Improve pasture health and help protect your livestock from poisonous weeds

Grass production isn’t the only thing that could suffer when invasive weeds, brush and trees invade your permanent grass pasture and rangeland.

Many common invasive weeds in Western Canada, such as tansy ragwort, tall buttercup and hoary alyssum, are poisonous to livestock. While cattle will generally avoid toxic plants because of their bitter taste, poisonings can often occur early or late in the season when desirable forage plants are in shorter supply1.

The impact of invasive weeds

Invasive weeds spread aggressively, reducing the quality and quantity of forage available by making them less accessible or attractive to grazing animals and by competing with desirable plants. In fact, weeds can rob a pasture of up to 63 per cent of forage yield, if left untreated.

Additionally, livestock can be poisoned or injured while grazing certain plants2. These plants contain toxic compounds that can result in weight loss, weakness, rapid pulse and un-thriftiness3

However, with good pasture management, you can keep desirable forage species throughout the grazing season and reduce the possibility of your animals grazing poisonous weeds.

Growing more grass and managing it well will also help maximize your operation’s profitability. See our article on how growing better grass can help you boost your bottom line.

Effective and sustainable pasture management
