The Modern value of traditional Pig raising essence

At the end of this post, edited by qdet at 19:40 in 2009-12-2, the modernization of pig farming continues to move forward. We must constantly sum up experiences and lessons and push through the old and bring forth the new. Looking back on the previous course, we are more likely to absorb the spirit of the times and learn from Western experience, less to review the cultural heritage of the motherland, and even to take the role of negation and exclusion. With the close to practice and the deepening of understanding, on the basis of critically inheriting the traditional pig raising experience, we began to pay attention to the modern value of the traditional pig raising essence. Factory pig raising is one of the advanced technologies of modern pig raising. In the initial stage, factory pig breeders tend to oppose modern technology and traditional technology, regarding the former as absolutely advanced, while the latter as absolutely backward. After a period of exploration, they began to have an insight into the essence of pig-raising tradition, which can be promoted and carried forward in the process of modernization. The essence of traditional pig raising has its modern value. We should have a diversified point of view, regardless of ancient and modern, Chinese and foreign, all give full play to their strengths and avoid weaknesses, to rough refinement, and better serve the modernization of pig farming. In recent years, after a period of imitating the modern western craze, the pig industry has looked back to see the modern value of the traditional pig essence, and inherited and carried forward in some technical links and achieved practical results. Many pig breeds with their own characteristics have been bred in China for a long time. These pig breeds are famous for their early maturity, tolerance to rough feeding, good meat quality and strong fecundity. In the previous stage, China paid more attention to the introduction of four major pig breeds (Landrace, Landrace, Duroc, Hampshire) and other foreign pig breeds, and now attaches importance to the research and promotion of the excellent characteristics of local pig breeds, and successfully selected Sutai pig (New Taihu pig) and other new pig breeds. Officially put into production. Traditional pig raising has rich experience in the use of green fodder. Since the modernization of pig raising, the status of green feed in pig feed has gradually declined, especially in the industrial pig farms that represent modern pig farming. However, in recent years, many pig farmers re-value green feed, even if not a large number of use, but also implement an appropriate amount of collocation, some units also actively open up the source of green feed. Six pig farms of Xiamen Minhui Food Company have an annual output of 10 000 Duliang commercial pigs, grow 8 hm2 of pennisetum, build a 100 m ~ 3 biogas digester on the mountain, use pig manure and urine to produce biogas, and biogas slurry is used to irrigate Pennisetum equisetum. First, Pennisetum equisetum was beaten with water to make straw pulp, and then blender was used to mix straw pulp and mixed concentrate to feed pigs. The weight ratio of concentrate to fresh grass was 1 ∶ 1.2. A pig with a live weight of about 25 kg was fed with grass for more than 200 kg when it was fed to 100-110 kg. With 1 hm2 per pig, 35 kg concentrate can be saved for each pig. Traditional pig raising uses bedding grass in winter. Factory pig farms use leaky floors and thermal insulation equipment. Practice has proved that the use of bedding grass can save thermal insulation electricity. Finishing pigs can also increase the growth rate. Parturient sows will not be disturbed by the nature of the grass mat. At present, some factory pig farms have used bedding grass appropriately according to the specific situation. As long as we can think about it carefully, the traditional pig essence can also shine in some fields of pig science and technology. In addition, due to the imbalance of regional economic development in China, there is an obvious lack of conditions for the introduction of modern science and technology in some areas. in these areas, the traditional pig essence has a broad space. Even in the advanced factory pig farms, it is not ruled out that the traditional pig essence can reflect its modern value in some technical links.
