| 摘 要： | 试验旨在研究芽孢杆菌微生态制剂对京红1号蛋鸡产蛋性能和蛋品质的影响。选择健康、体况良好的404日龄京红1号蛋鸡960只,随机分为4组,每组6个重复,每个重复40只。对照组饲喂基础日粮,试验Ⅰ组饲喂基础日粮+益倍佳(凝结芽孢杆菌),试验Ⅱ组饲喂基础日粮+赐尔健(纳豆芽孢杆菌),试验Ⅲ组饲喂添加地衣芽孢杆菌+枯草芽孢杆菌(1∶1)混合制剂的日粮,试验组微生态制剂的添加量均为300 mg/kg。试验期25 d,其中预饲期5 d。结果显示,与对照组相比,试验组蛋鸡产蛋率均显著提高(P<0.05),破、软蛋率均显著降低(P<0.05),试验Ⅰ、Ⅱ组料蛋比显著降低(P<0.05)。与对照组相比,Ⅱ组鸡蛋平均蛋重显著提高了2.25%(P<0.05);试验组Ⅰ、Ⅱ的蛋黄相对重、蛋壳相对重、哈氏单位均无显著影响(P>0.05);试验Ⅲ组蛋壳颜色为1~3级的鸡蛋比例明显增多,差异显著(P<0.05)。综上所述,添加微生态制剂赐尔健(纳豆芽孢杆菌)可显著提高京红1号产蛋率和平均蛋重,显著降低料蛋比和破、软蛋率;添加枯草芽孢杆菌+地衣芽孢杆菌(1∶1)混合制剂可使蛋壳颜色加深的鸡蛋比例显著增多。

| Abstract: | This study was conducted to investigate the effects of microecological preparations of Bacillus on laying performance and egg quality of Jing Hong laying hens.Nine hundred and sixty healthy 404-day-old Jing Hong laying hens with consistent body condition were randomly allotted into 4 groups with 6 replicates per group and 40 hens per replicate.The laying hens in control group were fed with a basal diet.Experimental groupⅠwas fed with basic diet supplemented with Yibijia(Bacillus condensate),groupⅡwas fed with basal diet supplemented with Cierjian(Bacillus natto),groupⅢwas fed with basal diet supplemented with a mixture of Bacilluslicheniformis and Bacillus subtilis at 1∶1.Experimental groups were added 300 mg/kg microecological preparation in the basal diet.The test lasted for 25 days and the pre-test period lasted for 5 days.The results showed that compared with the control group,the egg laying rates of experimental groups were significantly increased(P<0.05),the soft and broken eggs rates were significantly decreased(P<0.05)and feed-egg ratio of experimental groupⅠandⅡwas significantly decreased(P<0.05).Compared with the control group,different probioties improved the egg weight by different degree,but only groupⅡwas significantly increased by 2.25%(P<0.05).Experimental group improved the egg weight,yolk relative weight,eggshell relative weight and Haugh unit by different degree,but the differences were not significant(P>0.05).The eggs proportion at grade 1 to 3 of groupⅢsignificantly increased(P<0.05).In conclusion,adding microecological preparation gierjian(Bacillus natto)could significantly improve the egg laying rate,egg weight and significantly decreased the feed-egg ratio,soft and broken eggs of Jing Hong laying hens.Adding Bacilluslicheniformis and Bacillus subtilis(1∶1)could significantly improve the eggs proportion of eggshell darkening. |
