Abstract
Abstract A pallet is provided for farrowing pens and structured to prevent the sow from crushing newborn piglets. The pallet comprises an enthickened central portion having a flat upper surface and laterally sloping side panels extending downwardly and outwardly from the upper longitudinal edges of the central portion. Heating means are provided along the lower longitudinal edge of each side panel and the heating means is insulated from direct contact with the pallets. The heat attracts the piglets away from the sow and the insulation maintains the enthickened central portion at the ambient temperature of the farrowing pen for the sow's comfort.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
140 words
In an animal shelter for newborn pigs wherein there is provided a plurality of farrowing pens arranged in opposing rows, each farrowing pen having a crate for confining a sow therein and a perimeter fence spaced from opposite sides of the crate and joined thereto for confining a newborn litter of pigs and wherein there is further provided a center aisle disposed between said opposing rows for access to the farrowing pens, the combination therewith of (a) a pallet in each farrowing pen and each said pallet including an central portion having a flat upper surface and a pair of side panels sloping downwardly and away from the central portion; (b) a heating pad extending along the lower longitudinal edge of each sloping side panel; and (c) insulating means supporting the heating pad out of direct contact with the pallets.
Claim 2
Dependent Claim
140 words
In an animal shelter for newborn pigs wherein there is provided a plurality of farrowing pens arranged in opposing rows, each farrowing pen having a crate for confining a sow therein and a perimeter fence spaced from opposite sides of the crate and joined thereto for confining a newborn litter of pigs and wherein there is further provided a center aisle disposed between said opposing rows for access to the farrowing pens, the combination therewith of (a) a pallet in each farrowing pen and each said pallet including an central portion having a flat upper surface and a pair of side panels sloping downwardly and away from the central portion; (b) a heating pad extending along the lower longitudinal edge of each sloping side panel; and (c) insulating means supporting the heating pad out of direct contact with the pallets.
Claim 3
Dependent Claim
124 words
In a farrowing pen having a perimeter fence to confine piglets and a farrowing crate within the perimeter fence to confine a mother sow while allowing the piglets free access to and from the sow through the crate, a pallet including a central portion with a flat upper surface conforming to the shape and dimensions of the farrowing crate and extending therebeneath, means connecting the crate to the pallet, and a pair of side panels sloping downwardly and away from the central portion and beyond the juncture of the crate and the pallet and toward the perimeter fence, whereby the piglets move down the sloping side panels to avoid being injured by the sow and move up the side panels to nurse the sow.
Claim 4
Dependent Claim
124 words
In a farrowing pen having a perimeter fence to confine piglets and a farrowing crate within the perimeter fence to confine a mother sow while allowing the piglets free access to and from the sow through the crate, a pallet including a central portion with a flat upper surface conforming to the shape and dimensions of the farrowing crate and extending therebeneath, means connecting the crate to the pallet, and a pair of side panels sloping downwardly and away from the central portion and beyond the juncture of the crate and the pallet and toward the perimeter fence, whereby the piglets move down the sloping side panels to avoid being injured by the sow and move up the side panels to nurse the sow.
Claim 5
Dependent Claim
30 words
A structure according to claim 2 wherein the sloping side panels have lower edges and wherein heating means are provided only along the lower edges of the sloping side panels.
Claim 6
Dependent Claim
19 words
A structure according to claim 3 wherein means are provided for thermally insulating the heating means from the pallet.
Claim 7
Independent Claim
68 words
A method of protecting newborn piglets which comprises the steps of confining the mother sow at a first elevation, providing heating means at a second elevation beneath said first elevation and spaced laterally from the confined sow to attract the piglets and warm them, and providing sloping means extending between said first elevation and the second elevation to provide free access for the piglets between the two elevations.
Claim 8
Independent Claim
68 words
A method of protecting newborn piglets which comprises the steps of confining the mother sow at a first elevation, providing heating means at a second elevation beneath said first elevation and spaced laterally from the confined sow to attract the piglets and warm them, and providing sloping means extending between said first elevation and the second elevation to provide free access for the piglets between the two elevations.
Claim 9
Dependent Claim
20 words
A method according to claim 5 which includes the step of thermally insulating the heating means from the confined sow.
Claim 10
Dependent Claim
94 words
In a farrowing pen having a farrowing crate to confine a mother sow and a perimeter fence spaced from the crate to confine the baby piglets, a pallet including a central portion with a flat upper surface and a pair of side panels each sloping downwardly and away from the central portion providing an area to contain said piglets and each including a lower longitudinal edge, a heating pad extending along the lower longitudinal edge of each sloping side panel, and insulating means supporting the heating pad out of direct contact with the pallet.
Claim 11
Dependent Claim
94 words
In a farrowing pen having a farrowing crate to confine a mother sow and a perimeter fence spaced from the crate to confine the baby piglets, a pallet including a central portion with a flat upper surface and a pair of side panels each sloping downwardly and away from the central portion providing an area to contain said piglets and each including a lower longitudinal edge, a heating pad extending along the lower longitudinal edge of each sloping side panel, and insulating means supporting the heating pad out of direct contact with the pallet.
