I picked up a bag of wind and rain by purina with altosid in it to act as an igr. I have 10 angus yearlings, 9 piglets, 3 sheep, and 3 pregnant goats separate but near each other. Right now I only have the wind and rain for the cattle. My first question is, is there a cheaper option that is effective for getting the altosid (or another igr) to the cattle? Wind and rain is about $40/50 lbs near me. Second, is do I need to give an igr to the other animals? If yes, any recommendatiotions? Fourth, is an igr safe for a pregnant goat, if it's needed?
