Weight Gain



Appetite for success

Bovatec® increases liveweight gains and feed efficiency in beef cattle.

There are times in life when you want your cattle to eat more:

Weaning calves onto pellets
Heifers growing into replacement cows
Growing cattle on high roughage pasture
Feedlot cattle learning to adapt to mixed grain rations

Appetite for success

When nutritional demands increase you need an ionophore which achieves better feed consumption1,2.  Bovatec® has been shown to improve liveweight gains and feed conversion in growing cattle and lot fed cattle.

Data from 18 research papers3 between 1979 and 1996 showed on average Bovatec® increased gains by 6.8% and improved intake/gain ratio by 9.3% across a variety of feedlot, silage and forage rations.

Maximising Weight Gain

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.
