Abstract
Abstract Fermented ammoniated condensed whey (FACW) is solidified by mixing it with certain calcium salts and allowing the mixture to stand. The mixture, while still liquid, may be mixed with grains, roughage and forage materials, or it may be shaped into blocks, cubes or pellets. Solidified FACW can be used as a feed supplement for ruminant animals. During the solidification calcium ammonium lactate is formed which is a new crystalline chemical composition. Calcium ammonium lactate (CAL) may be prepared in purified form from lactic acid, calcium hydroxide and ammonia. CAL is useful independently as a feed supplement for ruminant animals.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
74 words
A method of producing a ruminant feed containing solidified fermented ammoniated condensed whey which method consists essentially of mixing fermented ammoniated condensed whey containing 35-55% ammonium lactate with an effective amount of a calcium salt of a strong mineral acid selected from the group consisting of calcium chloride, calcium sulfate and calcium phosphate to cause the solidification of said fermented ammoniated condensed whey, and allowing the resulting mixture to stand until it has solidified.
Claim 2
Independent Claim
74 words
A method of producing a ruminant feed containing solidified fermented ammoniated condensed whey which method consists essentially of mixing fermented ammoniated condensed whey containing 35-55% ammonium lactate with an effective amount of a calcium salt of a strong mineral acid selected from the group consisting of calcium chloride, calcium sulfate and calcium phosphate to cause the solidification of said fermented ammoniated condensed whey, and allowing the resulting mixture to stand until it has solidified.
Claim 3
Dependent Claim
15 words
A method as set forth in claim 1 in which said salt is calcium chloride.
Claim 4
Dependent Claim
31 words
A method as set forth in claim 1 in which the amount of calcium salt added is sufficient to provide 6-10% calcium, based on the weight of fermented ammoniated condensed whey.
Claim 5
Dependent Claim
24 words
A method as set forth in claim 1 in which the mixture is solidified in a mold to produce a protein supplement lick block.
Claim 6
Dependent Claim
40 words
A method as set forth in claim 1 including the step of mixing said mixture with forage, roughage or other plant products suitable for ruminant feeding, whereby solidified fermented ammoniated condensed whey functions as a binder for said plant material.
Claim 7
Dependent Claim
40 words
A method as set forth in claim 1 including maintaining said mixture above a temperature at which it can solidify, placing said mixture in a solidification mold while it is above said temperature, and then allowing said mixture to cool.
Claim 8
Dependent Claim
15 words
A method as set forth in claim 1 including extruding said mixture before it solidifies.
Claim 9
Independent Claim
103 words
A method of producing a ruminant feed containing solidified fermented ammoniated condensed whey which method consists essentially of mixing fermented ammoniated condensed whey with an alkaline calcium compound which is reactive with a strong mineral acid to form a calcium salt of said strong mineral acid, adding a strong mineral acid selected from the group consisting of hydrochloric acid, sulfuric acid and phosphoric acid to react with said compound to form said calcium salt, the amount of said calcium salt formed being effective to cause solidification of said fermented ammoniated condensed whey, and allowing the resulting mixture to stand until it has solidified.
Claim 10
Independent Claim
103 words
A method of producing a ruminant feed containing solidified fermented ammoniated condensed whey which method consists essentially of mixing fermented ammoniated condensed whey with an alkaline calcium compound which is reactive with a strong mineral acid to form a calcium salt of said strong mineral acid, adding a strong mineral acid selected from the group consisting of hydrochloric acid, sulfuric acid and phosphoric acid to react with said compound to form said calcium salt, the amount of said calcium salt formed being effective to cause solidification of said fermented ammoniated condensed whey, and allowing the resulting mixture to stand until it has solidified.
Claim 11
Dependent Claim
27 words
A method as set forth in claim 8 in which said calcium compound is selected from the group consisting of calcium carbonate, calcium oxide and calcium hydroxide.
Claim 12
Dependent Claim
31 words
A method as set forth in claim 8 in which the amount of calcium compound added is sufficient to provide 6-10% calcium, based on the weight of fermented ammoniated condensed whey.
Claim 13
Dependent Claim
24 words
A method as set forth in claim 8 in which the mixture is solidified in a mold to produce a protein supplement lick block.
Claim 14
Dependent Claim
40 words
A method as set forth in claim 8 including the step of mixing said mixture with forage, roughage or other plant products suitable for ruminant feeding, whereby solidified fermented ammoniated condensed whey functions as a binder for said plant material.
Claim 15
Dependent Claim
34 words
A method as set forth in claim 8 including maintaining said mixture above a temperature at which it can solidify, and placing said mixture in a solidification mold while it is above said temperature.
Claim 16
Dependent Claim
15 words
A method as set forth in claim 8 including extruding said mixture before it solidifies.
