Fats are found in the skin, bones, muscles, nerves, blood, and internal organs of pets. Most lipids are important components of cell membranes, and are also the raw materials for cell proliferation, renewal, and repair. At the same time, fats are also involved in the synthesis of certain metabolic regulatory substances in cells, such as sex hormones and bile acids. The proportion of fat in pet dogs' bodies is as high as 10-20% of their body weight. When the proportion of fat reaches a certain level, it will increase the palatability of cat food. In order to meet the fat content requirements of pet food, the amount of fat added usually reaches about 10% of the formula.

Pet feed fat-chicken fat

Chicken fat is a very common fat source in pet food, accounting for 10%-20% of total pet food production, and has a better flavor than other fats. Chicken fat comes from several different sources: refined, refined-refined, low-temperature blanched, etc. This makes the products vary in quality, consistency and cost, and also causes small differences in secondary nutrients (such as carotenoids), palatability and stability. Chicken fat contains fatty acids, proteins, fat-soluble vitamins, sterols and other components. Among them, fatty acid composition is one of the important indicators for evaluating the nutritional value of chicken fat, and it is also an important chemical component that affects its flavor.

Pet food fat-butter

Beef tallow is one of the earliest original fats used in pet food. Beef tallow is mostly saturated fatty acids (i.e. solid at higher temperatures), which also meets the definition of beef tallow, with a melting point of 40 degrees Celsius. For pets, saturated fats like beef tallow are negatively correlated with transport lipoproteins, which are prone to cholesterol and coronary heart disease. Pets are considered a "HDL species", which means that they have a good HDL advantage in circulation. About 50% of the fatty acids in beef tallow are saturated, with a small amount of linoleic acid and linolenic acid, and no long-chain fatty acids omega-3, which is similar to the saturation of mutton. Beef tallow has a higher digestibility than chicken fat and lard (a digestibility of more than 97%).

Different types of volatile substances can produce different flavor combinations, such as fat aroma, meat aroma, mushroom flavor, creamy flavor, etc. Specifically, cats prefer foods coated with beef tallow and chicken fat.

Pet food oil-fish oil

Fish oils are the most popular source of animal fats after beef, animal and poultry fats, and if pet food trends align with pet parents’ trends, fish oils may be seen as an increasingly popular ingredient for those concerned about their pet’s health in the coming years. In the process of considering oils and fats as healthy ingredients, more and more formulators are choosing oils and fats rich in omega 3 and omega 6 fatty acids. Fish oils are often seen as an important source of these key nutrients. Various fish oils have been highlighted in pet food for their functions, mainly for skin and coat health, as well as for their anti-inflammatory and heart-healthy effects.
