Effect of the substitution of soybean meal by dehydrated yeast (Saccharomyces cerevisiae) as a protein source in diets for weanling piglets on the intestinal digestive enzymes
The effects produced by the substitution of the crude protein (CP) of the soybean meal (SBM) by CP of the dehydrated yeast in "spray dry" (DYSD) on the morphology of the small intestine mucosa and the activity of the intestinal digestive enzymes was studied. For this purpose, 60 weaned piglets twenty one days old were distributed according to a design of blocks at random with factorial arrangement 5x4 (5 substitution levels: 0, 25, 50, 75 and 100 % of SBM crude protein by DYSD crude protein in the diet x 4 periods of time: 0, 4, 8 and 12 days after the weaning). The DYSD in the diet only did cause a reduction of the intestinal villi size in the first segment of the small intestine, promote a lineally increase in the activity of the sacarase and maltase, and at the same time the dipeptidases showed a quadratic response.
