Metabolizable energy (ME) energy is used to denote the energy value of feed for poultry. ME can be expressed as values ​​of apparent metabolizable energy (AME). AME is used to determine the exchange energy food for birds. Vietnam Nehring methods used to estimate the AME value of the raw material fed to chickens. This method is usually the error is large and ...
