Abstract
  1. Two experiments were conducted to examine the effect of feeding higher supplemental vitamin E (VE) concentrations on male reproductive variables, fertility and hatchability of quails. 2. In experiment 1, sixty 5-week-old male quails, reared in individual cages, were fed male breeder diets supplemented with 0, 75, 150, 225 or 300 IU alpha-tocopherol acetate/kg. At 10 weeks, observations on cloacal gland size, foam production, testes weight and blood samples for testosterone estimation were taken. 3. In experiment 2, 50 male and 50 female cage-reared quails (5 weeks old) were fed male breeder and layer rations, respectively, supplemented with 0, 75, 150, 225 or 300 IU/kg. At 13 weeks, 9 different mating pairs (5 pairs/group) were formed. Group 1 contained one control male and one control female in each of 5 pens. In groups 2 to 5, control males were paired with females on supplements of 75, 150, 225 or 300 IU/kg. In groups 6 to 9, control females were paired with males on supplements of 75, 150, 225 and 300 IU/kg. During subsequent adaptation and egg collection periods, each of 10 d, control layer ration was fed to all groups. All the eggs laid during the 10-d egg collection period were incubated artificially to estimate fertility and hatchability. The trial was repeated at 15 weeks. 4. Adult male quails receiving moderate supplemental VE (75 and 150 IU/kg) had a higher cloacal gland index, quantity of foam secretion, testicular weight and plasma testosterone than quails fed on either VE-deficient or more highly supplemented diets (225 and 300 IU alpha-tocopherol acetate/kg). 5. It was concluded that a supplement of 75 IU VE/kg in maize/soybean diet could provide the best reproductive performance of male breeder quails. Cloacal gland index, quantity of foam secretion, testicular weight and plasma testosterone can serve as indirect indicators of testicular activity and fertilising ability in quails. Supplemental VE did not affect the fertility and hatchability of male and female Japanese quails.
摘要
  1. 进行了两项实验,以研究在鹌鹑日粮中添加较高浓度的维生素E(VE)对雄性生殖变量、受精率和孵化率的影响。2. 在实验1中,60只5周龄的雄性鹌鹑单独饲养在笼中,饲喂添加了0、75、150、225或300国际单位醋酸α-生育酚/千克的雄性种鹑日粮。10周龄时,对泄殖腔腺大小、泡沫产生量、睾丸重量进行观察,并采集血液样本用于测定睾酮。3. 在实验2中,50只雄性和50只雌性笼养鹌鹑(5周龄)分别饲喂添加了0、75、150、225或300国际单位/千克的雄性种鹑日粮和蛋鸡日粮。13周龄时,组成9个不同的交配组合(每组5对)。第1组在5个栏舍中各包含1只对照雄性和1只对照雌性。在第2至5组中,对照雄性与分别添加了75、150、225或300国际单位/千克的雌性配对。在第6至9组中,对照雌性与分别添加了75、150、225和300国际单位/千克的雄性配对。在随后的适应期和采蛋期,为期10天,所有组均饲喂对照蛋鸡日粮。在10天的采蛋期内所产的所有蛋都进行人工孵化,以评估受精率和孵化率。该试验在15周龄时重复进行。4. 与饲喂缺乏VE或添加量更高的日粮(225和300国际单位醋酸α-生育酚/千克)的鹌鹑相比,接受中等添加量VE(75和150国际单位/千克)的成年雄性鹌鹑具有更高的泄殖腔腺指数、泡沫分泌量、睾丸重量和血浆睾酮水平。5. 得出的结论是,在玉米/大豆日粮中添加75国际单位VE/千克可使雄性种鹑获得最佳繁殖性能。泄殖腔腺指数、泡沫分泌量、睾丸重量和血浆睾酮可作为鹌鹑睾丸活性和受精能力的间接指标。添加VE对日本鹌鹑雄性和雌性的受精率和孵化率没有影响。
