Amstutz, professor of veterinary medicine at Purdue University told scientists attending the 27th Annual Pfizer Research Conference here this week. Reviewing research conducted in 1978 on respiratory diseases of cattle, Amstutz said the real killer of cattle continues to be pasteurella. Although numerous drugs “have been widely used to treat respiratory disease, they often have not been used 28” CONTROL WEEDS IN ALFALFA WITH BUTYRAC-200 Apply 2 to 4 weeks after alfalfa emerges. Controls broadleaf weeds in seedling or established legumes. This remarkable selective action killing many broadleaf weeds without affecting certain broadleaf crops has been proven by research men and comm* ercial growers throughout the country.

Research in the past year focused on drug incompatibilities and their effect on laboratory tests as well as bacterial resistance to commonly used antibacterial compounds. Studies on interferon and other agents as antiviral weapons promise to receive much emphasis in future years, Amstutz noted. In 1978, reseachers also in vestigated the stimulation of cell mediated immunity when the system has been depressed. Amstutz said that although more effective vaccines and medicines will decrease the loss of cattle from respiratory diseases, current breeding, feeding, housing, and management practices must be changed if the problem is to be solved in the feedlot and calf bam. Research on herd health programs for the prevention and control of bovine respiratory diseases were also evaluated.
