Mike, I'm no expert on cattle. I'm a farm wife that works close with the hubby in the business. In the past years our cattle have had high yields, We sold on the grid this past 2 weeks for the first time, had a few heavy carcasses but picked up a nice premium on the grade. We were happy. One problem we have encountered is the health of animals that come from very isolated ranches straight to our feedlot. They seem to need extra vaccinations to keep them healthy when exposed to our farm germs. We will pay extra for cattle that have had a good vaccination program on the ranch. I feel that the calves are coming to us with better genetic makeup to produce a great tasting and tender steak. I owe that to the ranchers and their knowlege of perfecting their breeding programs. It is a great life working with the cattle and meeting such nice folks.
