This last year I switched from feeding Purina Wind & Rain free choice to Vitalix #1 Conditioner CU Tub.
Vitalix contained all the same minerals (excluding salt) and some others that the wind and rain did not, and included extra magnesium and copper, much needed in my area. It also gave me 21% Protein and 6% Fat to help give my calving/nursing mamas, as well as my calves and finishing steers the extra boost they needed. They ate the tub consistently to the last drop, vs. wasting half of the Wind and Rain.
When I broke the cost down it was only costing me 4¢ more per head per day to feed the tub with little to no waste. Wind & Rain 16¢ per head per day. Vitalix 20¢ per head per day. At first my cattle consumed alot more of the Vitalix tub. It was new and tasted yummy
But after a week or two, their bodies started to get a correct mineral balance, and the consumption dropped. 10 Cows go thru a tub about every 3 months now, so about .2 lbs a day per head.
I am no way associated with vitalix, I am just a happy customer that has seen a huge improvement in my cattle since switching, and I love to see others have the same success that I did!
