—LancdSter Farming,.Satiirday, June 5, 1976 58 Horse breeding problems eased KALAMAZOO, Mich - Horse breeding management has entered a new technological age with the introduction of the first agricultural prostaglandin product in the United States. Announced at a Prostaglandins in Agriculture Conference held hear here in March by The Upjohn Company, the in troduction of Prostin F 2 alpha represents a major breakthrough in phar maceutical technology. This prostaglandin product will be used by veterinarians to aid horse breeders in the timing of estrus and breeding management problems. According to Upjohn researcher Dr. James Lauderdale, Prostin F 2 alpha (PGF2a) influences the time of estrus in cycling mares. This action aids in bringing most difficult-to breed mares into estrus, and also helps control timing of estrus in normally cycling mares for more efficient breeding. Prostaglandins are potent substances believed to play a hey role in cellular metabolism and regulation of many bodily functions. They have attracted world wide interest during recent years because of the Widespread effects different prostaglandins have on various body processes in both humans and animals. Prostaglandins regulate a variety of bodily functions including reproduction, blood pressure, gastric secretion, inflammatory response to injury, hormone action, and blood dotting. Some researchers term them the new “miracle drugs” of the 1970’s and 80’s. Upjohn has been a worldwide leader in research and development of prostaglandin compounds, and last year introduced PGF2a into some in ternational markets for regulating estrous cycles in both horses and cattle. “Introducing of Prostin F 2 alpha in the United States represents Upjohn’s first step in developing these very significant compounds for use in what’s hoped to be a wide range of animal health applications,” adds Dr. Robert Zimbelman, Upjohn research manager. Mares are regarded as one Resource Recovery Many communities are find ing that it pays to reclaim resources from their gar bage for recycling Current ly, garbage-to-energy sys tems are operating in more than a half-dozen cities Another fifty communities are building or planning such facilities, Resource recovery systems that mag netically reclaim only fer rous metals - mainly steel cans - are operating in thirty communities The cans are detmned, remelted into new steel, used m a chemical leaching process to recover copper from low grade ore and used in the production of ferroalloys TRY A CLASSIFIED AD! of the most difficult animals to breed efficiently because of the seasonal nature and relatively variable length of their estrous cycles. Ac cording to Dr. John Sullivan, American Breeders Service, the great variability in the normal reproductive per formance of mares is a major breeding problem.
