Description

FIELD OF THE INVENTION The present invention relates to a process for the production of complete cat food suitable for general use from slaughterhouse by-products, vegetable and animal protein flours, and mineral supplements. It is known that there is a growing worldwide demand for dog and cat food. It is a basic requirement for dog and cat food that the consumer needs the animal. Because carnivorous animals, such as dogs and cats, are relatively short in their digestive tract system, they require concentrated nutrients. Food should not be fatty, carbohydrate-rich, because animals will gain weight. Satisfaction also requires 3-6% ballast. Foods must contain essential amino acids, vitamins, because the carnivores are unable to synthesize these substances.

The so-called so-called "nourishments" that meet all the animal's food requirements. several formulations are known for producing complete nutrition. Some wanted synthetic supplements to achieve the full nutritional value of the diet. This includes most dog-cat foods, such as: FULL-DOG DOG FOOD,

HUNDIN, PROTECAN, LATICAN, KUKE DELICT, ALTROMIN, ETC. Other formulations are believed to achieve the nutritional value by choosing their ingredients. Such is MARD EL, HAMM DOG FOOD. There is an additional need for cat and dog food to meet the requirements of an animal of varying maturity, body weight, age, health and environmental conditions, i.e., general cat food. Known dog foods only partially meet this requirement, such as HUNDIN dog food for puppies and lactating dogs, or LATICAN dog food primarily for experimental purposes. An important demand for food is the digestibility of food due to the short digestive tract system of carnivorous animals. Therefore, most regulations, such as the US NRC standard, require 80% digestibility of dog food. The digestibility of most dog and cat food is less than 70-80%.

Experience has shown that predators (including dogs) prefer to eat dog meat. Based on this observation, the German Patent Application No. 2915351, which describes a supplementary method for dog food containing gastrointestinal tract. The dog food produced by the process is not complete but merely complementary feed. The product is preserved with fat and placed in a tube.

The cost-effectiveness of the formulations is affected by the manufacturing process used. The manufacturing process for dog food with a moisture content of 50-80% is canned, heat-treated canned food. Shelf life is unlimited and can be used within a short period of time. This includes U.S. Patent No. 1371558, which produces a semi-moist (40-50% moisture) formulation. They also add chemical preservatives to enhance shelf life.

The manufacturing process for formulations with a moisture content below 10% is drying, granulation. The dried, granular formulation can be stored for a long period of time, is well-administered and does not reduce its nutritional value during storage. Most dog and cat food production processes are based on drying. Formulations of a specific manufacturing process include those which use a technological process other than the normal (cooking, drying) process. For example, the production process of HUNDIN or the FULL VALUE DOG DOGS includes the exploration of plant carbohydrates. And the HAMM DOG food is made by extrusion. English Patent No. 2095970 generates animal food compositions by selecting the type and proportion of raw materials using conventional manufacturing technology (drying or heat treatment). He believes that the nutritional value of dog food is achieved by changing the proportion of different ingredients.

None of these formulations fully meet the needs listed. The processes known so far from the process of the present invention differ in that they use synthetic auxiliary materials, or involve the digestion of plant carbohydrates, or employ a special manufacturing process - extrusion, canning - which increases the cost of production. At the beginning of our research work, we set ourselves the goal of developing a process for the production of generally usable, complete cat food with at least 85% digestibility, fast nutrient intake from domestic raw materials (waste, by-products).

The essence of the process according to the invention is to prepare cat food from the contents of a slaughterhouse cattle ranch, cattle blood, animal protein flour, cereal meal and mineral supplements by pre-drying the ranching content at 30-50 ° C, preferably at 37 'C. It is pre-partitioned with a natural enzyme for 1 hour, preferably 4 hours, dried at 100-130 ° C to a maximum moisture content of 10%, 20-50% of dried, coagulated bovine blood, 20-50% of mixed animal protein flour , 10-50% of corncrumbs and 0.5-8.0% of your mineral supplement are mixed and minced. Further, the components of the composition are selected to meet the requirement for complete nutrients. By choosing the proportions of the components, you can make general-purpose dog-cat food. Only natural materials provide the nutritional needs of dogs and cats. (See Tables 1 and 2)

Some exemplary embodiments of the process of the present invention are illustrated by the following examples:

Example 1

The contents of 1,000 kg of slaughterhouse cattle are placed in a roller blender and kept at 37 ° C for 4-6 hours. The material was then sterilized at 130 ° C for 30 minutes and then air-dried. 800 kg of cow's blood is coagulated by heat in a manner known per se, the plasma portion is thawed and the coagulum is dried in vacuo. The beef and beef meal is mixed and 350 kg of mixed animal protein flour, 250 kg of corn meal, 25 kg of bone meal and 25 kg of dicalcium phosphate are added. The mixture is homogenized and minced.

Example 2

Example 1 except that collagen is used as a granulating aid and the mixture is granulated.

Example 3

The procedure of Example 1 is followed except that defatted cooked bone and / or ATEFOKA is used to adjust the calcium and phosphorus content.

Example 4

The procedure of Example 1 was followed, except that a cooked pen, flour, detergent and / or enzyme-digested with detergent and / or enzyme was used to adjust the crude protein level.

The main advantages of the process according to the invention can be summarized in the fact that dried cat-cat food is prepared using domestic source raw materials and by-products at low production costs. So far, we produce valuable feed from the ration of horseradish which has been classified as hul20 crates. The basic co-protein is digested, resulting in a minimum digestibility of 85%. The composition of the preparation and the choice of its components makes the cat-cat food worth at least 25 JeB and ensures that the animals' food intake is not reduced during long-term feeding. The amount of ballast in the preparation gives the animals a feeling of satiety, and does not cause intestinal catarrh or intestinal weakness. The method of the present invention and the choice of its components make it possible to prepare cat food of general use.
