复合中草药多糖提取物对籽鹅产蛋性能及蛋品质的影响

Effect of compound Chinese herbal polysaccharide extract on egg laying performance and egg quality of seed geese

为研究饲料中添加不同水平的复合中草药多糖提取物对籽鹅产蛋性能及蛋品质的影响,采用单因素随机设计试验,将600只产蛋期籽鹅随机分成4组,每组3个重复,每个重复50只,1组饲喂基础日粮为对照组,试验2、3、4组分别在基础日粮中添加1.0%、1.5%、2.0%的复合中草药多糖提取物,预饲期7 d,试验期56 d。结果表明:(1)试验2、3、4组的产蛋率、商品合格率、日均采食量均高于1组(P>0.05),试验3、4组的平均蛋重较1组比分别提高6.1%、4.3%(P<0.05),试验3、4组的料蛋比较1组比分别降低13.1%、12.8%(P<0.05);(2)试验3、4组蛋壳强度、蛋壳厚度较1组比分别提高9.2%、7.7%、5.5%、5.2%(P<0.05),试验2、3、4组的哈夫单位、蛋形指数、蛋黄颜色均高于1组(P>0.05)。综上,不同水平的复合中草药多糖提取物添加可以提高籽鹅产蛋性能及蛋品质,以添加1.5%为适宜。

In order to study the effect of different levels of compound Chinese medicine polysaccharide extract on egg laying performance and egg quality of seed geese.600 laying geese were randomly divided into 4 groups,each group had 3 repetitions,each repetitions had 50 geese.The first group was fed with basic diet as control group.In the second,third and fourth groups,1.0%,1.5%and 2.0%compound Chinese medicine polysaccharide extract were added into basic diet,the pre feeding period was 7 days,and the experimental period was 56 days.The results showed that:(1)The egg laying rate,commodity qualification rate and average daily feed rate of test 2,3 and 4 groups were all higher than those of group 1(P>0.05),the average egg weight of test 3 and 4 groups were 6.1%and 4.3%higher than that of group 1 respectively(P<0.05),and the ratio of feed to egg in test 3 and 4 groups were 13.1%and 12.8%lower than that in group 1 respectively(P<0.05);(2)The eggshell strength and thickness of test 3 and 4 groups were 9.2%,7.7%,5.5%,5.2%higher than that of group 1 respectively(P<0.05).The haff unit,egg shape index and yolk color of test 2,3 and 4 groups were higher than those of group 1(P>0.05).In conclusion that different levels of polysaccharide extract could improve egg laying performance and egg quality,and 1.5%was suitable.
