摘要
试验观测了种母鸡饲粮锌和钙水平对子代雏鸡的影响和子代的补偿作用。结果表明,母子两代饲粮都未加锌时子代雏鸡增重和采食量显著降低(P<0.01);母代饲粮未加锌而子代加锌,虽然使子代增重和采食量有所提高,但并未消除母代未加锌对子代的不良影响。母代饲粮高钙使子代增重(P<0.05)和采食量(P<0.01)显著降低。种母鸡饲粮锌水平对子代雏鸡血清碱性磷酸酶活性的遗留影响较小,而子代的补偿作用较大。种母鸡饲粮高钙对子代雏鸡血清碱性磷酸酶活性没有显著影响(P>0.05)。母子两代饲粮都未加锌时子代血清总蛋白含量最低,子代加锌有一定的补偿作用。种母鸡饲粮高钙使子代雏鸡血清总蛋白(P<0.01)、血清白蛋白(P<0.01)和血清球蛋白(P<0.05)含量显著降低。种母鸡饲粮锌水平对子代组织中锌含量的遗留影响较小,而子代加锌后的补偿作用较大。种母鸡饲粮高钙时子代雏鸡组织中锌含量没有显著变化(P>0.05)。
Effects of zinc and calcium levels in hen diets on the filial chick and its compensation were studied. Weight gain and feed intake of the filial chick were significantly reduced when the dam and its chick were fed with zinc-unsupplemented diet ( P<0.01 ) . When the dam was fed with zinc-unsupplemented diet and the chick was fed with zinc-supplemented diet, weihgt gain and feed intake of the filial chick were bettered, but the ill effect from zinc-unsupplemented dam to the filial chick was not all eliminated. Weight gain ( p<0.05 ) and feed intake ( p <0.01 ) of the filial chick were significantly reduced when the dam was fed with high calcium diet. Serum alkaline phosphatase activity of the filial chick had greater compensation to zinc levels of the dam diets. High level of calcium in hen diet had no effect on serum alkaline phosphatase activity ( p>0.05 ), but significantly reduced serum protein contents in the filial chick. Tissue zinc contents of the filial chick had greater compensation to zinc levels of the dam diets. High level of calcium in the filial diet had no effect on zinc contents in tissues of the filial chick ( p>0.05 ) .
