An experiment was conducted to ascertain if supplementing a completely purified diet with tin, vanadium chromium and nickel would enhance chick performance between hatching and 27-days posthatching. No effects on rate and efficiency of gain or on feather development were noted. A level of 350 p.p.m. magnesium, all in inorganic form, was found adequate for chick growth during this period.
进行了一项实验，以确定在完全纯化的日粮中添加锡、钒、铬和镍是否会提高雏鸡出壳至出壳后27天的生长性能。未观察到对增重速度和效率或羽毛发育有任何影响。结果发现，在此期间，350 ppm的镁（全部为无机形式）水平足以满足雏鸡生长需求。
