Bumble foot

[HollyDuckFarmer]

I was reading "Avian medicine: principles and application" by Ritchie, Harrison, and Harrison about giganmin A. They suggest humbledoot may be related to hypovitaminosis A. I checked the NRC recommendations for ducks and chickens. At all ages ducks have higher requirements (4000 iu for breeding ducks vs 3000 iu for laying hens), suggesting chicken diets might be low in but A. In "Nutritionand management of ducks" by Scott and Dean, they suggest a sort with 8000 iu, and refer to ducks being poor at converting carotene precursores in alfalfa meal, needing pre-formed but A. So perhaps increasing vit A should be included in bumblefoot treatment.
