Breeding technology and development trend of ecological pig

Release time::2015-5-5 Column:Special Report Click:705

The ecological pig is widely implemented nationwide by the ecological farming model, advanced farming technology, can make the pork quality, taste and quality and safety aspects are significantly improved, not only to ensure the food safety of consumers, but also to reduce the industry on the environment caused by pollution, promote aquaculture eco benefit.
1 the significance of ecological pig breeding
1.1 is conducive to promoting the improvement of the quality of pork
In traditional breeding technology, dietary copper, zinc excess metal elements and other antibiotics, the pork quality influence, it is harmful to food safety of consumers. Some farm farming mode in the scale effect, excessive pursuit of growth rate and index of lean pork pig, while ignoring the pork color, taste. The ecological pig farming, to avoid these problems, to avoid the traditional breeding technology in pork residues of harmful substances, improve the quality of pork.
1.2 to achieve better environmental benefits
The farm every year to produce a large amount of pollutants, such as pig manure and sewage, if these pollutants can not be effectively treated, will cause serious pollution to the surrounding environment. The ecological culture of the development of technology, can make full use of biogas energy waste on the pig fermentation, and then use the biogas produced to provide fuel for farmers living at the same time, through the fermentation biogas slurry can be used as assistant fertilizer used to water plants, reduce the amount of calls, not only solve the problem of pollution, but also can promote the full use of energy and resources.
1.3 to meet the needs of market economy
Ecological pig farming has become an important trend of culture market, under the condition of market economy, ecological pig farming to scale and the direction of professional development, to promote the improvement of the quality of pork products, and promote the breeding unit market competitiveness, create more favorable conditions for China's pork products to the international market.
2 ecological pig breeding technology
2.1 genetic improvement technology
At present, our country has introduced some foreign high-quality varieties in aquaculture ecological pigs, fast growth rate, high lean percentage, but not in taste and flavor, fully meet our needs of the masses; and some areas of domestic ecological pig farming has better performance in taste and flavor, but in the growth rate and lean rate is low, therefore, need through quality breeding and hybrid technology, realize the effective combination of high-quality varieties, so as to provide basic genetic basis for sustainable development of Chinese ecological pig breeding.
2.2 ecological breeding technology
In the process of ecological breeding pigs, to take into account the farms surrounding environment and climatic conditions, the use of early weaning isolation international advanced segment feeding technology, scientific isolated of sows and piglets, the implementation of different feeding system in accordance with the growth stage. At the same time, the ecological pig to carry out appropriate stocking, stocked in piggery near the hillside or grass, to ensure the quality of pork.
2.3 remote monitoring technology
In the process of ecological pig breeding, the installation of automatic monitoring controller can be advanced in pig house, and the related parameters of ecological pig farming to be set up, the pigsty internal temperature, humidity and other environmental factors to implement all-weather surveillance, every 10min monitoring data will be sent to the system database. Aquaculture personnel through database technology, to monitor the piggery environment, and make timely adjustments to ensure that, in the best condition in piggery environment. At the same time, the information can be related to the ecological pig, such as information, health status, immune varieties combination, if the outbreak can be quickly traced back to the source, reduce losses.
The comprehensive utilization of biogas 2.4
Ecological pig breeding places should choose the terrain is relatively high, and well ventilated area, Digester Construction position should be relatively low, in favor of the pollutants in the piggery smoothly discharged into the biogas pool. After fermentation of biogas digesters, can be a lot of pollutants by killing bacteria, fermentation to produce biogas can provide energy for farmers such as cooking, biogas can be used as organic fertilizer, irrigate crops, reducing the amount of fertilizer, the increase in indirect economic benefits.
3 of China's ecological pig farming development trend
3.1 company + base + farmers farming model
This cultivation mode is a mode used in the ecological farming industry in more, this model in the feed, epidemic prevention and procurement and other aspects are in accordance with the unified requirements and regulations, the company provides relevant materials and varieties to farmers. But it also has some disadvantages, can ensure the quality of pork, but did not fully achieve the scale of production, and the real ecological culture still has a certain gap, while the welfare and efficiency of farmers is still lack of perfect management system.
3.2 natural grazing and breeding combination mode
This model make full use of natural resources, provide wider venues for the ecological pig, also used more natural food in the feeding mode, this mode can retain the original ecological culture of the maximum, while the emission of pollutants to animal manure plants around irrigation, reduce fertilizer and pesticides, to ensure the ecological culture environment.
3.3 dimensional culture model
The way to achieve the use of three-dimensional breeding breeding space to the maximum, to feed as the lead, the groups of different animal science series, one for the formation of the food chain, its main purpose
