Hybro N day-old broiler chicken were assembled into a control and an experimental group. Both group consisted of 50 birds of random sex. From day 1 onward the drinking water of the experimental group was added (0.10 ml/bwt kg) a multi-microelement preparation (Galli-Stibol) that contained B, Co, Cu, Fe, Mn, Ni, Se, V, and Zn in complex bonds. On day 49 of rearing 7 female and 7 male broilers from each group were killed and the α-amilase, lipase, tripsin and total-protease activity was measured in the juice of the small intestines and homogenate of the pancreas. The rest of the groups were slaughtered in a poultry slaughterhouse. As effect of the multi-microelement preparation the slaughter weight, hot carcase weight and the killing-out percentage showed improvement in comparison with the control, however, the difference was statistically not significant. Lipase activity of the pancreatic homogenates from experimental male broilers proved to be significantly (P<0.01) higher than that of the control cocks. Both male and female experimental birds had an increased pancreatic tripsin activity (P<0.01 and P<0.05). Amylase activity of the intestinal juice in experimental female and male broilers was over that of the controls (P<0.01). Tripsin and total-protease activity of the intestinal juice was enhanced only in the experimental cocks (P<0.01 and P<0.001, respectively).).
