Plantar deficiency of biotin
The presence of Biotin is very important in tissues with rapid mitosis as intestinal epithelia and skin. Although it can be synthesized by intestinal microorganisms, the combination of low doses of biotin and the routine use of antibiotics in feed can cause real biotin deficiencies manifested by intestinal and plantar lesions.
As it is a water soluble vitamin does not accumulate in avian tissues, so its deficiency can manifest from the 5th day of life of broilers. This deficiency leads associated with other risks such as infectious lameness due to increased permeability of epithelia to infections and intestinal malabsorption.
