本研究的目的是评价日粮维生素E对日本鹌鹑生殖和生产参数的影响。本试验采用完全随机设计，将240只雌性日本鹌鹑和80只雄性日本鹌鹑分为5个处理，每个处理4个重复。试验日粮为零对照组、30、60、120和240 mg kg-1维生素E组。生育力和总孵化率不受影响的治疗。对照组受精卵孵化率最低，胚胎死亡率最高（P < 0.05）。T2、T4组左侧睾丸重量显著高于对照组（p < 0.05）。雄性的右睾丸重量和血清FSH浓度不受处理的影响。在T5中观察到雄性的最高睾酮浓度（p < 0.05）。雌性的输卵管重量和长度以及卵巢重量和FSH浓度不受处理的影响。T4处理组雌激素浓度高于对照组（p < 0.05）。大部分的鸡蛋特性不受影响的治疗。但T2和T3组的产蛋量和产蛋率显著高于对照组（p < 0.05）。采食量和转化率没有显着差异的治疗。总之，膳食维生素E提高孵化受精卵，胚胎活力，蛋质量和生产率在日本鹌鹑。维生素E和硒对日本鹌鹑这些特性的影响值得进一步研究。
The aim of this study was to evaluate the effects of dietary vitamin E on reproductive and productive parameters in Japanese quails. A total number of 240 female and 80 male Japanese quail were divided into five treatments with four replications in a completely randomized design. Experimental diets were zero control, 30, 60, 120 and 240 mg kg-1 of vitamin E. Fertility and total hatchability were not affected by treatments. But, the lowest hatch of fertile eggs and the highest embryonic death were observed in control group (p < 0.05). Left testes weight in T2 and T4 was higher than control (p < 0.05). Right testes weight and sera FSH concentration in males were not affected by treatments. The highest testosterone concentration of males was observed in T5 (p < 0.05). Weight and length of oviduct as well as weight of ovary and FSH concentration in females did not affected by treatments. Estrogen concentration in T4 treatment was greater than control (p < 0.05). Most of the egg characteristics were not affected by treatments. However, higher egg mass and production rates were observed in T2 and T3groups than control group (p < 0.05). Feed intake and conversion ratio did not differ among treatments. In conclusion, dietary vitamin E improved hatch of fertile egg, embryonic viability, egg mass and production rates in Japanese quail. The effect of dietary vitamin E combined with selenium on these characteristics are recommended for future study in Japanese quail.
