固态发酵复方中药防治奶牛乳房炎的效果及对生产性能的影响

摘要

本研究采用枯草芽胞杆菌和产朊假丝酵母按等比例制作固态发酵复方中药,并对复方中药发酵前后对奶牛乳房炎及生产性能的影响进行了对比分析.结果表明,与空白组相比,复方中药发酵前后均可显著降低奶牛乳房炎的发病率(P＜0.05),可提高牛奶的乳蛋白率(P＞0.05)和乳脂率(P＞0.05),可显著提高奶牛产奶量(P＜0.05),添加复方中药制剂组和发酵的复方中药制剂组的产奶量分别较空白组提高了0.72kg/d和2.64kg/d;经发酵后的复方中药制剂在降低奶牛乳房炎发病率、改善乳品质和增加产奶量等方面的效果均优于未发酵的复方中药制剂(即普通中药制剂);复方中药经发酵后,有利于提高中药的利用率及药理活性.%The production technique of compound Chinese herbal medicines by Bacillus subtilis and Candida utilis solid fermentation was investigated.Furthermore,the effects of fermented and unfermented compound herbal medicines on mastitis and the performance of dairy cows were contrastively analyzed.The results indicated that the fermented and unfermented compound herbal medicines could reduced the incidence of mastitis (P＜0.05),improved the milk protein percentage (P＞0.05) and milk butter-fat percentage (P＞0.05),and increased the average milk yield prominently (P＜0.05).The average milk yield of unfermented and fermented compound herbal medicines treatment increased 0.88kg/d and 2.71kg/d more than that of the blank treatment,respectively.What's more,the effects of fermented compound herbal medicines on the mastitis incidence,the milk quality and the milk yield were superior to that of unfermented compound herbal medicines.It showed that their bioavailability and pharmacological activities were improved after compound Chinese herbal medicines were fermented by Bacillus subtilis and Candida utilis with same.
