    Medicated minerals should be fed free choice continuously from the beginning to the end of the pasture season. Aim for a consumption rate of 125 g medicated mineral per head per day, which will provide the recommended dose of 200 mg lasalocid sodium/animal/day. Increase the distance of the medicated mineral from the water source to decrease consumption of the mineral and visa-versa.

  2. Medicated Feed Blocks

    "Bovatec 20" and "Avatec 20" Premixes may be used in the manufacture of the following medicated blocks only:

    1. Sup-R-Growth Block with Bovatec/Sup-R-Bloc Génitaure avec Bovatec, Agribrands Purina Canada Inc.

    Medicated Blocks should be fed free choice continuously from the beginning to the end of the pasture season. Aim for a consumption of 1.0 kg of the medicated feed block per head per day, which will provide the recommended dosage of 200 mg of lasalocid sodium per animal per day.

    • Introduce a 1:1 or 2:1 (Ca: P) free-choice mineral with salt two weeks before introducing Sup-R-Growth Block with Bovatec. Ensure cattle have consumed roughage before introducing Sup-R-Growth block for the first time.
    • If cattle run out of Sup-R-Growth Block with Bovatec, observe intake closely for three days after replacing the block, to prevent over consumption.
    • If consumption is too low, bring blocks closer to the watering and resting areas. In large pastures, blocks should be available in more than one location.
    • If consumption is higher than desired, move blocks further away from the watering and resting areas, and/or reduce the number of blocks available to cattle.
Additional information to be added as notes to feed labels
  • Expiration of the Sup-R-Growth Block with Bovatec is 6 months from date of manufacture

Warning
