Evaluation of antibiotics for racing pigeons (Columba livia var. domestica) available in The Netherlands.

Antibiotics and chemotherapeutics marketed for use in racing pigeons (Columba livia var. domestica) were evaluated by comparing the dosages and indications given by the manufacturers with the data obtained by pharmacokinetic, bacteriological and efficacy studies. This comparison showed that only three of the recommended dosages and indications of the 60 formulations marketed in The Netherlands are scientifically sound and in accordance with the literature. It is to be expected that the majority of the antimicrobials for pigeons will not satisfy the requirements for final registration as a pigeon therapeutic under the Dutch Veterinary Medicines Act of 1985. Several factors affecting drug availability are discussed, such as the different routes of administration and the influence of food. The public health aspects of the consumption of medicated pigeons is also discussed. Although there is no legislation with regard to this subject, a recommended withdrawal time of 10 days for the majority of the antimicrobials seems advisable.
