When people think about tetany, they think of something that happens only during the spring. It’s something that usually occurs when cattle are eating lush spring grass or annual cereal forages. However, it can also happen when cattle are fed harvested forages like silage or hay.
Grass tetany is most often paired with cattle grazing immature cool-season grasses or lush annual forages. The thing about it is that tetany can also happen during the winter when cattle are being fed hay. Tetany can happen with regular hay, alfalfa hay, or annual forages that have been harvested for hay. It is especially true if the hay is being fed in a dry lot and is the only feed source.
For those of you not in the know, you may be asking, “What is grass tetany?“, “What kinds of problems can it cause my operation?” and “How do I treat or even prevent it from happening?“. In regard to those questions, here are some things you should consider.
