ABSTRACT:
A slotted grating is used for forming bases for boxes for suckling sows and piglets, and is of the kind having larger apertures in the areas in which the sows are kept, smaller apertures in the areas in which the piglets are kept, said apertures serving for discharging excrement and urine. The improvement of the invention is that the slotted grating consists of a structural element provided along the length of the box with groups of different apertures respectively of rectangular or round shape, the rectangles or the round holes within each group having the same slot width or diameter, the rectangular apertures or round holes differing in slot width or diameter from group to group.
