发酵茅台白酒糟及可溶物对蛋鸡产蛋性能、蛋品质、粪便微生物的影响

Effects of fermented-maotai distiller’grain with solubles on laying performance,egg quality,fecal microorganisms of laying hens

为研究不同水平发酵茅台白酒糟及可溶物(FMDGS)对蛋鸡产蛋性能、蛋品质、粪便微生物的影响,试验选取健康、体况基本一致的30周龄罗曼粉蛋鸡1200只,随机分为对照组和3个试验组,对照组饲喂基础日粮,试验Ⅰ、Ⅱ、Ⅲ组分别在基础日粮中添加1.5%发酵茅台白酒糟(FMDG),1.5%FMDGS,1%FMDGS,每组5个重复,每个重复60只鸡。预试期10 d,正试期40 d。结果表明:与对照组相比,试验Ⅱ、Ⅲ组在试验21~40 d产蛋率分别显著提高0.78个百分点和1.43个百分点(P<0.05),1~40 d试验组产蛋率有提高趋势(P=0.08);与对照组相比,试验Ⅱ组蛋形指数显著提高(P<0.05);与对照组相比,试验各组蛋鸡粪便中芽孢杆菌数量均显著增加(P<0.05)。添加1.5%FMDG,1.5%FMDGS,1%FMDGS均能不同程度改善蛋鸡产蛋性能,提高蛋品质,促进有益菌的增殖。综合来看,日粮添加1.5%FMDGS,蛋鸡产蛋性能、蛋品质、粪便微生物指标表现最好,效果最佳。

The experiment was to investigate the effect of different levels of fermented-maotai distillers’grain with solubles(FMDGS)on the laying performance,egg quality,fecal microorganisms in laying hens.A total of 1200 healthy Roman pink laying hens at 30 weeks of age with the same physical condition were divided into control groups and 3 experiment groups.The control group was fed the basal diet,and experiment group I,II,III were respectively added 1.5%fermented-maotai distiller'grain(FMDG),1.5%and 1%FMDGS to the basal diet,containing 5 replicates with 60 hens respectively.The pre-feeding lasted for 10 days,and the formal feeding lasted for 40 days.The results showed that:Compared with the control group,laying rate of experiment group II,III significantly increased respectively 0.78 percentage points and 1.43 percentage points from 21 days to 40 days and experiment groups tended to increase laying rate at 40 days(P=0.08);Moreover,compared with the control group,the egg shape index of experiment group II significantly increased(P<0.05);Furthermore,Bacillus in the feces of laying hens of experiment groups significantly increased(P<0.05).Dietary 1.5%FMDG,1.5%and 1%FMDGS supplementation could improve laying performance of laying hens to varying degree,increase egg quality and promote proliferation of fecal microbes.Taken together,dietary 1.5%FMDGS supplementation result in the best performance and effect in terms of laying performance,egg quality and fecal microbes for laying hens.
