Improved understanding of Johne’s Disease
Blood samples and fecal shedding status were obtained from 25 MAP infected cows (as identified by the current ELISA test). Cows were split into four groups: ELISA and fecal high, ELISA high and fecal low, ELISA low and fecal high, and ELISA low and fecal low.

Effect of feeding distillers grains on health in the feedlot
Increased usage of DDGS in beef cattle diets has arisen from the rising costs of traditional feedstuffs. When wheat or corn are fermented and distilled, the starch is converted to alcohol. The fat, protein, and fiber from the grain are concentrated in the DDGS by-product, resulting in higher levels of those nutrients than the parent grains.

Novel vaccination strategies for bovine viral diarrhea virus
Current BVD vaccines exist in either a modified live or killed form. While modified live vaccines are generally effective, they are not safe for use in and around pregnant cows. Killed vaccines are safe for all classes of animals, but have lower effectiveness in terms of inducing cell-mediated and long-term immunity.

Trying to prevent Mycoplasma
Mycoplasma bovis has become a significant bacterial pathogen in commercial feedlots over the past decade or so. Since Mycoplasma bacteria lack a cell wall, antibiotics (which disturb bacterial cell walls) are not very effective for treating cattle infected with these bacteria.

Mycoplasma bovis strains derived from calves in commercial feedlots in western Canada
The objectives of this study are to: determine the prevalence of Mycoplasma bovis in fall-placed feedlot calves; describe the ecology of M. bovis within pens of feedlot calves; and determine if specific strains of M. bovis are related to disease in the feedlot.

Evaluating industry cattle transport practices
This study should help to inform discussions about how Canada’s beef industry raises, manages, handles and transports cattle. It will also help to identify real problems so that industry can develop cost-effective ways to correct any issues that are identified.
