Impacto del probiótico Saccharomyces cerevisiae var. boulardii RC009 solo y en combinación con una enzima fitasa sobre los parámetros productivos y bioquímicos en pollos parrilleros

Abstract

The objective of this study was to evaluate the impact of the probiotic Saccharomyces cerevisiae var. boulardii RC009 alone and in combination with a phytase enzyme on the productive performance of broiler chickens fed antibiotic-free diets. A total of 153 of 1-day-old male broilers (Arbor Acres) were stabilized for 7 days, weighed at 7 days, and randomly selected into 3 treatments with 3 replicates each (17 broilers/replicate). During the experimental period (49 days), the broiler chickens received the starter and finisher diet corresponding to each treatment. Treatments (T): T1: basal diet (BD - control); T2: BD + PROBIO SACCH (200 g/T, equivalent to 1 x 1012 CFU/T of food); T3: BD + PROBIO SACCH (200 g/T, equivalent to 1 x 1012 CFU/T of food) + phytase enzyme (1000 FTU/T). The productive parameters of daily weight gain (DWG), daily average consumption (DAC), conversion index (CI), weight of leg, thigh and breast and biochemical parameters were determined. The results obtained showed that the probiotic was able to significantly improve the productive parameters DWG and CI (p ≤ 0.05), compared to the control. Although the probiotic mixed with the enzyme increased DWG significantly, the IC was the same as that obtained with the use of the probiotic alone. The weight of leg-thigh and breast was greater with the presence of the probiotic when compared to the control, and the mixture with enzyme was significantly greater than the weight of the mentioned cuts. The biochemical parameters evaluated were not modified with the addition of the probiotic and/or the enzyme. In conclusion, the use of S. boulardii RC009 only significantly improved the productive parameters studied and did not differ in general from the use in combination with the enzyme. In carcass weight, a significant increase was observed with the probiotic alone and even better when it was used in mixture with the enzyme.
