Abstract
The National Fertilizer and Feed Inspection Station assumes responsibility for the development of methods for animal feed analysis in Japan. The methods are recommended for adoption as official methods in Japan to be used by the National Fertilizer and Feed Inspection Station and other laboratories in the analysis of commercial feeds. Every effort is made to ensure that the results obtained are of a high quality by evaluating and validating the methods and through having a quality control system in place. Our standard method development manual requires several stages be followed in the development of a new method. These include inhouse validation of the method, a collaborative study and evaluation by a committee. Quality control is achieved by routinely participating in laboratory proficiency tests and by ensuring that laboratory equipment is maintained to a high standard.
