This study investigated the effects of dietary supplementation with vitamin E (vit. E), selenium yeast (Se yeast), or both on egg incubation response, embryonic development, keet quality, and posthatch growth of helmeted guinea fowls. Two hundred and forty 24-week old helmeted guinea fowl hens (average weight 1.75 + 0.22 kg) and cocks (average weight 2.15 + 0.20 kg) were assigned into 24 pens; each pen housed 10 hens and 2 cocks. There were four dietary treatments consisting of a basal diet (control), basal diet supplemented with vit. E (30 IU/kg), Se yeast (0.3 mg/kg Se), or both. Six pens were assigned to each treatment. Egg incubation response were estimated using 504 settable eggs sampled from each treatment collected during 15 to 17 weeks in lay. A total of 72 fertile eggs sampled from each treatment were used for the estimation of embryonic development. Quality of day-old keets hatched was scored based on physical conditions, while posthatch growth was measured for 21 days. Guinea fowl breeders fed diet supplemented with both vit. E and Se yeast produced the highest (P < 0.05) number of fertile eggs, percentage fertility, number of hatchlings, hatchability of total eggs, and hatchability of fertile eggs. Supplementation with vit. E + Se yeast resulted in the heaviest (P < 0.05) embryo weight, relative embryo weight, least (P < 0.05) yolk sac weight, and relative yolk sac weight on 25 days of incubation. Hatchlings from breeders fed diet supplemented with Se yeast and vit. E + Se yeast showed normal swallowed yolk. Supplementation of maternal diet with vit. E, Se yeast, and vit. E + Se yeast resulted in improved (P < 0.05) feed conversion ratio of subsequent hatchlings during 1 to 7-day posthatch growth. It can be concluded that dietary supplementation of vit. E + Se yeast in guinea fowl breeders resulted in improved egg fertility, hatchability, heavier embryo weights, hatchlings of good quality, and improved posthatch growth during the first 7 days.

这项研究调查了日粮中添加维生素E（维生素E），硒酵母（硒酵母）或两者对卵状珍珠鸡孵化反应，胚胎发育，keet品质和孵化后生长的影响。240只24周龄的带头盔的珍珠鸡母鸡（平均体重1.75  +  0.22公斤）和公鸡（平均体重2.15  + 将0.20公斤）分配到24支钢笔中；每只钢笔饲养10只母鸡和2只雄鸡。有四种饮食疗法，包括基础饮食（对照），基础饮食补充维生素。E（30 IU / kg），Se酵母（0.3 mg / kg Se）或两者兼有。每种处理分配六支笔。使用从15到17周的产蛋期收集的每种处理中采样的504个可凝固卵来评估卵的孵化响应。每种处理共采样72个可育卵，用于估计胚胎发育。根据身体状况对孵化的日龄金鸡的质量进行评分，而孵化后的生长则要进行21天的测量。珍珠鸡饲养者饲喂补充了两种维生素的饮食。E和Se酵母产生最高（P <0.05）受精卵的数量，受精率，孵化数量，总卵的孵化率和受精卵的孵化率。补充维生素。E + Se酵母在 孵育25天后产生的 胚重最大（P <0.05），相对胚重，卵黄囊重量最小（P < 0.05）和卵黄囊相对重量。饲养员的雏鱼饲喂补充了硒酵母和维生素的饮食。E + Se酵母显示正常吞咽蛋黄。孕妇补充维生素。E，Se酵母和vit。E + Se酵母改善了（P <0.05）在孵化后1至7天的生长过程中后续孵化的饲料转化率。可以得出结论，饮食中补充维生素。珍珠鸡饲养者中的E + Se酵母可提高卵的繁殖力，孵化率，增加胚重，提高孵化质量，并在头7天内改善孵化后的生长。
