The effect of exogenous proteases on selected hematological and serum biochemical parameters in boars.

The increasing interest in enzymatic growth promoters prompted this investigation of the effect of an enzymatic stimulating complex on selected hematological and serum biochemical parameters in boars. The enzymatic complex [five proteases (proteinases-endopeptidases) and two peptidases (exopeptidases) obtained by fermentation from Streptomyces fradiae] was added to diets for three months, at initial doses of 90 (group E1) and 120 (group E2) g/ton feed for the first seven days followed by 40 and 60 g/ton, respectively, in the subsequent weeks. The evaluation was based on selected hematological (RBC, WBC, HCT (Ht), HGB (Hb), MCV, MCH, and MCHC) and biochemical (AST, ALT, AP, Ca, Mg, urea, cholesterol, creatinine, inorganic phosphorus, and oxyglucose) parameters determined before and after the experimental period.

Evaluation of the degree of pancreas activity in piglets from sows fed enzymatic stimulating complex.

One of the possibilities for estimating pancreas activity is the estimation of zymogene granule content in pancreatic follicular cells. In the present study, the degree of pancreatic activity was measured in piglets from sows receiving enzymatic stimulating complex throughout pregnancy and during the lactation period. The pancreas was collected for ultrastructural examination from 1-day-old and 21-day-old piglets.
