Sweetpro makes a tub that is efficient to use on cows and for starting calves. THere is a plant in ND and dealer in your area of Canada. We put them out in the late fall for fall calving cows and spring calving cows also. Much more reasonably priced than Crystlix I like the ingredients better.The reason we feed protein this way in the fall for awhile is so we don't have to go to pastures every day. It works good for us,but may not be what you want in your area.
