Feed crushing particle size: 1. The pulverized particle size of corn and soybean meal in suckling pig material is 1.2-1.5Φ(mm) 2, the crushed size of corn and soybean meal in pig flower material is 1.5Φ (mm) 3, the crushing size of corn and soybean meal in the piglet is 1.5Φ (mm) 4. The pulverized particle size of corn and soybean meal in the middle pig material is 2.0Φ(mm) 5. The crushing size of corn and soybean meal in large pig feed is 2.0Φ(mm) 6, the size of corn and soybean meal in the lactating sow feed is 2.0Φ (mm) 7. The pulverized size of corn and soybean meal in pregnant sows is 2.0Φ(mm) The most commonly used probiotics at present are Lactobacillus, Bacillus subtilis, Bifidobacterium, and Streptococcus, which are resident microorganisms of the gastrointestinal tract of animals. The normal physiological index of pigs Body temperature: 38-39.5 °C Breathing: 10-20-40 times (small pig) / minute Pulse: 60-80 beats / min In the case of heat stress, the feed intake of the animal will decrease. In order to prevent the decline of production performance, fat with high energy content can be added to increase the energy concentration to ensure that sufficient energy can be taken in the case of a decrease in feed intake. When animals are under heat stress, lowering protein levels can alleviate the effects of heat stress on animal performance. Stress increases the secretion of adrenaline and norepinephrine in the animal, causing accelerated glycogen and fat breakdown, and an increase in blood glucose concentration, thereby reducing feed intake. In China, protein feed is seriously insufficient, and some feed protein quality is also poor. It is advisable to use a digestible amino acid system as early as possible. In the production practice, when adding synthetic amino acids (lysine, methionine), the crude protein level can be reduced by 2-3%. Supplementing the first and second limiting amino acids is the most effective way to increase feed protein and amino acid utilization. At present, synthetic amino acids that can be used in production are dependent on four amino acids, such as egg, color and sulphate, but the cost of addition of threonine and tryptophan is also high, and it is generally used less in production. In some countries, the nutritional needs or feeding standards list only the most susceptible lysine, methionine (cysteine), tryptophan, threonine, isoleucine and arginine in the diet ( The amount of poultry needed). When heat stress, the feed intake of animals decreases, and if the protein level of the diet is increased, the heat increase will increase and heat stress will be aggravated. Therefore, it is necessary to balance the amino acid of the diet and prepare the diet according to the digestible amino acid to reduce the crude protein level, and ensure that the amino acid intake is sufficient, and the animal performance will not decrease. Properly increasing dietary calcium can increase the heat resistance of animals. The addition of sodium bicarbonate can alleviate the adverse effects of heat stress. During heat stress, the amount of vitamin C synthesized in the animal can not meet the needs, and the addition of vitamin C to the diet can reduce heat stress. Adding 20-50 mg of vitamin C per kilogram of feed in the feed can effectively resist stress and reduce the chance of disease in the herd to ensure its healthy growth. The drug administration effect is different depending on the route of administration. In general, systemic infection is preferably administered by injection, intestinal infection is preferably administered orally, respiratory infection is preferably administered by drinking water, and skin infection is preferably administered by smearing. Pigs are administered intramuscularly as well, and drinking water is better than administration of the mixture. The use of calcium iodate as the source of iodine reduces the redox reaction. Do not mix any two or more additives without diluent isolation. Medical stone is a compound mineral or medicinal rock that is non-toxic, harmless and biologically active. The main chemical component of medical stone is inorganic aluminosilicate. These include Sl2O3, Fe2O3, FeO, MgO, CaO, k2O, Na2O, TiO2, p2O5, MnO, etc., and also contain all the essential elements required by animals, such as K, Na, Ca, Mg, Cu, Mo and other trace elements. There are about 58 kinds of rare earth elements.
2-Cyanoguanidine is produced by treating cyanamide with base. It is produced in soil by decomposition of cyanamide. A variety of useful compounds are produced from 2-cyanoguanidine, guanidines and melamine.Use as a decolorant in sewage treatment.
