STORM LAKE, Iowa (AP) _ Brad Eddie knows how to raise some pricey pork.

A purebred Yorkshire boar he raised on a family hog farm in northwestern Iowa sold for $52,000 at a recent auction in Lubbock, Texas.

``It was the biggest thrill of my life,'' Eddie said Monday, noting that such a sale typically brings an average of $1,500 to $2,000. ``It doesn't get any better than that.''

What made Eddie's 7-month-old, 325-pound boar so valuable was its high ``expected progeny deviation,'' a statistical formula used to calculate a boar's offspring-producing potential.

``The boar is just a very good individual with very good performance,'' he said. ``He's big, he's heavy muscled and wide-walking and really lean.''
