In recent years, the rapid development of large-scale and intensive commercial aquaculture has provided mankind with a wealth of livestock products. At the same time, the intensive production of animal husbandry and aquaculture produces a large amount of manure and sewage, especially the contamination of pig farms. Since the 1990s, domestic and foreign scholars have done a lot of research work on the pig-raising technology of the fermentation bed, and they are ideal in improving the welfare of pigs, reducing environmental pollution, reducing the diseases of pigs, improving the quality of pork, and improving the production performance. The research results are of great significance to the pig industry and environmental protection.
The Ecological Breeding Technology of Golden Baby Dry Spread Fermentation Bed
The eco-pig technology of the ginba dry-sweeping fermentation bed is to organically combine the effluent excrement of pigs and the culture process, through the beneficial bacteria flora (such as yeast and actinomycetes) in the dry-sweeping fermentation bed. Bacillus subtilis, etc.) microbial fermentation of pig excrement, the feces into heat and harmless gas, to achieve the sustainable use of energy cycle, to effectively use, pollution-free emissions of ecological cycling mode of benign circulation. This breeding mode has the advantages of low cost, low material consumption, high efficiency, simple operation, and no pollution.
Application of Ecological Farming Technology of Jinbao Dry Sausage Fermentation Bed in Pig Production
Improve pig production performance
Jinbao dry-fermented bed breeding, the pig's freedom, activity space, living environment are better than the conventional cement floor, litter also meet the needs of pigs nature, so, Jinbao dry spreader bed conditions conducive to the pig tissue Organ development and health, in turn, promote their growth and muscle development. A large number of studies have shown that the fermentation bed can increase the pig's daily weight gain, reduce the feed-to-weight ratio and diarrhea rate, and improve the growth performance. In addition, the softness of the fermented mattress material allows the pig to overturn arches and feed the beneficial bacteria in the litter, which can improve the intestinal health, enhance the resistance to disease, and increase the growth performance. According to Guo Yuguang's test results, during the period from 130 to 150 days of Duomei binary hybrid pigs, when the ambient temperature is lower than 19°C, the average temperature of the fermentation bed is 19.9°C, the cement floor is 18.6°C, and the daily growth weight of the fermentation bed group The cement ground group increased by 6.4% respectively, indicating that the pigs in the fermentation bed promoted the production performance of the pigs, and the changes in the microclimate environment could promote the growth of the pigs; Qinfeng research showed that the weight of the pigs in the wood pellet fermentation bed and the distillers' grain fermentation bed group was The total weight gain, average daily weight gain, and heart weight were all significantly higher than those in the control group; Qin Ling used Japanese Luodong type biological fermentation tanks to discharge zero-emission new-type ring maintenance pigs and traditional pig-raising two different pig production methods. It shows that the ratio of traditional pig feed to feed was 2.65:1 in the 2.87:1 fermentation bed and the feed remuneration was 7.67% higher than that of traditional pigs.
Improve pig immune function
If the pig's living space is too small, it will cause negative effects such as behavioral depression and abnormal physiological functions, which will affect its immune function. The beneficial microorganisms in the fermentation bed are good immune activators, can effectively increase the activity of anti-interferon and macrophages, and stimulate the body's humoral and cellular immunity through the production of antibodies and bacteriostatic activity, thereby enhancing the body's immunity. Force and disease resistance. Pigs grow on fermented mattress materials, which can reduce stress, and feed on bacterial proteins. The disease resistance is obviously enhanced and the incidence is reduced. In winter, in order to increase the temperature of the pig house, closed and warm measures are often adopted. The relative humidity in the pig house is high, the concentration of ammonia gas is large, the immunity of the pig is reduced, and it is easy to suffer from respiratory diseases. The use of the Jinbao dry-fermenting bed feeding mode can improve the pig body. Serum IgA, IgG concentrations, significantly improve the immune function of pigs. For instance, Qin Feng’s experiment found that the serum IgA, IgG, and IgM concentrations were significantly higher in the pre-fattening pigs than in the control group, and the spleen organs of pigs were also significantly better than the control group. It has also been found that fermentation bed culture can promote the secretion of hormones (T3) and emotional substances (Ach and 5-HT), thereby enhancing the immune function of pigs.
Improve the environment in the pig house
An excellent air environment is an important condition for pigs to maintain good growth and health. If air contains harmful substances, it will not only reduce the pig's production performance, but also cause diseases and death. The eco-pig model of jinbao dry-sweeping fermentation bed, excreta and urine are digested and degraded by beneficial bacteria in organic litter, reducing the discharge of wastes and excreta, reducing the pollution of the pig industry to the environment, and obtaining good social benefits and ecology. benefit. The broiler beds in the fermentation beds are odourless, with few mosquitoes and flies, which can reduce the production of odor substances such as ammonia, nitrous oxide, hydrogen sulfide, hydrazine, and 3-methyl fluorene. Duan Qibin's research shows that the ammonia concentration in the fermentation bed group is significantly lower than that in the control group in summer, and the ammonia concentration in the spring, autumn, and winter test groups is 1.53 mg/m3, 1.25 mg/m3, and 0.40 mg/m3 lower than in the control group; The fermentation bed technology reared, the results show that the barn housing temperature than the traditional method of raising the barnhouse increased by 3.1 °C, the temperature of the pig farm is more suitable for pig growth. In addition, pigs grow on fermented mattress materials. The excretion of pig excrement is decomposed by microorganisms in the litter. The average humidity in the bed is lower than that of the concrete house by 4.5%. The relative humidity of the pig house is low and the pig's health is also high. More favorable.
The eco-pitting technology of jinbao dry-leaf-fermentation bed has achieved remarkable results in solving environmental pressures, maintaining the ecological environment, and improving economic efficiency. It has been welcomed by pig raising industries in Europe, the United States, Japan, and South Korea, and China has gradually realized that The superiority of the ecological breeding mode of the fermentation bed is also being vigorously promoted. Its economy and environmental protection have been fully demonstrated. With the development of society and people's increasing awareness of environmental protection, this technology will surely become one of the important models for raising pigs in the future.
