| Popis: | Objective: This study was conducted to evaluate the physicochemical properties and changes in moisture concentrations of bedding materials under the conditions of rearing Korean Hanwoo cows.Methods: Two experiments were conducted to investigate the physicochemical characteristics (Exp. I) and usefulness as beddings for rearing cattle (Exp. II) by the type of beddings such as sawdust (SD), wood shavings (WS) and sawdust+wood shavings (S+W; 1:1 in volume), and the species of pine trees from different countries of origins (China, Pinus armandii, AR; Vietnam, Pinus kesiya, KE; USA, Pinus rigida, RI).Results: In Exp. I, SD-AR showed the largest proportion (78.3%) of fine particles (250 μm+ below 250 μm) and the highest bulk density (208 kg/m3) among treatments (p2) of ammonia emissions were the lowest (p |
