Abstract
Abstract An antiblister mat, particularly adapted for raising broilers in a cage having a mesh floor on which broilers normally cannot be raised blister-free, in which the broilers are installed and breast or keel bone blisters are minimized, in which the mat is substantially resilient and comprises a plurality of openings so dimensioned and arranged as to prevent the breast of the broiler, when sitting, from engaging the mesh floor of the cage, and in which the mat comprises various arcuate or tubular cross sections and in which the mat and cage are readily cleaned and sterilized, and permit manure and the like to drop or pushed by birds'' feet through the cage floor.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
85 words
An antiblister cage mat arrangement for cage-raising broilers and deterring the development of blisters on the keel or breast bone skin or meat of the broilers, comprising in combination with an open mesh cage floor, mat means comprising a body including an outer dimension substantially conforming to and overlying the mesh floor of the cage, said mat means including a generally planar lower surface and a repetitive series of through openings, said openings being defined on at least two sides by marginal, tubular, resilient elements.
Claim 2
Dependent Claim
85 words
An antiblister cage mat arrangement for cage-raising broilers and deterring the development of blisters on the keel or breast bone skin or meat of the broilers, comprising in combination with an open mesh cage floor, mat means comprising a body including an outer dimension substantially conforming to and overlying the mesh floor of the cage, said mat means including a generally planar lower surface and a repetitive series of through openings, said openings being defined on at least two sides by marginal, tubular, resilient elements.
Claim 3
Dependent Claim
38 words
The structure as claimed in claim 1 in which the openings are at least three-fourths inch along one dimension for preventing the breast bone of a normal 4-week-old broiler from engaging the mesh floor beneath the mat means.
Claim 4
Dependent Claim
90 words
An antiblister cage mat arrangement for cage-raising broilers and deterring the development of blisters on the keel or breast bone skin or meat of the broilers, comprising in combination with an open mesh cage floor, mat means comprising a body including an outer dimension substantially conforming to and overlying the mesh floor of the cage, said mat means including a generally planar lower surface and a repetitive series of through openings, said openings being defined on at least two sides by marginal resilient elements which are at least partially tubular.
Claim 5
Dependent Claim
90 words
An antiblister cage mat arrangement for cage-raising broilers and deterring the development of blisters on the keel or breast bone skin or meat of the broilers, comprising in combination with an open mesh cage floor, mat means comprising a body including an outer dimension substantially conforming to and overlying the mesh floor of the cage, said mat means including a generally planar lower surface and a repetitive series of through openings, said openings being defined on at least two sides by marginal resilient elements which are at least partially tubular.
Claim 6
Dependent Claim
30 words
The structure as claimed in claim 3 in which said series of repetitive openings are rectangular and are bordered on all sides by three-dimensional elements having an arcuate cross section.
Claim 7
Dependent Claim
22 words
The structure as claimed in claim 4 in which said bordering elements define a rectangular opening and are semicircular in cross section.
Claim 8
Dependent Claim
14 words
The structure as claimed in claim 4 in which said bordering elements are tubular.
Claim 9
Dependent Claim
17 words
The structure as claimed in claim 6, in which said bordering elements are elliptical in cross section.
Claim 10
Dependent Claim
51 words
The structure as claimed in claim 3, in which said openings are elongated and rectangular in plan, defined by said resilient elements which are in the form of two side ribs extending in substantially mutually parallel relation, the ribs being three-dimensiOnal and connected adjacent the lower margin thereof by transverse straps.
Claim 11
Dependent Claim
30 words
The structure as claimed in claim 8 in which said ribs are arcuate in cross section and said straps are flat, project between the lower edges of the arcuate ribs.
