There is increasing interest in the Cornell Net Carbohydrate and Protein System (CNCPS) (Russell et al 1992, Sniffen et al, 1992) for rationing dairy cows, but its use in the UK has been limited because the raw material database was based on North American feedstuffs. The database contained no information on grass silage, and the values for feeds such as maize silage and brewers grains may not be representative of those in the UK. This work was carried out to establish a UK database of forages and raw materials for the CNCPS model.
