First, all physiological processes of energy goose need energy to drive. The main sources of energy are carbohydrates and fats, which also decompose to produce heat energy in excess. Fat is a constituent of lipids in goose body tissues and also a carrier of fat-soluble vitamins. However, fat is a nutrient that can be replaced and can be converted from carbohydrates or proteins, and the added fat is more difficult to digest. Therefore, it is generally not necessary to add fat in feeds, and nutrient requirements may not be considered.
Protein protein constitutes an important component of the goose body and goose products. It is also one of the main raw materials for the formation of enzymes and hormones. It is related to the entire metabolism and cannot be replaced by other nutrients. It is necessary for life and production. nutrient.
Third, minerals and minerals play an important role in the life activities of the organism. According to the content of various minerals in animals, it is divided into constant elements and trace elements. For geese, in the case of adequate grazing or green fodder supply, in addition to calcium, phosphorus, chlorine, sodium to pay attention to appropriate supplements, other elements can generally meet the needs, do not have to supplement; in the feeding period, other elements should be appropriate supplement.
Vitamins Vitamins are substances that have a low level of feed and have a special role. Vitamins are important substances that ensure the normal operation of various physiological functions. Green feed is the main source of vitamins.
5. Moisture and moisture are important constituents of the goose body and are also the main factors that cannot be separated from all physiological activities. Water is a solvent that enters all substances in the goose body. It participates in the metabolism of substances and participates in the transport of nutrients or decomposition products. It can buffer the sudden changes in body fluids and help regulate body temperature.
