复合添加剂对樱桃谷鸭孵化性能和血液生化指标的影响

Effects of Compound Additives on Hatchability Performance and Serum Biochemical Index in Cherry Valley Parent Stock

选取40周龄的樱桃谷鸭SM3父母代种鸭2400羽,随机分成5组,在1～4组的基础日粮中分别加入0.5%、0.2%、0.2%和0.2%的4种复合添加剂,第5组饲喂基础日粮。试验期为42 d。研究4种复合添加剂对樱桃谷种鸭的生产性能和血液生化指标的影响。结果表明,添加复合添加剂可以提高樱桃谷种鸭产蛋率,第1组和第4组产蛋率分别高出对照组1.04%和1.97%(P<0.05);4个试验组的平均蛋重和雏鸭初生重均低于对照组(P<0.05)。4个处理组的健雏率均高于对照组,其中第2、3和4组比对照组分别高0.88%、1.10%和0.92%(P<0.05)。日粮中添加复合添加剂后,4个处理组母鸭的血液生化指标与对照组间差异不显著;公鸭血液生化指标得到一定的改善,高密度脂蛋白胆固醇和碱性磷酸酶含量均显著高于对照组(P<0.05)。在种鸭日粮中添加复合添加剂可以提高种鸭的产蛋率,降低蛋重和改善血液生化指标。

Two thousand and four hundred Cherry valley super-M3 parent stocks at the age of forty weeks were selected and randomly allocated to five treatment groups with three replicates,four diets containing four different compound additives（0.5%,0.2%,0.2% and 0.2%） and basic diet were given to feed these ducks for 42 days in order to study the effects of 4 kinds of compound additives on performance and serum biochemical index in Cherry-valley super-M3 parent stock.The results showed that laying rates were increased with diets of compound additives.When compared to control group,the laying rates of group 1 and group 2 were significantly increased by 1.04%（P〈0.05） and 1.97%（P〈0.05）,respectively.The percentage of healthy chicks of four trail groups were significantly lower than control group（P〈0.05）.The egg-shape index and the percentage of yolk of group 2 was higher than control group and that of the group 2,3 and 4 were increased by 0.88%,1.10% and 0.92% than control group（P〈0.05）,respectively.There were no difference on serum biochemical index of the female between control group and the four trail groups,the serum biochemical index of the drake were improved and the concentrations of high-dense lipoprotein cholesterol and alkaline phosphatase were all increased than that of control group（P〈0.05）.The results from this study indicated that different kinds of compound additives in the duck feed could increase the laying rate and decrease egg weight and improve serum biochemical index of parent stock.
