Evaluación de promotor de crecimiento (Saccharomyces cerevisiae) en la alimentación de pollos broilers de la línea Cobb 500.

Abstract

The present investigation was carried out in the poultry Gran Pollo located in the Chaguarpamba canton, Santa Rufina parish. The analysis carried out was carried out on a total of 360 chickens of the COBB 500 line, the same ones that for a more effective research process were separated into males and females from the beginning of the procedure for the 2 treatments carried out with their respective repetitions. It is worth mentioning that the 2 specified treatments correspond to the Control Treatment (TT) that is composed without a growth promoter, and the second, Treatment 1 (T1) that corresponds to a treatment with a growth promoter in a single dose of 1 kilo per ton of food. In this regard, for each group of chickens an amount of 90 male and 90 female chickens was established, resulting in 3 repetitions for each sex. It is important to mention that the feed used to feed the chickens of the COBB line was distributed in 3 phases: initial, which goes from day 0 to day 8 of age; growth, which goes from day 9 to day 21 and finally the fattening phase, which goes from day 22 to 42 days of age. The main objective was to evaluate the response of the growth promoter Saccharomyces cerevisiae. At the end of the analysis carried out, it was concluded that, despite the fact that there is no significant difference in the procedures carried out, the T1 treatment was the one that gave the best results with respect to the TT treatment.
