In winter, due to poor hygiene management, accumulation of excrement, feed mat grass fermentation, decomposition, and pig gasping, coughing, etc., piggery, especially enclosed piggery, contains large amounts of ammonia, hydrogen sulfide, and other toxic and harmful substances. Gases cause pigs to have poor appetite, slow weight gain, pig eye disease, respiratory inflammation and diarrhea, and an increase in dead pigs. Measures should be taken to improve the environment as soon as possible. 1. Eating and drinking outside the defecation training barn and defecation outside the house is the most effective measure to eliminate odor and moisture in the pig house. The practice is to place the pigs outside the defecation line before the feeding time, at regular intervals and at regular intervals. , and then rushed back to home feeding. 2. Ventilation and ventilation A good way to reduce the humidity of the piggery and improve the air in the pigsty is to use ventilation and ventilation. The most effective measure for ventilation is to open a ventilation hole on the roof of the ceiling so that the door can be opened without delay. A lot of moisture and bad gas are discharged and fresh air is exchanged. However, ventilation should be controlled, sunny, warm days and more ventilation, cloudy, cold days, less ventilation, ventilation and insulation to achieve coordination. 3. Excrement removal The implementation of intensive production of commercial pig farms is large. The pigs excrete a lot of feces, especially if the pigs are eating and housing and the bowel movements are carried out in the house, they must adhere to the excrement 3 times a day. Even if only one stool is not removed in time, the odor pollution will be significantly increased, thereby stimulating the pig's trachea, lungs, and conjunctiva of the pig to become ill. 4. Controlling the captive density If the captive density is too high, the air in the house is not good, and the pigs are severely bullied and bite, and management is difficult. Captive density is 0.8 to 1 square meter per pig. 5. The main reason for the reduction of bad gas caused by pig manure urine odor is that the nutritional content of the diet is too high or the pig is indigestion, so that the feed cannot be fully absorbed. In order to save money, do not use chemicals to deodorize, you can improve the feeding methods, such as appropriate to reduce the nutritional level of feed, in the feed to add digestive enzymes and other methods to promote the digestive rate of pigs on the feed, but also can be used cheap local products or Products such as zeolites, bentonites, and other adsorbent substances replace chemicals. 6. Strengthen litter management Dry, soft and clean litter insulation and moisture absorption and deodorization are beneficial to pig rest. Good litter should have characteristics such as low thermal conductivity, heat dissipation, water solubility, hygroscopicity, and high adsorption (absorbing harmful gases). The hygroscopicity of straw and sawdust is 400%, and the ammonia absorption is 0.6%. It is very suitable for dehumidification and deodorization in winter in rural pig farms. It would be better if some zeolite is added to the litter. The litter should be grounded frequently, and should be promptly replaced when the humidity and odor are large. 7. Prevention of porcine gastrointestinal tract diseases such as jaundice, white peony, red peony, infectious gastroenteritis, infectious diarrhea and other diseases can cause pig diarrhea, diarrhea and dehydration, the stool odor unpleasant, but also environmental moisture and odor pollution The main source of the disease is therefore the prevention of gastrointestinal diseases in pigs. Because the occurrence of diseases such as Astragalus has a susceptibility stage, as long as this rule is mastered, effective measures such as prenatal antenatal administration and piglet premedication can be adopted to prevent the disease from occurring, which will have a multiplier effect. A key doorknob lock. This is a simple doorknob that includes an internal lock that is operated by inserting a key into the lock component. Turning the key makes it possible to lock and unlock the door, effectively limited access to the building to those who have keys that fit the lock. Different surface treatments are acceptable.
