Efecto de la inclusión en la dieta del probiótico Sorbifauna sobre el crecimiento posdestete de ovinos estabulados Effect of the inclusion of the Sorbifauna probiotic in the diet of confined weaned sheep

y 49,7-53,0 g de MS/kg de PV 0,75 para cada indicador; mientras que el consumo de paja de frijol fue superior en los animales que recibieron Sorbifauna respecto al grupo control. Se concluye que la inclusion del probiotico Sorbifauna incremento la GMD y el consumo de paja de frijol en ovinos en crecimiento posdestete estabulados, sin que se afectara el consumo de CT-169. Palabras clave: consumo, ganancia de peso, Pennisetum purpureum AbStRAct: A study was conducted with 36 confined weaned Pelibuey sheep, in order to evaluate the effect exerted by the inclusion of the Sorbifauna probiotic on the live weight (LW) gain and the rough- age intake. Four homogeneous groups of nine animals each were formed according to their LW, and were fed with a basis diet composed by Pennisetum purpureum clone CT-169, bean straw and concentrate feed; water and mineral salts were offered ad libitum. The treatments were constituted by three doses of probiotic: T1: 20 g/animal/day, T2: 30 g/animal/day and T3: 40 g/animal/day, and a control without probiotic (T4). The final LW did not show significant differences among the treatments (18,28; 18,43; 18,20 and 17,23 kg); however, the mean daily gain (MDG) did differ and was higher in the animals that consumed probiotic (130,0; 135,8 and 135,4 g/animal/day) with regards to the control (112,6 g/animal/day). The intake of CT-169 did not show variation among the treatments, with values that varied between 255,3 and 273,4 g green matter/kg LW 0,75 and 49,7-53,0 g DM/kg LW 0,75 , respectively; while the bean straw intake was higher in the animals that received Sorbifauna with regards to the control group. It is concluded that the inclusion of the Sorbifauna probiotic increased the MDG and the bean straw intake in confined growing sheep, without affecting the intake of CT-169.
