Description
Technical Field
The application relates to the field of pet food processing, in particular to a pet food capable of reducing tear marks of pets and a preparation method thereof.
Background
The pet food is specially provided for pets and small animals, is a high-grade pet food between human food and traditional livestock feed, has the advantages of comprehensive nutrition and good digestion and absorption, can supply the nutrition requirement for the pets, and can promote the growth of the pets and improve the immunity of the pets.
The tear marks of the pets are the tear marks which are brown or dark brown and remain for a long time due to the fact that excessive tear water of the pets wets hair to grow bacteria; under normal conditions, lacrimal glands secrete tears to moisten the eyes and then enter the nasal cavity through the lacrimal ducts, and the tears cannot flow out from the corners of the eyes, but when lacrimal glands secrete tears too much to be discharged from the nasal ducts, the tears can flow out from the corners of the eyes.
The reason for forming tear marks is many, if the pet is not careful in normal diet, people often eat food, excessive salt or too greasy diet is ingested, so that the excessive salt and grease in the pet body are easy to cause the tear marks to be secreted and exuberant, and meanwhile, harmful bacteria in intestinal tracts can be fermented abnormally, so that the tear marks are generated by the pet; if the lacrimal gland of the pet is developed and discharges too much tears in a short time or the nasolacrimal duct is blocked, tears cannot be discharged from the lacrimal duct, tears only flow out from the canthus, and tear marks are formed at the places where tears flow over time; in addition, when the pets are infected with ocular inflammation or excessive internal heat, red and swollen eyes and increased secretion of eyes are easily caused, and tear marks are generated.
Under the general circumstances, after the tear marks appear on the pet, the owner generally eats special eye drops or cleaning agents for the pet to clean, but the special cleaning agents for the tear marks disclosed in the prior art are less, and the common cleaning agents have poor tear mark removing capability and strong irritation and are not suitable for sensitive positions of eyes, or can only temporarily clean the tear marks, so that the generation of the tear marks of the pet cannot be fundamentally reduced.
Therefore, how to prepare a pet food capable of reducing the tear marks of pets, which not only can reduce the generation of the tear marks of the pets, but also has better tear mark removing effect is a problem to be solved.
