Halt in Zilmax sales fuels demand for rival cattle feed Product

CHICAGO, Aug 24: Merck & Co’s decision to suspend sales of its Zilmax cattle feed additive has caused such a surge in demand for rival Eli Lilly & Co’s Optaflexx that Lilly is telling some new customers it cannot immediately supply them, customers told Reuters. Zilmax became the focus of attention in the livestock industry after Tyson Foods Inc said on August 7 that it will stop buying Zilmax-fed cattle for slaughter beginning next month. Tyson, the biggest US meat processor, said it was concerned about Zilmax potentially causing health problems for some cattle. (agencies)
