Sažetak
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 on feed 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% Progut® in the feed mixture, during the whole experimental period. Body weight, haematological and some biochemical parameters were determined 7th, 21st and 35th day of the trial. No significant differences were determined in average body mass and concerned biochemical parameters (glucose, creatinine, triglycerides, total protein, albumin, globulin, haptoglobin, C-reactive protein). Total leukocytes count was higher (P>0.05) in the experimental group (E) 21st and 35th day, but significantly higher (P<0.01) share of lymphocytes. We found positively strong correlation between total protein and globulin (r=0.86) in the experimental group, and strong positively correlation (r=0.84) between total protein and albumin in the control group. Significantly (P<0.05) strong negative correlation between triglyceride and total protein concentration (r=-0.83), and triglyceride and globulin concentration (r=-0.90) were determined in the experimental group of piglets. Dietary addition of hydrolyzed brewery yeast influenced both cellular and humoral immune response.
