Potencialidad del Uso de la Levadura Torula Desarrollada Sobre Vinasa de Destilería para Cerdos en la Etapa de Crecimiento

Abstract

In the productive pig unit of the Animal Science Institute (ICA), in the Municipality San José of Lajas. La province – Cuba, the productive parameters of cross-bred pigs (Yorshire x landrace x Durac) in the growth stage were determined. 24 pigs with an average weight from 25.44 to 26.19 kg, were used; each animal represents an experimental unit, under a completely at-rendom desing with three treatments of torulus leaven levels (0, 33 and 66%) and 8 replications. In the growth stage, the studied variables did not show any significant differences between the treatments such as initial weight, final weight, total weight gain, daily weight gain, total feed consumption, DM feed consumption /day total raw protein consumption, Ms feed conversion, and protein conversion. The bnefit-cost index enhanced the tratment of 66% with 1,56 which means that per each invested dollar there is a 0.56- USD profitability. It is recomended the addition of leaven torulus in feeding diets, containing 66 % protein provided by it as a substitute of the soybean protein in pig feeding as the levels do not affect the pig pro ductive bahaviour.
