EFFICIENCY OF HYDROLYZED BREWERY YEAST (PROGUT®) IN WEANED PIGLET’S DIET

Two groups of weaned piglets (N=46), crossbreed (SLxLW) x Pietrain, the same sex proportions, aged 28 days were involved in the investigation. Piglets from all groups were fed mixture for weaned piglets with 22% of crude protein and 13.84 MJ ME/kg until 21st day of the trial and with 19% of crude protein and 13.74 MJ ME/kg until 35th day of the experiment. The experimental group was added 0.2% nProgut® in the feed mixture, during the whole experimental period. Body weight,haematological and some biochemical parameters were determined on the 7th, 21st and 35th day of the trial. No significant differences were determined in average body mass and biochemical parameters (glucose, creatinine, triglycerides, total protein, albumin, globulin, haptoglobin, C-reactive protein) concerned. Total leukocytes count was higher (P>0.05) in the experimental group (E) 21st and 35th day, and significantly higher (P
