Method for preparing drug residue free feed for feeding live pigs

Abstract

The invention discloses a method for preparing drug residue free feed for feeding live pigs. The method comprises the steps of: preparing 1 part of bacterial strain, 0.1 part of lower polyxylose and 0.2 part of daidzein by mass, adding 10 parts of water, stirring for 30-45 minutes, and preserving the water temperature at 20-35 DEG C; preparing 100 parts of feed and 20 parts of corn steep liquor by mass and adding into a cone type stirrer together, loading into a plastic bag with a reducing valve after stirring to be uniform, stacking at a warehouse for fermentation, unpacking the plastic bag after 72 hours, pouring out, drying, and packaging. In the invention, the raw materials need no strict sterilization and can be directly inoculated and cultured, inhalation consumption is very low without exceeding 1.0 percent generally, the heat radiated during fermentation is lower, the operation is easy to control, the production process is simplified, the production cost is reduced, the equipment investment is low, a feed factory can be used for carrying out granulation production without increased cost on a feeding farm, thereby being easy to popularize.

Description

Technical field: [0001] The present invention relates to a preparation method of pig feed, in particular to a preparation method of feed for raising pigs without drug residues. Background technique: [0002] Since January 2006, the European Union has completely banned the addition of antibiotics to animal feed. Subsequently, developed countries in Asia such as Japan and South Korea have successively formulated regulations for raising livestock and poultry without antibiotics. my country's feed industry and feeding level lag behind developed countries such as the European Union by more than 10 years. Antibiotics are still widely used, resulting in the drug residue index in pork food exceeding the standard. Antibiotic residue not only affects the quality and flavor of meat products, but also affects people pose a potential hazard to physical and mental health. [0003] In recent years, my country has made many achievements and products in the research of alternative antibiotic...

Problems solved by technology

The amount of the above products added to the feed is generally on the order of 0.1%. Although it has a certain effect on the health of live pigs, the manufacturing control is very cumbersome and the production cost is very high. It needs at least 10 yuan per kilogram. It is possible to achieve antibiotic-free feeding, but the cost of feeding is high

Therefore, it is still very difficult to meet the requirement of no drug residue in the whole process of feeding pigs under the conventional feeding conditions in our country.
