Abstract

The invention relates to a method for detecting the loading quality of mixed feed additive sodium selenite, and belongs to the technical field of feed additive detection. Through the steps of sample weighing, screening, screening material weighing, detection of Se content percentage, firmness determination and other steps, the present invention enables production enterprises and users to have a feasible evaluation method for identifying product quality, which makes up for the existing detection standards. If the above detection methods are combined with the detection items in the existing standard HG2937-1999 "Feed Grade Sodium Selenite", the quality of the mixed feed additive sodium selenite can be more completely described and a more complete description can be formed. Complete evaluation system.

Description

technical field [0001] The invention relates to a detection method of a feed additive, more specifically, the invention relates to a detection method of the loading quality of a mixed feed additive sodium selenite, belonging to the technical field of feed additive detection. Background technique [0002] In the feed processing technology, the amount of sodium selenite added is very small, and the maximum limit of selenium in compound feed or complete diet is only 0.5 mg / kg (according to the regulations of the Ministry of Agriculture of the People's Republic of China Announcement No. 1224); In order to ensure the uniform distribution of selenium in the feed, it is necessary to improve its dispersion. Carry the high-concentration sodium selenite raw powder with a carrier, refine and dilute it into a low-content mixed feed additive sodium selenite, and then It is allowed to enter the production of subsequent additive premixes and compound feeds. [0003] According to the princ...
