In some embodiments, ground animal and poultry proteinaceous tissues are mixed with the other ingredients, including fish oils, cereal grains, other nutritionally balancing ingredients, special-purpose additives (e.g., vitamin and mineral mixtures, inorganic salts, cellulose and beet pulp, bulking agents, and the like); and water that is sufficient for processing is also added. These ingredients can be mixed in a vessel suitable for heating while blending the components. Heating of the mixture can be effected using any suitable manner, such as, for example, by direct steam injection or by using a vessel fitted with a heat exchanger. Following the addition of the last ingredient, the mixture can be heated to a temperature range of from about 50° F. (10° C.) to about 212° F. (100° C.). In some instances, the mixture can be heated to a temperature range of from about 70° F. (21° C.) to about 140° F. (60° C.). Temperatures outside these ranges are generally acceptable but may be commercially impractical without use of other processing aids. When heated to the appropriate temperature, the material will typically be in the form of a thick liquid. The thick liquid can be filled into cans. When filled into cans, a lid is applied, and the container is hermetically sealed. The sealed can is then placed into conventional equipment designed to sterilize the contents. This is usually accomplished by heating to temperatures of greater than about 230° F. (110° C.) for an appropriate time, which is dependent on, for example, the temperature used and the composition.
Pet food compositions can alternatively be prepared in a dry form using conventional processes. Typically, dry ingredients, including, for example, animal protein, plant protein, grains, etc., are ground and mixed together. Moist or liquid ingredients, including fats, oils, animal protein, water, etc., are then added to and mixed with the dry mix. The mixture is then processed into kibbles or similar dry pieces. Kibble is often formed using an extrusion process in which the mixture of dry and wet ingredients is subjected to mechanical work at a high pressure and temperature, then forced through small openings and cut off into kibble by a rotating knife. The wet kibble is then dried and optionally coated with one or more topical coatings which may include, for example, flavors, fats, oils, powders, and the like. Kibble also can be made from the dough using a baking process, rather than extrusion, wherein the dough is placed into a mold before dry-heat processing.
In another aspect, the present disclosure provides for a method for decreasing the weight in a companion animal, comprising feeding an effective amount of a composition as described herein. The companion animal may be a dog or cat.
In another aspect, the present disclosure provides for a method for decreasing the fat in a companion animal, comprising feeding an effective amount of a composition as described herein. The companion animal may be a dog or cat.
In certain embodiments, the lean mass of the companion animal is maintained while the fat is decreased. As such, in certain embodiments the present disclosure provides for a method for increasing the lean to fat ratio in a companion animal, comprising feeding an effective amount of a composition as described herein. The companion animal may be a dog or cat.
The examples and other implementations described herein are exemplary and not intended to be limiting in describing the full scope of compositions and methods of this disclosure. Equivalent changes, modifications and variations of specific implementations, materials, compositions and methods may be made within the scope of the present disclosure, with substantially similar results.
Eighteen healthy cats, considered to have no evidence of a chronic systemic disease, were fed either a control composition or test composition. The studies comprised two phases. The first phase included feeding the cat an amount of food to maintain body weight from a baseline time point to a post-intervention weight maintenance time point. In the second phase, the cats were fed a pet food composition in an amount to lose approximately 0.75-1% of total body weight from the post-intervention weight maintenance time point to a post-intervention weight loss time point. To accomplish this, body weight was measured during the pre-feed period and food offering was calculated as a percent of the observed maintenance energy requirement (that number of calories required for weight maintenance) in order to optimize weight loss through offering the amount of food that would result in the intended rate of loss. This was often about 90% of the calories required for maintenance. Specifically, the resting energy requirement (RER) was determined by the formula (70*kg ideal body weight0.75). Subsequently, the modulating activity factor was scaled from the original value that supported the obese condition (Activity Factor 1.2-1.8) to a value ˜90% lower. Each week the subject was reweighed and the activity factor scaled to increase (or decrease) the rate of weight loss if the rate was less (or more) than the target rate of 0.75-1% body weight per week. Details of the pet food compositions are summarized in Table 1 and Table 2.
As used herein, “Control” refers to a comparative example and “Test” refers to an exemplary composition of the present invention.
