Calf pens are a necessary part of any well-planned calf house. Individual calf pens have two plastic stepper slats making the pens more hygienic, easier to clean and more comfortable for the calf. These calf pens have a press-steel plate side and front that is hot dip galvanized. The hinged front gate provides easy access to the calf. The pen is quick to assemble and dismantle and fold up neatly for easy storage. They provide superior comfort for the animal and makes it easy to control newborn calves. These ODEL calf pens comply with new EC directives on calf penning.
