New diagnostics to inform antimicrobial treatment decisions
Bovine respiratory disease (BRD) remains the most common and economically important disease affecting feedlot cattle. About 15% of cattle in North America are treated for BRD, and it accounts for about 70% of the illnesses and 40% of deaths. Economic losses to the North American beef industry exceed $1 billion dollars annually.

Improving grazing capacity with bloat-free legumes
Including legumes in a pasture improves biodiversity, forage quality, forage yield, and soil nutrient status without having to apply extra nitrogen fertilizer. While alfalfa has long been the legume species of choice, concerns about bloat have often limited its inclusion into forage stands.

Best methods for pasture rejuvenation
There are several pasture rejuvenation options available to producers that are superior to break and reseed. Which method is right for you will depend on how depleted the pastures are in terms of soil nutrients, the ability to take on up-front capital costs, whether or not legumes are present in the stand, and whether the weather cooperates.

Winter hardy alfalfa
Current varieties of winter hardy alfalfa enter into dormancy in late summer and early fall, meaning that growth ceases during that time. While they are grazing tolerant and winter hardy, after the first graze or cut, regrowth does not occur to an extent that permits a second cut or more flexible grazing systems.

Rejuvenating sainfoin in existing alfalfa and grass pastures
Despite the high nutritive value and yield of alfalfa, it cannot generally be used in pure stands due to risk of bloating. Legumes that contain tannins, like sainfoin and birdsfoot trefoil protect against bloating, but use of sainfoin has traditionally been limited due to the lower forage yields and slow establishment of older varieties.

Quantifying yield and quality of perennial varieties and mixtures
Producers are increasingly interested about perennial forage varieties and mixtures. While some yield and agronomic data may be available on these varieties from seed companies, regional data specific to soil type and growing conditions has been limited due to very little participation in the Western Forage Variety Testing System in recent years.
