日粮中添加蛋氨酸锌对粤黄鸡繁殖性能和血浆中雌激素和孕酮水平的影响
Effects of Supplemental Dietary Zinc-Methionine on the Reproductive Performance and Plasma Levels of Estrogen and Progesterone of Yuehuang Broiler Breeders
摘要
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.关键词
