A.S. Series 71-17
One hundred thirty-six steer calves averaging 440 lb. were used in a 56-day trial to study the value of supplementing drought-damaged corn silage with protein and energy. The silage contained only about 8 bushels of grain per acre and was harvested in mid-August at 30% dry matter. It was stored in a 71-ton stack, covered with a plastic cover and sealed with earth around the bottom. The stack was opened with a plastic cover and sealed with earth around the bottom. The nitrogen (dry basis) were 11.7 and 0.24 at ensiling. The four treatments (34 steers each) were 1 or 2 lb. of supplement (32% protein) per head daily each with 2 levels of corn grain. The supplements supplied 350 mg. each of chlortetracycline and sulfamethazine and 30,000 I.U. vitamin A per steer daily.
