Directions For Use
Read All Directions Carefully Before Mixing and Feeding
Active Drug Ingredients: Monensin, USP, 90.7 g per pound.
I. Cattle fed in confinement for slaughter:
A. For improved feed efficiency. Feeding Directions: Thoroughly mix Rumensin 90 to make one ton of complete feed that provides 5 to 40 g/ton monensin on a 90% dry matter basis (Table 1). Feed complete feed (5 to 40 g/ton) continuously to growing finishing beef cattle to provide not less than 50 nor more than 480 mg monensin per head per day. No additional improvement in feed efficiency has been shown from feeding monensin at levels greater than 30 g/ton (360 mg monensin per head per day).
B. For the prevention and control of coccidiosis due to Eimeria bovis and Eimeria zuernii.
Feeding Directions: Feed continuously (10 to 40 g/ton) to provide 0.14 to 0.42 mg per pound of body weight per day, depending upon severity of challenge, up to a maximum of 480 mg of monensin per head per day.
II. Dairy Cows:
A. For increased milk production efficiency (production of marketable solids-corrected milk per unit of feed intake). Feeding Directions:
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% dry matter basis (Table 2).
Component Feeding Systems (including top dress): Feed continuously to dry and lactating dairy cows a Type C Medicated Feed containing 11 to 400 g/ton monensin (Table 3). The Type C Medicated Feed must be fed in a minimum of 1 pound of feed per cow per day to provide 185 to 660 mg/head/day monensin to lactating cows or 115 to 410 mg/head/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% dry matter basis.
III. Growing cattle on pasture or in dry lot (stocker and feeder and dairy and beef replacement heifers):
A. For increased rate of weight gain. Feeding Directions: Feed at the rate of not less than 50 nor more than 200 mg per head per day in not less than one pound of Type C Medicated Feed; or after the 5th day, feed at the rate of 400 mg per head per day every other day in not less than 2 pounds of Type C Medicated Feed. The monensin concentration in the Type C Medicated Feed must be between 25 and 400 grams per ton. During the first 5 days, cattle should receive no more than 100 mg per day contained in not less than 1 pound of feed. Do not self feed.
B. For the prevention and control of coccidiosis due to Eimeria bovis and Eimeria zuernii.
Feeding Directions: Feed at a rate to provide 0.14 to 0.42 mg per pound body weight per day, depending upon severity of challenge, up to a maximum of 200 mg per head per day. The monensin concentration in Type C Medicated Feed must be between 25 and 400 g/ton (Table 1). During the first 5 days, cattle should receive no more than 100 mg per day contained in not less than 1 pound of feed.
C. Free-Choice (Self-Fed) Medicated Feeds.
All Free-choice medicated feeds must provide not less than 50 nor more than 200 mg monensin per head per day. (1) Free-choice medicated feeds manufactured from a published formula and/or specifications do not require a Medicated Feed Mill License. (2) Other manufacturers of Type C free choice feeds with a proprietary formula and/or specifications require an FDA approved Medicated Feed Mill License.
IV. Mature Reproducing Beef Cows (on pasture or in dry lot):
A. For improved feed efficiency when receiving supplemental feed. Feeding Directions: Feed continuously at a rate of 50 to 200 mg per head per day. Blend into a minimum of 1 pound of Type C Medicated Feed and either hand feed or mix into the total ration. Feed (other than the Type C Medicated Feed containing Rumensin) can be restricted to 95% (of normal requirements) when 50 mg of monensin activity is fed, and to 90% at 200 mg. Cows on pasture or in dry lot must receive a minimum of 1 pound of Type C Medicated Feed per head per day. Additionally, a minimum of 16 pounds (air-dry basis) of roughage such as silage, haylage, ammoniated straw, hay or equivalent feedstuffs should be fed in order to meet NRC recommendations for mature reproducing beef cows to gain 0.25 to 0.75 pounds per head per day. Standing, dried winter range forage may not be of adequate quality to result in improved efficiency when supplemented with Rumensin. During the first 5 days, pastured cattle should receive no more than 100 mg per day contained in not less than 1 pound of feed. Do not self feed.
B. For the prevention and control of coccidiosis due to Eimeria bovis and Eimeria zuernii.
Feeding Directions: Feed at a rate of 0.14 to 0.42 mg per pound of body weight per day, depending upon severity of challenge, up to a maximum of 200 mg per head per day. During the first 5 days, pastured cattle should receive no more than 100 mg per day contained in not less than 1 pound of feed.
V. Goats:
A. For prevention of coccidiosis caused by Eimeria crandallis, Eimeria christenseni and Eimeria ninakohlyakimovae.
Feeding Directions: Feed complete feed (20 g/ton) continuously to goats as the sole ration (Table 1). Feed only to goats maintained in confinement.
VI. Calves (excluding veal calves):
A. For the prevention and control of coccidiosis due to Eimeria bovis and Eimeria zuernii.
Feed at a rate of 0.14 to 1.00 mg per pound of body weight per day, depending upon severity of challenge, up to a maximum of 200 mg of monensin per head per day. The monensin concentration in Type C Medicated Feed must be between 10 and 200 g/ton (Table 1).
VII. Type B or C Medicated Feed Mixing Directions (Dry and Liquid):
A. Dry or Liquid
Thoroughly mix the following amounts of Rumensin 90 to make one ton of Type B or C Medicated Feed to provide the levels shown in Table 1. Dry Only - An Intermediate blending step should be performed to ensure an adequate mix.
B. Liquid Limitations
1. The supplement pH must be between 4.3 - 7.1.
2. Stored liquid Type B Medicated Feeds containing Rumensin: For liquid feeds stored in recirculating tank systems: Recirculate immediately prior to use for not 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.
Rumensin 90 Caution
Inadequate mixing (recirculation or agitation) of monensin Liquid Type B or C Medicated Feeds has resulted in increased monensin concentration which has been fatal to cattle and could be fatal to goats. • If feed refusals containing monensin are fed to other groups of cattle, the concentration of monensin in the refusals and amount of refusals fed should be taken into consideration to prevent monensin overdosing.
Directions for Use: Read All Directions Carefully Before Mixing and Feeding
