奶牛纯中药乳头消毒剂的临床应用效果观察

The Clinical Observation of the Chinese Medicine Teat Disinfectant for Cows

将93头奶牛分成3组,1组31头用碘伏进行乳头药浴,2 组 32 头用鱼腥草、红花和明矾组成的中药乳头消毒剂进行药浴,30 头作为对照组,35 d的临床应用,结果如下:中药乳头消毒剂和碘伏能使临床型乳腺炎发病率降低,差异不显著(P>0 05);1组隐性乳腺炎的发病率,由药浴前的 58 1%下降到 48 4%,与对照组差异显著(P<0 05),2组隐性乳腺炎的发病率由药浴前的81 3%下降到药浴后的75%,与对照组差异显著(P>0 05);1 组和2组隐性乳腺炎的乳区发病率差异不显著(P>0 05),与对照组差异极显著(P<0 01);中药乳头消毒剂药浴后体细胞数和LDH活性明显降低,与药浴前差异显著(P<0 05);NAGase的活性药浴前后差异不显著(P>0 05),该中药乳头消毒剂对奶产量无显著影响。

Ninety-three cows were separated into 3 groups.31 cows in group 1 were treated with idophor by teat dipping.32 cows in group 2 were treated with Chinese medicine teat disinfectant which were made up of cordate houttuynia,safflower and alum by teat dipping too.30 cows without dipping were raised as control.The practice continued for 35 days.The result showed as follows:Both Chinese medicine teat disinfectant and idophor could reduce the incidence of clinical mastitis (P>0.05);The recessive mastitis incidence of the group 1 decreased from 58.1% to 48.4%,and the divergence (against) control was remarkable (P<0.05).The recessive mastitis incidence of the group 2 dropped from 81.3% to 75%,and the divergence (against) control was remarkable (P>0.05).The udder region incidence of the group 1 was not remarkable (against that) of the group 2 (P>0.05),and the incidence against control was significantly remarkable (P<0.01).The Chinese medicine teat disinfectant could decrease remarkably both SCC and activity of LDH (P<0.05).The activity of NAGase was not changed significantly (P>0.05).The Chinese medicine teat disinfectant did not affect the milk yields.
