Research on the creation and application of deodorizing and carbon reducing feed formulation for fattening pigs based on in vitro fermentation model

With the rapid development of livestock and poultry breeding in China, the contradiction between the odor emission caused by pig breeding and the high standard management of environmental pollution and the people's demand for a better living environment is becoming increasingly prominent. The investment and operation cost of program control deodorization and end deodorization put pressure on enterprises, and the research of deodorization and carbon reduction from the source of feed is urgently needed. The in vitro fermentation model can simulate the intestinal digestion process of pigs, and preliminarily evaluate the effects of different feed materials on the intestinal flora structure of pigs and the emission reduction effects of odor and greenhouse gas. Therefore, this study combined with in vitro fermentation model and pig breeding experiment, from the source of the selection of feed raw materials to reduce odor and carbon, to create a live pig odor and carbon reducing feed formula.
