With the rapid development of large-scale breeding of live pigs, a large amount of manure produced in the breeding process is difficult to handle, and environmental pollution problems have become increasingly prominent, which has adversely affected the sustainable development of the pig industry. Pig-raising in the fermentation bed is to use the beneficial microorganisms in the fermentation mattress material to quickly degrade the pig manure, achieve the synchronization of the pig production and the manure treatment, reduce the discharge of the manure to the external environment, and effectively solve the pig-raising environment pollution problem. At the same time, the pigs in the fermentation bed do not directly contact the hard concrete floor and the accumulated excreta, and the nature of the pig's arch food litter is restored, which increases the amount of activity and is more in line with animal welfare requirements, which is beneficial to the establishment of pigs. Grow. The following is my experience in promoting the use of fermentation beds to raise pigs in practice. I hope to share with you:
First, the advantages of breeding bed breeding pigs
1. The fermentation bed can provide a clean and comfortable living environment for weaned piglets to reduce weaning stress.
2, piglets like to chase, fighting, soft bed fermentation so that piglets are not easy to fall.
3, the habit of pigs have a good arch, after weaning piglets gastrointestinal feed is not adapted, prone to diarrhea, and through the arch circle can eat beneficial microorganisms, and then the conditions of gastrointestinal microbial balance, greatly reducing the incidence of diarrhea, disease resistance Enhanced, reduced dosage, increased survival rate.
4. Compared with the conventional high-bed full-leakage nursery, the pig fur is bright and clean with good growth momentum. The air quality in the whole fermentation bed nursery was greatly improved, and the odor was significantly reduced.
Second, the disadvantages of breeding bed raising pigs
1. There are differences in the surface temperature of the fermentation bed between the different manufacturers of fermented foods. For example, the surface temperature of a piggery fermentation bed is only 22-23°C, and the surface temperature of another building reaches 26°C-28°C.
2. When the ambient temperature is lower than 13°C, the surface temperature of one of the fermentation beds is only 22°C, which can not reach the piglet conservation temperature, resulting in severe diarrhea in piglets; piglets transferred into the delivery room are easy to get together, and a large number of piglets are tied together. Weak piglets are crushed underneath or even in litter, which can cause piglets to be injured or even die.
3. When the ambient temperature is as high as 30°C, the surface temperature of the fermentation bed is high, the piglet is far away from the fermentation bed and enters the concrete floor, and some of them occupy the position of the drinking fountain, which seriously affects the water intake of the piglets.
4. The piggery in the fermentation bed cannot completely implement the disinfection and epidemic prevention procedures. Chemical disinfectants and antibiotics should not be used in pigs in the fermentation beds. However, the current large-scale swine is threatened by the disease more and more serious, more and more complex, the virus infection, the secondary infection of the bacteria, the mixed infection is more and more serious.
Third, the improvement measures:
1. Carefully select fermentation strains to ensure that the surface temperature of the fermentation bed is moderate;
2. Feeding in a small bar, feeding in a small bar at the front of the fermentation bed, feeding ten per bar
