Field trials to assess the value of a bivalent killed salmonella vaccine in the control of ovine salmonellosis

Extract

The recent interest in the control of salmonella infection in farm livestock by vaccination has been concerned principally with the disease in calves, pigs and poultry and with the use of living attenuated vaccines rather than vaccines using killed organisms. Ovine salmonellosis, perhaps because of its limited importance in countries other than New Zealand and Australia and the sporadic nature of outbreaks, has not figured prominently in the scientific literature.
