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.
