Description

Cat food for improving growth and digestion functions and preparation method thereof

Technical Field

The invention relates to the technical field of pet food, in particular to cat food for improving growth and digestion functions and a preparation method thereof.

Background

Different problems exist in the actual preparation process of the cat feed, namely, the simple transplantation of the mannase, the pectinase and the xylosidase from the livestock feed to the cat feed is not feasible, and the adaptive formula problem is solved in the actual production. The cat food mainly uses grain raw materials to provide energy, but the grain raw materials contain a plurality of anti-nutrient substances and cannot be absorbed by animal bodies.

Disclosure of Invention

Aiming at the technical defects, the invention provides the cat food for improving the growth and digestion functions and the preparation method thereof.

In order to solve the technical problems, the technical scheme adopted by the invention is as follows: the cat food comprises the following components: xylanase, mannase, pectinase, and daily ration; fully mixing xylosidase, mannase, pectinase and daily ration, wherein the weight parts are respectively as follows: 0.01-0.1 part of xylosidase, 0.01-0.1 part of mannase and 0.01-0.1 part of pectinase; the daily ration is as follows: corn, bean pulp, hawthorn, rapeseed pulp and olive oil; the daily ration comprises the following components in parts by weight: 30-50 parts of corn, 15-25 parts of soybean meal, 5-15 parts of hawthorn, 3-7 parts of rapeseed meal and 2-5 parts of olive oil; the enzyme activity unit of the xylanase is not less than 12000U/g, the enzyme activity unit of the mannase is not less than 3000U/g, and the enzyme activity unit of the pectinase is not less than 1500U/g; the daily ration comprises the following preparation steps:

crushing raw materials: taking the corn, the soybean meal, the hawthorn, the rapeseed meal and the olive oil in sequence according to parts by weight, and then adding the mixture into a pulverizer for pulverization;

uniformly mixing raw materials: pouring the crushed raw materials into a stirrer for stirring uniformly;

puffing: pouring the uniformly stirred raw materials into a double-screw extruder for puffing processing;

drying: and (3) drying the puffed raw materials at high temperature, and then fully mixing the puffed raw materials with chicken fat to obtain a semi-finished product.

Further optimizing the technical scheme, the steps are as follows:

s1, taking the xylosidase, the mannase and the pectinase in sequence according to parts by weight, and then preparing serous fluid;

and S2, uniformly coating the slurry and the semi-finished product, and performing low-temperature cooling to obtain the finished product grain.

Compared with the prior art, the invention has the following advantages: by adding the xylosidase, the mannase and the pectinase preparation, the anti-nutrient substance and the gastrointestinal function of the grains are improved, so that the utilization of the nutrients of the feed for cats is improved, and the good growth of the cats is promoted.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

Firstly, blending the daily ration, wherein the daily ration comprises the following steps: 35 parts of corn, 23 parts of soybean meal, 11 parts of hawthorn, 5 parts of rapeseed meal and 4 parts of olive oil, and then on the basis, xylosidase, mannase and pectinase in different parts are sequentially added for experiment.

Example 2	0.05 part	-	-	3
					Example 3	0.08 portion of	-	-	3
Example 4	0.05 part	0.03 part	-	4

					Example 9	0.05 part	0.06 part	0.08 portion of	7
Example 10	-	-	-	1

In the combination of examples 1-9, the daily weight gain of pet cats increased rapidly with the addition of xylanase, mannan, and pectinase, but the absorption-promoting activity of xylanase, mannanase, and pectinase was found to have a certain threshold value with the continuous addition of xylanase, mannanase, and pectinase.

In summary, the best embodiment of the present application is the embodiment 8, and the best embodiment 8 of the present application and the commercially available cat food are used to perform the feeding test on the pet cat, and the test results are shown in the following table
