' FDA application for feeding MGA, Rumensin submitted KALAMAZOO, Mich. - Several years of research has culminated in the recent filing of a new animal drug application with the FDA for combination use of MGA and Rumensin in feedlot heifers. The application submitted by TUCO, makers of MGA and a Division of The Upjohn Company, evaluated the efficacy, feed stability, tissue residue and safety of using these two drugs in combination. The trials were conducted by TUCO in cooperation with Elanco Products Company, manufacturers of Rumensin, at Colorado State University and West Texas State University, and at feedlots in J’wa, Michigan and Min nesota. According to FDA requirements, efficacy studies compared the per formance of feedlot heifers receiving the MGA/Rumensin com- “But even more im bmation to the performance pressive is that the value of of heifers fed each feed your state’s exports since additive singly.

Tissue residue “This year alone we have committed over $22.1 million to agricultural export promotion, nearly double the funds committed prior to 1977,” Bergland said. He also pointed out seven new world trade promotion offices have been opened in the last two years and that new export credit programs are being implemented. “Total U.S. farm exports this year will be 25 percent greater than the record $32 billion exported last fiscal year and represent a 75 percent growth since 1976. This will generate an agricultural trade surplus of $22.5 billion this year. “ The tremendous domestic and foreign demand prospects for our - \£.«V*> ~* ,'.n^sSS*^"V were used to establish the proper drug withdrawal time prior to slaughter to assure consumers that marketed meat is safe from any drug contamination.
