摘　　要：本试验旨在研究糖萜素对蛋鸽产蛋性能、蛋品质以及蛋营养成分的影响。选取7月龄双母配对成功的白羽王鸽2000对,随机分为5组(每组5个重复,每个重复80对),对照组饲喂基础饲粮,试验组饲喂在基础饲粮中分别添加250、500、750、1000 mg/kg糖萜素的试验饲粮,试验期1年。结果表明:1)相较于对照组,饲粮添加750 mg/kg的糖萜素显著提高了产蛋量(P<0.05),其他组之间差异不显著(P>0.05),同时降低了死淘率。以各组年产蛋量为判断指标,通过二次曲线拟合分析,推荐糖萜素添加量为776 mg/kg。2)相较于对照组,饲粮添加750 mg/kg的糖萜素可使鸽蛋的蛋黄颜色极显著提高(P<0.01),蛋黄重显著升高(P<0.05),蛋形指数和蛋白重显著降低(P<0.05),其他蛋品质指标差异不显著(P>0.05)。3)相较于对照组,饲粮添加750 mg/kg的糖萜素可以显著提高鸽蛋中氨基酸总量、脂肪酸总量,尤其是多不饱和脂肪酸含量(P<0.05),而胆固醇含量差异不显著(P>0.05)。由此可见,饲粮添加糖萜素能提高蛋鸽产蛋性能,其中添加750 mg/kg的糖萜素效果最佳,能改善蛋黄颜色,提高蛋黄重,提高氨基酸总量、脂肪酸总量,尤其是不饱和脂肪酸含量。The experiment was conducted to study the effects of saccharicter-penin on the egg laying performance of egg pigeons,quality and nutritional composition of eggs.A total of 2000 pairs of 7-month-old White King pigeons were randomly divided into 5 groups(5 replicates in each group and 80 pairs in each replicate).Control group was fed a basal diet,while experimental groups were fed the basal diet supplemented with 250,500,750 and 1000 mg/kg of saccharicter-penin,respectively.The experiment lasted for one year.The results showed as follows:1)compared with the control group,dietary 750 mg/kg saccharicter-penin significantly increased egg production(P<0.05),but there was no significant difference among other groups(P>0.05),and decreased the mortality rate.Taking the annual egg production of each group as the judgment index,according to the quadratic curve fitting analysis,776 mg/kg of saccharicter-penin was recommended.2)Compared with the control group,adding 750 mg/kg of saccharicter-penin to the diet significantly improved the color of pigeon egg yolks(P<0.01),significantly increased egg yolk weight(P<0.05),and significantly reduced egg shape index and albumen weight(P<0.05),while there was no significant difference in other egg quality indicators(P>0.05).3)Compared with the control group,adding 750 mg/kg of saccharicter-penin to diet can significantly increase the total amino acids and fatty acids contents in pigeon eggs,especially polyunsaturated fatty acids(PUFA)content(P<0.05),while the difference in cholesterol content was not significant(P>0.05).In conclusion,saccharicter-penin can improve the egg laying performance of egg pigeons,adding 750 mg/kg of saccharicter-penin has the best effect,which can improve egg yolk color,increase egg yolk weight,increase total amino acid and fatty acid contents,especially PUFA.
