First, the choice of litter:
The fermentation bed includes litter material (such as corn and other plant straws, sawdust, leaves, etc.) and strains.
The litter mainly consists of: (1) sawdust + rice husk; (2) sawdust + corn stalk.
Note that corn stalks are best crushed, and sawdust produced from preservative-treated plates must not be used.
Second, the litter production steps
1, determine the thickness of the litter
A. The height of the litter layer in the fattening, spare pigs, pregnant sows, and sow sows is 80 cm in winter and 60 cm in summer.
B. The height of the bedding layer of the suckling pig and nursery is 60 cm, and the summer is 40 cm.
2, calculate the amount of material
Calculate the required amount of chaff, sawdust, and straw based on the summer and winter season, the size of the pig house, and the required thickness of the bedding.
Third, material accumulation fermentation: (10 square meters fermentation bed area as an example)
The first step: First add 50 kilograms of rice bran or bran to one kilogram of solid green Kangao ecological treasure evenly stirred. (The amount of rice bran or bran is 2-5 kg ​​per square meter)
The second step: Stir the evenly litter in the first step and stir well with a cubic dunnage.
The third step: Mix the second step of the well-mixed litter with the remaining 9 cubic feet of padding material and stir it well. In the mixing process, use one kilogram of green Kangao liquid to dilute 500-1000 kilograms of water to make the pad moisture. Stay at 40%. (How much moisture is the key, generally 40% is more appropriate, on-the-spot practice is to judge with hand padding, identification methods: hand can be grouped, loose hands, loose, finger joint water seepage)
Step 4: Build trapezoids in the pens and cover them with sacks or straw. It can be 5-7 days in summer and 10-15 days in winter (fermented aromas and steam are released).
Step 5: Spread the fermented litter and lay it flat. After the reserved chaff and saw are not mixed, cover the top and make a thickness of about 5-10cm. Then wait 24 hours before entering the pig.
If the pig runs in the circle, the surface litter is too dry and dust is present. It shows that the litter is dry and the water is not enough. Some water should be sprayed according to the situation to facilitate the normal growth of the pig. Because there is a large amount of microbial flora in the litter in the whole fermentation bed, the decomposing fermentation of microbial flora provides a good environment for the pig's healthy growth.
pay attention:
1. If pigs are found running after the pig has litter dust, it proves that the litter is dry, and the water spray can be used for humidity adjustment;
2. The suitable litter temperature in the rearing should be 17-20 degrees, and the middle can reach 40-50 degrees.
3, pay attention to moisture, litter wet will affect the fermentation effect, natural ventilation or forced ventilation can be used to dehumidify the litter bedding;
4. The most scientific and reasonable breeding density should be:
Finishing pigs (50-100kg) 1.2-1.5 square meters/each
Breeding pigs (below 50 kg) 0.8-1.2 square meters/each
Sow 2.0-3.0 square meters/each
5, in order to save the cost to solve the problem of drinking warm water in winter pigs, the plastic pipe can be bent and laid in the pad layer;
6, ecological lazy Han pig law requires that we must do a good job of ventilation, so the housing must be required to open ventilation windows and install forced ventilation equipment.
