How fast can it kick in and make a difference? I bought some breds and pairs 8 days ago. The two pairs weren't milking much at all. One has a two week old calf the other I'd guess 35-40 days old. The older calf is pot bellied and you can tell it's not had much milk. I gave the Multimin and wormed with dectomax on 12/23 and left town for Christmas getting back last night 12/25. Was off today and got to watch the cows a bunch today. I can't tell any difference in how much the cows are milking but the calves have nursed lioe crazy all day. The first 5 days I had these cows I saw each calf nurse one time each. Can Multimin make a difference that quick?
