Animal fats and oils are lipids derived from animals: oils are liquid at room temperature, and fats are solid. Chemically, both fats and oils are composed of triglycerides. Although many animal parts and secretions may yield oil, in commercial practice, oil is extracted primarily from rendered tissue fats from livestock animals like pigs, chickens and cows. Dairy products yield animal fat and oil products such as butter.
Certain fats, such as goose fat, have a higher smoke point than other animal fats, but are still lower than many vegetable oils such as olive or avocado.
Animal fats are commonly consumed as part of a western diet in their semi-solid form as either milk, butter, lard, schmaltz, and dripping or more commonly as filler in factory produced meat, pet food and fast-food products.

Many animal fats and oils are consumed directly, or indirectly as ingredients in food. The oils serve a number of purposes in this role:
Secondly, oils can be heated, and used to cook foods. Oils suitable for this purpose must have a high flash point.
