title: [Effect of Bulgarian potassium-calcium zeolites on the assimilation of macro- and trace elements in lambs].
abstract: Experiments were carried out with 12 test and 6 control male lambs from weaning at 20 days of age up to the 65th day. Both groups were kept under equal conditions. The test lambs were given their basic ration plus 4 per cent of a Bulgarian potassium-calcium zeolite. It was found that the treatment of lambs with a zeolite did not lead to changes in the dry matter content, the fats, and the crude protein in the analyzed fractions: carcass head, viscera, and digestive apparatus. There was, however, an increase in the ash. It was also established that the test lambs deposited higher amounts of Ca, P, Mg, and Zn in the parts referred to. The addition of 4 percent zeolite resulted in the increase of the average daily gain by 19.3 per cent.
