The effect of a multi-microelement preparation on the digestive enzyme activity of broiler chicken. Preliminary publication

Hybro N day-old broiler chicken were assembled into a control and an experi mental group. Both group consisted of 50 birds of random sex. From day 1 on ward 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 alpha -amilase, lip ase, tripsin and total-protease activity was measured in the juice of the s mall 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 c arcase weight and the killing-out percentage showed improvement in comparis on with the control, however, the difference was statistically not signific ant. Lipase activity of the pancreatic homogenates from experimental male b roilers proved to be significantly (P <0.01) higher than that of the contro l cocks. Both male and female experimental birds had an increased pancreati c tripsin activity (P <0.01 and P <0.05). Amylase activity of the intestina l juice in experimental female and male broilers was over that of the contr ols (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, respecti vely).
