HIGH-MOISTURE GROUND EAR C0RN VS. REGULAR GROUND EAR CORN
WITH AND WITHOUT ANTIBIOTICS FOR FATTENING STEERS W.M. Beeson, T.W. Perry and R.E. Honnold Department of Animal Husbandry
Preserving high-moisture ground ear corn (32 percent water) by storing it in an airtight glass-lined silo has introduced a new method of processing corn for cattle feeding. Many times corn is too high in moisture content to be stored safely in a crib without artificial drying. Ensiling offers another process for preserving the ear corn and still retaining its feeding value without spoilage. Often the question has been asked as to whether ensiled ground ear corn with a high-moisture content has less, the same or more feed value per unit of dry matter than regular ground ear corn (17 to 18 percent moisture).
This experiment was designed:
(1)	To determine the relative feeding value of ensiled ground ear corn (32.2 percent moisture) with regular ground ear corn
(17•7 percent moisture), produced from the same fields, for fattening steers.
(2)	To study the effect of an antibiotic (Terramycin) on the fattening of 2 year-old steers fed a high-energy diet.
Experimental Plan
Two-year-old Hereford steers, which had been previously wintered on corn cobs and Supplement MAM and then fed on either pasture or croen chopped forage during the summer, were used for this study. Forty head of steers were divided into 4 lots of 10 steers each and fed on the following daily rations:
