نبذة مختصرة : The aim of this paper it is to help quantifying the forage consumption in Chinchilla farms function of breeding system. The two breeding systems adopted worldwide by the breeding farms, are on wire netting floor and bedded cages. All data’s we found in literature about forage standards for this species, it’s too old, (1981, 1982, 1986), and the new data’s quoting the oldies, without making a laboriously experiment subject. In this order we consider opportune to bringing up them to date. In this way, at the wire netting floor system we pursue the roughage (grass-clover hay) and the complete mixed pelleted forage consumption, collecting the rests bellow the cages, separated them in parts, and calculate the difference. At the bedded system we weight the rests every day, ad the difference were considered the consumption. After drawing and processing data’s we obtained a bigger pellet consumption at the adult animals kept on wire net floor with 48.66% comparing to the bedded cages system. In a case of youths the situation is exactly inverse, the weaned animals kept in bedded cages had bigger pellet consumption with 28.93% compared to the wire net floor system.
