“We started using Cal Mate, instead of Bolvikalc, in 2020 and haven’t looked back since. We love our drencher from Drench-Mate and found out they sold calcium boluses with the same make up as the competition, but at a fraction of the price. We also love the plastic packaging they come in, very easy to open and they stay fresh in the vacuumed sealed pouch.”  – Angie Scidmore, Scidmore Dairy

“We have recently been on a downward spiral as far as our cows freshening in specifically and with some metabolic needs. I am so excited to continue moving forward with these products as we have been implementing and seeing the progression we are able to make with these important tools you have allowed us to use here on our farm.”
