The frequency and proportion of Canadian defined daily doses for animals (DDDvetCA) that were larger, smaller, or equivalent to their corresponding defined daily dose for animals (DDDveta), by species and route of administration.
| Species | Route of administration | DDDvetCA:DDDvet Ratio >1.1 N (%) | DDDvetCA:DDDvet Ratio <0.9 N (%) | DDDvetCA:DDDvet Ratio ≥ 0.9 and ≤1.1 N (%) |
|---|---|---|---|---|
| Poultry | Feed | 1 (17) | 5 (83) | 0 (0) |
| Poultry | Water | 4 (31) | 6 (46) | 3 (23) |
| Pigs | Feed | 0 (0) | 11 (100) | 0 (0) |
| Pigs | Water | 5 (29) | 7 (41) | 5 (29) |
| Pigs | Injectable | 5 (29) | 6 (35) | 6 (35) |
| Pigs | Bolusb | 2 (33) | 3 (50) | 1 (17) |
| Poultry and pigs | All routes of administration | 17 (24) | 38 (54) | 15 (21) |
DDDvetCAs were considered larger when the ratio of the DDDvetCA/DDDvet was larger than 1.1, smaller when the ratio was <0.9, and equivalent when the ratio was equal to or between 0.9 and 1.1.
