The core message: winter pig houses, especially pigs in closed insulated pig houses, will be filled up due to poor hygiene management, accumulation of excrement and urine, fermentation of feed mat grass, decomposition of the feed, gasping of pigs, and coughing. A large number of toxic gases, such as ammonia, hydrogen sulfide, and carbonic acid gas, can seriously impede the growth of pigs, cause poor feeding habits, grow slowly, or do not grow meat. Pig diseases such as eye diseases, bronchitis, pneumonia, and diarrhea have increased significantly, dead pigs have increased, and economic losses have increased. The necessary measures should be taken as soon as possible to improve the environment.
1, house defecation
Taking indoor food and shelter and excreting urine outside house are the most effective measures to eliminate odor and moisture in pig houses. The practice is to place the animals 4 times a day and night and place them regularly before the pigs feed. The odor in the house is greatly reduced, the house can be kept dry and sanitary, the harmful gas is small, the pig's incidence rate is low, the pig grows fast, and the circle is early and the benefit is high.
2, ventilation
The most effective way to improve pig house humidity and pig house air is ventilation. The most reasonable and effective measure for ventilation and ventilation is to open a ventilation hole on the ceiling. In the cold winter, without opening the windows and doors, it is possible to expel as soon as possible from the ventilation holes a large amount of moisture and bad harmful gases in the house, in order to exchange fresh air, take away the damp odor, and purify the air in the house. However, ventilation should be controlled, and it must be properly controlled. It should be well ventilated for a good amount of time, and should be ventilated in cold days so that ventilation and insulation can be reasonably adjusted.
3, remove manure
There are a large number of pigs that are commercialized, and there is a lot of excretion of excrement. In particular, when the pigs are eating and housing and the bowel movements are in the house, the excrement must be cleaned three times a day. As long as it is not removed in a timely manner, it increases the degree of odor pollution. Ammonia stimulates the trachea, lungs, and conjunctiva of the eye and is susceptible to pneumonia and other diseases.
4, control captive density
Because the housing density is too high, the air in the house is not good, and the pigs are bullied and often bite and do not manage well. Captive density is 0.8 to 1.0 m2 per hog, which is no benefit.
5, reduce the bad gas
The basic cause of the pig manure urine odor is that the feed to feed the pig is too nutritious, cannot be absorbed, and has gastrointestinal indigestion. In the treatment of the stink odor, various medicines can be used to eliminate the stinky odor, because it is necessary to use a large amount of medicine (without use of less) and spend a lot, increasing the cost. I advocate that one is to improve the husbandry method; the other is to use less expensive or no-cost local-area substitutes for cheap self-produced or local products, such as zeolites, bentonite, and other adsorbent substances, so that they play the same role. Can greatly reduce the cost of the treatment of odor, suitable for rural pig farmers, the method is simple and practical.
6, strengthen litter management
Dry, soft and clean bedding, insulation and moisture absorption and deodorization are beneficial to the rest of the pig. Good litter should have low thermal conductivity, large dissolved heat, water solubility, hygroscopicity, and ability to absorb harmful gases. The hygroscopicity of straw and sawdust is 400% and the ammonia absorption is 06%. If you can add some zeolite in the litter, it will be better to absorb the moist fecal odor. Be diligent in your management. When a large amount of odor is sucked, it must be replaced in time to facilitate the removal of moisture and dung.
7, to prevent pig gastro-intestinal disease
Because piglets jaundice, white peony, red peony disease and pig infectious gastrointestinal diarrhea and other diseases, can cause pig diarrhea, diarrhea and dehydration, fecal odor unpleasant, is caused by environmental humidity and odor pollution, the main source. Therefore, it is necessary to strengthen the prevention of gastrointestinal diseases in pigs. Do not wait for the disease to re-treat, to prevent the emphasis on treatment, not to play passively, is the most effective measure to control the disease. Use medication as early as possible so that the pig is not sick. Because of the occurrence of jaundice and other diseases, there is a susceptibility stage of onset, ie the occurrence of diarrhea. As long as you have mastered the regularity of the susceptibility stage, you can take effective measures for sow prenatal use and piglet premedication so that it does not cause disease. If pigs do not cause rickets, they will greatly reduce the production of harmful gases such as ammonia. The effect is significant and it will do more with less.
