A pest management specialist says horned flies are the top economic threat to cattle in pastures.
Mark Upton with Central Life Sciences tells Brownfield when flies go uncontrolled it makes cattle decreases productivity. “That brute cow is not going to rebreed or raise a calf or produce milk if they have to reduce blood loss. It’s important that we stop that and we’re gaining and seeing the results of our work through the gain of that calf.”
Upton says there are more effective forms of control than fly tags like fly growth regulators that can be added to cattle feed.
