ABSTRACT:
A protected feeder is provided for livestock which comprises a receptacle with an open top supported at a selected position above a ground surface and adapted to contain a livestock attracting material therein, such as feed, salt or a mineral. A flexible cover member with a marginal portion which extends substantially beyond the top edge of the receptacle is mounted on the support structure in covering relation to the open top of the receptacle and livestock are permitted to contact the marginal portion from underneath and displace a portion of the cover member upwardly to gain access to the livestock attracting material in the receptacle. The cover member has unsupported portions which tend to sag downwardly and arcuate access openings between its marginal portion and the top edge of the receptacle through which livestock can see and smell the attracting material and are encouraged to lift the cover member at the openings, although access can be had from anywhere around the receptacle. The cover member is substantially impervious and protects the livestock attracting material from weather and from contamination.
