摘要
本研究旨在探讨饲粮棕榈粕添加水平对产蛋期蛋鸭产蛋性能、蛋品质、器官发育及抗氧化功能的影响,为生产中棕榈粕在蛋鸭饲粮中的科学应用提供参考。选择600只健康的20周龄福建龙岩麻鸭,随机分为5个组,每组6个重复,每个重复20只鸭。各组蛋鸭分别饲喂棕榈粕添加水平为0、3%、6%、9%和12%的试验饲粮。试验期12周。结果表明:饲粮棕榈粕添加水平对蛋鸭平均蛋重、蛋黄重和蛋壳重有显著影响(P<0.05),随着饲粮棕榈粕添加水平的升高,平均蛋重、蛋黄重和蛋壳重呈下降趋势;饲粮棕榈粕添加水平对其他产蛋性能和蛋品质指标均无显著影响(P>0.05)。饲粮棕榈粕添加水平对蛋鸭血浆和肝脏抗氧化指标及器官重量均无显著影响(P>0.05)。由此可见,以平均蛋重为评价指标,推荐蛋鸭饲粮中棕榈粕添加水平不高于3%;饲粮中棕榈粕添加水平达6%~12%时可降低平均蛋重,但并未影响蛋鸭器官发育和抗氧化功能。
The purpose of this experiment was to study the effects of dietary palm kernel meal supplemental level on laying performance,egg quality,organ development and antioxidant function of laying ducks during laying period,and to provide reference for the scientific application of palm kernel meal in duck diets.A total of 600 healthy Fujian Long-Yan ducks with similar body weight were randomly allotted into 5 groups with 6 replicates per group and 20 ducks per replicate.Ducks in each group were fed experimental diets which the palm kernel meal supplemental levels were 0,3%,6%,9% and 12%,respectively.The experiment last for 12 weeks.The results showed that dietary palm kernel meal supplemental level had significant effects on average egg weight,yolk weight and eggshell weight of laying ducks(P<0.05),with the dietary palm kernel meal supplemental level increased,the average egg weight,yolk weight and eggshell weight showed a decrease trend;dietary palm kernel meal supplemental level had no significant effects on other laying performance and egg quality indexes(P>0.05).Dietary palm kernel meal supplemental level had no significant effects on plasma and liver antioxidant indexes and organ weight of laying ducks(P>0.05).In conclusion,taking the average egg weight as the evaluation index,it is recommended that the dietary palm kernel meal supplemental level of laying duck is not higher than 3%;when dietary palm kernel meal supplemental level is 6% to 12%,the average egg weight is decreased,but has no effects no organ development and antioxidant function of laying ducks.
