Is it safe for cattle?

Yes. The FDA, Canadian Food Inspection Authority (CFIA) and other international scientific authorities have approved Zilmax as a safe and effective feed supplement for cattle.1

In 2006, after reviewing years of research, the FDA concluded that Zilmax was safe for use in cattle.1 Similarly, in 2009 the CFIA approved Zilmax for use in Canada. Many other major beef producing countries worldwide approved the product prior to that. In fact, some countries have been using Zilmax for two decades. During that time, there have been no negative effects on the well-being of cattle, when the product is used according to label directions along with good animal care practices.1,10-20 In 2014 and 2015, FDA and CFIA, respectively, reconfirmed the safety of the product when they approved a new label that allows cattle farmers a more convenient and efficient method of feeding this supplement.
