An experiment with a factorial arrangement of treatments was conducted using five levels of dietary calcium and two levels of zeolite A. When dietary calcium was deficient or marginal, zeolite A improved calcium utilization, as evidenced by improved growth rate and a reduction in rachitic lesions. There was little benefit from adding zeolite A to diets adequate in calcium. The effect of zeolite A on the incidence of tibial dyschondroplasia was inconsistent.
采用析因处理安排进行了一项实验，使用了五个水平的日粮钙和两个水平的沸石A。当日粮钙缺乏或处于边缘水平时，沸石A提高了钙的利用率，这表现为生长速率提高和佝偻病病变减少。在钙充足的日粮中添加沸石A几乎没有益处。沸石A对胫骨软骨发育不良发病率的影响并不一致。
