氯己定碘溶液对奶牛乳头消毒效果的研究
Study on the antiseptic effect of chlorhexidine iodine solution on dairy cows' teats
摘要
Abstract
To evaluate the effect of chlorhexidine iodide solution on teat disinfection,ninety lactating cows were randomly and evenly divided into 3 groups.Group Ⅰ and group Ⅱ were committed to teat dip of chlorhexidine iodine solution and povidone iodine solution separately,whereas group Ⅲ was no treatment.The study lasted for 12 weeks.The results showed that:1) Cow daily milk production and somatic cell count (SCC) value of group Ⅰ and group Ⅱdisplayed no significant changes compared to pre-experiment (P＞0.05).The average daily milk cow production and SCC value of group Ⅲ respectively declined and increased significantly in 12 weeks (P＜0.01).2) The udder infection rate (33.3％ VS 46.7％) and the quarter infection rate (11.7％ VS 26.7％) of group Ⅰ and group Ⅱ decreased significantly (P＜0.01 or P＜0.05).Significant increase were observed in group Ⅲ cows (P＜0.05).3) After 12 weeks experiment,udder clearance rate (60.0％) and quarter clearance rate (83.3％) of group Ⅰ were significantly higher than those of group Ⅱ (44.0％ and 50.0％).But the udder clearance rate and quarter clearance rate of group Ⅲ was 0.In conclusion,the application of cow teat dipping pre-and post-milking could effectively prevent the risk of infection.It was better to use chlorhexidine iodine solution to disinfect teats than povidone iodine solution.关键词
