‘As fed’ or ‘dry matter’ — does it matter?

Nutrition with John McKinnon

By
When I visit with beef producers about their feeding program, I often sense confusion when I talk feed dry matter (DM) values or express intakes on a DM basis. Most producers, when they think of their feeding program, think “as fed” and have difficulty converting to DM. Getting this conversion correct, however, is critical to […] Read more

In my August column, I wrote on the topic of creep feeding, a practice that many producers utilize to improve body condition and weaning weights, particularly during drought situations. Unfortunately, as summer has unfolded, significant areas of the country have experienced abnormally dry conditions, and as a result, many producers are scrambling for winter feed […] Read more

Cattle deaths from larkspur poisoning have plagued the industry for well over a century. This year appears to be no different, particularly in British Columbia where there has been a marked increase in larkspur-related death losses. Recently, I was asked by a colleague if a strategic mineral supplementation program would provide any relief from larkspur […] Read more

By
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
