Resistant Salmonellosis in Southern Alberta Feedlots

Abstract

Death losses were normally between I% and 2% but with the advent of salmonellosis, losses increased to between 2% and 2½%. In addition there were increases in cattle prices, in interest rates and in feed costs. Veterinary services and drugs became expensive and many treated animals developed chronic sicknesses. Finally, there was concern over the possibility of investigation by public health authorities. Losses continued at a lower level throughout the summer and fall of 1979 but rose to a second peak during the winter. Losses then gradually decreased in the spring of 1980 and finally stopped during midsummer.
