I've read a few articles on the pros & cons of giving pigeons electrolytes after a race, some vets say its a waste of time and in fact you are doing more harm than good by administering them after a race. Their argument is that pigeons don't lose salts as they cant 'sweat'. By giving them electrolytes after the race you are overloading their body's with salts, doing the reverse of the desired affect your after.
