Directions for Use: Thoroughly mix Bovaer 10 into a total mixed ration at 540‐720 g/ton of complete feed (100% dry matter basis) to provide 27.2‐36.3 mg 3‐nitrooxypropanol per pound (60‐80 mg per kilogram) of dry matter intake.  Feed continuously to lactating dairy cows. 


PRADALEX

INDICATIONS
Pradalex is indicated for the treatmentof bovine respiratory disease (BRD) associated Mannheimia haemolytica, Pasteurella multocida, Histophilus somni and Mycoplasma bovis in cattle intended for slaughter (beef calves 2 months of age and older, growing beef steers, growing beef heifers, and beef bulls intended for slaughter), and in cattle intended for breeding less than 1 year of age (replacement beef and dairy heifers less than 1 year of age and beef and dairy bulls less than 1 year of age). Not for use in cattle intended for breeding 1 year of age and older (replacement beef and dairy heifers 1 year of age and older, beef and dairy bulls 1 year of age and older, and beef and dairy cows), beef calves less than 2 months of age, dairy calves, and veal calves

CAUTION: Federal law restricts this drug to use by or on the order of a licensed veterinarian and prohibits the extra-label use of this drug in food-producing animals. To ensure responsible antimicrobial drug use, use of pradofloxacin should be limited to treatment of bovine respiratory disease (BRD) in cattle only after consideration of other non-fluoroquinolone therapeutic options.

Not for use in humans. Keep out of reach of children. Avoid contact with eyes and skin. Individuals with a history of hypersensitivity to quinolones should avoid this product. Not for use in animals intended for breeding greater than 1 year of age. Not for use in beef calves less than 2 months of age, dairy calves and veal calves; a withdrawal period has not been established for this product in pre-ruminating calves.

RUMENSIN

The label contains complete use information, including cautions and warnings. Always read, understand and follow the label and use directions.

CAUTION: Consumption by unapproved species or feeding undiluted may be toxic or fatal. Do not feed to veal calves.

Feeding Directions:

Dairy cows: For increased milk production efficiency (production of marketable solids-corrected milk per unit of feed intake):
Total Mixed Rations ("complete feed"):
 Feed continuously to dry and lactating dairy cows a total mixed ration (“complete feed”) containing 11 to 22 g/ton monensin on a 100% DM basis.
Component Feeding Systems (including top dress): Feed continuously to dry and lactating cows a Type C medicated feed containing 11 to 400 g/ton monensin. The Type C medicated feed must be fed in a minimum of 1.0 lb of feed/cow/day to provide 185 to 660 mg/hd/day monensin to lactating cows or 115 to 410 mg/hd/day monensin to dry cows. This provides cows with similar amounts of monensin they would receive by consuming total mixed rations containing 11 to 22 g/ton monensin on a 100% DM basis.

Replacement dairy heifers:
For increased rate of weight gain:
Feed 50 to 200 mg/hd/day in at least 1.0 lb of Type C Medicated Feed. Or, after the 5th day, feed 400 mg/hd/day every other day in 2.0 lbs of Type C Medicated Feed. The Type C Medicated Feed must contain 15 to 400 g/ton of monensin (90% DM basis). Do not self feed.
For the prevention and control of coccidiosis due to Eimeria bovis and Eimeria zuernii:Feed at a rate to provide 0.14 to 0.42 mg/lb of body weight/day, depending upon severity of challenge, up to a maximum of 200 mg/hd/day. The Type C Medicated Feed must contain 15 to 400 g/ton of monensin (90% DM basis).

For calves (excluding veal calves)
For the prevention and control of coccidiosis due to Eimeria bovis and Eimeria zuerniiFeed at a rate of 0.14 to 1.00 mg/lb of body weight/day, depending upon severity of challenge, up to a maximum of 200 mg of monensin/hd/day. The monensin concentration in Type C medicated feed must be between 10 and 200 g/ton.
