Estudio comparativo de dos métodos de reutilización de cama en la crianza de pollos de engorde.

Abstract

The research was carried out in order to evaluate the bio-productive parameters comparing the methods of alkalinization and fermentation in the reuse of litter in broiler rearing. An experimental design was applied using 540 broilers in the Tres Cerritos Enclosure, Naranjal, they were divided into three blocks of 30, females, males and mixed with three replications. Registration sheets were used as an instrument for 38 days to evaluate the bioproductive parameters, a daily control of the physical parameters and a microbiological sampling were carried out before, during and at the end of the experiment. The results in the evaluation of bioproductive parameters did not show significant differences between the two treatments, a p-value of less than 0.0001 was obtained. Both alkalinization and fermentation were suitable for litter reuse in broiler rearing, the mortality percentage was relatively low with a value of 7.78 %, humidity was maintained between 25 % and 35 %, the temperature was 30 °C and the pH between 7 and 9, the analyses showed absence of Salmonella sp. E. coli, fungi, yeasts and mesophiles remained below reference values.
