中药复方对山羊的影响:Ⅳ·瘤胃内环境参数

Effect of Chinese Medicine Prescription on the Goat:Ⅳ.The Internal Environment Parameters of Rumen

试验旨在研究中药复方对山羊瘤胃内环境参数的影响。选择6头健康的体重相近的安装有永久性瘤胃瘘管的周岁大足黑山羊羯羊,按3×3重复拉丁方试验设计。对照组饲喂基础日粮,2个处理组分别在基础日粮上给每头羊日喂15 g复方Ⅰ和复方Ⅱ(由藿香、苍术、黄柏和生石膏等中药按不同比例组成)。结果表明:2种复方对山羊瘤胃pH及氨氮浓度均无显著影响(P>0.05);复方Ⅰ能极显著提高山羊瘤胃内丁酸浓度及丁酸占总挥发性脂肪酸的比例(P<0.01),显著提高山羊瘤胃内乙酸和总挥发性脂肪酸等浓度(P<0.05),而复方Ⅱ仅能显著提高山羊瘤胃内丁酸浓度(P<0.05)。结果提示,2种复方均能改善山羊瘤胃内环境状况,且复方Ⅰ作用效果优于复方Ⅱ。

The aim of the study was to investigate the effects of Chinese medicine prescription on the internal environment parameters of rumen for the goat. Six healthy Dazu black wether, with permanently ruminal cannula, which had one year age and the similar body weight were randomly allotted into three groups by a 3 x3 double Latin square design. The goats in the control group were fed the basal diet. And the goats in the two treatment groups were fed the basal diets with different Chinese medicine prescriptions 15 g per day per goat, such as prescription I and prescription Ⅱ , which composed of Herba Agastachis, Rhizoma Atractylodis, Cortex Phellodendri and Gypsum Fibrosunm with different proportions, respectively. The results showed that every prescription could not influence the ruminal pH and ammonia N concentration significantly; the prescription I could increase the butyrate concentration and the concentration ratio of butyrate to total volatile fatty acids at a highly significant level （P〈0.01） and increase the concentrations of acetate and total volatile fatty acids at a significant level （P〈0. 05） in the rumen of goats; the prescription Ⅱ could increase the butyrate concentration at a significant level （P〈0. 05） in the rumen of goats. The results could suggest that every prescription could improve the internal environment of rumen and the action effect of the prescription I was better than that of the prescription Ⅱ.
