Development of a biological control program for common tansy
Previous research showed that there are potential biological control agents for common tansy. Several European insects were collected, identified and subjected to studies to test how well they controlled common tansy. These tests also examined how likely the insects were to consume only common tansy as compared to other related plants.

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.

Factors affecting the fed cattle basis
Basis influences feedlot profitability. The “fed cattle basis” is the difference between the prices that U.S. and Canadian packing plants pay for fat cattle, adjusted for exchange rate. In a normal market, basis reflects transportation costs and differences in supply and demand between Canadian and U.S. markets.

Identifying efficient cattle using infrared technology
This project examined the relationship between infrared thermographic images (IRT) and residual feed intake (RFI) in cows and feedlot cattle to determine whether IRT could be used as a lower cost method to identify and rank animals with improved feed efficiency.

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.
