Abstract
Abstract A poultry litter is disclosed in two preferred embodiments: compacted peat in fragments ranging in nominal diameter from 1/8 of an inch to 11/2 inches, and compacted peat fragments combined with a conventional litter material such as wood shavings, with the peat accounting for at least ten percent of the mixture weight. In this latter case, the peat fragments preferably have nominal diameters no greater than 1/8 of an inch. Preferably the peat is of the reed sedge type, with a pH of from 3.5 to 4.5, and a moisture content of no more than fifty percent by weight. For enhanced capacity to absorb moisture and dust control, the peat fragments are provided with a coating of a feed grade petroleum based oil, vegetable oil or animal fat.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
78 words
A poultry litter for use in confined enclosures, consisting essentially of: compacted to a density to reduce formation of duct when agitating or otherwise disturbing the peat, said peat being peat size and formed into fragments of random size and shape and with nominal diameters from about 1/8 of an inch to of less than about 13/4 inches, said fragments having a pH of less than seven and a moisture content of at most fifty percent by weight.
Claim 2
Dependent Claim
78 words
A poultry litter for use in confined enclosures, consisting essentially of: compacted to a density to reduce formation of duct when agitating or otherwise disturbing the peat, said peat being peat size and formed into fragments of random size and shape and with nominal diameters from about 1/8 of an inch to of less than about 13/4 inches, said fragments having a pH of less than seven and a moisture content of at most fifty percent by weight.
Claim 3
Dependent Claim
23 words
The poultry litter of claim 1 wherein: said fragments have nominal diameters ranging from about 1/8 of an inch to about 11/2 inches.
Claim 4
Dependent Claim
21 words
The poultry litter of claim 2 wherein: said peat is reed sedge peat and has a pH of less than 5.5.
Claim 5
Dependent Claim
20 words
The poultry litter of claim 3 wherein: said peat has a pH within the range of from 3.5 to 4.5.
Claim 6
Dependent Claim
44 words
The poultry litter of claim 2 further including: a coating provided over exposed surfaces of said fragments, said coating consisting essentially of at least one of the following components: a feed grade petroleum-based oil, a feed grade vegetable oil, and feed grade animal fat.
Claim 7
Dependent Claim
34 words
The poultry litter of claim 5 wherein: said coating consists essentially of at least one of the following components: mineral oil, propylene glycol, soy oil, corn oil, peanut oil, cotton seed oil, and tallow.
Claim 8
Dependent Claim
72 words
A poultry litter for use in confined enclosures, consisting essentially of: a highly moisture absorbent, high fiber by-product mixture of food processing; and at least ten percent by weight peat compacted to a density substantially above its naturally occurring density to reduce dust formation when disturbing the peat, said peat being formed in fragments having a moisture content of at most fifty percent by weight and a pH of less than seven.
Claim 9
Dependent Claim
72 words
A poultry litter for use in confined enclosures, consisting essentially of: a highly moisture absorbent, high fiber by-product mixture of food processing; and at least ten percent by weight peat compacted to a density substantially above its naturally occurring density to reduce dust formation when disturbing the peat, said peat being formed in fragments having a moisture content of at most fifty percent by weight and a pH of less than seven.
Claim 10
Dependent Claim
38 words
The poultry litter of claim 7 wherein: said by-product mixture consists essentially of one or more of the following high fiber components: wood shavings, saw dust, peanut hulls, oat hulls, sunflower hulls, ground corn cobs, and rice hulls.
Claim 11
Dependent Claim
21 words
The poultry litter of claim 8 wherein: said fragments of peat have nominal diameters of at most 1/8 of an inch.
Claim 12
Dependent Claim
42 words
The poultry litter of claim 9 further including: a coating provided over exposed surfaces of said fragments and consisting essentially of at least one of: a feed grade petroleum based oil, a feed grade vegetable oil, and a feed grade animal fat.
Claim 13
Dependent Claim
33 words
The poultry litter of claim 10 wherein: said coating consists essentially of one or more of the following: mineral oil, propylene glycol, soy oil, corn oil, peanut oil, cotton seed oil, and tallow.
Claim 14
Dependent Claim
94 words
A process of manufacturing an animal litter, including the steps of: compacting peat to a density substantially above its naturally occurring density to reduce dust formation due to disturbing the peat, and drying the peat to reduce its moisture content to at most fifty percent by weight; fracturing the peat into fragments of random size and shape; separating the peat to remove a first group of said fragments having nominal diameters greater than a selected maximum value; and mixing the remaining ones of said fragments to provide a substantially random distribution of said fragments.
Claim 15
Dependent Claim
94 words
A process of manufacturing an animal litter, including the steps of: compacting peat to a density substantially above its naturally occurring density to reduce dust formation due to disturbing the peat, and drying the peat to reduce its moisture content to at most fifty percent by weight; fracturing the peat into fragments of random size and shape; separating the peat to remove a first group of said fragments having nominal diameters greater than a selected maximum value; and mixing the remaining ones of said fragments to provide a substantially random distribution of said fragments.
Claim 16
Dependent Claim
38 words
The process of claim 12 including the further step of: prior to mixing said remaining fragments, further separating the peat to remove a second group of said fragments having nominal diameters of less than a selected minimum value.
Claim 17
Dependent Claim
42 words
The process of claim 13 including the further step of: applying a coating to the surfaces of said fragments, said coating including at least one of the following feed grade constituents: a petroleum based oil, a vegetable oil, and an animal fat.
Claim 18
Dependent Claim
33 words
The process of claim 14 wherein: said coating consists essentially of one or more of the following constituents: mineral oil, propylene glycol, soy oil, corn oil, peanut oil, cotton seed oil, and tallow.
Claim 19
Dependent Claim
27 words
The process of claim 14 further including the further step of: heating said coating to a temperature of at least 75° F. prior to applying said coating.
Claim 20

Claim 21
Dependent Claim
21 words
The process of claim 13 wherein: said maximum value is 11/2 inches, and said minimum value is 1/8 of an inch.
Claim 22
Dependent Claim
33 words
The process of claim 12 including the further step of: combining said fragments in said random distribution with a highly moisture absorbent, high fiber by-product mixture of food processing in said random distribution.
