摘要

本试验旨在研究酵母硒和纳米硒对鹌鹑产蛋后期生产性能、蛋品质、蛋中硒含量及血清抗氧化指标的影响。选用300只300日龄健康产蛋鹌鹑，随机分成5组，每组6个重复，每个重复10只。对照组饲喂基础饲粮，试验组分别在基础饲粮中添加0.2、0.4 mg/kg酵母硒和0.2、0.4 mg/kg纳米硒。预试期7 d，正试期42 d。结果表明：1）与对照组相比，0.2 mg/kg酵母硒组料蛋比显著降低（P<0.05），0.4 mg/kg酵母硒组产蛋率显著提高（P<0.05）；0.2 mg/kg纳米硒组产蛋率和平均蛋重显著提高（P<0.05），料蛋比显著降低（P<0.05）；0.4 mg/kg纳米硒组产蛋率显著提高（P<0.05）。2）2种硒源对鹌鹑产蛋后期蛋形指数、蛋黄指数、蛋壳厚度无显著影响（P>0.05），但能极显著延缓鹌鹑蛋在储藏过程中哈氏单位的下降（P<0.01）。与对照组相比，0.4 mg/kg酵母硒和纳米硒组鹌鹑蛋的蛋黄色泽和哈氏单位均极显著提高（P<0.01）。3）与对照组相比，试验第14、28和42天，酵母硒和纳米硒组蛋中硒含量均极显著提高（P<0.01）。4）与对照组相比，酵母硒和纳米硒组血清谷胱甘肽过氧化物酶、总超氧化物歧化酶活性及总抗氧化能力均极显著提高（P<0.01），丙二醛含量极显著降低（P<0.01），纳米硒的抗氧化效果高于酵母硒。由此可见，鹌鹑产蛋后期饲喂纳米硒效果优于酵母硒，且以添加0.2 mg/kg的纳米硒为宜。

Abstract

This experiment was conducted to study the effects of yeast selenium and nano-selenium on performance, egg quality, egg selenium content and serum antioxidant indices of quails during the late laying period. A total of 300 healthy quails (300 days of age) were randomly divided into 5 groups with 6 replicates per group and 12 quails per replicate. Quails in the control group were fed a basal diet, and quails in experimental groups were fed the basal diet supplemented with 0.2, 0.4 mg/kg yeast selenium and 0.2, 0.4 mg/kg nano-selenium, respcitively. The adjustment period lasted for 7 days, and the experimental period lasted for 42 days. The results showed as follows: 1) compared with the control group, the feed to egg ratio in 0.2 mg/kg selenium yeast group was significantly decreased (P<0.05), and the laying rate in 0.4 mg/kg selenium yeast group was significantly increased (P<0.05); the laying rate and average egg weight in 0.2 mg/kg nano-selenium group were significantly increased (P<0.05), and the feed to egg ratio was significantly decreased (P<0.05); the laying rate in 0.4 mg/kg nano-selenium group was significantly increased (P<0.05). 2) Two kinds of selenium sources had no significant effects on shape index, yolk index and shell thickness during the late laying period (P>0.05), but it could significantly delay the decrease of Haugh units during storage (P<0.01). The yolk color and Haugh unit in 0.4 mg/kg yeast selenium and nano-selenium groups were significantly increased compared with the control group (P<0.01). 3) At the 14th, 28th and 42nd days, the egg selenium content in nano-selenium and selenium yeast groups was significantly increased (P<0.01). 4) The serum glutathione peroxidase, total superoxide disumutase activⅡes and total antioxidative capacity in nano-selenium and selenium yeast groups were significantly increased (P<0.01), but the malondialdehyde content was significantly decreased compared with the control group (P<0.01). The antioxidant effect of nano-selenium was better than that of selenium yeast. In conclusion, feeding effect of nano-selenium is better than selenium yeast of quails during the late laying period, and the optimal supplemental level of nano-selenium is 0.2 mg/kg.
