Pork producers have witnessed a drop of price amounting to around $15 in the futures market for lean hogs within the last couple of months.  Agricultural economist, Dr. Steve Meyer with Partners for Production Agriculture believes lean hog futures may continue to see wide price swings in the coming months.  Meyer spoke at the South Dakota State University Swine Day seminar on Tuesday and says the action on the futures exchange markets is likely to continue.  Meyer says high input costs with feed and fuel are not going away, and he says it may be difficult to secure profits.
