本试验旨在探讨提高饲料中维生素E(VitE)水平的效果。E)对雄性日本鸣禽(Coturnix Coturnix Japan)泄殖腔腺体大小、泡沫产生和精液特性的影响。将180只1日龄日本公鸡随机分为3组，每组6只，试验期为25周。每个处理由三个重复组成，每个重复包含20只雏鸡。基础日粮中添加15IU Vit。E/kg，两个试验日粮分别添加150和300IU Vit。E/kg(分别饲喂T-2和T-3日粮)。以维生素Dα-生育酚醋酸酯为原料制备维生素E。所有雏鸡都得到了自由饮用的饲料和水。在泡沫特征方面，T2组泡沫排出频率(24小时)、泄殖腔腺体指数和泡沫重量显著高于对照组(P<；0.05)。体重、睾丸重量(左侧和右侧)和血浆睾酮浓度没有显著差异。精液特征(精液量、精子活力、活精率、孵化率和精子密度)无显著差异(P>；0.05)。T2组精子畸形率和死亡率显著低于对照组(P<；0.05)，生育率显著高于对照组(P<；0.05)。从这项研究可以得出结论，适量补充膳食维生素。E可能有利于日本雄性鹌鹑的泡沫产生、泄殖腔腺体和精液品质的改善。(C)2006 Elsevier Inc.保留所有权利。
This experiment was to investigate the effects of increasing the level of dietary Vitamin E (Vit. E) on cloacal gland size, foam production and semen characteristics of male Japanese quail (Coturnix coturnix Japonica). One hundred and eighty male Japanese quail chicks (day old) were randomly distributed to three dietary treatments for a period of 25 weeks. Each treatment comprised of three replicates each containing 20 chicks. The basal diet contained 15 IU Vit. E/kg and the two experimental diets were supplemented with 150 and 300 IU Vit. E/kg (diets T-2 and T-3, respectively). DL alpha-tocopherol acetate was used as the source of Vit. E. All chicks were provided feed and water ad libitum. Foam characteristics, in terms of frequency of foam discharge (24 h), cloacal gland index and foam weight were significantly higher (P < 0.05) in T2 group. Body weight, testes weight (left and right) and plasma testosterone concentrations did not differ significantly. Semen characteristics (semen volume, sperm motility, % live sperm, % hatchability and sperm concentrations) did not differ significantly (P > 0.05). Percentages of abnormal and dead spermatozoa were significantly (P < 0.05) lower and fertility was higher (P < 0.05) in the T2 group. From this study, it can be concluded that moderate supplementation of dietary Vit. E may be beneficial for foam production, cloacal gland and improve the semen characteristics in male Japanese quail.
