Abstract

In any feeding operation considerable attention should be given to the selection of a proper ration. A ration that will produce the most rapid gain will not necessarily produce the most economical gain. Rate of gain and fattening depend on the intake of digestible energy in excess of maintenance when the ration contains adequate amounts of other essential nutrients. Since many feed additives have become available in recent years, it is important to know their effects with various types of rations. Diethylstillbestrol have been reported to consistently improve gain and feed efficiency. Other feed additives have not been investigated as extensively as diethylstilbestrol, and only limited work has been reported concerning the value of various feed additives when fed with different types of rations. Diethylstillbestrol, diallydiethylstillbestrol, tetra-alkylammonium stearate (dynafac) and an enzyme preparation (Agrozyme) were tested to determine the response to these compunds when feeding rations containing various levels of energy.
