Crude fat

Raw fat is the fat contained in the feed. This fat comes from the individual feedstuffs contained in the feed, e.g. from the grain. In particularly high-energy feeds, pure vegetable fat or oil is also used. Besides carbohydrates, fat is the most important source of energyin the diet. In terms of quantity, it is behind carbohydrates and proteins in all common feeds, but it is characterised by an energy content that is two to three times higher, so that even small changes in the fat content have a significant influence on the energy content of a feed. In purely chemical terms, fat consists of glycerol esters of fatty acids. Some of these fatty acids are essential, i.e. vital, nutritional factors for the animal. These are the polyunsaturated fatty acids linoleic, linolenic and arachidonic acid. At least the linoleic acid must be supplied to the animal in a certain quantity daily with the food. The other two essential fatty acids mentioned can then be formed by the body itself from the linoleic acid. Dietary fat is also important for the health and performance of the body as a carrier of the so-called fat-soluble vitamins. Soybeans, rapeseed and sunflower seeds are particularly rich in fat. In comparison, cereals contain little fat.
