Creep feeding is a management practice where nursing calves are fed supplemental feed while on pasture. Its economic benefits have been hotly debated by those in industry and academia alike. Those in favour point to the increased value of heavier calves at weaning, the potential sparing of summer forage supplies, and the health benefits associated […] Read more

In my April column I focused on the principles of protein nutrition in beef cattle with an emphasis on rumen degradable and undegradable protein and on meeting the metabolizable protein needs of the animal. The reason that I focused on this topic was my experiences this past winter with producers who were having difficulty meeting […] Read more

This year is one of reflection and celebration for the staff and readers of Canadian Cattlemen as it celebrates 80 years of publishing. In the spirit of this celebration, I would like to reflect on and celebrate the life of a man whose passion for Canada, Canadian agriculture and in particular the Canadian beef industry […] Read more

With respect to cattle nutrition, there are some topics that never seem to go away. They might drop out of the spotlight for a period of time, but they always seem to re-emerge, typically at a critical time in the production cycle. I could give numerous examples, but for the purposes of this and next […] Read more
When I visit with producers about their feeding program, I often get questions on “nutrition lingo.” Examples include questions on the meaning of a mineral or protein supplement tag or how much supplement do you need to feed to achieve an ionophore concentration of 22 or 33 ppm? Such confusion is understandable, particularly when you […] Read more

Many of you are likely aware that the feed industry is facing a critical shortage of vitamins A and E. This shortage is the result of a fire in October at a processing plant in Germany owned by BASF, one of the global leaders in the provision of vitamins for humans and livestock. The damaged […] Read more

The winter of 2017-18 is shaping up to be full of unexpected challenges, particularly for those wintering cows in Western Canada. Drought, as well as recent wildfires, have caused many producers to scramble for a forage supply. As well, “old man winter” in all his wisdom has arrived early, with November temperatures in the minus […] Read more

It is a time of year when feedlot operators and cow-calf producers are implementing their winter feeding programs. Forage, whether it is fed as hay, stockpiled forage (i.e. barley swaths or standing corn) or silage will play a big role in the vast majority of these operations. For feedlot operations, good-quality hay is often used […] Read more
Research on the Record with Reynold Bergen
Getting weaned calves on feed can be a challenge. This is often attributed to the change from a forage-based diet to unfamiliar feedlot rations and feed bunks, distress from recent weaning, illness, etc. To compensate for this, some feeders use a relatively high-energy receiving diet, the rationale being that if they’re not going to eat […] Read more

Averages are useful statistics, but sometimes averages can be misleading. As the University of Saskatchewan’s late Iain Christison said, “the average human has one breast and one testicle.” Canada’s rainfall may be close to average this year — but much of the country is experiencing severe drought, and most of the rest is soaked. Either […] Read more
