Change of pig femoral macromometry indices under the influence of mineral additives

The aim of our research was to study the effect of feeding additives zeolite (marl) Ulyanovsk region on bone morphometry indicators in pigs. For experiment piglets of large white breed which were divided into three groups were selected. Piglets of group 1 (control) received the main diet, 2 groups (experience with polysols) received additional polysols (0,6 mg per 1 kg of weight). Piglets of group 3 (experience with zeolite) were fed the main diet with the addition of 2 % zeolite from dry matter, which corresponded to the level of copper, zinc, manganese, cobalt in the diets of piglets receiving polysols. The inclusion of mineral supplements in the diet contributes to the positive dynamics in the bone tissue of pigs. By the end of fattening, the index of absolute femoral massiveness in pigs of group 3 was 8,54 % (P
