Extract

Concentrate ingredients for ruminants are valued with the help feeding tables, based on chemical composition, the Tilley and Terry technique and nylon bag incubations. However, tables only give averages, which cannot be used for individual lots, and the nylon bag technique is expensive, time consuming and accuracy may be low. The aim of this research was to investigate the possibilities to obtain feed characteristics of a broad range of concentrate ingredients with the gas production technique (Cone et al., 1996).
