Genetic selection is often complicated and confusing for many livestock producers. We try to decipher numerous trait measurements. We pour through and try to interpret breeding values and EPDs. We like to use weighted or adjusted values for various traits. In the past couple of decades we have added DNA marker technology to the mix.

We read breed promotion literature, look at the glossy pictures in breed association catalogs, and ask neighbors and friends what they are using. Some of us pay attention to sale barn owners and operators, feedlot managers, the packer or processor, the lender or whoever is selling us something.

The seed for a mechanical hay drier was planted in my mind by an article in the May 2010 issue of Graze. On a visit to northern France, Joel McNair had talked with Jean-Luc Gaugain about his system for drying loose hay.

Jean-Luc’s system captured solar energy from air heated inside the black, steel roof and walls of his barn. This heated air was forced through loose hay to finish the drying process of forages that had been harvested at 30-35% moisture.
