Porcine urine disease not only affects the hygiene of the pig house, the cleanliness of the pig body, but also makes the pig susceptible to skin diseases and affects the pig's growth and development. The pig urine fossa is mainly caused by poor cold insulation and poor feeding and management of the pig house. As long as corresponding measures are taken, pig urine fossa can be avoided. The pig house should be built on the sunny side of the leeward. The size of the pig house should be appropriate. The pig must always have enough hay above it, and it should be frequently aired to prevent it from getting wet. The pig house is also covered with plastic cloth to prevent the intrusion of cold air. Pay attention to the number of pigs in the circle. In the winter, it is best to keep only 2 or 3 pigs in a circle, because many pigs will sleep on each other in a warm place and no one will get up and urinate in the distance. Feed more dry foods each evening to reduce the number of urination. Regularly urine ice to prevent pigs from slipping and not to urinate in the compost trap. Training pigs develop the habit of urinating regularly. At the time of the night, the cabbage or other food is thrown into the pig manure pit to induce the pig to urinate. After about 10 days of continuous training to form conditioned reflexes, the pigs developed the habit of urinating regularly into the composting pits and no more urine fossa. Appropriate methods can be used to prevent or change the habits of pig urine fossa. First of all, to create a clean environment for the pig, the pig's house should be thoroughly cleaned and disinfected to kill bacteria and eliminate odors. In general, pigs urine 5 to 10 minutes after eating, lie down and rest, and urinate after 3 to 4 hours. He urinates half an hour before eating, urinates around 10 pm, and urinates after dawn in the morning. Grasp the physiology of pigs, and rush to the designated place to urinate on time, and it will become habits as time goes by. For pigs who do not love clean and do not have urination and defecation, they should be deported immediately. Generally after 7 to 10 days of training, the pigs can develop the habit of defecation and urination. The cause of pig urine fossa is cold. Conditional farmers can use plastic film greenhouses to raise pigs. Wooden beds and mat grass can also be set. Hydroponics is a subset of hydroculture, the method of growing plants without soil, using mineral nutrient solutions in a water solvent. Terrestrial plants may be grown with only their roots exposed to the mineral solution, or the roots may be supported by an inert medium, such as perlite or gravel. The nutrients in hydroponics can come from an array of different sources; these can include but are not limited to waste from fish waste, duck manure, or normal nutrients.
