Uso de acidificante y probiotico en el agua de bebida de pollos broiler

The present research work aims to evaluate three types of treatments, two with additives (probiotic and acidifier) and a control in broiler chickens in order to improve productive parameters. It was carried out at Punzara Experimental House of Universidad Nacional de Loja, two additives (probiotic and acidifier) were evaluated, at early ages (1-28 days) of broiler chickens in order to evaluate live weight, average consumption daily, average daily gain, feed conversion and mortality; 299 one day-old broiler chickens were used, which were housed in experimental units of 10 animals. The trial design was with a repeated measures model. In treatments three and five the supply of acidifier (citric acid) was applied, 1 gr per liter of drinking water. In treatment two and four, 0.80 gr of probiotic was administered. (Saccharomyces Cerevisiae) in 1 kg of food; all treatments covered the requirements of the Cobb 500 genetic line. The animals were sacrificed when they were 42 days old. Variables were compared in a protected t-test. Productive parameters did not have significant differences except for the conversion diet in week five (p=0.033). The highest economic performing treatment was the one that was administered probiotic and control with 25.49% and 24.99 respectively. Concluding that the use of a probiotic and acidifier could be considered as an alternative for the production of broiler chickens from the point of view of economic and health point of view. Keywords: Acidifier, probiotic, treatment.
