Description

Technical Field

[0001] The invention relates to the technical field of pet food, in particular to a complete freeze-dried raw bone and meat pet functional food and a preparation method thereof. Background Art

[0002] As people's living standards continue to improve, more and more people are keeping pets. The status of pets in people's hearts has been significantly improved. They have become important members of many families. They can give people spiritual and emotional sustenance, add color to life, and also help people relieve the stress of life; therefore, the health of pets has naturally become a matter of great concern to people.

[0003] Pet food is a high-end animal food that is processed and made specifically for pets to eat. It is between human food and traditional livestock and poultry feed, and can provide basic nutrients for the growth, development, and health of pets. As people pay more and more attention to pet health, higher expectations are placed on the impact of pet food on pet health.

[0004] There is an optimal physiological state of mutual dependence and mutual restraint between pets and the microorganisms living in their bodies. The two sides maintain the flow of matter, energy and information. Therefore, the microorganisms carried by the pet's body are closely related to the pet's own physiology, nutrition, digestion, absorption, immunity and biological antagonism. There are a large number of different types of microorganisms living in the gastrointestinal tract of healthy pets. These microorganisms are called intestinal flora, which can inhibit the growth of pathogens, activate the gastrointestinal immune system, prevent diarrhea and constipation, and regulate blood lipids. When pets are improperly fed, malnourished or old and weak, the intestinal flora will be imbalanced, resulting in digestion and absorption disorders, poor appetite, abdominal distension, constipation and other discomfort reactions. The main symptoms are diarrhea, vomiting, frequent and watery stools, malnutrition, dehydration, weight loss, etc.

[0005] The traditional method of preventing or treating pet diarrhea and vomiting is to use antibiotics. Although it has significant therapeutic effects, it may have adverse effects on the pet's digestive system, such as destroying the beneficial intestinal flora, producing drug resistance, indigestion or other intestinal problems; therefore, if probiotics and other substances that have gastrointestinal function are added exogenously to pet food, it will improve the pet's intestinal microenvironment and regulate the balance of flora, which is of great significance for the use of non-antibiotic drugs to prevent or treat pet diarrhea. Summary of the invention

[0006] The purpose of the present invention is to provide a complete freeze-dried raw bone and meat functional food for pets and a preparation method thereof. The complete freeze-dried raw bone and meat functional food for pets has probiotics and other substances with gastrointestinal function adjusted added to the freeze-dried raw bone and meat, which effectively improves the intestinal microenvironment of the pet and regulates the balance of the flora, and is of great significance for preventing or treating pet diarrhea.
