Great product

Purina makes wonderful minerals for cattle! My cows are my pets and I’m always trying to find the best diet for them. I’ve never been disappointed with Purina’s

Purina makes wonderful minerals for cattle! My cows are my pets and I’m always trying to find the best diet for them. I’ve never been disappointed with Purina’s wind and rain minerals. I feed the high magnesium blend in the summer. My area is known for being low in magnesium so this mineral helps to ensure my cows are getting the support they need. We don’t have the best soil and we don’t irrigate so it’s important I provide my cows with minerals in areas their nutrition is lacking. This mineral has been great for that! It withstands the weather just as it’s advertised. My cows constantly lick at it so it must taste good or they just know they need the extra mineral support!

Bad delivery

my last two orders from Chewie were left, sitting in the ground by the highway, as opposed to where they normally put it up on my pump house behind the g grain
