白头翁散和微生态制剂对鸡白痢疗效的试验

Research on Different Drug's Efficacy on Pullorum

试验分别进行预防对比试验、雏鸡治疗试验及阳性种鸡治疗试验三种类型,预防对比和雏鸡治疗试验分别各选取400只1日龄的健康雏鸡,阳性蛋种鸡治疗试验选取400只240日龄确诊为鸡白痢的种鸡,预防对比和雏鸡治疗试验两个类型各随机分为4个组,每个组100只,试验Ⅰ(白头翁)、试验Ⅱ(微生态制剂)、试验Ⅲ(白头翁+微生态制剂)及CK,试验为期30d;种鸡治疗试验则选取400只240日龄经检测呈阳性蛋鸡,随机分为3组,分别在饮水中添加试验Ⅰ(白头翁)、试验Ⅱ(微生态制剂)、试验Ⅲ(白头翁+微生态制剂),自由饮水5d,间隔5d重复治疗一次,共治疗3个疗程,以观察各组的治疗效果,试验期间各组的饲养管理均相同。结果表明:(1)对雏鸡预防效果方面,试验Ⅰ成活率为89%,试验Ⅱ成活率为85%,试验Ⅲ成活率高达97%,CK成活率为55%,试验Ⅲ的成活率分别比试验Ⅰ、试验Ⅱ和CK提高了8%(P<0.05)、12%(P<0.05)和42%(P<0.01);(2)在雏鸡治愈率方面,试验Ⅰ治愈率为80.46%,试验Ⅱ治愈率为66.67%,试验Ⅲ治愈率为85.39%,试验Ⅲ的治愈率分别比试验Ⅰ和试验Ⅱ提高了4.93%和18.72%;(3)经过3个疗程的治疗后,试验Ⅲ的死亡率分别比试验Ⅰ、试验Ⅱ及CK降低了11%、16%及26%。产蛋数分别比试验Ⅰ、试验Ⅱ和CK多产692枚、727枚和1810枚,检测阳性率分别比试验Ⅰ、试验Ⅱ和CK降低了52%、70%和77%。使用白头翁和微生态制剂结合起来,对预防和治疗鸡白痢,提高雏鸡提成率和产蛋量,降低阳性率效果最好。

In order to effectively reduce the harm of Salmonella pullorum on chicken,three types of tests were used：preventive comparison test group,treatment test group for chicken and treatment test group for Pullorum-positive breeding hens.The first two test groups selected 400one-day-old healthy chicks which were randomly divided into four groups,100 chicks in each group;while the third test group chose 400 240-day-old pullorum positive breeding hens,randomly divided into three groups.TreatmentⅠ（Pulsatilla）,treatmentⅡ（probiotics）,treatmentⅢ（Pulsatilla ＋ probiotics）and CK were adopted for the first two test groups with a test period of 30 d.As for the third test group,treatmentⅠ（Pulsatilla）,treatmentⅡ（probiotics）and treatmentⅢ（Pulsatilla＋ probiotics）were added in the drinking water for 5days,and repeated every 5d,altogether 3courses.The feeding and management remained the same during the test trials in each group.Results showed that：1as for the preventive effect on the chicks,the survival rate for treatment I was 89%,treatment II 85%,treatmentⅢ up to 97%respectively,while the survival rate for the CK was 55%.The survival rate of treatment III improved by 8%（P〈0.05）,12%（P〈0.05）and 42%（P〈0.01）compared with that of treatment I,II and CK;2 The cure rates of treatment I,II and III were 80.46%,66.67%,and 85.39%respectively.The cure rate of treatment III was 4.93%and 18.72% higher than that of treatment I and II;3 After three courses of treatment,the death rate of treatment III dropped by 11%,16% and 26%,respectively,compared with that of other treatments;and the hens in treatment III laid 692,727 and 1810more eggs than hens in other three treatments;and the positive rate reduced by 52%,70% and 77% compared with that of treatment I,II and CK.Therefore,combining pulsatilla and probiotics together can better prevent and treat salmonellosis,improve the survival rate,egg production and reduce the positive rate in chickens.
