Pig building and fermentation bed management essentials
Since the strains in the fermentation bed require a specific temperature and humidity environment, and the bacteria species produce a lot of heat energy when decomposing the organic substances in the feces, the temperature and humidity in the pig house are high. Therefore, the design of the ventilation system of the piggery in the pig-breeding technology of the fermentation bed is one of the key technologies for the success or failure of the technology, and the emphasis should be placed on ventilation and lighting.
The pig bed in the fermentation bed can be slightly modified on the basis of the original pig house. It is generally required that the pig house should be oriented east-west, north-facing and south-facing, with sufficient lighting and good ventilation. The north and south can be opened to facilitate the more appropriate growth and reproduction of microorganisms. Usually, the area of ​​each sty is about 25 square meters and 15 to 20 pigs can be kept. If greenhouses are used, it will save both money and money because of the low cost of greenhouses and the easier adjustment of the microclimate. In winter, when the lighting is good and the temperature is kept warm, the pig can safely pass the winter; in the summer, the sunshade film is put down, and the skirt film is shaken to cool the air.
A feeding trough and a drinking fountain are arranged at one side of the pig bar, and a water receiving container is added at the bottom of the drinking fountain to draw the leaked water out of the house so as to ensure no inflow of litter area, so as to prevent the drinking water from being wet litter.
Fermentation bed management has its own unique place, so the usual management must also be different.
Pig rearing density: According to the condition of the fermentation bed and the season, the rearing density is different. Generally, it is advisable to occupy 1.2-1.5 æ¯ per pig, and piglets can be appropriately increased in stocking density. If the management is meticulous, higher density can maintain the good condition of the fermentation bed. Taking into account the saving of bed materials and labor saving, the summer breeding density can be 1.2 ?/head and winter 1.5 ?/head.
Dry and wet fermentation bed: The fermentation bed should not be too dry, and a certain humidity will be conducive to the propagation of microorganisms. If it is too dry, it may cause pigs to develop respiratory diseases. Probiotic diluents may be regularly sprayed on the bed. Bed humidity must be controlled at about 60%, excessive moisture should be opened to adjust the humidity vents, over-wet parts removed in a timely manner.
Deworming: Before the pigs are introduced, they must use appropriate drugs to drive off the parasites and prevent the parasites from entering the fermentation bed, so as to prevent the pig from bringing the eggs back into the body and causing the disease.
Pay close attention to the activity of probiotics: If necessary, add probiotic liquids to adjust the activity of probiotics to ensure that fermentation can proceed normally. The pig house should be regularly sprayed with probiotic liquid.
Control Feeding: In order to facilitate the pig arch over the ground, the pig's feed should be controlled at 80% of the normal amount. Pigs usually defecate and pee in a fixed place, and dig pits when the excrement piles up.
Chemical drugs are banned: Chemicals and antibiotics are prohibited in pig stables to prevent the killing and suppression of probiotics and to reduce the activity of probiotics.
Ventilation: The moisture in the house is large and ventilation and ventilation must be observed.
