Table of Recommended Dosages


Approx. 300 lbs.

2.50 oz.


Approx. 600 lbs.

5.00 oz.

Adult Horses

Approx. 900 lbs.

7.50 oz.

For horses over 900 lbs. in weight, increase the dosage proportionately according to the above table.

Treatment: Dose each horse individually. Carefully determine the weight of the animal to be treated and determine the correct dosage. Mix ALFALFA PELLET WORMER thoroughly with the amount of grain the horse will consume in a single feeding. Do not give the horse additional feed that day until the treated feed is fully consumed. Most horses will take the medicated feed readily and should be given plenty of good hay when all grain is consumed. If the horse won't eat the medication, add liquid molasses.

Note: Horses are constantly subject to reinfestation, particularly through grazing in confined pastures. Therefore, periodic worming and good stable sanitation are essential. For the most effective control of internal parasites, use ALFALFA PELLET WORMER every 8-10 weeks.


Store out of direct sunlight.
