摘要:

为研究盐酸头孢噻呋乳房注入剂对干乳期奶牛临床使用的安全性,开展药物对健康奶牛的安全性研究,作者选择健康泌乳期奶牛12头(初产和经产各6头),四个乳区分别单次给予盐酸头孢噻呋乳房注入剂一支(规格10 mL:500 mg)。比较奶牛用药前后直肠温度、日产奶量、牛奶体细胞数和乳区病原菌的变化。整个试验期间对给药奶牛进行连续观察,记录是否出现红、肿、热、痛等临床症状。结果显示,与给药前相比,奶牛的直肠温度、日产奶量、牛奶体细胞数均无显著变化(P>0.05),乳区病原菌数量有所减少,同时,没有增加新的病原菌。结果表明,盐酸头孢噻呋乳房注入剂对干乳期奶牛正常体温、产奶量、奶中体细胞数和乳区菌群没有不良影响,该制剂用于奶牛是安全的。

Abstract:

 The aim of the study was to evaluate the safety of Ceftiofur Hydrochloride intramammary infusion (Dry Cow) for dairy cows.Twelve healthy lactating cows (include 6 primiparous cows and 6 multiparous cows) were selected for the research.There were 6 primiparous cows and 6 multiparous cows among them.All the cows had not been treated with any antibiotics by systemic or intramammary administration 30 days before.They were fed with food and water without any antibiotics and under normal conditions.All the cow’s udder regions were injected by the drug of Ceftiofur Hydrochloride intramammary infusions (Dry Cow),and one piece of drug (specification:10 mL/500 mg) was only used for one udder region.The differences of rectal temperature,daily yielding,somatic cells number and the changes of pathogen in milk before and after administration were compared.The changes of clinical symptoms were observed all the time during the experiment.The results showed that there were no significant differences in rectal temperature,daily yielding,somatic cells number before and after administration(P>0.05).The number of pathogen in milk was reduced than before and there was not any new pathogen appeared at the same time.The results indicated that Ceftiofur Hydrochloride intramammary infusion (Dry Cow) have no adverse effects to dairy cows.It was safe to dairy cows when administrated according to the dosing regimen above.
