Detailed Explanation of Fermentation Bed Pig Farming Techniques and Methods

Fermentation bed pig farming can improve pork quality, and applying this technique in large-scale pig farms yields very obvious economic benefits. Let's take a look below at fermentation bed pig farming techniques and methods.

1. Construction of the pig house

The pig house is an important part of whether fermentation bed pig farming succeeds or not. Generally, it is required to choose a site with a low groundwater level, with an east-west orientation, facing south with its back to the north, with ample lighting and good ventilation, open on the north and south sides, with automatic feeding troughs built on the north side and automatic drinkers built on the south side, so as to achieve the requirement of an odorless, fly-free pig house.

1. For the above-ground part of the construction, the rear wall of the pen should preferably be a 1.8 m red brick wall, with one 1.2 m × 1.5 m window every 1.5 m, at a height of about 0.1 m from the ground level, with the top 1/3 made of asbestos tiles and 2/3 made of anti-drip film, adding one skylight every 5 m, preparing shade netting in summer and sufficient straw curtains in winter.

2. The length of the pen area is not limited, but the width should not exceed 8.2 m. Leave a 1.2 m aisle along the inside of the rear wall for operations; the rest is the rearing area. Add 80 cm high wire mesh partitions for reinforcement every 4 m of length. Dig the ground down 90-100 cm deep. After digging the pit, single bricks must be laid around the pit to prevent soil from collapsing.

2. Method for making the fermentation bed

1. Raw materials: sawdust, loess, salt, stock bacteria (the "Sugong" brand microbial "Yushengjun" provided by the Changchun Edible Fungi Research Association and registered with the State Administration for Industry and Commerce)

2. Proportions: about 7 bags of sawdust per cubic meter, 30 kg of loess, 0.45 kg of table salt, 1 kg of stock bacteria.

3. Operation process: first calculate based on about 7 bags of sawdust per cubic meter, add water until, when squeezed hard by hand, water can be seen but does not drip, which is best; the water content is about 60%. Calculate the sawdust and the required amount of water. According to the measured amount of sawdust per cubic meter, add table salt and loess, put the bacteria into the calculated water, then spray it onto the mixed sawdust, mix evenly and add it into the pit, and finally spray stock bacteria once on the surface. In summer it can be used in 2-3 days, and in winter in about 7 days.

Drinking bacteria: for the first 3 days, a ratio of 1:100 (stock bacteria to water); after one week, a ratio of 1:300; every one week thereafter, the ratio increases by 300, until a ratio of 1:2000 becomes the fixed drinking amount.

3. Precautions for the fermentation bed

1. Rearing density of pigs: generally 1.2-1.5 sq m per pig. If too many pigs are raised per unit area, the fermentation state of the bed will decline and it will not be able to rapidly degrade and digest pig manure and urine.

2. Note that the bed surface must not be too dry. If it is too dry, it can cause pneumonia in pigs, so an activator can be sprayed regularly on the bed surface.

3. Pigs entering the pen must first have internal parasites thoroughly removed.

4. Close attention must be paid to the activity of soil microbial bacteria. When necessary, add an activator to regulate the activity of soil microbial bacteria to ensure that fermentation can proceed normally.

Advantages of fermentation bed pig farming

Five savings: saves water, saves labor, saves feed, saves medicine, saves electricity.

Four improvements: improves meat quality, improves immunity, advances market readiness, improves the meat-to-feed ratio.

Three nos: no odor, no fly maggots, no environmental pollution.

Two increases: increases economic benefits, increases ecological benefits.

One reduction: reduces drug residues in the animal body.

Zero discharge: manure and urine are all degraded inside the pen, with no sewage or manure discharged to the outside.
