Problems solved by technology

Although antibiotics are fast and efficient in the treatment of pet diarrhea, long-term large-scale use will cause antibiotic residue pollution and the production of "super-resistant bacteria", which will break the homeostasis of pets and cause endogenous infections in pets
In recent years, some new pet preparations have emerged, but their common characteristics are high price and complicated administration routes, which make the cost of pet owners too high, and the cost of breeding has increased sharply, so the promotion of new preparations is difficult

Embodiment 1

[0037] Please refer to figure 1 , the preparation method of antimicrobial peptide type pet feed of the present invention, technological process comprises:

[0038] Bacillus subtilis fermentation treatment, pet basic feed preparation treatment, pet basic feed drying treatment, first cooling treatment, spraying oil treatment, spraying fermentation liquid treatment, second cooling treatment, packaging treatment, to produce antimicrobial peptide type pet food. In Example 1, the puffing temperature during the preparation of pet feed granules was 120 degrees Celsius, and the temperature of the puffed feed granules was cooled to 50 degrees Celsius in the first cooling treatment. Add 0.09 kg of vegetable oil to the feed for spraying, and add 0.4 liter of fermented liquid to 1 kg of basic feed for spraying in the fermentation broth spraying process. The water content of the antimicrobial peptide type pet feed is lower than 14%. The number of Bacillus subtilis used is BNCC179313, whi...

Embodiment 2

[0040] Please refer to figure 1 , the preparation method of antimicrobial peptide type pet feed of the present invention, technological process comprises:

[0041] Bacillus subtilis fermentation treatment, pet basic feed preparation treatment, pet basic feed drying treatment, first cooling treatment, spraying oil treatment, spraying fermentation liquid treatment, second cooling treatment, packaging treatment, to produce antimicrobial peptide type pet food. In Example 2, the puffing temperature during the preparation of pet feed granules was 135 degrees centigrade. In the first cooling treatment, the temperature of the puffed feed granules was cooled to 55 degrees centigrade. Add 0.1 kg of vegetable oil to the feed for spraying, and add 0.5 liter of fermented liquid to 1 kg of basic feed for spraying in the fermented liquid spraying treatment. The water content of the antimicrobial peptide type pet feed is lower than 14%.

Embodiment 3

[0043] Please refer to figure 1 , the preparation method of antimicrobial peptide type pet feed of the present invention, technological process comprises:

[0044]Bacillus subtilis fermentation treatment, pet basic feed preparation treatment, pet basic feed drying treatment, first cooling treatment, spraying oil treatment, spraying fermentation liquid treatment, second cooling treatment, packaging treatment, to produce antimicrobial peptide type pet food. In Example 3, the puffing temperature during the preparation of pet feed granules was 150 degrees Celsius, and the temperature of the puffed feed granules was cooled to 60 degrees Celsius in the first cooling treatment. The ratio of adding 0.11 kg of vegetable oil to the feed is sprayed, and the ratio of adding 0.6 liter of fermentation liquid to 1 kg of basic feed is sprayed in the fermentation liquid spraying treatment. The water content of the antimicrobial peptide type pet feed is lower than 14%.

Abstract

The invention discloses an antibacterial peptide type pet feed and a preparation method thereof. The method comprises the following steps of performing fermentation culture on screened high-yield antibacterial peptide strains; preparing a semi-finished basic pet feed, and performing puffing and granulating; uniformly spraying grease onto the surfaces of puffed particles of the basic pet feed; spraying a fermentation liquor onto the surfaces of the puffed particles of the basic pet feed which is subjected to grease spraying treatment to prepare the antibacterial peptide type pet feed. After the pet feed is puffed and granulated, the temperature is lowered, then an antibacterial peptide component is added, the structure and property of an antibacterial peptide are thus prevented from being damaged by high temperature, and the concentration of effective components in the feed is increased. According to the method, the antibacterial peptide is used as a pet feed raw material; since the antibacterial peptide has the advantages of great broad-spectrum bacterial and viral resistance, good immune regulation function and excellent growth promotion function, the life quality of pets is improved, and the probability of illness and death of the pets is lowered at the same time.

Description

technical field [0001] The invention relates to the technical field of pet feed preparation and processing, in particular to an antimicrobial peptide type pet feed and a preparation method thereof. Background technique [0002] With rising income levels and an aging society, Chinese demand for pets continues to grow. In China, which has a population of nearly 1.4 billion, there are about 90 million pet cats and dogs. According to reports, China is already the second largest pet market in the world after the United States, and the growing pet boom has given birth to the development of the pet economy industry chain. Among them, pet food, as a rigid demand for keeping pets, has the highest share in the pet industry, reaching 35.6. Against the background of the ever-increasing market size, pet owners are becoming more and more picky. When choosing pet food, they gradually put natural safety first. [0003] At present, the common pet feeds on the market contain various food a...
