1. Site selection requirements
Because goats like to be clean, the feed and drinking water are required to be clean and fresh, and the pens are required to be dry and ventilated. Low-lying, humid and polluted air can easily lead to parasitic diseases and hoof diseases, so it is best to choose dry, flat sand soil with sunny leeward and permeable soil as far as possible. If the terrain around the pen house is low, the ground can be treated as a "hanging-foot building" with a leaky floor, and a space of 1-2cm is left below to prevent excess water from soaking the padding, and at the same time to prevent the surrounding water from infiltrating into the fermented mattress material.
2. Preparation of padding
Generally, the thickness of the mattress for raising sheep fermentation is slightly lower than that of the fermentation bed in pigsty. The padding thickness of Gymboree dry-spread fermentation bed for raising sheep is 4 cm, and the source of padding can be sawdust alone or the combination of sawdust, rice husk and straw.
3. Preparation of strains
(1) Dosage: 1 kg of strains in Gymboree fermentation bed, which can build a sheepfold of 15-2 square meters. The area of a single pen should not be too small, it is suggested that 4-5 square meters is appropriate, and the breeding density should not be too high. It is suggested that each sheep should occupy about 2 square meters.
(2) Dilution: The strain of Gymboree fermentation bed should be evenly mixed with rice bran (or corn flour and wheat bran) according to the ratio of microbial agent: rice bran (or corn flour) = more than 1: 5, so as to spread the strain on the fermentation bed more evenly.
4, fermentation bed construction
Mix the diluted strains with the prepared padding, and multi-stage dilution can be adopted to achieve uniform effect; First, the mixture of rice husk sawdust can be padded for about 1 cm, and then the diluted bacterial material of rice bran can be evenly spread to cover it, and then the mixture of rice husk sawdust of 1 cm can be spread, and then the diluted bacterial mixture can be spread according to the above operation until the cushion reaches 4CM thick.
5. Daily maintenance
Because goats don't have the habit of pig overturning, and they also like clean and dry environment, the daily maintenance of fermentation beds is even more important. To increase the frequency of overturning and prying fermentation mattress materials, generally, the goat's feces and urine are buried once or twice a week, which is not only conducive to the smooth operation of fermentation beds, but also can keep the surface of fermentation beds clean and dry.
6. Moisture control of the bedding
Because goats like a dry environment, it is necessary to prevent water from infiltrating into the bedding, and the moisture content of the surface bedding is based on no dust.
7. Fermentation rhythm and temperature control
When fermenting, you can feel the heat when you put your hand into the inner layer below 1 cm, which is caused by the work of the fermentation bed, accompanied by the clear smell of alcohol and soil. The fermentation rhythm and temperature in barns can be controlled artificially. In order to raise the temperature and ferment quickly, one or more comprehensive measures can be taken: increasing the dosage of fermentation AIDS, increasing the thickness of sawdust layer, increasing the number of overturning and punching and ventilating, etc. The core fermentation temperature of Gymboree dry-spreading fermentation bed for raising sheep is generally around 5℃, and the surface temperature is kept at 2 degrees in winter and summer.
