摘要
本研究以不同牧场中的荷斯坦奶牛为研究对象,以100~200g/(头·d)的剂量添加干酪乳杆菌HM-09和植物乳杆菌HM-10及其代谢产物的复合乳酸菌微生态制剂(有效活菌数≥1.5×109 cfu/g),应用牛场DHI数据中的乳体细胞数(SCC)数据对试验牛只进行隐性乳房炎分析,研究其对奶牛隐性乳房炎的防治效果,结果显示:饲喂5~10d乳酸菌微生态制剂后,奶牛平均体细胞数显著降低23.8%~62.8%。结果表明,本试验所用复合乳酸菌微生态制剂可应用于奶牛隐性乳房炎的防治。
This study choose the Holstein cows which coming from different ranches as research objects, adding complex Lactobacillus probiotics dose to 100~200g/d per head (effective viable count≥1.5×109 cfu/g) which include Lactobacilluscasei HM-09 and Lactobacillusplantarum HM-10 and its metabolites. The DHI data was used to measure the effect of probiotics in the treatment of subclinical mastitis. The results showed that after feeding Lactobacillus probiotics for 5~10 days, the average somatic cells number of three groups was signiifcantly reduced, decline from 23.8% to 62.8%. The results proved that this complex Lactobacillus probiotics can prevent and treat the subclinical mastitis of dairy cows.
