Seven Measures for Prevention of Fecal Odor Pollution in Pigs in Winter and Spring

In the winter/spring (early spring) season, many pig farmers are not able to keep up with the hygiene management, excrement accumulation, feed mat grass fermentation, decomposition, and pig asthma, cough, etc. Ammonia, hydrogen sulfide and other toxic and harmful gases, pigs poor appetite, slow weight gain, pig eye disease, respiratory inflammation and diarrhea increased significantly, more dead pigs. To this end, the measures for controlling fecal odor pollution in winter and spring are described as follows:

First, outside the defecation training in the piggery, food and shelter, outside the defecation is the most effective measure to eliminate odor, moisture in the piggery, its practice is every time day and night four times, fixed point in the feed before the pig rushed outside the row defecation , and then rushed back to home feeding.

Second, ventilation ventilation to reduce the humidity of the piggery, improve the air quality of the pig house is a good way to ventilate, and ventilation and ventilation is the most effective measure is to open a ventilation hole in the ceiling, so that you can quickly open the door without opening the door 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.

Third, the removal of manure The implementation of intensive production of the general population of commercial pig farms, pigs excreted more feces, especially in pigs to live, bowel movements are carried out in the case, must adhere to cleaning manure 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.

Fourth, control the captive density If the captive density is too large, the air in the house is not good, and the pigs are severely bullied and bite, and the management is not good. Captive density is 0.8 to 1 square meter per pig.

Fifth, to reduce the bad gas caused by pig manure urine odor is the root cause of dietary nutrient content is too high or pig indigestion, resulting in feed can not 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.

Six, to strengthen the management of litter Dry, soft, clean mat insulation and moisture absorption and deodorization is conducive 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.

VII. Preventing porcine gastrointestinal tract diseases such as jaundice, white peony, red peony, infectious gastroenteritis, infectious diarrhea and other diseases can all cause pig diarrhea, diarrhea, and dehydration. The feces can become odorless and become environmental humidity 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.
