Technical Field

The invention relates to a pet food component, in particular to a pet food component capable of effectively reducing the oral odor of pets, and belongs to the field of food processing.

Background

With the pet-raising users attaching more and more importance to pets, the pet's dietary habits are gradually changing. The oral cavity problems of pets bring troubles to pet holders, and the existing pet food formula components cannot effectively solve the problem of oral cavity peculiar smell of pets. The problems caused by the oral cavity abnormality of the pet have affected the health of the pet and the pet-raising experience of pet feeders. CN 107691780A discloses a preparation method of a dog feed, which provides a feed capable of preventing and relieving dog halitosis, but the application range is limited to dogs, the feed contains too much starch and too little meat protein, and the requirement of pet pets on relieving cat halitosis cannot be met.
