Continuing demands of stockmen and feed dealers for improved methods of handling hay have stimulated interest in hay pelleting and wafering machines. Handling problems in California are further complicated by the need to transport hay long distances from areas of production to consumption. Pelleting or wafering is intended to package hay in a dense, free-flowing form that can be handled, transported, and stored in bulk. Pelleted hay (made from ground hay) has the best density and handling characteristics, but lacks the coarse roughage considered necessary for dairy cows. Watered hay (produced without grinding) contains sufficient roughage to overcome this objection.
