Monensin Premix Indications
Broiler chickens and growing turkeys:
1. As an aid in the prevention of coccidiosis caused by Eimeria acervulina, E. mitis, E. necatrix, E. maxima, E. tenella, and E. brunetti in broiler chickens.
2. As an aid in the prevention of coccidiosis caused by Eimeria adenoeides, E. meleagrimitis and E. gallopavonis in growing turkeys.
1. For improved feed efficiency in beef cattle (steers and heifers) fed in confinement for slaughter.
2. As an aid in the prevention of coccidiosis caused by Eimeria bovis and Eimeria zuernii. Note to user: Coccidiosis occurs sporadically in first lactation dairy heifers, but is not considered a significant disease in mature dairy cows.
3. For increased rate of weight gain in growing cattle on pasture (slaughter, stocker and feeder cattle, and beef and dairy replacement heifers) of greater than 180 kg (400 lb) body weight.
4. For reduction of milk fat percentage in lactating dairy cows.
5. For minimizing loss of body condition during lactation in dairy cows.
6. For improving feed efficiency of milk protein production in lactating dairy cows.
Dosage and Administration
Important - must be thoroughly mixed in feeds before use.
Broiler chickens and growing turkeys:
Thoroughly mix 500 g (0.50 kg) of MONENSIN premix in one metric tonne (1000 kg) of feed to provide monensin at 100 g monensin activity per metric tonne of feed. It is recommended that MONENSIN premix be mixed with a small quantity of one of the feed ingredients before it is incorporated in the finished feed.
Broiler chickens - feed the medicated feed continuously as the sole ration.
Growing turkeys - feed continuously as the sole ration.
Complete diet - which includes complete feed plus roughage:
For indications 1, 2, 3, 4, 5 and 6: MONENSIN premix can be mixed in dry supplement prior to final mixing.
For indications 1 and 2: MONENSIN premix can be used in the following thixotrope liquid supplements: Promolas Liquid Supplement Suspension, Westway Feed Products, A Division of Westway Holdings Canada Inc.
Indication 1: Option A) Feed continuously at a rate of not less than 33 g and not more than 48 g monensin activity per tonne (1,000 kg) until animals reach market weight. Mix not less than 165 g and not more than 240 g MONENSIN premix per tonne (1,000 kg) (to provide not less than 33 g and not more than 48 g monensin activity) to market weight.
Note: The data used to support a claim for feed efficiency for a dose range of 33 to 48 ppm was derived from a meta-analysis, including 11 studies and more than 11,000 animals. This analysis demonstrated an additional improvement in feed efficiency of 0.05 units on a “deads out” basis in cattle fed 48 ppm when compared with those fed 33 ppm. In some herds, no additional improvement in feed efficiency was shown from feeding monensin at levels greater than 33 ppm. Decisions on the appropriate dose of MONENSIN premix should be made in consultation with your veterinarian.
Option B) Feed continuously at a rate of 33 g monensin activity per tonne (1,000 kg) until animals reach market weight. Mix 165 g of MONENSIN premix per tonne (1,000 kg).
Option C) Feed continuously at an initial rate of 11 g monensin activity per tonne for the first 28 days followed by 33 g of monensin activity per tonne (1,000 kg) until animals reach market weight. Mix 55 g MONENSIN premix per tonne (1,000 kg) for the initial 28 days then mix 165 g MONENSIN Premix per tonne (1,000 kg).
Indication 2: Feed continuously at a rate of 22 g monensin activity per tonne (1000 kg) during periods of exposure to coccidiosis or when coccidiosis is likely to be a hazard. Mix 110 g MONENSIN premix per tonne (1000 kg).
Indication 4: Feed continuously at a rate of 16 - 24 g monensin activity per tonne (1000 kg).
NOTE: The expected efficacy of this product for reduction of milk fat percentage may be affected by dietary factors. Reduced efficacy may be expected with diets higher in fibre or lower in unsaturated oils.
Indication 5: Feed continuously at a rate of 8 - 24 g monensin activity per tonne (1000 kg).
Indication 6: Feed continuously at a rate of 16 - 24 g monensin activity per tonne (1000 kg).
While inclusion of the drug in the total daily diet is ideal, it is sometimes necessary to supply the drug via a premix or supplement.
Medicated supplement/premix fed as a % of total diet dry matter:
Mixing medicated supplements or premixes as a % of total diet dry matter is ideal. The following calculation can be used to assist in determining the amount of monensin activity required per kg of supplement/premix dry matter to meet the approved level of drug in the total diet dry matter;
mg monensin/kg supplement/premix dry matter =
approved drug level (mg/kg total diet Dry Matter) x 100
(% supplement/premix of total diet dry matter)
Medicated supplement/premix fed as a fixed amount/head/day:
It may sometimes be preferable to mix the medicated supplement/premix in the complete feed or total diet as a fixed amount/head/day. The approved levels of monensin sodium (i.e. mg/kg of total diet dry matter) must be converted to mg/head/day to accommodate this type of feeding. To do this the following calculation is used:
mg/head/day = weight of animal (kg) x dry matter intake (% of body weight) x approved drug level (mg/kg total diet Dry Matter).
This calculation has been made for a wide range of body weights, using six different dry matter intake levels and is available from the manufacturer. These calculations represent the correct levels of monensin sodium required per head per day for a given body weight.
Medicated complete feeds:
Medicated complete feeds are often fed separately from the forage part of the ration on a fixed amount/head/day. The approved level of monensin activity must be converted to mg/head/day to accommodate this type of feeding. To do this, the following calculation is used:
mg monensin/head/day = weight of animal (kg) x dry matter intake (% of body weight) x approved drug level (mg/kg total diet Dry Matter).
Indication 3: Hand feed at 200 mg of monensin activity per head per day in medicated supplement. The medicated supplement must be prepared so that when it is hand fed as directed, at a minimum of 0.5 kg/head/day, it provides 200 mg of monensin activity per head per day. For example, if the medicated supplement is to be hand fed at 0.5 kg per head per day, it must have 2 kg of MONENSIN premix added to it per 1000 kg of supplement. The medicated supplement must be hand fed from the beginning to the end of the pasture season.
NOTE: Thixotrope liquid supplements should not be used for hand feeding of cattle on pasture.
1. All rations should be corrected to a 100% DRY MATTER BASIS.
2. For intermediate blending of secondary premixes and/or supplements and the use of dry or thixotrope liquid supplements, to provide the required dosages, see the information available from the manufacturer.
3. All secondary premixes and supplements must be thoroughly mixed in the total diet or in complete feed (grain portion of the ration) before use. Do not feed undiluted.
4. Consult your veterinarian and/or nutritionist for additional information regarding the use of monensin in lactating dairy cattle.
1. Do not feed to replacement and laying chickens or turkeys.
2. For indications 1, 2 and 3 (beef cattle): Do not supplement monensin from other sources (e.g. other feedstuffs containing monensin or other slow release devices containing monensin).
3. For indications 4, 5 and 6 (dairy cattle): Do not supplement MONENSIN premix above 16 ppm to dairy cows in herds administered slow release devices containing monensin.
4. When mixing and handling MONENSIN premix, use protective clothing, impervious gloves and a dust mask. Operators should wash thoroughly with soap and water after handling.
5. No pre-slaughter withdrawal (beef cattle, broiler chickens and growing turkeys) or milk withholding time is required when this drug product is used according to the label directions.
6. Keep out of reach of children.
1. Do not use MONENSIN premix for treatment of outbreaks of coccidiosis.
2. Do not exceed recommended levels as reduced average daily gains may result.
3. Do not allow canines, horses or other equines, or guinea fowl access to formulations containing monensin. Ingestion of monensin by these species has been fatal.
4. May be used in feeds containing the pellet binding agents bentonite (2%), Attapulgite (2%), Kaolin (2.5%), Lignin Sulfonate (4%), Carboxy Methylcellulose (0.1%) or Agri-Colloid.
5. Poultry consuming monensin should not be treated with products containing tiamulin. Severe growth depression may occur.
6. Some species of turkey coccidia may be monensin tolerant.
7. NOT TO BE USED AFTER EXPIRATION DATE. Do not use thixotropic supplement after eight weeks storage (Westway Feed Products).
8. The 24 g/tonne monensin treatment in primiparous cows may result in the increased incidence of udder edema and increased number of inseminations per full term conception.
9. The continuous use of monensin in dairy cows may be associated with increased rates of twinning and stillbirths, and heavier birth weights for heifer calves.
StorageStore in a cool, dry place below 30° C. Keep from freezing.
