The fermentation bed technology has been used by many farmers and will have more or less problems in each season. Now it is winter, and the winter is facing the problem of how to treat ammonia in the fermentation bed and how to reduce it in the pig house. Ammonia smell. Huaxia Kangyuan technical experts talked about this topic today. 2, reduce the pig's breeding density, small breeding density, secretion of ammonia less, if the litter is dry, it can not dissolve excessive ammonia. 3, ventilation in the housing is poor, oxygen content is small, bacteria in the fermentation bed is oxygen-deficient, can not complete the process of fixing ammonia into bacterial protein, can only accumulate more, the final ammonia in water Get full and release it. Second, the source of ammonia in the fermentation bed The source of ammonia in the fermentation bed has two situations: 2. Ammonia in the pens is generated by the erosion and accumulation of organic matter such as accumulated excrement, feed residue and bedding. The ammonia gas is generated faster when the padding is wet, the pH is suitable for high temperatures, there is plenty of manure, and there is proper air. The concentration and content of ammonia in the fermentation bed housing depend on the temperature, stocking density, ventilation, ground layout, feeding and management, and excreta removal. Livestock and poultry excrement contains many nutrients that are not digested and absorbed by the body. Among them are proteins, amino acids, and microbial nitrogen. These substances are quickly differentiated into ammonia and released into the surrounding air under the effect of various kinds of microorganisms. . Ammonia is highly soluble in water and the concentration of ammonia in high humidity air is relatively high. According to experiments, 50 to 80 kg of pigs discharge 6 kg of excreta per day, 16 to 37 g of nitrogen, and about 60% of them are urea or amine salts that are easily converted to NH3. Through the above introduction, you know the source of ammonia in the fermentation bed, how to reduce the ammonia smell in the fermentation bed in the winter: strengthen ventilation and reduce the breeding density. Pigs' urine is better fermented. Canned Green Peas,Green Peas Canned,Green Peas Tin,Canned Green Peas Canned ZHANGZHOU TAN CO. LTD. , https://www.zztancan.com
I. Analysis of ammonia odor in fermentation beds
1, ammonia dissolved in water, 1 litre of water can dissolve 500L water, dry fermentation bed moisture content is low, can not dissolve the remaining ammonia, can not be released, so can smell.
1, one is the ammonia in the gastrointestinal tract, origin and excrement, digestive and other gastrointestinal products, urine ammonia is mainly in the form of urea, very simple other urease hydrolysis, catalytic generation of ammonia and carbon dioxide, in the livestock and poultry excrement, We can smell the ammonia smell of red nose that is the reason. The ammonia of manure exists mainly in the form of organic matter and is not simply differentiated, but it is also an important and stable source of ammonia in the process of its formation.
