摘要: Abstract Two studies were conducted to determine the effects of floor or bedding type on lamb performance, carcass characteristics, and visceral organ mass. In Exp. 1, seventy-two early weaned Targhee × Hampshire ram lambs (initial BW = 35.2 kg) used in a randomized complete block design experiment with fed an 80% concentrate diet. The types flooring investigated expanded metal, dirt sand top-dress, straw bedding. Flooring affected DMI (P
