摘要
营养不仅可以促进鸡的生长发育和繁殖,而且能够提高鸡的免疫功能。如果鸡缺乏营养就会引起生长发育迟缓,免疫器官重量减轻,淋巴细胞等免疫细胞的数量减少,免疫作用减弱,以至引起免疫功能下降。而给鸡适当添加蛋白质、氨基酸、脂肪酸、维生素、矿物质等营养物质,则可以促进免疫器官的发育,提高机体的免疫力,进而加快鸡的生长速度,提高养鸡的经济效益。
Nutrition not only can speed chicken's growth and breed, but also improve chicken's immunologic function. In practice examination, if nutrition is lack, the chicken will grow slowly, the weight of immune organ will be lighter, the quantity of immune cells such as lymphocyte will decrease gradually, the effect of immunity abates, so the immune function bring down. If certain nutrient such as protein, amino acid, fattiness, vitamin, mineral substance is added, the growth of chicken's immunity organ will be speeded, the immune ability will be strengthened, the chicken grows faster, and economic effect of raising chicken will be improved.
