Techniques of raising clean meat with yeast for microbiology

Application of advanced techniques for raising clean meat with yeast to ferment microorganisms on biological padding to bring high economic efficiency, reduce environmental pollution, prevent possible epidemics for humans and animals .

With breeding process on biological padding , pigs are mobilized a lot, strong meat, high lean rate, beautiful color, delicious taste, favored by consumers. Not only that, padding after 2-3 years can be reused as organic fertilizer for clean agricultural production.

Raising pigs to clean meat by this method ensures environmental hygiene, preventing possible diseases for people and animals thanks to open barn design, high and airy roofs.

In addition, fermented padding is produced mainly from rice husk, non-toxic sawdust, sand and biological products, to help decompose the waste on the spot, without causing bad odors as well as adversely affecting the air. , water source.

Fermented foods are mixed with beer residues for pigs to eat, absolutely do not use industrial food. Thus, saving a lot of costs for animal feed, pigs can increase nutrition, ensure the quality of commercial meat is safe and delicious, favored by consumers.

Prepare biological padding

Thickness of padding varies with season , summer 40-60 cm, winter 60 - 90 cm. The thickness of the padding decreases due to the pig stepping on the moving process, so when refreshing, it usually increases by about 20%.

Fillers as padding are some kind of small mulch like sawdust; Rice husks, cotton seed husks, peanuts, cotton stalks, corn cobs, crushed corn stalks combine with rice husks. In preparation for a 20 m2 pigsty, the thickness of the padding is about 60 cm, 200 liters of fermentation solution, 5 kg of cereal powder must be prepared.

Fermentation solution before 1-2 days, for 1 kg of original yeast, 10 kg of cereal flour, add 200 liters of clean water, stir well, cover tightly, keep warm for 24 hours, winter may last up to 48 hours. After that, take about 2 liters of prepared fermentation solution, moist and evenly, then leave it warm. After 5 - 7 hours, spraying rice husk layer about 30 cm thick, using rain nozzle, raking until the humidity reached about 40%, evenly spraying 100 liters of yeast solution. Continue the 30 cm strip of humus, spray clean water until 20% moisture is reached, evenly spread the cereal powder on the surface of the humus. Evenly water the remaining 100 liters of fermentation solution on the surface. Flattening all sawdust, covered with tarpaulin. After a few days, under 30 cm of padding has a temperature of about 400C, has a slight aroma of alcohol, remove tarpaulin, lightly scratch the surface layer about 20 cm, about 1 day later, release the pig.

The thickness of the padding changes with the season

Techniques for incubating food with probiotics

Wet fermentation method

Often use corn bran and fermented rice bran as food for pigs . To ferment 100 kg of corn bran and rice bran is carried out as follows: Take 0.5 kg of yeast, 4 kg of corn bran into a 100 liter container of clean water, stir for 1 hour. Mix the remaining corn bran and rice bran slowly, until all the water in the bran is slightly submerged. When pouring bran into the barrel, do not fill it, leave the bran about 15 - 20 cm from the mouth, avoid after fermenting the filled food, float up and overflow. Leave the barrel open after 4 - 5 hours. The temperature is over 300C, fermentation time is about 24 hours, the temperature is below 300C fermentation time is about 24-28 hours. In summer, food after fermenting microorganisms should only feed pigs for about 2 days. In the course of use, restrict the opening of the lid, avoiding the occurrence of food contamination.

Method of fermentation and dry moisture

Requires more stringent fermentation conditions, only bran and powder can be used to ferment food . To ferment 100 kg of corn bran, rice is carried out as follows. Take 0.5 kg of probiotics and 2 kg of corn bran in a container of 40-45 liters of water, 10-15 minutes of stirring once, for 1 hour. Mix corn bran and rice bran evenly, sprinkle the fermented water evenly, mix until the bran is evenly moistened. Pour into a plastic container or bag, uncompressed, open the mouth for 5-6 hours, then cover the mouth tightly. Temperatures above 300C, fermentation time is about 24 - 36 hours; temperature below 300C, fermentation time about 36 - 48 hours. Note that when fermenting do not use plastic bags, punctured containers, limit the opening of the cover mouth, the lid of the container, avoid mold food.

Method of using food

Using microbial fermentation feed to add industrial feed to ensure adequate supply of nutrients, vitamins and minerals for pigs to gain weight faster. Choose industrial foods with protein content of over 45%. Only mix fermented food with industrial food before feeding. After mixing, leave it dry or add water to liquid to feed pigs, depending on the habit.

Composition of fermented feed with industrial feed varies with fermentation, pig breed and development stage.

F1 hybrid pig

Pigs weighing less than 15 kg: Blending with an industrial ratio of 4 to 5 parts of wet fermented food or 4 - 5 parts of dry fermented feed. Feeding with 0.7 - 1.1 kg / animal / day with wet fermented feed; 0.5 - 0.8 kg / animal / day with dry fermented feed.

Pigs weighing 16 - 30 kg: Mixing 1 part of industrial feed with 6-7 parts of wet fermented food or 5-6 parts of dry fermented feed. Feeding 1.2 - 1.7 kg / animal / day with wet fermented feed; 0.8 - 1.2 kg / head / day with dry fermented feed.

Pigs weighing 31 - 60 kg: Mix one part of industrial feed with 7-8 parts of wet fermented feed and 6-7 parts of dry fermented feed. Feed with 1.7 - 3.4 kg / head / day with wet fermented feed and 1.7 - 2.3 kg / head / day with dry fermented feed.

Pigs weighing over 61 kg: Mix one part of industrial feed with 9 parts of fermented feed or 8 parts of dry fermented food. Feed amount of 3.4 - 4 kg / head / day with wet fermented feed; 2,3 - 3 kg / head / day with dry fermented feed.

Super lean pig

Pigs weighing less than 15 kg: Mix one part of industrial feed with 4 - 5 parts of wet fermented food or 3 - 4 parts of dry fermented food.

Pigs weighing 16 - 30 kg: Mix one part of industrial feed with 5-6 parts of wet fermented feed or 4 - 5 parts of dry fermented feed.

Pigs weighing 31 - 60 kg: Mix one part of industrial feed with 6-7 parts of wet fermented feed or 5-6 parts of dry fermented feed.

Pigs weighing over 61 kg: Mix one part of industrial feed with 8 parts of fermented feed or 7.5 parts of dry fermented food.

Feed amount is similar to F1 hybrid pigs.
