Abstract

The invention relates to a method for detecting loading quality of mixed-type feed additive grade sodium selenite, and belongs to the technical field of feed additive detection. Through sample weighing, screening, screened material weighing, Se percentage measuring, firmness determining, and other steps, a feasible evaluation method for identifying product quality by production enterprises and users is provided, and absence of present detection standards is made up. If the method is utilized in combination with detection items in the present standard that is HG2937-1999 Feed-Grade Sodium Selenite, quality of the mixed-type feed additive grade sodium selenite can be described more complete and a more complete evaluation system is formed.

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...
