The eared corn silage must first grind the forage, and the smashing can guarantee the compaction and can discharge the air; followed by compaction, the smaller pit side can be pressed with a small four-wheel tractor. There are small-scale farmers who can dig a simple pit, shovel clean, and put plastic sheeting to ensure air-free ventilation. The cellar can be filled with air by people to step on it. In the course of this production, add a little salt. In the process of making silage, salt is added to supplement Minerals and salt and increase its palatability. The amount of salt should generally be controlled to 0.5%, and no more than 0.6%, which is a ton of silage corn plus 5 kg to 6 kg of salt. Silage corn silage is not recommended to add urea. In some places, adding urea is mainly to provide some non-protein nitrogen in the feed. When ruminants are fed, such as cattle, sheep, and camels, there are a lot of microorganisms in the rumen of the animal. The microorganisms use the nitrogen-producing bacteria in urea. The body protein and the bacterial protein are absorbed and utilized by the animal as nutrients, and it may or may not be added when silage is done. Some farmers have the same reason to add urea when feeding ruminants. The theoretical data for moisture is 70% to 75%. In practice, grab a handful of silage and squeeze it hard. If the water droplets run down, the water is high. The silage with high moisture content will increase the temperature, which will affect the quality of silage. The best moisture content is 70% to 75%. Silage also has some precautions: First, the requirements for raw materials. For example, crops such as corn, it must be the first ear, grow into the best milk maturity; Second, in the production process, must be clean air, the ultimate goal is to create an anaerobic environment; Third, the entire After the pressure is over, it must be sealed and impervious to air to ensure the quality of silage. Minerals
The combination and collocation of mineral nutrient elements. Among these elements, in addition to carbon, oxygen, hydrogen, nitrogen and other elements mainly exist in the form of organic matter, the other 60 kinds of elements are collectively referred to as minerals, of which 25 kinds are necessary for human nutrition.Calcium, magnesium, potassium, sodium, phosphorus, sulfur, chlorine 7 kinds of element content is more, accounting for about 60% ~ 80% of the total minerals, so called macro elements, and iron, copper, iodine, zinc, manganese, molybdenum, cobalt, chromium, tin and vanadium, silicon, nickel, fluorine, etc. 14, because there are too few, within the body content less than 0. 005%, therefore is called the trace elements.
Synonyms Dietary essential minerals; Macro- and microminerals; Electrolytes; Trace elements Definition Mineral nutrients are inorganic substances that must be ingested and absorbed in adequate amounts to satisfy a wide variety of essential metabolic and/or structural functions in the body. Mineral nutrients are sometimes categorized according to the amount required in the human diet to maintain good nutrition. Macrominerals is a general term encompassing both bulk minerals (calcium, phosphorus, magnesium) and electrolytes (sodium, potassium, chloride), which are required to be ingested by humans in amounts of hundreds of milligrams to several grams per day. Microminerals or trace elements (including iron, zinc, copper, manganese, selenium , iodine, chromium, molybdenum) are required in amounts of a few milligrams or less per day. The latter members of this group, which are required only in amounts of micrograms per day, are sometimes referred to as ultratrace elements.
