Ingredient: Monensin Premix 20%/40%

Core Indications

Prevention of Coccidiosis

Target Species & Eimeria Strains

Animal Category	Specific Species	Key Eimeria Strains Targeted
Poultry	Broiler Chickens	– Eimeria tenella (cecal coccidiosis, lethal)- E. acervulina (intestinal coccidiosis)- E. maxima (jejunal coccidiosis)- E. necatrix (severe intestinal damage)
Poultry	Turkey Poults	– Eimeria adenoeides (intestinal coccidiosis)- E. meleagrimitis (duodenal coccidiosis)
Ruminants	Beef & Dairy Calves	– Eimeria bovis (intestinal coccidiosis)- E. zuernii (hemorrhagic coccidiosis)
Ruminants	Lambs	– Eimeria ovinoidalis (primary pathogenic strain)- E. crandallis

Growth Promotion (Beef Cattle Only)

In beef cattle (including feedlot cattle and growing calves), Monensin Premix improves feed conversion efficiency (more weight gain per kg of feed consumed) and increases average daily gain (ADG). It achieves this by:

Modulating rumen microbial populations to reduce methane production (less energy wasted as gas).

Promoting the growth of bacteria that produce propionate (a key energy source for cattle), instead of acetate and butyrate.

This indication is exclusive to beef cattle—monensin is not approved as a growth promoter for dairy cattle, sheep, or poultry.

Prohibited Species (Critical!)

Monensin has an extremely narrow safety margin in non-target species; even small doses can cause fatal toxicity. It is strictly forbidden for:

Dairy cows (lactating or dry): Toxic to dairy cattle; also, residues may contaminate milk.

Horses, donkeys, mules: Lethal even at doses as low as 1 mg/kg body weight (signs: colic, muscle tremors, cardiac failure).

Pigs, dogs, cats: Highly toxic; no approved use.

Egg-laying hens (layers): Not approved for coccidiosis prevention in layers (may reduce egg production and cause residue risks).

Dosage

(1) Poultry: Coccidiosis Prevention

Poultry Species	Active Monensin in Feed	Premix Dosage Example (for 20% Monensin Premix)	Duration of Use
Broiler Chickens	90–110 mg/kg feed	0.45–0.55 g/kg feed (450–550 g/ton of feed)	Day 1 of life until 5–7 days before slaughter (withdrawal period).
Turkey Poults	50–60 mg/kg feed	0.25–0.3 g/kg feed (250–300 g/ton of feed)	Day 1 to 12 weeks of life (or until moved to low-risk housing).

(2) Ruminants: Coccidiosis Prevention

Ruminant Species	Active Monensin in Feed	Premix Dosage Example (for 20% Monensin Premix)	Duration of Use
Beef/Dairy Calves	15–30 mg/kg feed	0.075–0.15 g/kg feed (75–150 g/ton of feed)	Start at 2–3 weeks old; continue until 8–12 weeks old (end of high coccidiosis risk).
Lambs	10–20 mg/kg feed	0.05–0.1 g/kg feed (50–100 g/ton of feed)	Start at 2 weeks old; continue until 6 weeks old.

(3) Beef Cattle: Growth Promotion

Beef Cattle Category	Active Monensin in Feed	Premix Dosage Example (for 20% Monensin Premix)	Duration of Use
Growing Calves	20–25 mg/kg DM feed	0.1–0.125 g/kg feed (100–125 g/ton of feed)	Start at weaning; continue until entering the feedlot.
Feedlot Cattle	25–33 mg/kg DM feed	0.125–0.165 g/kg feed (125–165 g/ton of feed)	From arrival at the feedlot until 5–7 days before slaughter.

Withdrawal Period

Animal Species	Withdrawal Period for Meat
Broiler Chickens	5 days
Turkey Poults	7 days
Beef Cattle	5 days
Calves/Lambs	5 days

Never slaughter animals before the withdrawal period ends—violations result in food safety penalties or product recalls.

Storage

Keep in a dry and cool place not exceeding 30℃ and avoid light.
