The response of bobwhite quail to antibiotics


, : The response of bobwhite quail to antibiotics. Poultry Sci 35(1): 76-80

1320 day-old quail were used in 2 experiments to study the response of bobwhite quail to antibiotics. In the 1st, Aureomycin, bacitracin, procaine penicillin G, Terramycin and a streptomycin mixture, were fed to quail chicks for 16 weeks at a rate equivalent to 10 g free base/ton of diet. In the 2d, 3 antibiotics, bacitracin, procaine penicillin G and Terramycin, were fed at 3 different levels equivalent to 5, 10 and 20 g free base/ton of diet, for 6 weeks. Growth response to antibiotic supplementation was variable. Aureomycin, bacitracin, penicillin and Terramycin were highly significantly effective in the 1st experiment, with no significant differences occurring among them at 3 weeks of age. In the 2d experiment, in which neither Aureomycin nor streptomycin was fed, a significantly better growth response occurred with bacitracin and penicillin than with Terramycin. Streptomycin at the 10-g level had no effect on rate of growth. The equivalent of 5 g of procaine penicillin G, 10 g of bacitracin and 20 g of Terramycin produced optimum growth responses. The period of effective growth increase produced by antibiotics varied. In the first experiment, it lasted 3 weeks, while in the 2d experiment, it extended through the 5th week. After the initial 3- or 5-week growth responses, no significant influence on rate of growth was observed in quail that received antibiotic-supplemented diets. The removal of antibiotics at 5 weeks of age had no effect on subsequent per-formance. No significant differences in weight were observed among any treatments at 16 weeks of age. No appreciable effect on mortality was observed as a result of the low level antibiotic supplementation.
