Reusing litter is a common practice in broiler farming. However, it requires the adoption of efficient procedures for inactivating and controlling residual microorganisms during downtime between flocks to ensure sanitary ...
Intestinal and pancreas enzyme activity of broilers exposed to thermal stress
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2003-04-01)
Thirty-two Hubbard broilers were raised under commercial husbandry to evaluate the effect of temperature exposure (26 and 35ºC) on the activity of digestive enzymes at different ages (23 and 46 days) and different ...
Effect of environmental temperature on immune response of broilers
(Poultry Science Assoc Inc, 2003-09-01)
Several studies demonstrate that environmental temperature can influence the immune response of poultry. The objective of this research was to determine at which stage in the life of a bird this effect is greatest. In ...
