To cultivate healthy pigs, the environmental issues should not be underestimated, and it is especially necessary to avoid the hazards of ammonia gas. This article will briefly describe the sources, hazards, and how to control ammonia in pig farms. Hopefully, it will help in raising pigs. Ammonia sources: Sources of exogenous ammonia The ammonia in the pig house is derived from the decomposition of organic matter such as pig manure and urine, and other harmful gases such as hydrogen sulfide, methane, carbon monoxide, carbon dioxide, and skatole are also generated during the decomposition process. The source of endogenous ammonia originates from the catabolism of porcine protein. The production of such ammonia is a normal metabolic process. Second, it is derived from the decomposition products of nitrogenous organic substances in the intestine, digestive tract mucosal epithelium, digestive tract secretions or excretions, and dead microorganisms in the digestive tract. In addition to respiratory diseases, the most serious problem is to reduce blood oxygen levels, resulting in hypoxia of the brain tissue, severely affecting the performance of the sow, and accelerating the heart rate, causing heart failure, diarrhea, and respiratory infectious diseases. Causes growth retardation and decreased immunity. Control measures include: 1. Change the structure of the pig house, install the roof or ventilation system in the pig house, and change the internal excrement into the elevated excrement. 2. Changes in feed traits, such as the change from dry powder to liquid feed, significantly reduce excrement. 3. Changing the composition of the compound feed can reduce the ammonia emissions from the manure. The use of two types of premixes 2.0 and 2.5 (low copper deodorizing and environmentally friendly series of premixes) can reduce the level of crude protein in feed and reduce the amount of protein material such as soybean meal. At this time, the conversion rate of feedstuff is the largest, and the nutrient excretion is the least. It not only saves protein resources, but also reduces nitrogen pollution, thereby reducing environmental pollution. It also promotes the growth rate of live pigs and maximizes the aquaculture benefits. 4. The use of environmental modifiers "safety care". Quickly decompose the remaining surface organic matter, adsorb metabolites, reduce ammonia concentration, greatly reduce respiratory diseases, and at the same time suppress the proliferation of harmful micro-organisms in pig houses and rebuild the micro ecological environment of pig houses.
