How to calculate metabolizable energy in feed
WebFeed evaluation systems to assess the energy value of a feed can be based on DE (TDN system), ME (ARC, 1980) or sometimes NE (NRC, 1984). Energy is digested in the rumen, in the small intestine (energy containing proteins) and in the large intestine and absorbed from the gastro-intestinal tract. However, a part of the Web18 sep. 2007 · A biological assay for metabolizable energy in poultry feed ingredients together with findings which demonstrate some of the problems associated with the …
