Cautionary post on the dangers of bale net wrap and preventive measures that can be taken.
Bale net wrap does a great job of preserving feed quality, but if your horse happens to eat remnants of the plastic wrap, it can cause some serious health issues.
Dr. Alannah Friedlund, a veterinarian and large animal surgical resident at the Western College of Veterinary Medicine (WCVM), is seeing a growing number of horses that have ingested net wrap, and as a result, have developed colic.
“This net wrap makes it all the way to the small colon, which is the very last stop before the rectum,” says Friedlund. “This is where it seems to get caught in every single case.”
In the small colon, Friedlund says the net wrap gets twisted around f***l balls, forming a “rosary-style chain” that the horse can’t excrete. These horses present with typical colic symptoms but treating with fluids and pain medication rarely work.
Instead, these cases require costly colic surgery with a 50-50 recovery rate.
Friedlund says awareness is critical for avoiding this serious issue, and she recommends following five safe feeding practices.
1. Remove all net wrap from hay bales before feeding
2. Consider alternative feeding methods to make it easier to identify and remove potential hazards
3. Always remove net wrap before processing bales into chopped hay
4. Regularly check fields and paddocks for net wrap debris
5. Call your veterinarian if your horse shows any signs of colic
