Chukar partridges were fed diets containing 1.25, 2.5, or 5 ppm aflatoxin; 1, 2, or 4 ppm ochratoxin A (OA); or 4, 8, or 16 ppm T-2 toxin. Toxin-induced mortality was seen during the third week with 4 ppm OA (12.5%) and 16 ppm T-2 toxin (15%), compared with the mortality in control chukars fed no toxin (2.5%). Body weights were significantly decreased by the highest level of aflatoxin at 3 weeks of age, by the highest level of OA by 2 weeks of age, and by 8 and 16 ppm T-2 toxin by 1 week of age. Aflatoxin did not affect liver weight and OA did not increase kidney weight in 3-week-old chukars. There was a slight decrease in kidney weight in chukars fed 4 ppm OA; however, the decrease was related to the decrease in body weight produced by the toxin. Mouth lesions were seen at all levels of T-2 toxin fed.
