Resumen
El objetivo de esta investigación fue evaluar el efecto del aditivo Saccharomyces cerevisiae en el comportamiento productivo, porcentaje de mortalidad e índice de diarreas en becerros lactantes. Se utilizaron 40 terneros de cruces Gyrolando, y Jersey con Gyrolando, con 7 días de edad y 37,78 kg de peso inicial. Los animales se asignaron al azar en dos grupos de 20 animales cada uno (experimental y control). Los animales se alimentaron con forraje fresco, alimento balanceado y leche. El aditivo se suministró disuelto en la leche, dos veces al día (06:00 am y 18:00 pm), al grupo experimental. No se obtuvieron diferencias en el peso vivo acumulado, ni la ganancia media diaria de peso vivo. Sin embargo, el peso vivo (PV) final ganado del grupo experimental fue superior (p˃0,10), con 78,45 kg de PV, respecto al control (70,70 kg). Se observó 5% de incidencia de diarrea en el grupo experimental y 40% en el control. El aditivo no influyó en la ganancia promedio diaria de PV de los becerros lactantes, pero redujo la incidencia de diarreas.
The objective of this research was to evaluate the effect of the additive Saccharomyces cerevisiae in the productive behavior, mortality rate and rate of lactating diarrhea in calves. 40 calves were used. The races were Gyrolando and Jersey crosses with Gyrolando. The animals were 7 days old and 37.78 kg initial weight. The animals are randomized into two groups of 20 animals each one (experimental and control). The animals were fed with fresh forage, balanced food and milk. The additive is supplied dissolved in the milk, twice per day (6:00 a.m. and 6:00 p.m.), the experimental group. No differences in body weight accumulated or average daily live weight gain were obtained. However, body weight (BW) Final won the experimental group was higher (p˃0,10) with 78.45 kg BW, compared to the control (70.70 kg). 5% incidence of diarrhea in the experimental group and 40% in the control was observed. The additive did not affect average daily gain of PV lactating cows, but reduced the incidence of diarrhea.
