De bepaling van TAN-excretie op varkens-, pluimvee- en melkveebedrijven = Quantification of TAN excretion in pig, poultry and dairy farms

The ammonia emission from farm animals is largely determined by the excretion of total ammoniacal nitrogen (TAN) in the urine. In this report the on-farm collection of data required to calculate TAN excretion on pig, poultry, and dairy farms is addressed.
