Jeffers does not carry the gel caps I used to copper bolus with. A calf copasure would fill one and 1/2 of another. Valley Vet has the 1/8 oz (1 1/4"x 1/2") gel caps for 14.49 per 100. I am math challenged... :crazy So how many a pounds would a capsule of this size treat? Is there a better source or size to buy?
