Abstract

Three experiments were conducted to evaluate the effects of seasons (cold hot and wet) and energy levels of diets on the performance of broiler chickens. In the first experiment, 198 birds were used. In the second experiment, 144 birds were used, while, 216 birds were used in the third experiment. The birds were fed the same type of diets during the three seasons. The diets fed were iso-nitrogenous but not iso-caloric, having 3000, 2800 and 2600 ME kcals /kg energy levels, while the crude protein levels was 20%. There was a significant (P< 0.05) difference across the three seasons in terms of ambient temperature, relative humidity and rainfall. And also, significant (P< 0.05) differences existed in the general growth performance and carcass characteristics of the birds. However, the rectal temperatures varied significantly (P <0.05) in relation to the ambient temperature during the three seasons (41.35, 20.400C) during the cold, (41.87, 30.500C) for the hot and (41.47, 25.200C) for rainy season, rectal and ambient temperatures respectively. There was a significant (p< 0.05) differences across the three seasons in terms of final weight, weight gain, feed intake, feed to gain ratio and water intake and feed cost per kg gain (N). It was therefore concluded that the climatic factors (temperatures, humidity and rainfall) have influence on the general performance of broiler chickens.
