摘要
在产蛋种鸡的日粮中，分别添加１％、２％和３％的膨润土进行饲喂试验。结果表明，以添加１％的效果最佳，与不加膨润土的对照组相比，产蛋率提高２．８３％，料蛋比降低１．１４％，孵化率提高９．０４％，种鸡生产雏鸡的能力提高１１．９５％，生产利润提高１５．２％。添加２％的效果办优于对照组，但差异不显著；而添加３％的效果则不及对照组。
The experiment studied the effect of supplementing bentonite on preductive capacity in chick of producing-egg breeds. Basal ration supplemeted 1%. 2% and 3% bentonite respectively. The result showed that the egg yield was increased to 2.83%, the feed conversion of laying period was decreased to 1.14%, the incubative ratio was increased to 9.04%,the profite of production was increased to 15.2%, comparative as control; the trial result of supplementing 2% bentonite was gooder than control; supplementing 3% bentonite was poor.
