Stepping up to wheat-based finishing diets in cattle

Research on the Record with Reynold Bergen

By
Grain-based diets improve feed efficiency, but increase the risk of rumen acidosis. Rumen acidosis occurs when rumen pH drops below 5.6 for more than three consecutive hours. Severe or chronic acidosis is an animal welfare concern due to rumen damage, liver abscesses, lameness, and an economic cost due to compromised feed conversion and growth performance. […] Read more

Understanding your protein supplement

Nutrition with John McKinnon, beef cattle nutritionist

By
In my last column, I wrote about what a crazy year it has been for growing and harvesting hay. The variability in this year’s hay crop will force many producers to purchase supplemental feed in order to meet the nutrient requirements of their cattle this winter. Last month we looked at alternate feed sources that […] Read more

Rumen microbes and bloat in cattle

Key to the prevention of bloat is understanding the role the bacteria community plays

By
Bloat is marked by impairment in the ability of cattle to expel gas from the rumen, a process known as eructation. Gases including carbon dioxide and methane are produced during normal fermentation and their accumulation in the rumen causes severe distention of the first two compartments of a cow’s stomach, compressing the lungs and heart […] Read more

The trials and troubles of feeding monensin to cattle

It works just as well at the new higher rate, just be sure you are feeding the correct rate

By
Now that the Canadian Food Inspection Agency (CFIA) has raised the safe rate for monensin to 48 parts per million per kilogram of dry matter from 33 ppm, Dr. Katie Wood wanted to know if the proven benefits to feeding monensin still held true at this higher rate. Monensin is an ionophore that increases overall […] Read more

In search of healthy beef cattle livers

By
Liver abscesses continue to be an economic concern for the beef industry, even with modern feeding practices. They are worth around 60 cents a pound if suitable for human consumption, but more important than the direct loss when abscessed livers have to be condemned is the effect on performance and carcass characteristics. Brittany Wiese, a […] Read more

Cocktails for cattle under stress

News Roundup from the September 2015 issue of Canadian Cattlemen

By
Cells lining the inside of your digestive tract are on guard 24-7 letting nutrients into the bloodstream and blocking harmful substances from entering the bloodstream. It’s no different in cattle. Barrier function of the bovine intestinal tract is the subject of new research in progress at the University of Saskatchewan where master’s candidate Rae-Leigh Pederzolli […] Read more

Can twine kill a cow?

Unless the animal is cut open to determine the cause of death, many producers never know what happened

By
Cattle can die from eating twine or net wrap left on big bales or put through the bale processor. And Dr. John Campbell, head at the Western College of Veterinary Medicine, in Saskatoon thinks it happens more often than we think. “I don’t have a lot of data, unfortunately, but I’m starting to believe this […] Read more

Strategic protein supplementation in beef cattle

Mismatches in dietary energy and protein availability in the rumen negatively affect performance

By
In the May and June issues of this column, we examined how stage of maturity influences the nutritive value of forages for grazing cattle. The focus was on factors influencing the availability of energy and crude protein (CP) in forages and on the ability of rumen bacteria to utilize these nutrients to support their own […] Read more

Feed the rumen first: Part 2

By
Last month we discussed the dynamics of rumen fermentation and the contribution that rumen microbes, particularly bacteria make to the nutrition of cattle. For those of you who missed that column, I will summarize by stating that achieving a desired level of performance whether we are dealing with a bred cow or a finishing steer depends to a large extent on how […] Read more

Feed the rumen first!

By
Beef producers often have questions on the relative feed value of the different forages, grains and byproduct feeds they have access to. Many of these questions centre on energy and protein content, how much to feed and what type of supplement, if any is required. Understanding relative feed value and the need for specific supplements […] Read more
