Abstract

The present invention provides a feed additive capable of reducing odor emission for pigs. The additive comprises the following raw materials in parts by weight: 6-10 parts of refined lobster shell powder, 8-12 parts of aspen flowers, 7-11 parts of grape residues, 9-13 parts of honeysuckles, 5-9 parts of folium artemisiae argyi, 8-14 parts of apple pectin oligosaccharides, 4-8 parts of bromelain,and the balance of a carrier, wherein the carrier consists of wheat flour and zeolite powder. The additive can effectively prevent generation of odor substances in digesting and decomposing processesof nutrients in pig intestines, at the same time effectively regulates intestinal flora balance and intestinal development of the pigs, promotes full digestion and absorption of the nutrients, reducesemission of undigested nutrients and reduces odor generation in pens.

Description

technical field [0001] The invention relates to a feed additive, in particular to a pig feed additive capable of reducing odor emission. Background technique: [0002] Odor generation in pig farms has always been a difficult problem for Chinese and foreign researchers, especially from traditional free-range farming to large-scale and intensive development. The expansion of pig farm scale will not only pollute the environment, but also bring inconvenience to the lives of surrounding residents. . Odor in pig farms mainly comes from the excrement of pigs, the anaerobic decomposition of wasted dead and the gas produced by pigs’ respiration. The excrement and urine are the main pollutants in pig farms. Most of the odorous substances are derived from excrement and waste through microbial metabolism. It is known that there are more than 230 kinds of odorous gases produced by pig farms, mainly including ammonia, hydrogen sulfide, methylmercaptan, volatile fatty acids, indole, meth...
