Microbial fermentation pig feed and preparation process thereof

Abstract

The invention discloses a microbial fermentation pig feed. The microbial fermentation pig feed is prepared from the following raw materials in parts by weight: 20-30 parts of barley flour, 15-20 partsof bran powder, 20-25 parts of corn cob powder, 10-15 parts of beans, 8-10 parts of fish meal, 15-20 parts of potato powder, 15-20 parts of vegetables and fruits, 2-4 parts of sodium bicarbonate and10-15 parts of a bacterial solution. A preparation process of the microbial fermentation pig feed comprises the following steps: 1) firstly soaking the barley flour, the bran powder, the corn cob powder and the beans in water, and then adding the fish meal and the potato powder; 2) adding the bacterial solution into a dilute solution in the step 1), uniformly stirring and performing aerobic fermentation; 3) pouring an aerobic fermentation raw material solution in the step 2) into a sealed fermentation tank and performing anaerobic fermentation; 4) heating and sterilizing a feed in the step 3);and 5) adding vegetable and fruit juice into the sterilized and fermented feed, and then adding the sodium bicarbonate to obtain the microbial fermentation pig feed. The microbial fermentation pig feed disclosed by the invention has the advantages of low cost of the raw materials, high nutritional value, easiness in absorption after fermentation, different treatment according to the properties ofthe raw materials and better homogenization of the raw materials.

Description

technical field [0001] The invention relates to the technical field of fermented feed, in particular to a microbial fermented pig feed and a preparation process thereof. Background technique [0002] The feed made from roughage through microbial fermentation is called fermented feed. The roughage available for fermentation includes bran, rice bran, straw, grass, various cakes (meal), pomace, distiller's grains, etc. Common breeding feeds can only make pigs grow rapidly, but cannot provide various nutrients needed for pig growth. Common pig feeds have problems such as lack of nutrients, toxins and a large amount of antibiotics. Therefore, the health status of pigs fed with common feed is poor, and the quality and food safety of pork are poor. Although fermented feed can meet the nutritional needs of pigs, due to different raw materials, the raw material fiber and the degree of fermentation required are different. Even some raw materials are rich in nutrients, but they need ...

Problems solved by technology

Even some raw materials are rich in nutrients, but they need to be softened before they can be fermented, otherwise the fermentation bacteria cannot grow in the early stage
