The TS in the feed stored in the refrigerator for up to 5 days is stable; however, the TS partially degrades at elevated temperatures in the animal room. The analyses displayed that the lower the initial test concentration, the greater the degradation.

Description of key information
Results from toxicity studies on mallard duck (Anas platyrhynchos) and bobwhite quail (Colinus virginianus) demonstrate that C(M)IT/MIT exhibits slight to moderate toxicity to birds. The acute oral LD50for bobwhite quail is 460.72 mg/kg bw (equivalent to 64.5 mg a.i./kg bw) and the LD0 is 153.57 mg/kg bw (equivalent to 21.5 mg a.i./kg bw) . The short term dietary LC50 for mallard duck is 945 ppm a.i. and bobwhite quail is 3536 ppm a.i. . The NOEL and LC0 for the short-term dietary study with mallard duck was 226 ppm a.i. The LC0 for the short-term dietary study with bobwhite quail was and 1450 ppm a.i.
