Technology of raising sheep in fermentation bed
The benefits of raising sheep in fermentation bed:
When it comes to raising sheep, everyone knows that the sheep pen is full of stench and flies are flying all over the sky, which not only pollutes the environment, but is also not good for the health of the sheep. Growth, however, the fermentation bed sheep raising technology has changed this situation.
, reduce infrastructure costs and improve land utilization. It eliminates the investment in manure treatment systems (such as biogas digesters, etc.) that are indispensable in traditional sheep raising models, and improves land utilization efficiency.
, Reduce operating costs.
Saving labor. There is no need to flush the pen every day.
Save water. Since there is no need to flush the pen, water can be saved.
() Save feed.
Sheep manure generally only takes three days to be decomposed by microorganisms on the fermentation bed. The manure provides rich nutrients to microorganisms, prompting beneficial bacteria to continue to multiply and form bacterial proteins. When sheep eat these bacterial proteins, they not only supplement Nutrients can also improve immunity. In addition, since microbial preparations are added to the sheep's feed and drinking water, there are a large number of beneficial bacteria in the gastrointestinal tract. Some cellulases and hemicellulases in these beneficial bacteria can break down the cellulose and hemicellulase in the straw. Using this method of breeding can increase the proportion of roughage and reduce the amount of concentrate, thereby reducing the cost of feeding. In addition, sheep have a comfortable living environment and fast growth rate, so they can generally mature days in advance.
According to production practice, the feed savings are generally above.
Reduce drug costs. The sheep live on the fermentation bed, are healthier, are less likely to get sick, and reduce medical costs.
Save energy. Raising sheep in a fermentation bed is warm in winter and cool in summer. There is no need to use floor heating, air conditioning and other equipment, which greatly saves energy. In winter, the heat generated by fermentation can bring the surface temperature to about 10 degrees Celsius, which solves the problem of heat preservation in the pen. In summer, the problem of heat in the pen is solved just by simple ventilation and shading of the pen.
3. After the litter and sheep excrement are mixed and fermented, they are directly turned into high-quality organic fertilizer.
It improves the quality of mutton and has a competitive advantage in the market. Currently, for enterprises that use this method to raise sheep, the purchase price of sheep per kilogram is higher than that of ordinary methods. In the consumer market, the price of sheep liver is several times higher than that of ordinary methods.
The advantages of the ecological and environmentally friendly sheep raising method are summarized as follows: five provinces, four improvements, three nothings, two increases, one less, and zero emissions.
Five provinces: save water, save labor, save materials, save medicine and save electricity.
Four tips: improve the quality of mutton, improve the resistance of raw sheep, sell them early, and increase the meat-to-material ratio.
Selection of fermentation bed materials:
The litter materials for raising sheep in fermentation beds are similar to the litter materials for raising pigs in fermentation beds, including sawdust, rice husks, peanut shells, cottonseed husks, corn cobs, and corn stalks. It is composed of two or more of them. The proportion of litter is very flexible and can be adjusted appropriately according to the waste resources of local crops. The following is an example:
One way: use all straw to raise pigs in a fermentation bed. The effect of using all straw is not good, and the relatively inert sawdust should be used mainly. However, raising sheep in a fermentation bed is different. Pigs are omnivores, and their feces contain more nitrogen. If all straw is used, the straw will be easily destroyed quickly. Decomposition and deterioration, and sheep are herbivorous animals, and the nitrogen content in their feces is significantly less than that of pig manure, so the fermentation bed sheep litter can be made of straw.
Litter ratio: The fermentation bed is laid in three layers. The bottom layer is made of straw, the middle layer is made of whole corn stalks, and the top layer is crushed corn stalks. The thickness of each layer is about 3, and each layer is laid Evenly spray the Yijiayi fermentation bed bacteria liquid diluted with water. The dilution ratio is: about 100%, and the final humidity is controlled to about 10%.
Another method: Use the sawdust and straw method. Sawdust is something inside the wood. It is clean and hygienic. In method one, the top layer of crushed corn straw is replaced with sawdust. The sheep can sleep on it and it will still be very comfortable. .
The breeding density of sheep raised in fermentation beds
One is the number of sheep raised per unit area. The density cannot be too high. If the density is too high, the amount of feces and urine will be too large, and the draft of the fermentation bed will reach saturation. When the fermentation bed is wet, it will have an impact on the fermentation bed, and the fermentation effect will be bad. In fact, the reason is very simple. We know that sheep feces are nutrients for microorganisms in the litter. If there is too much feces, there will be excess nutrition, and the microorganisms will digest it. No, it will naturally not be fully decomposed, so it will not be able to function as a fermentation bed. If there is less feces, the microorganisms will have insufficient energy due to insufficient nutrients, and they will not be able to ferment and decompose well. Generally, the breeding density of young sheep is controlled at about 1 to 1 square meter of floor space per head, and the stocking density of adult sheep is controlled to about 1 to 3 square meters of floor space per head.
That is to say, in order to allow the feces to be obtained Timely decomposition, when farmers use fermentation beds to raise sheep, the stocking density should be appropriately adjusted according to the different growth stages of the sheep and the individual size of the sheep. Like pigs raised on fermentation beds, the stocking density of sheep raised on fermentation beds is generally Yes. About square meters.
Routine maintenance and management
Everyone knows that pigs have the habit of arching in fermentation beds. The pigs arch back and forth every day, and at the same time they turn the fermentation bed materials and make the microorganisms grow. The flocks are more evenly distributed and fully distributed, but raising sheep in fermentation beds is different. At this time, we have to think of a solution.
After the sheep have eaten enough, they need to drink water. We set the place where the sheep eat and the place where the sheep drink water in two different directions of the sheep house.
After the sheep have finished eating, they need to drink water. You have to walk a few more steps to the opposite side. When the sheep are full, they drink water. After drinking the water, they come to eat. In this regard, it invisibly balances the entire sheep bed. Why do the sheep move back and forth? Can it play a balancing role in the sheep bed? If you let the sheep stay in one place, the fermentation bed will be soft in one place and strong in another place, and the bed will be uneven. If the sheep are allowed to move around like this, the uneven problem on the fermentation bed will be solved, and the sheep will move around. , the hooves will bring up that litter, so to a certain extent, it's also a turning.
Another function, drinking water and eating food back and forth, can make the feces and urine excreted by the sheep evenly spread on the fermentation bed, which is conducive to the decomposition of its feces and urine. Sheep defecation is not fixed, and they poop wherever they go. Originally, dispersing defecation in this way is good for the decomposition of the fermentation bed, but sheep are very lazy. They usually either stand or lie down, and they move lazily, so their defecation is very uneven. Like Lao Wu's sheep, they eat food on one side. The drinking water is on the other side. When the sheep are forced to move back and forth, the feces is discharged relatively evenly. The feces is evenly distributed and decomposed more fully.
Manual management
Once the feces are dispersed in a timely manner, the feces that are too concentrated are dispersed to make them more evenly distributed, and the feces are buried under the litter at the same time to facilitate faster Although pigs can move and turn over litter, this role is limited after all. Artificial management and care such as manure removal is still indispensable. This is especially true for raising sheep. Manure removal takes at least two days. Do it once.
2. Turn over the litter in a timely manner. The purpose of turning is to mix the feces and the litter evenly, so that the fermentation is more complete and the feces is decomposed more thoroughly. Usually, you can turn the litter in a small area in conjunction with the loosening of feces to make the feces evenly distributed. After a period of time, the litter should be deeply turned over once a month and a half to two months. This will play a role in ventilation and ventilation. , break the hard things into pieces.
