Evaluation of boldenone as a growth promoter in broilers: safety and meat quality aspects
2016
Abstract The object of this study was to evaluate the safety and meat quality criteria in broilers following intramuscular injection of boldenone. Twenty-four broiler chicks, divided into two groups, were used in the present study. Boldenone was injected intramuscularly at a single-dose level of 5 mg/kg body weight into 12 broiler chicks at 2 weeks old; the other 12 chicks were injected with sesame oil and kept as controls. Blood samples were collected from the wing and metatarsal veins after 1, 2, and 3 weeks through the experimental course for hematological and clinic-chemical safety parameters. On the last day, chicks were humanely sacrificed and livers and kidneys were removed for histopathological examination. Breast muscles were also removed to assess meat-quality parameters. Boldenone significantly ( p p p p
