Even moderate cases of this condition can result in decreased milk production, poorer reproductive performance and reduced

The Importance of Vitamin E and Selenium

Source: Government of Manitoba Vitamin E and selenium perform important functions in the cow. Deficiencies of one, or both, of these nutrients have been implicated in white muscle disease, retained placentas, oxidized milk, lower immune function and mastitis. The roles of these two nutrients are closely related. Both selenium and vitamin E protect cells from

The young calf has almost negligible body energy reserves, and is exceedingly vulnerable to infection, especially those predominant in the gastro intestinal tract. Scouring results in dehydration and may cause fever. These physiological states are stressful

Preventing Milk Fevers

Costs can easily exceed $400/cow in terms of vet and drugs, discarded milk and lost milk production. Cows with milk fever are also more likely to develop other metabolic diseases including retained placentas and ketosis. As with

Prevention and Control of Foot Problems in Dairy Cows

Source: Extension Introduction Foot health and lameness are major issues facing dairy producers because of their common occurrence and the tremendous economic losses incurred. Early detection and prompt treatment can minimize the loss, improve recovery, and reduce animal suffering. Economic loss is mostly due to the foot problems per se, not the treatment costs. Losses

Making better milk through cow behaviour

Source: University of Guelph What if dairy farmers could improve their cows’ health and enhance milk’s nutritional quality through understanding their animals’ feeding behaviour? That’s what University of Guelph researcher Trevor DeVries is helping them do. He’s the Canada Research Chair in Dairy Cattle Behavior and Welfare and associate professor in the university’s animal biosciences

Focus on Feet: Wet feet may be okay for ducks but moisture can lead to cows on the limp

Source: Ontario Ministry of Agriculture, Food and Rural Affairs Providing dry footing for your herd may be one of the keys to promoting healthy hooves. One group of researchers has been looking into the notion that environmental conditions on some farms may be causing changes to feet that make cows more prone to foot ailments.

A reminder of calf needs should be outlined, especially with the primary calf worker(s). Topics of focus should involve: Optimal nutrition, the
