摘要：
The aim of the study was to determine the influence of the addition of autolyzed brewer's yeast on the productivity and the health status of weaned pigs. A scientific and economic experiment was conducted at the Agricultural Institute - Shumen with 2 groups of 21 pigs in each group, or a total of 42 weaned pigs of the Danube white breed. The pigs were reared in raised pens of 7 pigs in a pen, 3 pens in a group. The animals were equalized by live weight, sex and origin. The experiment started at 9.385-9.464 kg of live weight and ended when it reached 28.95-30.786 kg. In the compound feed of the pigs in the experimental group, the 3% of the soybean meal was replaced with added autolyzed brewer's yeast. The inclusion of autolyzed brewer's yeast (replacing 3% of soybean meal in the compound feed) in weaned pigs (9.385- 9.464 kg to 28.95-30.786 kg lw) of the Danube White breed indicated a tendency for higher daily gain by 8.82% and lower feed conversion ratio per kg gain by 6.93%. Addition of autolyzed brewer's yeast leads to optimization of lipid metabolism and changes some hematological parameters within physiological reference values.
