Extract

Inclusion of fishmeal in diets fed to dairy cows has been found to increase milk yield and milk protein content (Pike et al 1994). This is thought to be the result of increased intake of DUP. However, its inclusion in dairy rations is limited by its relatively high cost in addition to the negative image of feeding protein derived from animal sources in the light of the recent BSE crisis. The literature contains many instances where no response has been found to increasing DUP supply by feeding protected vegetable protein. The lack of response could be attributed to an unbalanced amino acid composition of DUP (Schingoethe 1996). This study was designed to observe the effects of replacing a proportion of cereal with either fish meal or a protected protein blend (Amino Green™, Nutec Ltd, Lichfield) formulated to supply the ideal balance of amino acids for milk production in a high yielding dairy cow.
