First, the concept of grain The aging food generally refers to storage for more than three years, and the storage quality is obviously reduced. It is not suitable for direct use as food for oral food. The main indicators for the aging of food are: fatty acid value, viscosity, tasting score and color odor. Among them, one of the three indicators of fatty acid value, viscosity and tasting score reaches the “Chenhua†requirement, which is recognized as “Chenâ€. Food." According to the state regulations, Chenhua Grain can only be sold to specific feed processing and brewing enterprises through auction. 　 Second, the potential harm of grain 　 1, the nutritional value is reduced As a biologically active organism, food contains macromolecules such as water, lipids, proteins and sugars. During storage, a series of dynamic changes inevitably occur due to the external environment, which means that the grain color becomes dark and germinated. The rate is reduced and the viability is reduced. This is the process of food aging. In this process, lipids change the fastest, starch is second, and protein is the slowest. Lipids decompose during the long-term survival of food to produce free fatty acids, which are oxidized to produce aldehydes (such as hexanal), ketones (such as methyl ethyl ketone, pentanone, octanone), acids and hydrocarbons, which can damage The liver of an animal. Consumption of hen-derived grain-converted feed will result in reduced feed intake, increased feed-to-meat ratio, and prolonged slaughtering time. The harmful substances produced by lipid peroxidation will also change the structure of the protein, lose the nutrition of the protein, reduce the absorption of the fat-soluble vitamins, and cause the inflammatory reaction of the adipose tissue to cause the fat to turn yellow to form "yellow meat". 　 2, mycotoxins exceed the standard Excessive toxins are the most direct cause of aging food. The aging of the Phytophthora toxin is complex and has a wide variety of toxins, including aflatoxin, vomiting toxin, zearalenone, ochratoxin and fumagillin. Feeding mycotoxin-contaminated foods can reduce animal performance, mainly in terms of daily gain, reduced feed intake, and reduced feed utilization (as shown in the table). Effect of Feed on Animal Production Performance When the mycotoxin is severe, it will cause pathological damage to the liver of the livestock. The liver is the main target organ of aflatoxin action, which can cause liver tissue enlargement, steatosis, bile duct hyperplasia, hepatocyte vacuolation and necrosis. In livestock and poultry, ducks are more sensitive to mycotoxins than chickens. In the case of serious contamination of raw materials, it is easy to cause liver damage and cause diseases such as "flower liver". Mycotoxins accumulate in the liver, causing chronic poisoning in animals, which seriously affects the performance and health of livestock and poultry. Third, grain use strategy When aging food is used as feed, it is generally adjusted according to its fatty acid value (when the fatty acid value of aged food reaches 100mg KOH/100g, it cannot be used for feed ingredients). For example, most of the fatty acids used in Shandong are 37-50mg KOH/100g, which can be used completely, but it should be used with bile acid. The recommended dosage is 0.15-0.2 kg. Add bile acids, one is to protect the liver, help the body to discharge toxins, avoid chronic poisoning of livestock and poultry; the second is to promote fat digestion, promote the absorption and utilization of fat-soluble vitamins, improve the digestion and utilization of feed, and enable livestock and poultry to achieve the effect of using normal corn; Third, bile acids can also help remove free radicals from the oxidation of fat in feeds and prevent the use of "yellow meat" caused by aged grains. The montmorillonite is added to the raw material, which is mainly for aflatoxin, and has relatively poor adsorption effect on zearalenone and vomiting toxin, and is easily affected by environmental acidity, desorption phenomenon, and adsorption of nutrients in the feed. Substances, the destruction of feed nutrient balance and other issues often do not achieve the desired results. Bile acid itself is secreted by the liver, which can help the liver to effectively decompose the toxins in the body and in the body, protect the liver, and keep the animals away from hepatobiliary diseases.
