Bedding materials have a significant impact on heat conductivity loss between organism and environment. The type of bedding materials can reduce in different levels the loss of heat conductivity. We are going to study the impact of bedding material on heat conductivity loss of piglets when they are kept directly on concrete surfaces, wood, plastic layers. Conductivity coefficients (λ) were 1.1 for concrete, 0.125 for wood, and 0.250 for plastic materials. In addition, this study evaluates the importance of thickness of bedding materials on heat conductivity loss of pigs. The heat loss by conductivity on growing pigs was reduced respectively: 34% when pigs were kept in wooden materials, 59% in plastic materials. The thickness of bedding material was 25 cm and the temperature was 19 o C for all types of materials used. These findings are of significant importance to pig's industry husbandry.
