Enzymatic complex in simple diets on the serum parameters and intestinal morphology of piglets

Abstract

The aim with this study was to verify the effect of the addition of enzymatic complex levels in corn-soybean meal diets on piglet serum parameters and intestinal morphology at 49-day post-weaning. Forty homogeneous male and female piglets, from the same lineage, were distributed in a randomized blocks design, with four treatments and five replicates. Two piglets (male and female) were considered as an experimental unit. The treatments were levels of enzymatic complex: 0, 0.02 (recommended by the manufacturer), 0.04 and 0.06%. Pigs were slaughtered at 70 days old. There was a reduction (P <0.05) in urea and total protein content in blood serum of pigs receiving enzymatic supplementation. The animals that consumed diets with enzyme addition presented a linear increase (P <0.05) on villus heigh (HV) at duodenum segment, linear reduction (P <0.05) on crypt depth (CD) of jejunum and better HV/CD ratio (P <0.05) in jejunum and ileum segments.
