在含锌量为30.89PPm,含硒量为0.023PPm 的基础日粮中,添加一定水平的锌和硒,观察对羔羊生长和血清碱性磷酸酶活性的影响,并进行了比较研究。供试羔羊为24只,经健康检查、驱虫后随机分为四组,其中一组为对照组,其余三组分别为添加锌组(加100PPm 锌),添加硒组(加0.2PPm 硒),添加锌、硒组(100PPm 锌+0.2PPm 硒)。试验期为35天。结果发现:添加100PPm 锌组的羔羊增重比对照组有极显著
In the basal diet containing 30.89 ppm zinc and 0.023 ppm selenium, some levels of zinc and selenium were added to observe the effects on the growth and serum alkaline phosphatase activity of lambs and the comparative studies were carried out. Twenty-four lambs were randomly divided into four groups according to the health examination and deworming. One group was control group, the other three groups were adding zinc group (plus 100ppm zinc), adding selenium group (plus 0.2ppm selenium) , Add zinc, selenium group (100PPm zinc + 0.2PPm selenium). The test period is 35 days. The results showed that the weight gain of lambs supplemented with 100ppm zinc was significantly higher than that of the control
