Active drug ingredient
Each pound contains 150 grams (33.1%) of lasalocid (as lasalocid sodium activity) in a carrier suitable for incorporation in feed.
Important
Handling Information - Must be thoroughly mixed in feeds before use. When mixing and handling lasalocid Type A medicated articles, use protective clothing, impervious gloves and a dust mask. Avoid contact with eyes. Operators should wash hands thoroughly with soap and water after handling.
Mixing directions
This product should be further diluted in an intermediate blending step prior to mixing in the final feed. Do not feed undiluted.
1. Complete Feed
a. Intermediate blending: Mix 1 part of Bovatec 150 FP (Type A Medicated Article) with 29 parts of finely ground nonmedicated feedstuffs to provide an intermediate preblend containing 5 grams of lasalocid per pound.
b. Using the 5 g/lb intermediate preblend, the following table would apply to the manufacture of complete feeds:
| Intended lasalocid concentration in the complete feed | Add the following amounts of 5 grams per pound intermediate preblend per ton of complete feed mixed: | |
|---|---|---|
| grams/ton | mg/lb | lbs/ton |
| 10 | 5 | 2 |
| 15 | 7.5 | 3 |
| 30* | 15 | 6 |
* Maximum approved concentration for complete feeds for cattle fed in confinement for slaughter and sheep in confinement
c. Using the 5 g/lb intermediate preblend, the following table would apply to the manufacture of other complete feeds and supplements that do not require further mixing:
| Daily feeding rate | Desired daily lasalocid intake | Add the following amounts of 5 grams per pound intermediate preblend per ton of feed or supplement mixed: | Lasalocid will be present in the feed or supplement at the following concentration: |
|---|---|---|---|
| lbs/head/day | mg/head/day | lbs/ton | grams/ton |
| 1 | 60 | 24 | 120 |
| 200 | 80 | 400 | |
| 300 | 120 | 600 | |
| 2 | 60 | 12 | 60 |
| 200 | 40 | 200 | |
| 300 | 60 | 300 | |
| 3 | 60 | 8 | 40 |
| 200 | 26.7 | 133.5 | |
| 300 | 40 | 200 |
2. Dry Supplement
a. Intermediate blending: Mix 1 part Bovatec 150 FP Type A Medicated Article with 6.5 parts of finely ground nonmedicated feedstuffs to provide an intermediate preblend containing 20 grams of lasalocid per pound. For example, mix one 50 lb bag of Bovatec 150 FP Type A Medicated Article with 325 lbs of non-medicated feedstuffs.
b. Using the 20 g/lb intermediate preblend, the following table would apply to the manufacture of dry supplements:
| Intended lasalocid concentration in the supplement | Add the following amounts of 20 grams per pound intermediate preblend per ton of supplement mixed: | |
|---|---|---|
| grams/ton | mg/lb | lbs/ton |
| 400 | 200 | 20 |
| 600 | 300 | 30 |
| 1000 | 500 | 50 |
| 1440 | 720 | 72 |
| 1600 | 800 | 80 |
c. Thoroughly mix supplement with sufficient non-medicated feedstuffs in accordance with the feeding rates listed in the use directions below.
3. Liquid Supplement Intended for Addition to Dry Feeds
a. Supplements with suspending agent(s) should be in a pH range of 4-8 and maintain physical stability for up to three months with a viscosity not less than 300 cps.
b. Conventional liquid supplements should be in a pH range of 4-8.
For liquid feeds stored in recirculating tank systems: Recirculate immediately prior to use for no less than 10 minutes, moving not less than 1 percent of the tank contents per minute from the bottom of the tank to the top. Recirculate daily as described even when not used.
For liquid feeds stored in mechanical, air, or other agitation-type tank systems: Agitate immediately prior to use for not less than 10 minutes, creating a turbulence at the bottom of the tank that is visible at the top. Agitate daily as described even when not used.
Use directions
| Species | Dose | Indications for use |
|---|---|---|
| Cattle Fed in Confinement for Slaughter | 10-30 grams lasalocid per ton of total ration (90% dry matter) | For improved feed efficiency in cattle fed in confinement for slaughter, feed continuously to provide not less than 100 mg nor more than 360 mg per head per day. |
| 25-30 grams lasalocid per ton of total ration (90% dry matter) | For improved feed efficiency and increased rate of weight gain in cattle fed in confinement for slaughter, feed continuously to provide not less than 250 mg nor more than 360 mg per head per day. | |
| Pasture Cattle – slaughter, stocker, feeder cattle, and dairy and beef replacement heifers | 60-300 mg lasalocid per head/day | For increased rate of weight gain. The drug must be contained in at least 1 pound of feed and fed continuously on a daily basis. |
| 60-300 mg lasalocid per head/day |
For increased rate of weight gain, feed continuously on a free-choice basis. Free-choice feed must be manufactured under a medicated feed mill license utilizing an FDA approved formulation. |
|
| Daily lasalocid intakes in excess of 200 mg per head per day have not been shown to be more effective than 200 mg lasalocid per head per day. | ||
| NOTE: Coccidiosis may occur when young pasture cattle are co-mingled with adult cattle passing coccidial oocysts. | ||
| Cattle | 1 mg lasalocid per 2.2 lbs body weight/day | For control of coccidiosis caused by Eimeria bovis and E. zuernii in cattle up to 800 lbs. Hand feed continuously to provide not more than 360 mg per day. |
| Replacement Calves |
1 mg lasalocid per 2.2 lbs |
For control of coccidiosis caused by Eimeria bovis and E. zuernii, hand feed in milk replacer powder. |
