Problems solved by technology

The most widely used technology for treating livestock and poultry manure is anaerobic treatment. After the pig farm manure is treated by anaerobic technology, 40-90% of the organic matter in the sewage is degraded, but the process of anaerobic digestion has almost no effect on ammonia nitrogen. Removal effect, the biogas slurry containing a large amount of ammonia nitrogen cannot be discharged directly, and must be further treated, but the current basic idea for treating pig farm sewage is to use terminal treatment methods, that is, microbial flocculation or adsorption, electrochemical oxidation and other methods, but these methods There are also problems such as high cost, long time consumption, and a large amount of space, which cannot fundamentally effectively solve the problem of ammonia nitrogen pollution in fecal water

Abstract

The invention discloses a feed additive with functions of reducing ammonia nitrogen content in pig manure and promoting digestion, and belongs to the field of feed additives. The feed additive is prepared from, by weight, 18-36 parts of a fermented Chinese herbal preparation, 12-18 parts of bacillus powder, 8-12 parts of lactobacillus powder, 16-20 parts of calcium oxide modified zeolite powder and the balance carrier, wherein the carrier is one or two of rice husk powder and wheat middling. The feed additive can effectively improve the digestion and absorption capacity of ammonia-containing substances in daily ration of pigs, reduce the ammonia nitrogen emission in the pig manure, improve the air environment in a pig house and reduce the difficulty in treating breeding wastewater, and also has the functions of improving the microbial community structure in the pig intestinal tracts, and improving the health level and growth performance of the pigs.

Description

technical field [0001] The invention relates to a feed additive, in particular to a feed additive which reduces ammonia nitrogen content in pig manure and has the function of promoting digestion, and belongs to the technical field of feed additives. Background technique [0002] According to statistics, the number of large-scale livestock and poultry farms in my country exceeds 35,000, of which pig farms account for 27%, and the total amount of pig manure is as high as 1.5 billion tons. The environment has caused huge pollution, and it has the characteristics of large output, high ammonia nitrogen content and organic matter. Nitrogen, phosphorus, and organic matter in pig farm wastewater will flow into natural water bodies through rivers or penetrate into the ground through soil, resulting in eutrophication of natural water bodies, and accumulation of inorganic salts in the soil, causing soil compaction and salinization, and reducing soil quality. Pig farm manure often has a...
