摘要
研究不同水平的酵母镧螯合物对小白鼠生长性能的影响。Ⅰ组为空白组(基础日粮组);Ⅱ组为阳性对照组,在基础日粮中添加复合酵母和无机镧50.0mg/kg(以镧含量计算)混合物;Ⅲ、Ⅳ、Ⅴ组为试验组,在基础日粮中分别添加酵母镧螯合物37.5、50.0和62.5mg/kg(以镧含量计算)。结果显示:Ⅲ、Ⅳ、Ⅴ组料重比比空白组分别降低了7.43%(P>0.05)、10.95%(P<0.01)和11.23%(P<0.01)。添加剂量为50.0～62.5mg/kg酵母镧螯合物的效果较好。
This experiment was conducted to study the effect of different supplement level Yeast La Chelate on growth performance of white mice. Yeast-La chelate was supplemented at 0, 37.5, 50.0 and 62.5 mg/kg （based on the La content） in the basal diets of I, The results 11.23%o （Ⅲ , IVandV ; The mixture showed as follows： Feed-g P〈0.01） of yeast powder and inorganic La （50.0 mg/kg basal diet） were added in group II diain ratio of lll, IV and V were decreased 7. 430/00 （P〉0.05） , 10.95% （P〈0.01） of blank group, respectively. Yeast-La chelate level of 50.0-62.5 mg/kg was better
