EFFECT OF SUMMER AND WINTER AIR TEMPERATURE AND HUMIDITY ON PRODUCTIVE PARAMETERS OF BROILER CHICKENS RAISED IN THE CITY OF LIMA

This study was carried out to evaluate the influence of environmental temperature and humidity on productive performance of Cobb-Vantress 500 broiler chickens reared for 45 days under an open broiler house during the winter and summer seasons (2004). The trial comprised 720 1-day-old chickens (360 chickens per season using 5 repetitions of 34 males and 38 females each). Body weight, body weight gain, feed consumption, feed conversion index, mortality, body size uniformity, and productive efficiency index were evaluated. Weekly body weight and body weight gain were statistically different between birds reared in winter and summer (p<0.05). The higher temperature during summer affected feed consumption, body weight and productive efficiency index but did not affect feed conversion index. The rearing of broiler chickens, both males and females, during the summer season as compared to winter season resulted in 200 and 100 g less per bird of body weight respectively.

Se evaluó la influencia de la temperatura y humedad medioambiental sobre los parámetros productivos de pollos de carne de la línea Cobb-Vantress 500 criados por 45 días bajo el sistema de galpón abierto durante las estaciones de invierno y verano del 2004. Se utilizaron 720 pollos (360 aves por estación, empleándose 5 repeticiones con 34 machos y 38 hembras por grupo). Se evaluó el peso corporal, ganancia de peso, consumo de alimento, índice de conversión alimenticia, mortalidad,uniformidad de peso corporal e índice de eficiencia productivo. Hubo diferencias significativas (p<0.05) entre las campañas de verano e invierno con relación al peso y ganancia de peso semanal. La mayor temperatura en el verano afectó el consumo de alimento, la ganancia de peso y el índice de eficiencia productiva, pero no el índice de conversión alimenticia. La crianza de pollos de carne, tanto machos como hembras, durante la estación de verano bajo sistemas de galpón abierto ocasionó una merma de 200 y 100 g de peso corporal, respectivamente, en comparación con la crianza en invierno.
