本试验选湖北白猪双月断奶仔猪36头,以研究基础日粮中添加100PPmZn 和0,10,25,50,75,100PPm 对无机元素吸收和代谢的影响。在试猪36Kg 时进行代谢试验。在4、6月龄时分别采取血清,在3、4、5、6月龄时分别采取毛样。在90Kg 时每组屠宰3头猪并取肝肾肌肉样品。结果表明基础日粮中添加0—50PPmCu 似乎可以促进 Ca 和 Zn 的吸收,但在50—100
In this experiment, we selected 36 piglets of weaned white pigs in Hubei to study the effects of adding 100PPmZn and 0,10,25,50,75,100PPm on the absorption and metabolism of inorganic elements in basal diet. Metabolic tests were performed on 36Kg pigs. Serum samples were taken at 4 and 6 months of age, and hair samples were taken at 3, 4, 5 and 6 months of age respectively. Three pigs were slaughtered in each group and liver and kidney muscle samples were taken at 90 kg. The results showed that adding 0-50PPmCu to the basal diet seemed to promote the absorption of Ca and Zn, but at 50-100
