Vitamins to consider when cattle feeding

Nutrition with John McKinnon

By
Over the years, I have had the opportunity to discuss winter feeding programs with numerous cow-calf producers across the country.

The winter of 2016-17 is shaping up to be a challenge for cow-calf operators across Canada.

Barley variety and silage quality

Research on the Record with Reynold Bergen
