17-Ethyl-19-Nortestosterone and 6 Methyl-17 Acetoxy-6-Progesterone in Growing-Finishing Swine Rations
A. H. Mimeo Series 63-08
Previous research at this station showed that 17-ethyl -19-nortestosteronte (Nilevar) significantly increased growth of female rats, but did not increase the growth of uncastrated male rats. When this hormone-like compound was fed to swine; two treatment levels increased the rate of gain of female growing-finishing pigs. Rate of gain of castrated male pigs was not improved by low levels of the compound and higher levels depressed growth. SD10363 (6 methyl-17 acetoxy-6-progesterone) is a hormone-like compound which has the possibilities as a good additive for growth stimulation in swine. The purpose of this experiment was to evaluate these compounds in swine rations.
