Evaluación de diferentes programas de iluminación en el rendimiento productivo de pollos de engorde.

Abstract

This research was conducted in the Recinto San Vicente located in the Cantón Cumandá; Chimborazo Province. The research was divided in three chicken coops with 90 chickens per coop; each coop was then subdivided in three cubicles with 30 chickens per cublicle separated by sex; which means 30 males, 30 females and 30 of mixed sex. This resulted in a total of 90 chicken per coop and 270 in total. In each chicken coop there was a different illumination program. The first chicken coop had 23 hours of light, the second one had 17 hours of light in which the lights would be off during two times of 3 and 4 hours each at night; and the third coop was given the illumination program recommended for the Cobb breed. The objective was to evaluate the different illumination programs and their effect on the bioproductive parameters in broiler chickens. The 3 groups were subjected to the same breeding conditions. At the end of the research it was concluded that, even though there’s not significant stadistical difference, the 17 hours illuminations program was the one with the best results considering the bioproductive parameters; when it comes to mortality the three programs had a low mortality, which is beneficial for the production, and when it comes to uniformity all the programs were inside the established range.
