Unless one has bought the other Moormans and Vita Ferm are two different deals.
MoorMans make minerals and the company that makes VitaFerm is
Biozyme Enterprises out of St. Joe, Mo. http://www.biozymeinc.com. It is an excellent product. Well worth the price.
We have used the cheap brands of mineral in the past. The last two years we switched to moorman's mineral and it has made a great difference. It is well worth the money. The main reason we switched was that 25% of our cows wouldn't clean (pass their afterbirth), that's when we switched and have had to clean a cow since. It is costly, but well worth the money.
