They know when it's not Bovatec®

When it comes to feed supplements cattle have a discerning palate.  Bovatec® has been shown to be more palatable then monensin1. This means better consumption of your feed or supplement when you choose Bovatec®.  It improves liveweight gains and feed conversion efficiency on pasture while controlling clinical signs of coccidiosis in animals exposed to infection around feeding and watering points.  Bovatec® has also been shown to improve the absorption and retention of Phosphous5,6 which is critically deficient in many Australian forage systems.

The cost of coccidiosis

Calves are particularly vulnerable to the disease coccidiosis.  Caused by the protozoans Eimeria zuernii or Eimeria bovis, coccidiosis can impair performance and prevent calves from weaning at their optimum age and weight.  If left untreated it can escalate from watery faeces and reduced growth to bloody scours and even death.

Cattle prefer Bovatec®

The application of lasalocid (Bovatec®) to grazing cattle that are hand fed or have access to free-choice supplements have been intensively investigated and summarised (FDA 2001).

In 15 field studies when Bovatec® is incorporated in the grain supplement to slaughter, stocker (backgrounded), or feeder cattle between 60 and 200 mg/hd/day, the cattle had significant (P<0.05) improvement in gain over the cattle fed the grain supplement without Bovatec®.

Bovatec® does not impact feed intake as much as monensin1.  Brazle and Kuhl (1986)confirmed Bovatec® is more palatable than Rumensin®. This makes Bovatec® the preferred ionophore for free-choice, mineral-based supplement systems2.
