Effects of enrofloxacin and marbofloxacin administration on some fertility parameters of male chicken

The effect of oral administration of enrofloxacin and marbofloxacin at doses of 10, 20 and 40 mg/kg body weight on sperm traits, secondary sex characters and some metabolites in male chicken was investigated. No difference between normal motility and defect sperm in control, enrofloxacin or marbofloxacin treated birds. Weight of walttles and combs were not affected by quinolones. Testosterone, ascorbic acid, total protein and cholesterol concentration were similar in control, enrofloxacin or marbofloxacin treated groups. It is suggested that enrofloxacin and marbofloxacin at doses used were safe in male chicken.
