摘要
[目的]探讨头孢噻呋晶体注射液对牛呼吸系统疾病的治疗效果。[方法]选择平度市某养殖场50头患呼吸系统疾病牛作为试验动物,随机分成对照组和试验组,对照组用咳喘清注射液,试验组用头孢噻呋晶体注射液。[结果]经治疗后,试验组临床评分显著低于对照组[(0.13±0.14)分和(0.66±0.21)分,P<0.05];ALP、AST、ALT、GLU、TCH、BUN等临床生化检验指标在两个处理组间差异显著(P<0.05),而临床生化检验指标TP值在两组病牛间比较,差异不显著[(68.13±5.73)g/L和(67.82±5.54) g/L,P>0.05]。头孢噻呋晶体注射液试验组病牛在临床上的治疗有效率显著高于对照组[(92.00%和76.00%),P<0.05]。对照组中有4例病牛出现不良反应现象,其不良反应发生率显著高于试验组(P<0.05)。[结论]头孢噻呋晶体注射液对牛呼吸系统疾病具有显著的临床疗效,且无明显不良反应,为畜牧兽医养殖制定科学、合理的牛临床疾病治疗方案提供参考。
[Objective]To analyze the effects of dietary supplementation with dandelion extract on the growth performance,lactation performance and immune indicators of dairy cows.[Method]A total of 160 dairy cows with similar body weight and parity were selected as the research objects in a large-scale dairy farm in Shan County.They were randomly divided into 4 groups by the random number table method,with 5 replicates in each group and 8 cows in each replicate.They were the control group,the low-dose group,the medium-dose group and the high-dose group respectively.The control group was fed with the basal diet,while the low-dose group,medium-dose group and high-dose group were respectively supplemented with 0.2%,0.4%and 0.6%dandelion extract on the basis of feeding the basal diet.The experimental period was 50 days.After the experiment,the growth performance,lactation performance and immune indicators of each group were analyzed.[Result]The average daily feed intake and average daily weight gain of dairy cows in the low-dose group,medium-dose group and high-dose group were significantly higher than those in the control group(P<0.05),and the feed conversion ratio of dairy cows in the medium-dose group was significantly lower than that in the control group(P<0.05).The indicators of milk production、milk protein rate、lactose rate of dairy cows in the low-dose group,medium-dose group and high-dose group were significantly higher than those in the control group(P<0.05),while the indicators of somatic cell number and milk urea nitrogen were significantly lower than those in the control group(P<0.05).The contents of IgM,IgG and IL-10 in dairy cows in the low-dose group,medium-dose group and high-dose group were significantly higher than those in the control group(P<0.05),and TNF-αwas significantly lower than that in the control group(P<0.05).[Conclusion]Under the conditions of this experiment,the optimal dosage of dandelion extract in the diet was determined to be 0.4%.Dietary supplementation with dandelion extract can promote the growth of dairy cows,improve lactation performance,and enhance immune function,providing a scientific basis for the rational use of natural additives in dairy farming.
