Large feed lot pens are on a 3 degree slope. Three degree slope is 3-feet (1m) per 100-feet (30.5m). This slope is ideal to allow proper drainage, but not too steep that erosion occurs. The slope should extend across the cattle alley at the bottom of the pen to prevent the alley from becoming muddy and difficult to move cattle through. The wind break shed at the top of the pen is on the north side to block the prevailing north wind.
