National Beef and JBS have announced they won’t change their cattle buying practices in regards to Zilmax, but will monitor the situation closely. Tyson banned product produced with the feed additive starting Sept. 6 and Greater Omaha followed suit. Iowa Cattlemen’s President Elect and Vet Dr. Phil Reemtsma says Tyson claimed the product was impacting the animals ability to walk.
He says it’s unclear if other packers will eventually follow, whether or not producers will switch to another beta agonist like Optaflexx and what this will mean for exports.
He says Zilmax is an effective tool for cattlemen with gains of 24 to 33 pounds and a return of $15 to $22 per head verses only 10-12 pounds for Optaflexx.
