Claim 1 |

Lasalocid Sodium at 200 g/kg |
Approved for use in meal or pellet feed
Claim 1
For increased rate of weight gain in pasture cattle (stocker cattle, feeder cattle, and beef and dairy replacement heifers).
Level of medicating ingredient in a complete feed
200 mg of lasalocid sodium per head per day.
Directions
Hand-fed supplements
Hand feed continuously a minimum of 0.5 kg of the medicated supplement per animal per day to provide 200 mg of lasalocid sodium/animal/day from the beginning to the end of the pasture season.
Free choice
-
Medicated Mineral Feeds
"Avatec 20" and "Bovatec 20" Premixes may be used in the manufacturing of medicated mineral feeds.
Medicated mineral feeds 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.
-
Medicated Feed Blocks
"Bovatec 20" and "Avatec 20" Premixes may be used in the manufacture of medicated feed blocks.
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 the feed block medicated with lasalocid sodium. Ensure cattle have consumed roughage before introducing the medicated block for the first time.
- If cattle run out of the block medicated with lasalocid sodium, 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 medicated feed block containing lasalocid sodium is 6 months from date of manufacture.
Warning
- No withdrawal period is required when fed according to label.
- Keep out of reach of children (required on premix and supplement labels only)
Caution
- Do not allow horses or other equines access to lasalocid sodium, as ingestion may be fatal.
