摘要

本试验旨在研究霉菌毒素吸附剂(分别命名为CZ和SF)对产蛋鸡生产性能、蛋黄中微量元素含量、血清抗氧化和生化指标的影响。选取216只38周龄健康的罗曼蛋鸡,随机分成3个组,每组6个重复,每个重复12只。对照组饲喂基础饲粮,试验组(CZ组、SF组)分别在基础饲粮中添加0.5 g/kg的CZ和SF。预试期为10 d,正试期为35 d。结果表明:1)与对照组相比,CZ组产蛋鸡试验3~5周产蛋率、日产蛋量显著提高(P<0.05);饲粮中添加霉菌毒素吸附剂对产蛋鸡的平均蛋重、平均日采食量、料蛋比和死淘率均无显著影响(P>0.05)。2)与对照组相比,各试验组产蛋鸡第14天和第35天蛋黄铜、锰含量均无显著差异(P>0.05);CZ组第14天蛋黄锌含量显著提高(P<0.05)。3)饲粮中添加霉菌毒素吸附剂对第14天和第35天产蛋鸡血清谷胱甘肽过氧化物酶活性和丙二醛含量无显著影响(P>0.05)。与对照组相比,各试验组产蛋鸡第14天血清总抗氧化能力均显著提高(P<0.05);SF组第35天血清总超氧化物歧化酶活性显著提高(P<0.05)。4)与对照组相比,CZ组产蛋鸡血清碱性磷酸酶活性、葡萄糖含量显著降低(P<0.05);SF组血清总胆固醇含量显著降低(P<0.05)。由此可见,饲粮中添加霉菌毒素吸附剂CZ明显提高了产蛋鸡产蛋性能,2种吸附剂CZ和SF都增强了产蛋鸡血清抗氧化功能,改善了部分血清生化指标。

Abstract

This experiment was conducted to study the effects of mycotoxin adsorbents (named CZ and SF) on performance, yolk trace element contents and serum antioxidant and biochemical indices of laying hens. A total of 216 healthy 38-week-old laying hens were randomly divided into 3 groups with 6 replicates per group and 12 hens per replicate. Hens in the control group were fed a basal diet, and hens in experimental groups (group CZ and group SF) were fed the basal diets supplemented with 0.5 g/kg CZ and SF, respectively. The adjustment period lasted for 10 days, and the experimental period lasted for 35 days. The results showed as follows:1) compared with the control group, the laying rate and daily egg production of group CZ were significantly increased during 3 to 5 weeks of experiment (P<0.05). Dietary mycotoxin adsorbents had no effect on the average egg weight, average daily feed intake, feed to egg ratio and mortality and cull rate (P>0.05). 2) Compared with the control group, while the contents of copper and manganese in yolk of experimental groups at the 14th and 35th day had no significant difference (P>0.05), the content of zinc in yolk of group CZ at the 14th day was significantly increased (P<0.05). 3) Dietary mycotoxin adsorbents had no effect on serum glutathione peroxidase activity and malonaldehyde content of laying hens at the 14th and 35th day (P>0.05). Compared with the control group, and the serum total antioxidant capacity of experimental groups at the 14th day was significantly increased (P<0.05), and the serum total superoxide dismutase activity of group SF at the 35th day was significantly increased (P<0.05). 4) Compared with the control group, the serum alkaline phosphatase activity and glucose content of laying hens of group CZ were significantly decreased (P<0.05), the serum total cholesterol content of group SF was significantly decreased (P<0.05). In conclusion, dietary supplemented with the mycotoxin adsorbent CZ improves the egg production of laying hens; both CZ and SF adsorbents enhance serum antioxidant capability and improve serum biochemical indices.
