Sažetak
The aim of this research was to determine influence of dietary supplementation with thermolysed Brewer’s yeast enriched by dietary nucleotides (Ascogen®) on growth performance, blood parameters and stress reduction in fattening lambs. Biological research was conducted on 32 lambs in fattening during 50 days. Lambs were at the age of 60 days. Thermolysed Brewer’s yeast (1.5%/DM) was added to the feed mixture of experimental group of lamb. In the lambs´ blood serum biochemical parameters, enzymes activities, thyroid hormones (triiodothyronine-T3 and thyroxine-T4), and cortisol concentrations were determined. Application of thermolysed Brewer’s yeast does not affect the growth of lamb, although better average daily gain of lambs (4.31% higher) in the experimental group was determined. Decreased (P<0.05) concentrations of calcium, iron and alanine aminotransferase activity were determined in experimental group of lambs, compared to the control group, as well as significant increase of γ-glutamyl transferase, alkaline phosphatase and thyroid T3 hormone activity. Slightly lower concentrations of cortisol was found in experimental group of lambs compared to the control (40.16:47.57 nmol/L), but differences were not significant (P=0.33). Determined minor improvements in growth performances and blood parameters changes of lambs indicate slightly anti-stress effect of dietary supplementation with yeast.
