Jinbao lets you understand the nutritional content of roughage
I. Classification of nutrients in feed
According to conventional analysis, the compounds constituting the plant and animal body are water, crude ash, crude protein (CP), crude fat or ethyl ether extract (EE), crude fiber (CF), and nitrogen-free extract (NFE).
1. Moisture
Moisture in animals and plants exists in two states. A type contained between the cells of plants and animals, which is not tightly bound to cells and is easily volatilized, known as free water or free water; and the other is closely associated with the intracellular colloidal substances to form a water film outside the colloid and is difficult to evaporate. Call it bound water or bound water. The sum of these two types of water that constitute the body and the animal is called total water.
2, rough ash
Residues resulting from burning at 550°C are mainly oxides, salts, and other minerals, and also include sediment mixed with feed, so they are referred to as crude ash or minerals.
3, crude protein
According to the Kjeldahl method, the total nitrogen in the feed is determined, and the product obtained by multiplying the total nitrogen value by 6.25 is called the crude protein in the feed. The nitrogen content of most proteins is quite similar, generally 14% to 19%, with an average of 16%. Therefore, when measuring protein, the content of protein can be calculated by measuring the nitrogen content in the sample.
Protein content = sample nitrogen content × 100/16 = sample nitrogen content × 6.25
In animals and plants, non-protein nitrogen is also present in addition to proteins. Therefore, the protein obtained from the nitrogen content measured as described above is usually referred to as crude protein.
4. Crude fat
Crude fats include components that are soluble in ether (fats, waxes, organic acids, ester-soluble pigments, fat-soluble vitamins, etc.) in feed, and therefore, crude fats are often referred to as ether extracts.
5. Carbonization artifacts
Carbohydrates are the main components of plant-based feed, accounting for about 50% to 80% of dry matter, and they are the main source of energy in animal diets. According to conventional analysis, carbohydrates can be divided into crude fiber and nitrogen-free extracts.
Crude fiber (CF) consists of cellulose, hemicellulose, polypentose, and inlaid substances (lignin, keratin), and is the main component of the plant cell wall. It is also the most difficult nutrient for digestion in feed.
In view of the above, in fact, roughage nutrition is still very high, of course, no matter what the pros and cons, so still need to strive for excellence.
