The objective of this research was to evaluate the performance, carcass yield and intestinal morphometry of broiler chickens raised under different temperatures that received feed with or without yeast extract and prebiotic in the pre-initial phase. One thousand four hundred and forty one-day old male chicks were used, raised in different climate chambers. Feed with or without the addition of yeast extract and prebiotic was offered only in the pre-initial phase (1 to 7 days). From the eighth day on, […]
