| 摘 要： | 将567只14周龄的粤黄母鸡分为7个组饲养于双层的种鸡笼中，各组饲以不同的日粮：I)对照组，饲喂无外源添加锌和蛋氨酸的玉米—豆粕型基础日粮；Ⅱ)饲喂添加氧化锌的相同基础日粮；Ⅲ)饲喂添加蛋氨酸的相同基础日粮；Ⅳ)饲喂按N．R．C标准配制的基础日粮；V)饲喂添加低剂量蛋氨酸锌的基础日粮；Ⅵ)饲喂添加中剂量蛋氨酸锌的基础日粮；Ⅶ)饲喂添加高剂量蛋氨酸锌的基础日粮．上述日粮中锌的水平分别为：30．09，70．09，30．09，70．09，78．69，97．19和134．20mg/kg．蛋氨酸的水平分别为：0．28％，0．28％，0．36％，0．36％，0．37％，0．38％和0．38％．实验表明：日粮中添加外源性的锌和蛋氨酸可影响母鸡的蛋质量、受精率、孵化率和血浆中孕酮和雌激素的水平，其中，锌水平分别为70．09，70．09和78．69mg／kg；蛋氨酸的水平分别为0．28％，0．36％和0．37％的第Ⅱ、第Ⅳ和第Ⅴ组，上述指标均显著高于对照组，但日粮中Zn和蛋氨酸的量高于78．69mg/kg和0．37％水平，对种鸡的受精率、孵化率、产蛋量以及血浆中孕酮和雌激素均无促进作用．

| Abstract: | At 14 weeks of age, 567 female broiler breeders were housed in two step battery cages and fed either I) a corn-soybean (CSB) diet with no supplement of Zn or Methionine(control). II) a CSB diet supplemented with ZnO and no Methionine(Met). III) a CSB diet supplemented with Met and no Zn. IV) a CSB diet supplemented with Zn-Met N.R.C. values. V) a CSB diet supplemented with Zn-Met (low level). VI) a CSB diet supplemented with Zn-Met (med. level) and VII) a CSB diet supplemented with Zn-Met (high level). These diets contained 30.09, 70.09, 30.09, 70.09, 78.69, 97.19 and 134.20 mg Zn of one kilogram diet, respectively. The Met values were 0.28%, 0.28%, 0.36%, 0.36%, 0.37%, 0.38% and 0.38%, respectively. Supplemental Zn of ZnO or Zn-Met in CSB resulted in differences in egg mass, fertility, hatchability, egg production and plasma levels of estrogen and progesterone. In all cases groups Ⅱ, Ⅳ and Ⅴ with levels of 70.09, 70.09 and 78.69 mg/kg Zn and 0.28%, 0.36% and 0.37% Met respectively showed significant increase (P < 0.05), compared to the control group. However, levels of Zn-Met higher than 78.69 mg/kg Zn and 0.37% Met did not result in any increase in hatchability, fertility, egg production and plasma concentrations of estrogen and progesterone. |
