Actividad probiótica de Saccharomyces Cerevissiae, en indicadores productivos de pollos ross 308
We evaluated the probiotic activity of Saccharomyces cerevisiae on production and health parameters of 240 Ross 308 chickens from the fifteen days old, with an average weight of 273.84 g were randomly divided into four treatments: control and three levels of probiotic: T1 = 0 g, T2 = 1 g, 2 g T3 = T...

添加标签 | 总结: | We evaluated the probiotic activity of Saccharomyces cerevisiae on production and health parameters of 240 Ross 308 chickens from the fifteen days old, with an average weight of 273.84 g were randomly divided into four treatments: control and three levels of probiotic: T1 = 0 g, T2 = 1 g, 2 g T3 = T4 = 3 g of S. cerevisiae added per kg of food, isoenergetic diets that were isocaloric and provided in three phases: from day 15 to 28, day 29 to 35 and day 36 to 42, when they were slaughtered. From the fifth week, significant differences (P <0.05) between treatment four and the remaining treatments in live weight, weight gain partial and cumulative weight gain. There were no significant differences (P> 0.05) on feed intake, feed conversion and mortality among treatments. We conclude that the inclusion of 3 g kg of S. cerevisiae kg-1 diet significantly improved weight gain in Ross 308 chickens. |
