Effect of T-2 toxin and antioxidants on angel wing incidence and severity in White Roman geese

This study investigates the effects of T-2 toxin and antioxidants on the incidence and severity of angel wing in White Roman geese. Twelve pens were used in this study, and half of them received dietary supplementation of T-2 toxin (10 ppm) and antioxidants (vitamin C 1000 ppm plus Se 0.3 ppm). Each pen contained birds from the normal wing line (NL), the selected angel wing line (AL), and a controlled commercial line (CL). The results showed that there was no significant difference in the body weight, body weight gain, and feed intake of goslings that were supplemented from birth to 6 weeks of age with T-2 toxin and antioxidants. The alkaline phosphatase level in the T-2 toxin group was lower than that in the control group at 4 and 6 weeks. The haemoglobin level in the T-2 toxin group was lower than that in the control group at 6 weeks. There was a significant interaction between T-2 toxin and antioxidants in the severity score of angel wing (SSAW) and incidence of angel wing (IAW) at 6 weeks. In conclusion, the results suggest that a diet supplemented with T-2 toxin does reduce alkaline phosphatase levels. When the diet contained T-2 toxin and antioxidants, the SSAW and IAW increased.
