Such proteins could provide more and a better balance of amino acids to cattle, thus improved production. Liquid feed fed to grazing cows should contain by-pass protein when the addition of a natural protein is recommended. It is difficult to compare the energy contents of different liquid supplements. The following feed tag values will assist in making such comparisons. Moisture content .
Water contributes no energy and a liquid feed with less moisture usually has a higher energy value.
Total invert sugar . Sugars are the major source of energy in most liquid feeds. The higher the sugars the higher the TDN from this source. Fat content . Fat contains 2.25 times the energy of sugar or starch.
