Özet

The aim of this experiment was to evaluate the yeast on fattening performances of the growing cattle. The experiment was carried out with 179 imported 12-14 months old growing different breed bulls (Hereford, Angus, Brangus, and some other crossbreds) that were allocated to control and yeast group according to the breeds and body weight. Experimental diet was formulated with 19 % roughages (alfalfa and wheat straw) containing 13% crude protein. Yeast group was supplemented 40g d-1 live yeast containing 1.23×1011 CFU/g. The study lasted 62 days from May to July. Initial body weight were 393.91±4,43 for control and 395.56±4.45kg for yeast group. After test period, daily gain was similar (1465.85±26.76 vs. 1451.42±34.05g d-1, P>0.05) for the bull receiving the diet without yeast compared to the bulls receiving yeast. Similar results were obtained for feed to gain ratio (P>0.05) as well. In conclusion, under present experimental condition (high concentrate, buffer usage and better total mixed ration management) the yeast (Saccharomyces cerevisiae) did not improve fattening performance of growing cattle.
