Evaluación del uso de acidificante en el agua y saccharomyces cerevisiae en el alimento de pollos parrilleros sobre su calidad de la canal

Poultry production nowadays seeks to maximize feed consumption in broilers to obtain optimum yields in a shorter time. Offering the consumer a safe product is a challenge; therefore, the inclusion of alternative additives such as immunostimulants and acidifiers is an alternative to reduce the negative impact on the final product. The objective of the present investigation paperwork was the use of acidifier in water and Saccharomyces cerevisiae in the feed of broiler chickens on carcass quality randomly distributed a total of 299 42-day-old Cobb 500 broilers with an average weight of 46.5 g in three treatments: Tl (control), T2 1 g/kg of citric acid in the drinking water and T3 0,80 g/kg of Saccharomyces cerevisiae in the feed. The diets were formulated by the production stage considering the nutritional requirements of Cobb 500. The variables evaluated were carcass yield, pigmentation of tarsus, skin, thigh, and thigh pH. Data were analyzed in the statistical program SAS 2016, using an analysis of variance (ANOVA) and a protected t-test for mean comparison. The results showed no statistical difference for the variables of carcass yield p=0,675, pigmentation in L*tarsus p=0,958, skin p=0,661, thigh p=0,693 and thigh pH p=0,837, but we evidenced a significant difference p=<.0001 in the parameter a* of tarsus pigmentation and a trend p= 0,065 in b*. We conclude that including additives in the diet and drinking water does not influence the variables studied except for tarsal pigmentation in parameter a*. Keywords: yeast, citric acid, carcass yield, pigmentation, pH.
