Abstract
The influence of brewers yeast on production results was investigated
on 162 Ross 308 broilers Chickens were divided according to sex and
according to protein source in feed. Control groups were fed commercial feed mixtures containing fish meal, soybean meal and sunflower meal in starter and soybean meal and sunflower meal in finisher. Experimental groups were fed commercial feed mixtures containing brewers yeast, soybean meal and sunflower meal in starter and finisher as a protein source. Body mass, body mass gain, feed conversion ratio, health status, mortality and carcass characteristics were investigated during 42 days of the experiment. Results showed that there were no significant differences
between control and experimental group of the same sex. We concluded that brewers yeast could replace protein of animal origin in feed mixtures for fattening chickens.
