The application of probiotics in pet feeding

Learn about probiotics

Probiotics are a general term for a class of active microorganisms that colonize the intestines and reproductive systems of animals and can produce definite health effects. At present, probiotics widely used in pet field include Lactobacillus, Bifidobacterium and Enterococcus. Using probiotics in moderation is good for your pet’s gastrointestinal health and may even boost your pet’s own immunity.

The main mechanisms of action of probiotics include enhancing the intestinal epithelial barrier, adhering to the intestinal mucosa to inhibit pathogen adhesion, competitively eliminating pathogenic microorganisms, producing antimicrobial substances, and regulating the immune system. Because probiotics are widely used in the pet market, on the one hand, they are added to food and health products to prevent gastrointestinal discomfort and allergies that may occur in pets, and on the other hand, they are added to sprays, deodorants or pets. In hair care, it has a wide range of applications and has certain prospects.

Wide application of probiotics in pet market

There are many clinical applications of probiotics, and some scholars have selected several pet dogs for testing. 0.25 g of propionic acid, 0.25 g of butyric acid, 0.25 g of p-cresol and 0.25 g of indole were selected, and chloroform and acetone were added and mixed at 1:1 to form a constant volume reagent. The test was carried out in the same environment, and the feeding and management were the same. After feeding for a period of time, observe the feces of pet dogs every day, including state, color, smell, etc., and detect the content of propionic acid, butyric acid, p-cresol and indole in feces of dogs after supplementing with probiotics. The results showed that the contents of indole and other putrefactive substances decreased, while the contents of propionic acid, butyric acid and p-cresol increased.

Therefore, it is speculated that the dog food added with probiotics acts on the surface of the intestinal mucosa through the intestinal cell wall phosphochoic acid and mucosal epithelial cells, reducing the pH in the intestinal tract, forming an acidic environment, effectively inhibiting the invasion of pathogenic bacteria into the body, and indirectly improving the At the same time, it can also greatly reduce the synthesis of metabolites of spoilage bacteria in the body.

Some scholars have shown through many experiments that the preparation prepared with Bacillus, Lactobacillus and Yeast can promote the growth of young pets; after feeding Lactobacillus to pet dogs, the number of E. The digestibility of pet dogs is improved, which indicates that Lactobacillus has the effect of promoting digestion and absorption; the zymosan in the yeast cell wall has the effect of increasing the phagocytic activity of phagocytes and can improve the immunity of the body. Therefore, the use of probiotics in specific environments can enhance the Pet resistance, reduce the occurrence of diseases; the micro-ecological preparation made of Lactobacillus acidophilus Lactobacillus casei and Enterococcus faecium with a concentration of 5×108 Cfun has a good healing effect on pet diarrhea, and can be used in the late recovery period of acute intestinal diseases The effect of probiotics is obvious; at the same time, after feeding probiotics, the content of acetic acid, propionic acid and butyric acid in pet feces increases, the content of spoilage decreases, and the production of harmful gases is reduced, thereby reducing environmental pollution.

1. Prevention and treatment of gastrointestinal diseases in pets

Diarrhea is one of the common diseases in pets’ daily life. There are many reasons for diarrhea, such as unclean drinking water, indigestion, abuse of antibiotics, etc., which will cause the imbalance of pet’s intestinal flora and eventually lead to diarrhea. Adding an appropriate dose of probiotics to pet food can effectively improve the pet’s intestinal flora environment, thereby preventing diarrhea.

When pets have obvious diarrhea, the purpose of treating pet diarrhea can also be achieved by directly consuming an appropriate amount of probiotics. Studies have found that Brady’s probiotics are effective in treating and preventing diarrhea in pets. At present, Escherichia coli is one of the main causes of diarrhea in pets. Escherichia coli will first infect the damaged intestine, then destroy the intestinal barrier, and then connect with specific proteins, which will eventually cause gastrointestinal discomfort in animals and cause diarrhea. Brady’s probiotics can effectively reverse the specific proteins of tight junctions after eating, and can also delay the death rate of epithelial cells, effectively reducing the number of E. coli in pets. In addition, for pet dogs, Bifidobacterium and Bacillus can significantly inhibit the diarrhea of ​​pet dogs and effectively improve the intestinal flora environment of pet dogs.

2. Improve pet’s growth performance and immune function

The immune system of pets is still relatively fragile when they are just born. At this time, pets are very vulnerable to external influences, and it is easy to cause stress reactions or other diseases that are not conducive to pet health due to changing the environment or improper feeding, which in turn affects pets. own development and growth.

Probiotic supplementation can promote gastrointestinal motility and improve gastrointestinal disorders, and probiotics can synthesize digestive enzymes in the gastrointestinal tract, and then synthesize a large amount of vitamins, amino acids and other nutrients in pets, and can also promote pets. Absorb and promote healthy growth of pets. In this process, probiotics also participate in the growth and development of pet immune organs. As an important part of pet immune system, the gut can induce intestinal epithelial cells to produce cytokines and induce M cell-mediated gut-associated lymphoid tissue immunity. Response, thereby regulating the adaptive immune response in the gut, and enhancing the pet’s immunity. After surgery, you can also help your pet recover by consuming an appropriate amount of probiotics.

3. Prevent pet obesity

In recent years, the obesity rate of pets has increased significantly, mainly due to the large amount of carbohydrates and fats in the food that pets eat daily. Pet obesity is generally judged by weight. Overweight pets are very likely to cause major diseases such as cardiovascular disease and diabetes, which will also have a greater negative impact on the pet’s bones, and ultimately pose a serious threat to the pet’s life.

Akk is a common bacterium that exists in animal intestines and is involved in the regulation of host obesity. Taking Akk bacteria can significantly reduce the level of peptide secretion in vivo toxins and inflammation in the intestine, and enhance the intestinal barrier and intestinal peptide secretion. This probiotic is used to improve pet obesity. application provides a factual basis. Foods with high fat content will directly have a greater negative impact on the pet’s intestinal environment. Appropriate supplementation of probiotics can relieve intestinal inflammation, regulate blood lipids and cholesterol in pets, and effectively improve pet obesity. However, at present, probiotics have no obvious effect on obesity caused by age. Therefore, further research is needed on the regulation of probiotics on pet obesity.

4. Beneficial for pet oral health

Oral disease is one of the common diseases of pets, such as the common oral inflammation in cats. When it is too serious, it needs to be treated by full mouth extraction, which seriously affects the cat’s health and increases the cat’s pain.

Probiotics can directly help microorganisms and proteins to effectively combine to form biofilms or directly interfere with the attachment of bacteria to pets’ mouths, so as to prevent oral problems. Probiotics can synthesize inhibitory substances such as hydrogen peroxide and bacteriocin, which can inhibit the reproduction of bacteria and ensure the oral health of pets. A large number of studies have proved that the antibacterial activity has stronger activity in a strong acid environment, and it has been confirmed that probiotics can have an antibacterial effect by releasing hydrogen peroxide and inhibiting the growth of pathogenic bacteria, and hydrogen peroxide will not produce or produce a small amount of decomposition. The microorganisms of hydrogen oxide enzymes have a toxic effect and are beneficial to the oral health of pets.

The application prospect of probiotics in the pet market

In recent years, pet-specific probiotics or human-pet-shared probiotics have made great progress. The current pet probiotics market in my country is still dominated by capsules, tablets or directly adding probiotics to pet food. Some companies have added probiotics to pet toys and pet treats, such as mixing probiotics. Chlorophyll, mint, etc. are made into pet-specific biscuits, which have a certain effect on pet oral cleaning and maintaining oral health. In other words, adding probiotics to pets’ daily food or snacks can ensure the intake of pets’ probiotics, thereby regulating the pet’s gastrointestinal flora environment and improving the pet’s gastrointestinal health.

In addition, probiotics also have obvious effects on preventing pet intestinal diseases and obesity. However, the application of probiotics in my country is still mainly in health products and food, and there is a lack of development in the treatment of pet diseases. Therefore, in the future, research and development can focus on the improvement and treatment of pet health by probiotics, and in-depth study of the therapeutic effect of probiotics on pet diseases, so as to promote the further development and application of probiotics in the pet market.


With economic development and the continuous improvement of people’s living standards, the status of pets in people’s hearts has been significantly improved, and pets have become more “family members” who accompany their owners in their lives, giving their owners spiritual and emotional sustenance. Therefore, Pet health has become an issue of great concern to owners.

Pets will inevitably encounter various problems in the process of raising pets, illness is inevitable, antibiotics will inevitably be used in the treatment process, and the abuse of antibiotics will have a greater negative impact on pet health, so an alternative to antibiotics is urgently needed. , and probiotics are a good choice. Apply probiotics to pet food, health products and daily necessities, actively adjust the pet’s intestinal flora environment in daily life, improve pet oral problems, control pet obesity problems, and improve pet immunity, so as to protect pet health.

Therefore, in the pet market, we should pay attention to the research and development of probiotics products, actively promote the further development of probiotics in the pet medical industry, and deeply explore the effect of probiotics on pets to prevent, alleviate and treat pet diseases.
