An improved livestock antifouling frame is a pedal unit, comprising: a plurality of anti-sliding step tubes, two side frames, two horizontal frames, and a plurality of supporting spacers； a stepping surface is formed on the upper surface of the anti-sliding step tubes； and the supporting spacer has Compartment plate surface, the plate body is provided with a plurality of perforations of different heights, and the perforation is perforated with anti-slip tread tube； the two side frames are opposite to the cross-section shape of anti-slip tread tube, and the corresponding perforation group connection hole is opened for assembly. The holes are connected at both ends of the anti-slip tread tube； two horizontal frames are vertically connected to the side frame, and form a high and low stepping part with a drainage gap together with a plurality of support spacers and a plurality of anti-slip tread tubes. ； In addition to the above structure, in addition to forming the pedal unit that meets the rigid strength requirements, the shape of each anti-skid pedal tube is also consistent, simplifying the structure to facilitate manufacturing and assembly.一種牲畜防污架改良，係一踏板單元，包括：多數個止滑踏管、二側框、二橫框及多數個支撐間隔件；止滑踏管上表面形成有踩踏面；支撐間隔件具有隔間板面，板體設有多個不等高的穿孔，穿孔係穿有止滑踏管；二側框，係相對止滑踏管斷面形狀，開設對應穿孔的組接孔，組接孔係接合在止滑踏管兩端部；二橫框，係垂直地相接於側框，並與多數個支撐間隔件及多數個止滑踏管，共構形成具有排污空隙的高低踩踏部；由上述結構，除能架構形成符合剛性強度要求的該踏板單元外，亦使每一止滑踏管的形狀皆呈一致，達到結構簡易化，以便於製造及組立。
