A feeding apron is a separate area of concrete used for feeding animals. It is commonly referred to as a feeding row. Because it is used for feeding only, effluent is sometimes managed differently from the sleeping/resting area.
If the feeding row effluent is treated separately from that of the sleeping/resting area then specify a concrete feeding apron. If all the effluent is combined and treated the same, a concrete feeding apron does not need to be selected.
