The Use of Gallamycin for Controlling Infectious Atrophic Rhinitis in Bacon Pigs.

The use of Gallamycin to control nasal deterioration and permit increased growth rates in bacon type pigs was studied. Litters were randomly divided according to sex into treatment and control groups. Animals were treated by injection with 2.5 mgm of Gallamycin per pound liveweight at weekly intervals commencing during the first through the fifth week of age. Treatments ceased during the eighth week of age. Gallamycin treatment did not reduce significantly the percentage of nasal turbinate degeneration nor increase the rate of gain per day of treatment compared with control animals within litters. Possible explanations of results obtained are hypothesized.
