High ambient temperatures mean detrimental performance and reduced profits for producers. Extreme cases cause suffering and death in all poultry breeds. Phytogenic feed additives in poultry diets help alleviate the negative impacts of heat stress by exerting an anti-inflammatory and antioxidant effect in birds.
Poultry producers commonly face the challenge of heat stress either seasonally or year-round. Poultry farmed in hot and humid countries are genetically derived from strains originally bred in, and selected for, the cool climates of Europe and North America.
Rearing birds outside of their thermal comfort zone could mean failing to achieve full genetic potential. Producers in warmer climates or those in cooler zones who adjust their shed temperatures to their own comfort levels, not to that of their birds, should consider the impact of heat stress on flocks. | READ MORE
