Things You'll Need
- Ivermectin
- Needleless syringe, or dosing gun
Instructions
Buy cattle strength injectable ivermectin. There are two brand names for the product: Ivomec, a 1 percent sterile ivermectin solution for cattle and swine made by Merck, and Double Impact, a 1 percent sterile ivermectin solution for cattle and swine by Agrilabs. The products come in injectable and pour-on methods, and are marked that way on their labels.
Use 1 milliliter per 50 pounds of animal of the injectable types of ivermectin. Give 1 milliliter per 10 pounds of animal of the pour-on types. Ivomec comes in 50 milliliter and 200 milliliter---buy the volume closest to the amount you need for your herd, but the product stores well as long as you keep it in a cool, dry place.
Give the Ivomec orally; inject the dosage into the side of the mouth with a needleless syringe, or dosing gun. The product is labeled for injection, but it works better in goats and sheep when given by mouth. Pour-on ivermectin products work the same way, and are given orally to goats and sheep.
Use Ivomec Plus if you suspect liver flukes (a type of worm that invades the liver). Dose at 1 milliliter per 50 pounds and give orally.
