Plastic covered sheds for drying alfalfa

doi:10.11686/cyxb2014335

Abstract

Abstract: Alfalfa (cv. Suntoryin) was dried in clear plastic covered sheds to investigate the benefits for alfalfa hay production in the Huanghuaihai region. Air temperatures in the plastic covered shed were 27-46℃ higher than the outside temperature (5-13℃); there lative humidity under plastic was 16%-52% lower than that outside indicating that plastic covered sheds could increase alfalfa drying rate, helping to maintain forage value while eliminating the risk of high night humidity and rain. The moisture content of alfalfa dried under plastic was reduced to 15% after 32 hours, 48 hours less than the control. The crude protein and total digestible nutrient contents were 18.64% and 66.72%, 20.73% and 11.00% higher than the control, respectively; neutral detergent fiber and acid detergent fiber contents were 41.89% and 29.65%, 12.60% and 17.87% lower than the control, respectively. Alfalfa dried under plastic dried more quickly and was of higher quality suggesting that the use of plastic covered drying sheds would be advantageous for farmers with relatively small areas of alfalfa who live in high rainfall areas.
