For feeding straight mineral I have switched to Vigortone mineral.
I am useing a protien supplement that has Canola meal, salt, mineral and canola oil. It is a bit of a switch from the product I had been useing that had more ingredients such as soy and others but this last mix was the cheapest. It is not Vigortone mineral in it but the mix was made at COOP feeds in Weyburn. I put it out in tubs and aim for 1lb/hd/day. I am not sure that is quite where were at but only put out that much. The cows are out grazing dry native grass and looking great. It has been a great fall and I weaned early. I think if the cows were up closer and needed feed it might not be as economical but only going out every 3 or 4 days sure save fuel time and gets some parts of the ranch used that don't get used other times.
Canola 680kg
Salt 300kg
Can. oil 10kg
1:1 min 10kg
That's canola meal.
