Purdue University Agricultural Experiment Station Lafayette, Indiana Mimeo A.H. 204 April 26, 1957 "DYNAFAC" AND TORULA YEAST AS ADDITIVES TO HIGH - AND LOW-MOISTURE GROUND EAR CORN FOR FATTENING HEIFERS Wo Mo Beeson, T. W. Perry and R. E# Honnold Previous research at Purdue (Mimeo AH-169) has indicated that high-moisture ground ear corn (32 percent water) can be ensiled in a glass-lined silo and preserved for cattle feeding without loss of feeding value. In our first experiment (1956), steers fed on the high-moisture ground ear corn required 12 to 15 percent less com to produce a pound of gain than those fed regular ground ear corn (17-18 percent moisture). Many times corn is too high in moisture content to be stored safely in a crib without artificial drying. Ensiling offers another method for preserving ear corn to retain its feeding value. This experiment was designed to compare the feeding value of high- and low-moisture corn for fattening heifers when fed with and without "Dynafac" and Torula yeast, "Dynafac" is a trade name used to describe a product containing 20 percent of tetra alkylammonium stearate, or sometimes referred to as trimethyl-a Ikylammonium stearate, and 80 percent bonemeal, "Dynafac" is a highly insoluble compound that possesses certain bactericidal properties. We are' testing this product to determine if it will stimulate gain and improve feed efficiency when incorporated in fattening rations for heifers. Each heifer was fed 1 gram of "Dynafac" daily which is equivalent to 200 mg. of tetra: alkylammonium stearate. Torula yeast is a primary grown yeast processed from selected wood sugars. Sometimes it is commonly called wood yeast. Feed lot tests at the Iowa State College have indicated that under certain feeding conditions, Torula yeast will improve gains and feed efficiency in cattle. Previous research at Purdue has shown that two other types of yeast—namely, dried brewer?s yeast and active cell yeast—had no consistent beneficial effects on cattle in rations balanced with "Supplement A." This test was devised then to see if Torula yeast would be of any benefit as an addition to "Supplement Au with either high- or low-moisture corn. Six lots of 12 heifer calves each were fed from December 6, 1956, to April 11, 1957, 126 days, on the following rations: Lots I, II and III were full-fed on high- moisture ground ear corn, 3.0 lb. Supplement A, hay and minerals; and Lots IV, V, and VI were full-fed on regular ground ear corn, 3.0 lb. Supplement A, hay and minerals. The treatments were as follows: Experimental Plan High-Moisture Ground Ear Corn (32.5$ water) Regular Ground Ear Corn (15.5$ water)
