RESUMO
Footpad dermatitis (FPD) is a condition that causes necrotic lesions on the plantar surface of the footpads in growing broilers and turkeys. This condition not only causes downgrades and condemnations of saleable chicken paws, the portion of the leg below the spur, but is also an animal welfare concern in both the United States and in Europe.. Revenue from chicken paws in 2008 alone was worth $280 million. Harvesting large, unblemished paws has become a priority to poultry companies all over the world. Research on this subject has been ongoing since the 1940s and has looked into many different areas including nutrition, environment, and genetics. Early research looked at nutritional deficiencies such as riboflavin and biotin mainly in turkey poults. This early research was most likely looking at a separate form of dermatitis than what is being investigated now. Recent findings have suggested that there is a myriad of interacting factors that lead to FPD. Litter moisture appears to be the most likely culprit in the onset of this condition. Research has also shown a possible genetic link in the susceptibility to development of FPD lesions. Current chicken paw prices have skyrocketed due to a large export market in Asia. To produce unblemished paws for both increased profit and comply with current animal welfare recommendations, further research is needed to understand how the condition develops and what strategies can be used to prevent it.
