Última Climatic Variation: Effects on Stress Levels, Feed Intake, and Bodyweight of Broilers Rev. Bras. Ciênc. Avic. Osti,R; Bhattarai,D; Zhou,D. ABSTRACT Chickens tolerate a very narrow range of climatic variation, and therefore, it is essential to determine the most suitable climatic area and weather for broiler production in open-house systems. In this study, 3060 broilers were used as experimental birds to investigate the effects of seasonal differences and climatic variations on the growth performance of broilers reared in an open-house system. Birds were kept under various treatment models that differ in climate Tropic zone, sub tropic zone and temperate zones. Data were recorded during July-August as summer months and January-February as winter months. Collected data was analyzed using the least square procedure given by Harvey-1990. Significantly higher (p<0.05) level of corticosteroids... Tipo: Info:eu-repo/semantics/article Palavras-chave: Broiler production; Climatic variation; FCR; Open housing system; Stress level.
