Abstract: | 1. The effect of either procaine penicillin or zinc bacitracin (25 mg active base/kg food) on the response of young birds to three different stressors - withdrawal of food for 18 h, exposure to cold for 24 h or treatment with ACTH- has been examined. 2. Neither antibiotic had any consistent effect on the stress responses. 3. It is concluded that neither penicillin nor bacitracin has any stress-ameliorating activity at least under the conditions of the test. |
