Fats in animal feed are an essential ingredient providing energy and essential fatty acids that the animal's body cannot produce on its own. Different types of fats have different nutritional profiles and can have different effects on the health of the animal. Fats can be of animal or vegetable origin. Animal fats such as poultry, beef, chicken, salmon, fish and pork fat are rich in saturated fatty acids and can provide significant amounts of energy. Salmon and fish oil are particularly valued for their omega-3 fatty acid content. Vegetable fat is rich in unsaturated fatty acids and can help contribute to overall health and a shiny coat.
