Can sawdust and McMuffin be used as fermented beds for raising pigs?

Fermented bedding is the most critical part of fermented bed pig rearing, the scientific combination of bedding raw materials can achieve the purpose of reducing the intensity of management, reducing the occurrence of epidemics, and increasing the benefits of pig rearing. Theoretically, all organic materials can be used to make bedding, but from the point of view of using efficiency and practical application effect, usually should choose the carbon supply strength, carbon supply capacity balanced and long-lasting, as well as permeability, adsorption of good materials for the main raw materials, such as sawdust, rice hulls, straw powder, etc.; At the same time, in order to ensure that bedding production process of biological fermentation process and effect, often choose some other raw materials as auxiliary raw materials, such as bran, rice bran, cake meal, fresh pig manure and so on. Meanwhile, in order to ensure the biological fermentation process and effect of bedding production, some other raw materials are often chosen as auxiliary raw materials, such as wheat bran, rice bran, cake meal, fresh pig manure, etc. The ideal ratio of fermented mattress is 50% sawdust, 30% rice husk and 20% straw.

Bedding production

Bedding production methods according to the production of different places can be generally divided into: centralized unified production and direct production of two kinds of pig houses.

The centralized unified production of bedding is outside the house site unified mixing, fermentation production of bedding. This method can be operated by larger machinery, which can be operated freely and efficiently, and it is suitable for large-scale pig farms, and it is usually adopted in the case of making new bedding. Direct production in the pig house is a very common method. That is, in the pig house by column of hulls, sawdust, pig feces, rice bran and second rotting agent mixed evenly after use. This method is less efficient, suitable for small-scale farms, or part of the barn bedding used for a long time looks very old and bedding condition is very poor and not conducive to the growth of pigs, usually can be used in this way.

1, determine the thickness of bedding

A. Fattening, reserve pigs, gestating sows, delivery sows barn bedding layer height of 2000px in winter, 1500px in summer.

B. Suckling pig, nursery pig barn bedding layer height of 1500px.

2, calculation of bedding

According to the different seasons of summer and winter, the size of the area, and with the required bedding. According to the different summer and winter seasons, the size of the pig house, and the thickness of the required bedding material, calculate the required amount of hulls, sawdust, straw.

Simply put, the amount of fermented bedding is 150kg per square meter, and the amount of fermentation fungus is 150g per square meter, and the feeding density is 1.2 to 1.5 square meters per pig.

3, bedding pile fermentation (10 square meters of fermentation bed area as an example)

10 cubic meters of bedding, 20-50kg of rice bran or bran (the amount of rice bran or bran per cubic meter is 2-5kg) and 10kg of cornmeal add 1kg of Le Bei Feng special strain of fermentation beds (2 packets) to fully mix the mixture, and in the process of mixing the water is sprayed constantly, so that bedding moisture is maintained at 40%. Keep the moisture of the bedding at 40%. Moisture how much is the key, generally 40% is more appropriate, the field practice is to use the hand to grab the bedding to judge, hand grasp can be into a ball, loose both scattered, no water seepage from the finger cracks.

In the enclosure piled into a trapezoidal shape, covered with sacks or straw, 2-3 days in summer, 3-5 days in winter can be (fermentation aroma and steam dispersal).

Spread out the fermented bedding and spread it out, then mix it with reserved husk and sawdust, cover the top and level it out, the thickness is about 5-250px or so, then wait for 24 hours before you can enter the pigs.
