Response of guinea fowl (Numida meleagris) to dietary supplementation of zinc bacitracin.
The effect of dietary bacitracin on the growth and feed conversion of guineas has been investigated using graded levels of the antibiotic. The treatments were 0, 11, 22, and 45 mg bacitracin/kg diet. Poorest live weights were recorded by unmedicated guineas. Keets given bacitracin at 11 mg/kg recorded significantly higher live weights (P less than .05) than unmedicated chicks. Best live weights were obtained at a supplementation level of 22 mg/kg; supplementation to 45 mg/kg gave no further growth improvement.
