Canadian researchers pursue novel vaccines for Johne’s, bovine TB

Infectious diseases continue to be a leading cause of sickness and death in livestock and are of concern to human health due to their potential to be transferred to people. Vaccination is the most cost-effective means of preventing infectious disease in animals and humans, but its application to livestock is still limited, and the lack of effective vaccines contributes to the excessive use of antibiotics in animal health.


Boxed Beef Report: Beef prices up slightly

Collaboration key to antibiotic stewardship

Human and animal health experts came together in Atlanta, Georgia Nov. 3-5 to discuss issues related to antibiotic resistance and to work toward increased antibiotic stewardship in human medicine and animal health. Throughout the dialogue, attention focused on specific areas that can be measured to verify progress made in reducing antimicrobial resistance.


Don’t let nitrates cost cattle lives

Will you feed cane, millet, or oat hay, or maybe corn stalk bales, to your cows this winter? If so, don’t let high nitrate levels kill your cows or cause abortions.

Nitrates occur naturally in all forages. At low levels, nitrates either are converted into microbial protein by bacteria in the rumen or they are excreted. But when nitrate concentrations get too high, they can kill cows and maybe abort calves.


Silage pile management and safety

It is easy to see the importance silage plays in ruminant livestock rations by observing the number of bunker silos and silage piles that are on area farms. Feeding out that stored silage requires management. Silage management can be discussed from two perspectives, one being how to manage the removal of silage from the silo to maintain silage quality and promote animal intake and the other on how to keep farm workers, family, and visitors safe around the bunker.


Cattle carcass weights increase, packer margins under pressure

Cattle carcass weights are at record levels and continue to increase counterseasonally. As of the week ending October 24th, average steer weights were reported at 927 pounds (+3 percent year over year) and average heifer weights at 841 pounds (+2 percent year over year). Several factors have contributed to the rapid increases in cattle weight gain. First, the costs of feeding cattle have become considerably lower and there is excess capacity in the feeding sector.
