MACROSCOPIC AND MICROSCOPIC EVALUATIONS OF THE EFFECT OF BIOTIN ON CLAW HORN QUALITY IN CALVES
Abstract
This study involved in macroscopic and microscopic evaluations of the effects of biotin on claw horn quality and claw horn growth in 20 calves over 6 months in the research and application farm of Veterinary Faculty of Firat University in Elazığ. The effect of dietary biotin supplementation, at a dose rate of 20 mg/d, was investigated in this controlled feeding trial. No differences in horn growth and wear rates were found between biotin supplemented calves and the controls. After 6 months of biotin treatment, the horn quality showed significant improvement. It was concluded that continuous dietary supplementation with biotin at a daily dose of 20 mg is improve and maintain claw horn quality in calves.
