Even with the recent increase in mineral prices, especially the cost of phosphorus, $10,000 in mineral costs for 100 head of cows is out of line. Mineral needs for a cow herd vary greatly across the United States, and even from ranch to ranch within the same state. You could mix your own mineral, but for a small cow/calf producer, this may not be economical. Adding protein to the mineral mix will only increase the cost, as the mineral will be more palatable, thereby increasing intake. Contact the Cooperative Extension office in your state. They can put you in contact with your state beef specialist. They will have a better understanding of the cows' mineral needs in your location. They will also have an understanding of the mineral profile of the grasses in the area, and this will aid you in developing an economical program for your cow herd. Minerals are important for the cow herd. Salt should always be made available. If your cows are in an area that is prone to grass tetany, then strategic supplementation of magnesium is important. Outside of that, mineral needs of cows vary depending on the mineral profile of the forage being consumed.
