Whether in the form of pasture, stored forage, or supplements, feed is the largest variable input cost in cow-calf operations. A big challenge is to feed the cow in a way that meets her current and future nutritional requirements for maintenance, lactation, maintaining a successful pregnancy, giving birth and getting rebred within 80-85 days of calving as cost effectively as possible. This challenge is obviously much greater during drought, when feed is scarce and expensive.
With many parts of the country experiencing extreme heat, it is important to remember that cattle aren’t able to dissipate heat well and are more susceptible to heat stress.
Environment Canada has issued a heat warning for mostly rural areas of east central and southeast Alberta. Temperatures are expected to top 29C to 32C for daytime highs for longer than a week, an unusually long duration for such a heat wave.
Now that Canada is in the midst of the shortest and coldest days of the year, light and heat management are top of mind for many producers who operate greenhouses.
