# Commission Decision of 14 July 1989 authorizing methods for grading pig carcases in Germany (Only the German text is authentic) (89/471/EEC), Division 3: The lean meat content of carcasses shall be calculated on the basis of 31 variables according to the following formula:

Extent: E+W+S+N.I.

LMP = 63,95382561 – 0,11923455•IP001 – 0,09558979•IP002 – 0,10584604•IP007 – 0,05155666•IP009 – 0,13640649•IP016 – 0,14213204•IP022 + 0,03049588•IP030 + 0,01790568•IP032 + 0,01105555•IP038 – 0,16701099•IP042 – 0,06005469•IP071 – 0,22169624•IP079 + 0,06666878•IP084 + 0,05392766•IP086 – 0,21648737•IP090 – 0,26525617•IP091 – 0,09417923•IP092 – 0,01909767•IP093 – 0,01964313•IP094 – 0,02064380•IP095 – 0,01600385•IP096 – 0,01119575•IP103 – 0,00827959•IP109 – 0,00687431•IP111 – 0,00757384•IP112 + 0,01885055•IP113 + 0,06095365•IP115 + 0,05703606•IP116 + 0,04184455•IP120 + 0,04682307•IP121 + 0,03958671•IP122
where:
LMP = the estimated percentage of lean meat in the carcass,
IP001, IP002, IP007…IP122 are the variables measured by Autofom I.
