摘要

本试验旨在研究植物精油混合物对海兰褐蛋鸡生产性能、蛋品质、卵泡发育及血清生殖激素指标的影响。选取432只体重和产蛋率接近的25周龄健康海兰褐蛋鸡，随机分为4组，每组6个重复，每个重复18只鸡。对照组饲喂玉米-豆粕型基础饲粮，试验组分别饲喂在基础饲粮中添加75、150和225 mg/kg植物精油混合物的试验饲粮。预试期3周，正试期12周。结果表明：1）150 mg/kg植物精油混合物组蛋重显著高于对照组（P<0.05）。各组间产蛋率、采食量、产蛋量和料蛋比无显著差异（P>0.05）。2）75和150 mg/kg植物精油混合物组哈氏单位显著高于225 mg/kg植物精油混合物组（P<0.05），150 mg/kg植物精油混合物组蛋白高度显著高于225 mg/kg植物精油混合物组（P<0.05），225 mg/kg植物精油混合物组蛋壳比例显著高于其他各组（P<0.05）。各组间蛋形指数、蛋壳颜色、蛋壳厚度、蛋壳强度、蛋黄颜色、蛋黄比例、蛋白比例无显著差异（P>0.05）。3）各组间蛋鸡卵泡发育指标无显著差异（P>0.05）。4）225 mg/kg植物精油混合物组血清孕酮含量显著高于其他各组（P<0.05）。各组间其他血清生殖激素含量无显著差异（P>0.05）。综上所述，饲粮中添加150 mg/kg植物精油混合物可改善蛋鸡的蛋重及蛋白品质，且对卵泡发育的影响较小。

Abstract

This study was conducted to investigate the effects of essential oil mixture (EOM) on performance, egg quality, follicular development and serum reproductive hormone indices of laying hens. A total of 432 twenty-five-week-old healthy Hy-Line Brown laying hens with similar body weight and laying rate were randomly divided to 4 groups with 6 replicates per group and 18 birds per replicate. Hens in the control group were fed a corn-soybean meal basal diet, and the others in the experimental group were fed the basal diets supplemented with 75, 150 and 225 mg/kg EOM, respectively. The adaptation period lasted for 3 weeks and the formal period lasted for 12 weeks. The results showed as follows:1) the egg weight of 150 mg/kg EOM was significantly higher than that of control group (P<0.05). However, there were no significant differences in laying rate, feed intake, egg production and feed to egg ratio among all groups (P>0.05). 2) The Haugh unit of 75 and 150 mg/kg EOM groups was significantly higher than that of 225 mg/kg EOM group (P<0.05), the albumen height of 150 mg/kg EOM group was significantly higher than that of 225 mg/kg EOM group (P<0.05), the eggshell ratio of 225 mg/kg EOM group was significantly higher than that of other groups (P<0.05). However, there were no significant differences in shape index, eggshell color, eggshell thickness, eggshell strength, yolk color, yolk ratio and albumen ratio among all groups (P>0.05). 3) There were no significant differences on follicular development indices among all groups (P>0.05). 4) The serum progesterone content of 225 mg/kg EOM group was significantly higher than that of other groups (P<0.05). However, there were no significant differences on other serum reproductive hormone contents among all groups (P>0.05). In conclusion, dietary EOM can improve egg weight and albumen quality of laying hens, while it has little effect on the follicular development.
