Milk composition for companion animals {MILK COMPOSITION FOR COMPANION ANIMALS}

The present invention relates to a milk composition for companion animals, and more particularly, to a milk composition for companion animals in which nutritional components such as fat, protein, and inorganic salts are balanced and the lactose content is low.

Feed for companion animals is intended to supply the calories and nutrients necessary for the activities of companion animals, and milk containing essential nutrients such as high-quality protein, calcium and riboflavin is mainly distributed. Milk contains lactose as a carbohydrate. When milk is ingested, lactose is broken down into glucose and galactose by lactase located in the mucous membrane of the small intestine, which is then digested and absorbed. However, in the case of companion animals such as dogs and cats, lactose-degrading enzymes are not present in their body, so if they consume human milk, diarrhea, allergies, pancreatitis, etc. may appear Therefore, milk supplied as pet food must be reduced in lactose or lactose removed.

In this regard, Korean Patent Registration No. 10-0522273 discloses a powder based on milk for pets. However, when the content of lactose is reduced using powdered milk, not only lactose but also the content of essential nutrients such as protein, fat, and inorganic salts may be reduced together, and the flavor of milk will be reduced, which will decrease the preference of companion animals. can
