When it comes to pig-producing countries, people first think of China and the United States. China's annual slaughter pigs rank first in the world, and the United States has advanced pig-breeding techniques and pig-raising systems. Many of China's large-scale slaughter companies have built in the United States. Farms, these factors are bound to let the United States rank among the big pig country. To say what other countries in the world have aquaculture technology that can compete with the United States, that is Germany. Although the land area of Germany is not large, but in the pig raising section, they have a first-rate level. It is said that a German can raise 500 pigs. This kind of pig raising efficiency has to be obliged. In addition to the high breeding efficiency, these The aspect is also worth our country's farmers to learn. Although many pigs are raised, the pig's excrement does not cause any environmental pollution. How did they do that?
First of all, German pig farms have high health requirements. In order to prevent the influence of external diseases on the health of live pigs, it is necessary to undergo strict bio-safety disinfection when entering pig farms. The floor drain of a pig house is the same as that of the feeding system. It is connected by pipes and eventually leads to a septic tank. After the pig manure is treated, it is mainly used for fertilizer production and power generation. By means of planting and breeding, “dry cow dung is more suitable for biogas power generation, and pig manure is more suitable for composting.” According to the current German Fertilizer Regulations, the use of fertilizers to prevent the excessive use of fertilizers affects the environment, especially the water body. Eutrophication pollution, the period and amount of animal manure used as compost are strictly limited. Composting was banned in the late winter and early spring, but the weather was cold and people’s demand for electricity increased. Pig manure from pig farms and cow dung from cattle farms were used together to generate electricity. Germany plans to complete the energy transition by 2050. The federal government has formulated policies to determine two major priorities. One is to vigorously develop renewable energy, and the other is to increase resource utilization. In the area of vigorously developing renewable energy sources, biomass energy such as animal excreta accounts for two-thirds of renewable energy. Compared with wind power generation and solar power generation, biomass power generation can be stored better and become more competitive without government subsidies.
Secondly, the farms are small and they also pay attention to large-scale farming. In our impression, only large pig farms are qualified to scale. In fact, the Germans did not do that. Their farms were mostly family farms. From the moment they decided to raise pigs, the pig houses they built and the farm equipment they bought were all moving in the direction of scale. of. The equipment is the most advanced, keeping is the most scientific, because the external infrastructure is done, so they want to increase the number of breeding at any time. Followed by the selection of species from the unambiguous, China's pigs are mostly outside the ternary or hybrid, and there are no strict requirements for the pig breeds. However, the Germans are not the same, the Germans are naturally rigorous, and the selection of the pigs is absolutely unambiguous. The breeds they feed are all of the finest varieties in the world, such as Duroc, Landrace and Pietrain. High lean meat, long and fast, strong reproductive ability. Both the male parent and the female parent are so excellent that the born piglet is naturally not bad. Because of the stringent requirements for selection, the survival rate of their piglets is particularly high, and there is no need to worry about raising piglets. In addition, there are no infectious diseases such as swine fever, foot-and-mouth disease, and JE. If we say that we can spend a little more money on scale, we can also do it. If we can select species, we can also pay attention to it. The control of these infectious diseases is beyond our control. It is estimated that it will not be able to catch up in more than 10 years. Germany has a perfect disease prevention and control system. The farmers do not need to worry about the prevention and control of these infectious diseases. The government will send professional technicians to manage them and pick them up from piglets. Therefore, these pig diseases do not occur in Germany at all.
