Comfy Calf Suites are customizable pens consisting of easy-to-remove-and-clean plastic side panels plus front and/or back spindle gates. System benefits: cleaner/drier pens, increased labor efficiency, easier observation of calves, better air movement, reduced disease-transmission risk, easier/safer feeding, and easy pen entry because of the gate's self-catch latch system. Available in 36-, 42-, and 48-inch-wide standard models and custom-designed models. This product allows one with a mobility, back, or vision impairment to feed and care for calves without having to enter the pens.
