A new webpage on BeefResearch.ca provides an overview of what mycotoxins are, the threat they represent for Canadian beef production and how to implement best practices to protect beef cattle.
Mycotoxins are often hidden hazards – a group of harmful toxins produced by certain types of fungi including mould that are only detectable with lab testing. They can create a variety of problems for beef cattle including reduced health and productivity.
The source of mycotoxins are fungi, including mould, that can be present in green pastures, cereal swaths, standing corn for winter grazing, cured and ensiled grass, cereal forages, crop co-products (straw, distillers grains, grain screenings, oilseed meals) and commercial feeds. Continue reading →
Before things get too busy with the fall run, take some time to learn more about (or refresh your memory on) some of the ways to promote calf health, feed efficiency and carcass quality in the animals that will be on feed in your lot this year. Continue reading →

Ergot develops when a fungus called Claviceps purpurea infects susceptible grass and grain plants during flowering. Rye is most susceptible annual crop, followed by triticale, then wheat. Barley and oats are less susceptible but not completely resistant. Ergot is not a concern in corn. Ergot can also infect a number of perennial grasses. Cool, damp weather conditions during the flowering period (like those in Western Canada over the last few years, and that appear to be shaping up again this summer) cause the flowers stay open longer. This allows more opportunities for ergot spores to spread and infect the seed head. Ergot spores can survive for a year on the soil surface. Less summer fallow, continuous grain-on-grain rotations and un-mowed grass in road allowances allow ergot spores to build up in the soil and help the disease cycle to continue and build.
