摘要
旨在研究联合使用发酵饲料和发酵中草药微生态制剂替代饲用抗生素对蛋鸡的影响,选取304日龄的海兰灰蛋鸡为试验对象,随机分为对照组和试验组,对照组饲喂基础日粮+2 kg/t氨苄西林,试验组饲喂基础日粮+3%发酵饲料+3 kg/t发酵中草药制剂。结果表明,试验组在粪便成形度方面明显好于对照组,试验第46天、第175天产蛋率显著提高(P<0.05);试验第175天,试验组死淘率及破蛋率与对照组相比,分别降低了25.00%、18.05%,蛋黄颜色差异显著(P<0.01),鸡蛋的禽流感H9抗体水平和新城疫抗体水平显著高于对照组(P<0.05)。发酵饲料和发酵中草药微生态制剂联合使用,在蛋鸡养殖中可以达到抗生素使用的效果。
This experiment was designed to study the effect of replacement of feeding antibiotics with the combination of a fermented feed and probiotics prepared with fermented Chinese herbal medicine on production performance of laying hens. The 304-day-old Hy-line laying hens were selected and randomly divided into control group and experiment group. The control group was fed with basal diet with 2 kg/t of ampicillin, while the experiment group was fed with basal diet with the combination of 3% of fermented feed and 3 kg/t of probiotics prepared with fermented Chinese herbal medicine. The results showed that the fecal formability of the experiment group was significantly better than that of the control group, and the egg laying rate was significantly increased on the 46^th and 175^th experimental day (P〈0.05); on the 175^th day, the death and culling rate and egg breaking rate of the experiment group were reduced by 25.00%, 18.05%, respectively, and the yolk color was significantly different from that of the control group (P〈0.01); the antibody levels against avian influenza H9 virus and Newcastle disease virus in eggs in the experimental group were significantly higher than those in the control group (P〈0.05). In summary, the combination uses of the fermented feed and probiotics prepared with fermented Chinese herbal medicine may serve as a good alternative for feeding antibiotics in laying hen breeding.
