Safe-guard wormer (fenbendazole) 500mL liquid
For Horse, Beef and Dairy Cattle: 2.3 mg/lb (5 mg/kg) body weight for the removal and control of: lungworm, stomach worm, brown stomach worm, barberpole worm, small stomach worm, intestinal worm, hookworm, thread-necked intestinal worm, small intestinal worm and bankrupt worm.
The dosing rate for horses is 2.5ml/110lbs so you would need 22.7 ml per 1000lb horse so a 500ml bottle would treat 22 horses at that weight.
Foals are double the dose at 5ml per 110lbs.
Goats: 2.3 mg/lb (5 mg/kg) body weight for the removal and control of stomach worms.
