Bacitracin Methylene Disalicylate
Type A Medicated Article
Antibacterial
For supplementing rations of swine, chickens, turkeys, pheasants, quail and feedlot beef cattle
Active drug ingredient
Each pound contains feed grade bacitracin methylene disalicylate equivalent to 50 grams bacitracin (Master Standard).
Composition
A dried precipitated fermentation product obtained by culturing B. licheniformis Tracy on media adapted for microbiological production of bacitracin; calcium carbonate.
Mixing directions
Prepare an intermediate premix containing 5 grams per pound by mixing 1.0 lb of BMD 50 with 9.0 lbs of a feed ingredient(s) or a portion of the non-medicated feed. Then add 0.8 to 50 lbs of intermediate premix per ton of finished feed.
| Species | Grams bacitracin per ton of feed | Indications for use |
|---|---|---|
| Broiler and replacement chickens | 4 - 50 | For increased rate of weight gain and improved feed efficiency. |
| 50 | As an aid in prevention of necrotic enteritis caused or complicated by Clostridium spp. or other organisms susceptible to bacitracin methylene disalicylate. | |
| 100 - 200 | As an aid in control of necrotic enteritis caused or complicated by Clostridium spp. or other organisms susceptible to bacitracin methylene disalicylate. | |
| CAUTION: To control a necrotic enteritis outbreak, start medication at the first clinical signs of disease. The dosage range permitted provides for different levels based on severity of the infection. Consult a poultry diagnostic laboratory or pathologist to determine the diagnosis and advice regarding the optimal level of drug. Administer continuously for 5 - 7 days or as long as clinical signs persist, and then reduce medication to prevention level (50 g/ton). | ||
| Laying hens | 10 - 25 | For increased egg production and improved feed efficiency during the first seven months of production. |
| Growing turkeys | 4 - 50 | For increased rate of weight gain and improved feed efficiency. |
| 200 | As an aid in control of transmissible enteritis in growing turkeys complicated by organisms susceptible to bacitracin methylene disalicylate. | |
| Pheasants | 4 - 50 | For increased rate of weight gain and improved feed efficiency. |
| Quail | 5 - 20 | For increased rate of weight gain and improved feed efficiency in quail not over 5 weeks of age. |
| 200 | For prevention of ulcerative enteritis in growing quail due to Clostridium colinum susceptible to bacitracin methylene disalicylate. Feed continuously as the sole ration. | |
| Growing/finishing swine | 10 - 30 | For increased rate of weight gain and improved feed efficiency. |
| 250 | For control of swine dysentery (bloody scours) associated with Brachyspira hyodysenteriae in pigs up to 250 lbs body weight. Feed 250 grams per ton of complete feed on premises with a history of swine dysentery, but where signs of the disease have not yet occurred or following an approved treatment of the disease condition. | |
| The 250 g/ton level will provide 5 to 7 mg/lb in swine weighing 40 to 250 lbs. | ||
| CAUTION: Diagnosis should be confirmed by a veterinarian when results are not satisfactory. Feed containing an approved level of bacitracin methylene disalicylate should be the sole ration. | ||
| Pregnant sows | 250 | For control of clostridial enteritis caused by C. perfringens in suckling piglets when fed to sows from 14 days before through 21 days after farrowing on premises with a history of clostridial scours. |
| CAUTION: Diagnosis should be confirmed by a veterinarian when results are not satisfactory. Feed containing an approved level of bacitracin methylene disalicylate should be the sole ration. | ||
| Feedlot beef cattle | mg/head/day | |
| 70 (continuously) | For reduction in the number of liver condemnations due to abscesses in feedlot beef cattle. | |
| 250 (5 days in 30) | For reduction in the number of liver condemnations due to abscesses in feedlot beef cattle. |
Note: Where minimum levels are shown, increase the antibiotic concentration within approved range when necessary to fit the feeding program, and to insure adequate levels of antibiotic in the complete ration.
