Abstract

The invention relates to the technical field of pig raising, in particular to a selenium-rich pig raising technology. The technology includes the steps of firstly, establishing a pig farm; secondly, determining the raising density; thirdly, conducting conventional raising; fourthly, conducting selenium-rich raising. The selenium-rich raising step includes the substeps of starting to feed pigs with a natural selenium-rich green feed (the selenium content of 0.10-0.40 mg/kg) 60 days before slaughtering, and feeding the pigs with a sufficient amount of selenium-containing feed every day according to a normal raising technological standard until slaughtering; or the selenium-rich raising step includes the substep of starting to feed the pigs with an artificially-prepared selenium-containing feed 60 days before slaughtering. A method for preparing the selenium-containing feed includes the steps of preparing 400 kg of feed for every 40 g of meat egg type selenium-containing nutrition powder, feeding the pigs with a sufficient amount of selenium-containing feed continuously for 45 days or longer according to the normal raising technological standard, stopping feeding the pigs with the selenium-rich feed 10 days before slaughtering. The pork pigs raised through the selenium-rich pig raising technology are environmentally friendly, fresh and tender in meat and suitable for popularization in the field, and the selenium content is up to standard.

Description

technical field [0001] The invention relates to the technical field of pig raising, in particular to a selenium-enriched pig breeding technology. Background technique [0002] Selenium is one of the essential trace elements in human life activities. It is an antioxidant in the human body, can improve human immunity, and has various biological functions. As the main meat food of most people in my country, pork has a long-standing eating habit. As an animal food, pork has a good accumulation effect on selenium. Increase the human body's demand for selenium by eating selenium-enriched pork. The selenium-enriched pork currently produced in the market is simply fed with sodium selenite or yeast selenium in the feed to feed pigs. The disadvantage is that the absorption and utilization rate is low. Therefore, the selenium content in the meat is low, which cannot be used to supplement selenium. Effect. Contents of the invention [0003] The purpose of the present invention is to...
