摘要

本试验旨在研究饲粮中添加高剂量植物甾醇对产蛋鸡生产性能、血液常规指标和血清生化指标的影响,以确定植物甾醇对产蛋鸡的安全性。选取体重和产蛋率相近的21周龄海兰褐蛋鸡360只,随机分为5组,每组6个重复,每个重复12只。对照组饲喂基础饲粮,试验组饲喂在基础饲粮中分别添加20、80(最高推荐有效剂量)、400(5倍最高推荐有效剂量)、800 mg/kg(10倍最高推荐有效剂量)植物甾醇的试验饲粮,预试期3周,试验期12周。结果表明:植物甾醇对产蛋鸡产蛋率、采食量、产蛋量和料蛋比均无显著影响(P>0.05),对各项血液常规指标均无显著影响(P>0.05)。植物甾醇仅对血液葡萄糖含量有显著影响(P<0.05),葡萄糖含量与植物甾醇添加量呈显著线性关系(P=0.010),对其他血清生化指标没有显著影响(P>0.05)。可知,在产蛋鸡饲粮中添加高剂量植物甾醇对产蛋鸡本身没有副作用。

Abstract

This experiment was conducted to evaluate the safety of high doses of phytosterol supplementation in laying hens by determining production performance, blood routine parameters and serum biochemical parameters. Three hundred and sixty 21-week-old Hy-Line Brown laying hens with the similar body weight and laying rate were randomly assigned to 5 groups with 6 replicates per group and 12 birds each. Birds were fed basal diets supplemented with 0 (control), 20, 80 (the maximum recommended available dose, MRAD), 400 (five fold of MRAD) and 800 mg/kg (ten fold of MRAD) phytosterol for 12 weeks, respectively. All birds were acclimated to the basal diet for 3 weeks. The results showed as follows: phytosterol had no significant effects on laying rate, feed intake, egg mass, the ratio of feed to egg and blood routine parameters (P>0.05). Only serum glucose content was significantly affected by phytosterol supplementation (P<0.05), and there was a significant linear correlation between them (P=0.010), while there were no significant differences in other serum biochemical parameters among five groups (P>0.05). It is indicated that no adverse effects are observed in laying hens by the high doses of phytosterol supplementation.
