Resumen

The object of this work was to determine dry matter (DM), crude protein (CP), ether extract (EE), crude fiber (CF), ash, metabolizable energy and retention of nutrients of the torula yeast from distiller?s vinasse, for its use in poultry feeding. The torula yeast from vinasse had average value of 43.24 % CPB, 1.60 % CF, 1.20 % EE, and 7.15% ash. There were average values of apparent metabolizable energy (AME) of 2811 kcal/kg, corrected by the nitrogen balance (AMEn) of 2362 kcal/kg and coefficient of metabolization of the energy (CMGE) of 58 %. The apparent retention of the dry matter was 65.20 %, and of 53.81 % for nitrogen and of 63.46 % for total phosphorus. It was concluded that it is feasible to use distiller?s vinasse as basic substrate for the production of torula yeast, by not having differences in the chemical composition and the nutritional value of this protein source; thus, it can be used in poultry feeding.
Key words: yeast, metabolizable energy, retention of nutrients, broiler chickens.
