摘  要：
为研究马齿苋对东乡黑鸡产蛋性能及大肠杆菌和乳酸杆菌的影响,试验选择产蛋高峰期体况良好东乡黑鸡48只,按体重和产蛋数量基本相同原则分为4个处理组,每个处理组3个重复,每个重复4只。分别饲喂添加0%、1%、2%和3%马齿苋的日粮,试验期为35 d。从第10天开始收集鸡蛋直至试验结束,并在第20、35天收集蛋鸡早晨的粪便测定其大肠杆菌和乳酸杆菌的含量。结果显示:(1)与对照组相比,日粮中添加2%和3%马齿苋组产蛋数提高49.5%和67.7%,添加1%、2%和3%马齿苋组产蛋率分别提高15.4%、23.1%、26.9%和料蛋比分别降低了16.6%、17.4%、17.6%,差异显著(P﹤0.05)。(2)与对照组相比,日粮中添加3%马齿苋组肠道乳酸杆菌提高一倍,添加3%马齿苋组肠道中大肠杆菌数降低57.9%,差异显著(P﹤0.05),且乳酸杆菌与大肠杆菌数比值比对照组提高了39.0%。综上,日粮中添加3%的马齿苋可以优化蛋鸡肠道中乳酸杆菌和大肠杆菌,提高蛋鸡的抗病能力。

摘  要：
A total of 48 healthy Dongxiang black chicken were chosen to investigate the effects of Purslane on laying performance,Escherichia coli and Lactobacillus. Based on the similar body weight and laying performance,they were divided into 4 treatments,which were fed with basal diet,1%,2%,3% Purslane in basal diet respectively,each treatment has 3 repeats and there were 4 layers in each repeat. All studies conducted lasted for 35 days,in which the eggs were collected from the 10 th day to the end for evaluating the laying performence and the chicken manure were collected in the 20 th and 35 th day morning for testing the contents of Escherichia coli and Lactobacillus. The results showed that:(1)Groups which treated with 2% and 3% Purslane in the diet,the number of laying eggs were increased by 49.5% and 67.7%. In all groups treated with Purslane,the egg production were increased by 15.4%,23.1% and 26.9%,the feed to egg ratio were reduced by 16.6%,17.4% and 17.6%,both differences were significant(P < 0.05).(2)Group which treated with 3% Purslane in the diet,the number of intestinal Lactobacillus was increased 100% and the number of Escherichia coli was reduced by 57.9%,both differences were significant(P < 0.05),thereby optimize the intestinal flora of layers through impoving the Lactobacillus/Escherichia coli ratio(39% of control),as a consequence,strengthen the anti-disease ability.
