Technical method of raising pigs in fermentation bed

Pig raising in fermentation bed can improve pork quality. when this technology is applied in large-scale pig farms, the economic benefit is very obvious. Let's take a look at the technical methods of raising pigs in a fermentation bed.

I. Construction of piggery

Pig house is an important link in the success of fermentation bed pig raising technology. It is generally required to choose the terrain with low groundwater level, east-west direction, north to south, full lighting, good ventilation, north and south open, automatic feeding trough on the north side and automatic water dispenser on the south side, so as to meet the requirements of odorless and fly-free pig houses.

1. The red brick wall of 1.8 meters for the back wall of the above-ground part of the enclosure is suitable, with a window of 1.2 meters × 1.5 meters for every 1.5 meters, a height of about 0.1 meters from the ground plane, asbestos tiles at the top 1 for asbestos tiles, and a skylight for every 5 meters, with a sunshade net in summer and grass curtains in winter.

2. the area of the enclosure is unlimited in length and not more than 8.2 meters in width. 1.2 meters of aisle is left in the back wall for operation, and the rest is raised area, reinforced with 80 centimeters of high-speed rail wire mesh every 4 meters long, and the ground is dug down to a depth of 90 centimeters and 100 centimeters. After digging the pit, a single brick should be built around the pit to prevent the soil from piling up.

2. The method of making fermentation bed

1. Raw materials sawdust, loess, salt and original bacteria ("Suigong" brand microbial "breeding bacteria" provided by Changchun Edible Fungi Research Association and registered by the State Administration for Industry and Commerce)

2. The proportion is about 7 bags per cubic meter of sawdust, 30 kg of loess, 0.45 kg of salt and 1 kg of original bacteria.

3. The operation process is first calculated by putting about 7 bags of sawdust per cubic meter, adding water to it by hand, it is better to see the water but not dripping, the water content is about 60%, calculate the sawdust and the amount of water required, according to the measured amount of sawdust per cubic meter, add salt and loess, put the bacteria into the calculated water, then spray into the mixed sawdust, mix evenly into the pit, and finally spray the original bacteria on the surface. It can be used for 2-3 days in summer and about 7 days in winter.

Drinking fungus: the proportion of 100% (original bacteria and water) in the first 3 days, and 300% after a week, and increased by 300% every other week, until the proportion of 1 ~ 2000 was a fixed consumption.

Matters needing attention in the fermentation bed

1. The feeding density of pigs, generally, each pig covers an area of 1.2 square meters to 1.5 square meters. If there are too many pigs per unit area, the fermentation state of the bed will be reduced, and the feces and urine of pigs can not be degraded and digested rapidly.

2, pay attention to the bed can not be too dry, if too dry will lead to porcine pneumonia, you can regularly spray active agent on the bed.

3. Pigs in captivity should thoroughly remove parasites in advance.

4. We should pay close attention to the activity of soil microorganisms and, if necessary, add active agents to regulate the activity of soil microorganisms to ensure that fermentation can be carried out normally.

The advantages of raising pigs in fermentation bed

Five provinces: save water, save labor, save materials, save medicine, save electricity.

Four mentions: improve meat quality, improve immunity, put out hurdles ahead of time, and improve the ratio of meat to meat.

Three nots: no odor, no maggots, no environmental pollution.

Second increase: increase economic benefits and ecological benefits.

One less: reduce drug residues in animals.

Zero discharge: all feces and urine are degraded in the enclosure, and no sewage and feces are discharged.
