Biofermentation feed is a modern high-tech biotechnology product. It is made by adding certain energy feeds, protein feeds, vitamins, minerals, and trace elements, etc. after biofermentation with beneficial microbial straws. For raising pigs, not only good palatability, strong appetite, but also can enhance the body resistance to disease, improve feed conversion, reduce the cost of feeding, economical, is an integral part of the organic animal husbandry, it is worth promoting. First, the role of biological fermentation feed Functional biological fermentation feed containing more fiber-decomposing bacteria, semi-fiber decomposing bacteria, microbial enzymes useful microbial preparations in the animal body fermentation process can not only be difficult to digest the absorption of crude protein, The macromolecular substances in starch are processed and decomposed into small molecule nutrients such as glucose, amino acids and vitamins, which are easily digested and absorbed, and can greatly degrade crude fiber and produce a large amount of bioactive substances, thereby increasing the digestibility, absorption and nutritional value of feed. . In addition, the beneficial microorganisms in the biological fermentation feed can also kill pathogens, maintain the microecological balance in animals, enhance the immunity of functions, and have certain preventive and curative effects. Second, the production of bio-fermentation methods (a) bio-fermentation feed formula. 55% of reconstituted or grass powder, 16% of wheat bran, 15% of corn, 10% of cake, 2% of molasses or red peony, 2% of beneficial microorganism preparation (including cellulose decomposing bacteria, Bacillus, lactic acid bacteria, double There are dozens of strains of the five major bacterial groups including bacillus and yeast. (b) Production method of biological fermented feeds 1. The raw materials were weighed according to the above formula, crushed, sifted (1mm hole), and then mixed until ready. 2. There are two kinds of beneficial microorganism preparations: solid type and liquid type. If a solid type beneficial microorganism preparation is used, it can be directly added into the above raw materials and mixed evenly; if a liquid type beneficial microorganism preparation is used, it can be poured first. After tap water without bleaching powder or dissolved in deep water, brown sugar or molasses is added to make a uniform sugar-containing bacteria water. 3. The sugar-containing bacteria water or sugar water (referring to the use of solid beneficial microorganism preparations) is evenly sprayed in the fermentation material, mixed with sprinkled, so that the water content of the fermentation material reaches the level of hand-kneading, landing that is scattered, general materials, The weight ratio of water is about 1:0.4. 4. Put the fermented feed in a plastic bucket or a ceramic tank or a cement tank. After a little compaction, use a wooden stick with a diameter of 2 to 3 cm to punch the fermented feed and punch the hole to the bottom. The distance is 5 - 10cm. Then cover it with a board or a film and allow it to ferment naturally. When the general temperature is below 25°C, the fermentation time is 4 - 5 days, and when the temperature is above 25°C, it is 2 - 3 days. 5. After fermentation, the pH value is below 4--5 and there is a strong scent of wine, which means that the fermentation is successful. (C) The use of biological fermentation feeds 1. Biofermented feed compound formula reference formula (1) Piglet compound feed (%) Formula 1: Biological fermentation material 20, corn 52, soybean meal or bean cake 22, fish or compound egg powder 2, pig premix 4. Formula 2: Biological fermentation material 15, corn 44, bran 10, soybean meal or bean cake 24, fish meal or composite protein powder 3, pig premix 4. (2) Formulated feed for pigs (%) Formula 1: Biological fermentation material 25, corn 50, soybean meal or bean cake 21, pig premix 4 . Formulation 2: Biological Fermenting Material 30, Corn 38, Bran Grains 10, Soybean Meal or Bean Cake 24, Fish Meal or Composite Protein Powder 3, Pig Premix 4 . (3) Large pig compound feed (%) Formula 1: Biological fermentation material 30, corn 36, bran cereal 12, soybean meal or bean cake 16, pig premix 4. Formulation 2: Biological Fermenting Material 35, Corn 33, Gluten or Grain 12, Soybean Meal or Soybean Cake 16, Raw Pig Premix 4. 2. The use of biological fermentation materials. Use bio-fermented feeds to feed pigs without adding any other additives, without cooking, feeding directly after mixing with water (not suitable for holding water in hand), or feeding after mixing for several hours. good. When feeding, small pigs can have regular meals, medium and large pigs can freely feed indefinitely, feeding 2 to 3 times a day, each feeding amount to finish within 30 minutes, there is no material in the tank (80% full ) is appropriate. The biological fermentation material sold is a dry product, and the purchased product should be stored in a cool, dry and ventilated place after being purchased to avoid mold deterioration and causing pig poisoning. At the same time, attention should be paid to the prevention of rodent and insect pests. Third, to strengthen the pig breeding management 1. Pig farm selection and layout. Farms should be selected or built in areas without pollution, without “three wastes”, far away from residential areas, (city) urban areas and tourist areas, drainage, adequate water sources, good water quality, and convenient transportation. And living areas should be strictly separated. 2. Environmental hygiene in pig sheds. Pig farms (households) should pay attention to the construction of hardware facilities in the pig sheds, establish a strict health and epidemic prevention system, clean up the ditch in time, remove accumulated manure, weeds, eliminate mosquitoes and flies, regularly disinfect and deworm, and make the pig house winter Warm and cool in summer, the breeding density should not be too large. Generally, each pen house is reared with 8-10 heads, and 0.8--1.2 square meters per pig is appropriate. The ambient temperature of the pig house is 60kg below the weight of pigs. 16°C - 22°C (minimum 14°C), 60 - 90kg 14°C - 20°C (minimum 12°C), 90 - 100kg 12°C - 16°C (minimum 10°C) is preferred. Relative humidity of 45% - 75% is appropriate. 3. Reasonable grouping and careful training. Meat piglets should be grouped in accordance with the principles of sex, age, weight, physical fitness, and similar eating habits. It is best that piglets raised on the same lap come from the same nest in order to form a good colony order, and for newly purchased piglets It is necessary to carefully tune in order to develop five positions of eating, drinking, pulling, urine, and sleeping. 4. Prevent disease. For pigs, especially newly purchased piglets, left-imidazole hydrochloride or anthelmintic net insects are used, and gastric lavage is then fed with baking soda to enhance their gastrointestinal digestive capacity. Since 20 days of age, vaccination has been conducted for swine fever, swine plague, swine erysipelas, and paratyphoid vaccine for piglets. Piglets purchased on conditional farms are immunized in strict accordance with the degree of immunity provided by the farm. Found abnormal pigs, timely diagnosis and treatment to reduce losses. 5. Control drug residues. As the majority of pork hog pig farms (households), in the pig production and disease prevention and control, we must strictly implement the provisions of drug withdrawal, can not blindly use the state illegal drugs and random increase the dose; rational use of antibiotics, Do not add drugs or drug-containing additives to feeds themselves, and advocate the use of biosafety measures to prevent diseases. 6. Timely slaughter. The appropriate slaughter weight for the lean commercial pigs is 90--100kg. Premature slaughter, although high lean meat, but the slaughter rate is low, producing less meat, but also the fastest growing period of pigs, it is not economical; slaughter too late, fat increased, the proportion of lean meat decreased, the cost of raising pigs, Reduced economic efficiency.
