What mineral supplementation do I need and when do I need it?
Beef producers might know they should supplement their herds with mineral, but trying to wade through all the choices at the livestock supply store can be overwhelming. Commercial suppliers seem to make claims and offer something different, but with tubs and bags of every colour and price available, how to you know which one is right for your herd? What minerals do your cattle actually need and how is it best delivered?
In general, beef cattle producers should be supplementing mineral to their herds whether they are grazing or being fed a winter ration.
Megan Van Schaik, a Beef Cattle Specialist with the Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) says there are some key things producers want to look at. In general, producers should be supplementing mineral to their herds whether they are grazing or being fed a winter ration.
Van Schaik says there are a host of variables that impact mineral nutrition and deficiencies in beef herds. “They present in many different ways and alarm bells usually go off when we see reproductive issues,” she says, but adds that mineral status can be linked to general health problems and even calf abnormalities. Mineral deficiencies can also cause less obvious production losses that can be easily avoided with proper supplementation. Continue reading →
On July 29, the Beef Cattle Research Council hosted a webinar that allowed beef producers to ask drought-related questions to a panel of nutrition and animal health experts. Producers asked for everything from recommendations for grazing canola, how to manage for antinutritional factors, tips on ammoniation and to how to manage grass into the fall. While questions were varied and diverse, a few main themes emerged.
In a drought year, testing your feed sources is more important than ever. Especially when using alternative feed sources, a feed test allows you to understand what you have in terms of energy and protein and therefore what you will need to supplement to maintain the health and body condition of cows and other classes of cattle. A feed test will also identify some of the antinutritional factors and potential toxic levels of substances such as nitrates or sulfates that are more prevalent in drought years or unconventional feeds. Feed tests can be performed on standing or swathed crops, bales or silage. A feed test can be instrumental in determining how a particular feed will fit into your overall feeding strategy.

When stock water appears abundant and water quality has been consistent in previous years, it’s easy to focus on other things but don’t overlook water testing. Poor quality stock water can lead to reproductive inefficiency, poor gains, disease and in extreme circumstances, death. Even when water supplies appear abundant, stock water may contain high levels of sodium, sulphates or other compounds that lead to toxicity.

Water quality can be especially variable in surface water sources, such as dugouts, ponds or dams, and weather doesn’t necessarily need to be hot and dry to warrant regular testing. Precipitation levels in the previous years, groundwater recharge, runoff conditions, evaporation levels and adjacent land use can all impact water quality in both the short- and long-term.
It’s also important to monitor well water conditions. Quality in well water can change quickly, even if wells have had suitable water in the past.
Beef producers often worry about having too much water or not enough on their farms. However water quality, particularly in fluctuating stock water sources, may go unnoticed. As the summer wears on, evaporation, low rainfall, and consumption can cause the quantity and quality of surface water to dwindle. Meanwhile, hot and dry conditions cause cattle to be at their peak water demand.
“Poor quality drinking water is often a factor that limits intake,” said Leah Clark, livestock specialist with the Saskatchewan Ministry of Agriculture. “When we limit intake we limit production,” she explained in a recent webinar, adding that poor stock water quality can impact animal performance through reduced gains and decreased reproductive success. In severe cases, water quality issues can lead to disease and death. Testing stock water may be particularly important during a drought, when minerals and nutrients can become concentrated as water tables drop in surface or ground water.
Recent producer surveys indicate most Canadian farmers need to test water more often. In western Canada, 59% of producers reported they don’t test their water, and only 17-41% of Quebec and Ontario producers reported testing water once every five years.
