Winter pigs strictly control fecal odor pollution

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. Go outside the row. The most effective measure to eliminate odor and moisture in the pig house is to store food inside and outside the pig house and discharge the defecation. The practice is to rush the pigs to the defecation before each feeding, and then chase them back. Feeding inside. 2. Ventilation. A good way to reduce the humidity of piggery and improve the air in the pigsty is to ventilate and change the air. The most effective measure for ventilation and ventilation is to open a ventilation hole on the ceiling so that the large amount of moisture and defects in the house can be quickly eliminated without opening the windows and doors. Exhaust gas and exchange fresh air. However, ventilation should be controlled, sunny, warm days and more ventilation, cloudy, cold days, less ventilation, ventilation and insulation to achieve coordination. 3. Remove manure. The general population of commercial pig farms with intensive production is large, and there are many feces excreted by the pigs. In particular, when the pigs are eating and housing, and bowel movements are carried out in the house, they must adhere to the excrement three 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. Control 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 it is difficult to manage. Captive density is preferably 0.8 to 1 square meter per pig. 5. Reduce bad gas. The basic cause of pig manure urine odor is excessive nutrient content of the diet or indigestion of the pig, 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. The use of dry, fluffy, clean bedding insulation and moisture absorption and deodorization is beneficial for 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. Prevent pig gastrointestinal diseases. Diseases such as jaundice, white peony, red peony, infectious gastroenteritis, and infectious diarrhea can all cause pig diarrhea, diarrhea, and dehydration. Their feces are unpleasant and become a major source of environmental humidity and odor pollution. Therefore, they must be strengthened. 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.
