Two trials were conducted, each one using 240 Chinese Ringneck pheasant-breeder hens (Phasianus colchicus torquatus) to determine the effects of feeding various levels of brewers' dried grains (BDG) on egg production, fertility, hatchability, and feed consumption. The birds were subjected to natural daylight. Data were collected for 16 wk of egg production (April 1 through July 31). Each of four diets containing 0, 15, 30, or 45% BDG was fed to three pens (19 females and 1 male per pen), beginning 1 wk prior to the onset of lay. The eggs were collected twice daily and were stored at 13 C and were set in incubators every 14 days. The eggs were candled on Day 21 of incubation to determine the number of infertile eggs and dead embryos. The hatch was removed on Day 25. The egg production and fertility from BDG-fed hens did not differ from those of the control hens. The hatchability of fertile eggs was higher (P less than .05) from hens fed diets containing 30 and 45% BDG than from hens fed the control diet. The inclusion of BDG in the diets of pheasant-breeder hens had a favorable influence on the hatchability of eggs.
进行了两项试验，每项试验使用240只中国环颈雉种母鸡（Phasianus colchicus torquatus）来确定饲喂不同水平的啤酒糟干糟（BDG）对产蛋量、受精率、孵化率和采食量的影响。这些鸡接受自然光照。收集了16周产蛋期（4月1日至7月31日）的数据。在产蛋开始前1周，将四种分别含有0%、15%、30%或45%BDG的日粮中的每一种喂给三个鸡舍（每个鸡舍19只母鸡和1只公鸡）。每天收集两次鸡蛋，将其储存在13℃，并每14天放入孵化器中。在孵化第21天对鸡蛋进行照蛋，以确定未受精蛋和死胚的数量。在第25天取出孵化物。饲喂BDG的母鸡的产蛋量和受精率与对照母鸡没有差异。饲喂含有30%和45%BDG日粮的母鸡所产受精蛋的孵化率高于饲喂对照日粮的母鸡（P小于0.05）。在雉种母鸡日粮中添加BDG对鸡蛋孵化率有有利影响。
