bambermycins needed for your complete feeding program.
CATTLE FED IN CONFINEMENT FOR SLAUGHTER:
**THE APPROVED DOSAGE IN CATTLE FED IN CONFINEMENT FOR SLAUGHTER IS 10
TO 20 MG OF BAMBERMYCINS/HD/DAY. The amount of bambermycins will range between
1 and 4 grams per ton of feed depending upon the daily feed consumption of the cattle fed in
confinement for slaughter. The amount of Type A Medicated Article added to the complete
ration (Type C Medicated Feed) must be based on daily feed consumption, the number of
animals in the pen and the level (10-20 mg/hd/day) of bambermycins being fed. From this
information the grams of bambermycins per ton of feed can be calculated in order to fulfill
feed assay requirements. No Type C Medicated Feed should be manufactured with less than
1 g bambermycins/ton. Feed assays for bambermycins with expected levels below 1 g/t may
not be accurate. See the following table for conversions from mg/hd/day to g/t.

Example Calculation —Amount of GAINPRO®-10 premix added to feed for a pen of cattle.
Given: Average Weight—800 lbs.; Number in pen—100 hd.; Dosage—20 mg/hd/day; Daily
Feed Consumption—22 lbs./day.
• 100 hd x 20 mg = 2,000 mg or 2 grams bambermycins.
• GAINPRO®-10 contains 10 grams bambermycins/lb., therefore add 0.2 pound of
GAINPRO®-10 premix to the daily feed for this pen of 100 animals.
• 22 lbs./day x 100 hd = 2,200 lbs. total feed consumption.
• 2 grams bambermycins ÷ 2,200 lbs. = .000909 g/lb.
• .000909 x 2,000 lbs. = 1.82 g bambermycins/ton of feed.
It is recommended that GAINPRO®-10 be diluted with a suitable grain carrier before addition
to the final feed. A dilution of 1 part of GAINPRO®-10 and 9 parts grain carrier is the
suggested working premix. The table below shows premix and working premix addition levels
for various commonly used feeds.
Pounds Premix To Be Added Per Ton
Feed Bambermycins Level GAINPRO®-1 1-9 Working Premix
Cattle Fed in 1 gram/ton 0.1 1
Confinement 2 grams/ton 0.2 2
for Slaughter 3 grams/ton 0.3 3
4 grams/ton 0.4 4
Thoroughly mix both working premix and finished feed to ensure complete and uniform
distribution of the GAINPRO®-10.
Feeds containing GAINPRO®-10 should be fed continuously in a complete feed. Complete
feed for cattle fed in confinement for slaughter must be fed continuously at a rate of 10-20 mg
bambermycins/hd/day from Type C Medicated Feed containing 1-4 g bambermycins/ton.
TYPE B LIQUID FEEDS INTENDED FOR ADDITION TO DRY FEEDS FOR
•Type B Liquid Feeds should be in a pH range of 3.8 to 7.5 and should have a moisture
content between 30 and 45%.
•Type B Liquid Feeds must be mixed into the dry feed within 8 weeks of manufacture.
•Type B Liquid Feeds can be manufactured containing 40.0 to 800.0 g of bambermycins/ton.
Mixing directions into dry feed are as follows:
Before feeding, the Type B Medicated Liquid feed must be thoroughly mixed with other feed
materials to make a complete feed (Type C Medicated Feed). Examples of addition rates to
complete feeds are shown in the following table.
Addition Rate of Type B Bambermycins (g/ton) in

The complete dry feed (Type C Medicated Feed) may only be fed to cattle in confinement for
slaughter and must be fed within one week after mixing.
***THE APPROVED DOSAGE IN PASTURE CATTLE IS 10 TO 40 MG OF BAMBERMYCINS/
HD/DAY. Daily intakes of bambermycins in excess of 20 mg/head/day have not
been shown to be more effective than 20mg/head/day. Blend 0.8 pound of GAINPRO®-10
with 1999.2 pounds of suitable grain carrier. This supplemental feed will contain 4 mg bambermycins
per pound (8 g/ton). This supplemental feed can be fed at a rate of 2.5 to 10
pounds per head per day to achieve a daily intake of 10 to 40 mg bambermycins/head/day.
See the following table for additional examples of conversion from mg/hd/day to g/t.
It is recommended that GAINPRO®-10 be diluted with a suitable grain carrier to provide a
supplemental feed. The table below shows examples of premix addition levels.
Feed Bambermycins Level To Be Added Per T on Feeding Rate
Pasture 2 grams/ton 0.2 10.0 lb./hd/day
Cattle 4 grams/ton 0.4 5.0-10.0 lb./hd/day
8 grams/ton 0.8 2.5-10.0 lb./hd/day
20 grams/ton 2.0 1.0-4.0 lb./hd/day
40 grams/ton 4.0 1.0-2.0 lb./hd/day
80 grams/ton 8.0 1.0 lb./hd/day
Thoroughly mix both working premix and supplemental feed to ensure complete and uniform
distribution of the GAINPRO®-10.
Feed for Pasture Cattle must be fed continuously at a rate of 10-40 mg bambermycins/hd/day
in at least one pound and not more than 10 pounds of Type C Medicated Feed containing 2-
40 g bambermycins/ton. Daily intakes of bambermycins in excess of 20 mg/head/day have
not been shown to be more effective than 20 mg/head/day.
FREE-CHOICE (SELF-FED) SUPPLEMENT:
Free-choice supplements must be formulated to provide not less than 10 mg nor more than
40 mg bambermycins per head per day. An FDA approved formula must be used to manufacture
free-choice medicated feeds containing bambermycins. Feed mills that use a proprietary formula
are required to be licensed.
