Excerpts from the report Summary: Bruising, crippling, and killing of animals transported to market by rail and motortruck constitute a heavy annual loss to the Nation's livestock industry. The rates of loss established in this study of Farmer Cooperative Service, applied to total animals slaughtered in 1955 and 1956, indicate that the national loss in these years for dead and crippled animals alone approximated $8 million a year at average annual prices. Because of the extent of these losses, farmers and their cooperatives as well as other segments of the livestock industry, are deeply concerned in seeing that all feasible steps are taken toward reducing them. For this reason Farmer' Cooperative Service made this study to analyze factors contributing to loss in transit. Particularly, it has studied the relationship of length-of-haul and seasonal weather conditions to losses in livestock received at 10 major markets in 1954-55.
