As has been illustrated, ourfeedinc: standards are theguides which show us whatthe average animal requiresin order to give the best re-sults without anv illustrate balancing a ration by an example, letus assume that we want to feed, according to theHaecker feeding standards, a balanced ration to a dairycow weighing 1000 lbs. and producing 20 lbs. of 4%milk, per day. According to the Haecker feeding standard, the follow-ing nutrients will be required, and the nutritive ratioof these, as given below is 1 .& .iiMii^- A GOOD SILO feedi:n^g aximals 227 .Nutrients Required Use Protein Carbo-hydrates Fat For maintenance 1000 lb. cow lbs. . lbs.
