Cows leaving the dairy

Dirty conditions can lead to uterine infections

Barn cleanliness as well as nutrition can be among the contributors

Many dairy cows come down with a uterine infection after calving. Some are slight but some are more serious. While there are host of factors which cause them, some reasons such as a dirty calving area are obvious, other reasons such as persistent metabolic problems are not so clear. Fortunately, a good spring-cleaning and improvements […] Read more


Water and shade reduce impact of heat stress on cattle

Too much heat along with pests can affect breeding success

I am no stranger to the effects of summer heat stress in cattle. Back when I was working on my master’s thesis at the University of Manitoba (the effect of molybdenum on copper status in beef cattle nutrition, 1983), I had 35 Shorthorn/Angus crossbred yearlings on full feed. During that particular summer, after July 1 […] Read more




Nip risk of grass tetany in the bud

Provide a tablespoon or two daily of magnesium mineral supplement before turnout

Every spring, I think about the possibilities of grass tetany in the cow herds going out to graze in on lush prairie grass. While nobody wants to find a fresh cow that died under mysterious circumstances, there is no need to panic. Fortunately, most threats of fatal grass tetany can be reduced by providing beef […] Read more



Dairy Corner: Vitamin A expensive, but necessary

Although the price has shot up, it is important to keep the nutrient in dairy rations

Prices of vitamin A (along with vitamins D and E) have increased to 10 times their former costs from just a few months ago. This skyrocketing price is due to a recent fire at a new manufacturing facility in Germany as well as several vitamin ADE plants that are down for maintenance in China. Together, these events have caused a worldwide shortage […] Read more




Feeding yeast is a good investment

These single-cell organisms can hit on many cylinders to help optimize milk performance

For many years, I have formulated dairy diets with yeast for both dry and lactating dairy cows. It has been my professional intention to promote good dairy nutrition, or solve a particular problem that limits good dairy performance. On occasion, I have seen direct benefits within a couple of days by adding yeast, while other […] Read more


Proper diets take a bite out of wind chill

When temperatures dip, it’s time to torque up the ration

Beef cow diets developed at the beginning of winter when temperatures were mild are not adequate to meet their energy requirements when new year’s winds blow. That’s because pregnant beef cows need extra calories in order to keep warm, rather than burning up fat reserves needed for the upcoming calving season. Therefore, if it is […] Read more




Key tips to reduce milk fever cases

Incidence of the calcium deficiency can be sporadic, but hurt when they hit

Clinical milk fever is a particular insidious metabolic disease in freshened dairy cows. I have witnessed on some dairies, it’s not a significant problem, while next-door neighbours are plagued with downer cows one calving after another. In other dairies, milk fever doesn’t show up for months and then it shows up with a vengeance. From […] Read more
