There is disclosed a stable animal feed supplement suspension which is prepared by forming a stable liquid gel in concentrated food industry by-products such as by-products of the dairy industry, such as whey permeates, delactosed whey, and by-products of the fermentation industry, such as whey and corn sweet water. These by-products have not been used with any significant success in animal feed supplements, despite their low cost and disposal problems. A major disadvantage is their limited solubility, and the resultant instability of concentrates of the by-products. The invention comprises the treatment of the protein-rich by-products with a mild enzymatic treatment which stabilizes the by-products against protein gelation, and the thermal, and/or enzymatic treatment of the lactose-rich by-products to avoid separation of the lactose from concentrates. The by-products can then be concentrated to high solids content, in excess of 50 weight percent, and the resultant concentrates can be treated with gelation agents, preferably phosphoric acid and lime to form stable liquid gels, to which feed nutrients such as fats, urea, sodium bicarbonate, calcium carbonate, calcium sulfate, etc., or drugs such as monisan, can be added, forming a stable liquid suspension which is useful as an animal feed supplement.

Methods for producing a stable fat suspension feed supplement

A method of producing non-hygroscopic solids from aqueous food solutions of sugars and proteins by mixing an aqueous solution which contains at least 45 weight percent solids comprising at least 20 percent of protein or sugar or mixtures thereof with additives comprising calcium oxide or hydroxide and a soluble phosphate. The resultant mixture is then dried by evaporation to reduce its moisture content to less than twelve weight percent. Depending on the intended use of the product, the mixture can be formed or shaped into the desired form and then dried, or the mixture can be dried and comminuted to produce a free-flowing granular product.

Method of making non-hygroscopic sugar and protein solids

There is disclosed a stable thixotropic suspension of water insoluble animal feed nutrients in an aqueous feed solution and a method for its preparation. The method comprises forming a liquid gel from an aqueous solution of sugar, protein or mixtures thereof, having a concentration of at least 60.degree. Brix, by adding calcium hyroxide and phosphoric acid or ammonium polyphosphate to the solution. The gel is diluted with water and insoluble feed nutrients such as fat, calcium carbonate, calcium sulfate, etc., or drugs such as monisan are suspended in the diluted gel. Water soluble feed nutrients such as urea, sodium bicarbonate, etc., can also be added.

Thixotropic feed supplement suspensions

There is disclosed a stable thixotropic suspension of a fat in an aqueous liquid gel of a feed solution and a method for its preparation. The method comprises forming the liquid gel from a solution of sugar, protein or mixtures thereof, by incorporating ammonium phosphate in the solution in an amount sufficient to form the gel, adding water to reduce the concentration of the gel, and then adding fat. When fats with solidification temperatures above ambient temperature are added, the liquid gel is warmed to about the melting point of the fat and the fat is melted before mixing the fat with the liquid gel. Other water insoluble feed nutrients such as calcium carbonate, calcium sulfate, etc., or drugs such as monisan can also be suspended in the resultant gel. Water soluble feed nutrients such as urea, sodium bicarbonate, etc., can also be added.

Stable fat suspension feed supplement

A method of making a free choice feed block solidified with calcium hydroxide, etc. which is improved by incorporating a 2 to 20% protein meal and 16-20% of a solid filler of brans, hulls and shells to produce a solid hardness of from 35-60. The presence of the protein meal and filler increases the hardness of the feed block.

Animal feed supplement with filler and method of preparing the same

A buffer containing, solid, animal feed supplement which has the proper hardness and palatibility to achieve a daily animal consumption of 0.2-0.5 pound of sodium carbonate or bicarbonate and 0.07-0.15 pound of magnesium oxide with free choice feeding. The feed supplement is a solidified mixture of various feed ingredients with a feed solution of sugars or proteins, and mixtures thereof. The supplement is solidified by sodium carbonate, or a mixture thereof, and magnesium oxide.

Buffered animal feed supplement block

There is disclosed a new soft, moist pet food and a method for its manufacture. The pet food has a high moisture content, 25 to 50 weight percent, and contains two major nutrient ingredients which are: a protein source, such as a meat meal; and a sugar, each of which is used in an amount from 12 to about 35 weight percent on a dry weight basis. The pet food is prepared by mixing the protein source with an aqueous alkaline ingredient and the sugar to obtain a viscous, intimately admixed sol. The sol is then neutralized to a mildly acidic pH value and the resulting mixture is poured into containers in which it solidifies in a period of several hours, reaching most of its ultimate firmness in approximately 24 hours.
