In the corn belt of Kansas, this 18,000 cattle feed yard processing, shipping/receiving, and sorting system has 5 shipping pens, and one fattening pen shown. The fattening and receiving pens has a feed bunk and a 12 foot wide concrete feed apron. Cleaning access gates on the concrete apron open as the apron is cleaned. The feed bunk has an adjustable cable for different sized animals (see website photos). The fattening pen shown slopes 3° from the feed bunk and apron down to the cattle alley and across the alley into a drain ditch sloping from right to left on the drawing. The sort pens and auxiliary holding pens slope 3° in the opposite direction across the cattle alley into the drainage ditch. All the posts in the pen fence and alleys are on 8 foot centers. The posts in the curved fence on 4 foot centers. The grooved concrete floors must be deep for cattle. The book has good tips for concrete, and illustrations for the grooving tools. This facility was designed with solid sided fences beginning in the curved alley, crowd pen, and single file.
