Livestock

Production system based livestock representation has been recently developed in colaboration with the team of Mario Herrero from the International Livestock Research Institute (ILRI). The model differentiates between 14 production systems consistent with the ILRI/FAO production system classification.

RUMINANT

Input-output-parameters for ruminants are etimated through the RUMINANT model (Herrero et al., 2008)¹. It is a dynamic simulation model of digestion in ruminants largely based on IPCC methods. It predicts intake, production (meat and milk), and excretion as well as metabolism end products (methane, volatile fatty acids, etc...).
