Optimise return on every pen with Optaflexx®.

Optaflexx® is a feed ingredient indicated for increased rate of weight gain, improved feed efficiency, and increased carcass leanness in confined cattle greater than 400 kg (882 lb), when fed during the last 28 to 42 days prior to slaughter.

Research has demonstrated that Optaflexx increases live weight1,2 average daily gain1,2,3,4 feed efficiency1,2,3,4 and carcass weight1,2,3,4.

Optaflexx feeding directions give producers the flexibility they need to respond quickly to market signals, and capitalize on the benefits, whether selling cattle live or on a carcass weight basis.
