dairy cows decreased significantly(P <0.05), the content of acetic acid, propionic acid and butyric acid in test groups I, Ⅱ and Ⅲ increased significantly(P<0.05),and the ratio of acetic acid to propionic acid decreased significantly(P<0.05).[Conclusion] Mixed microecological preparation in basic diet of dairy cows can improve growth performance and lactation performance,improve rumen fermentation parameters, and treat rumen acidosis.
