Utilização de embalagens Tetra Pak® como isolante térmico no revestimento de escamoteadores para leitões

Abstract

Two experiments were conducted in laboratory and field conditions to evaluate the thermal efficiency of the Tetra Pak packaging as insulation in heated creeps. In the laboratory experiment a completely randomized design was used, adopting two treatments (with and without packaging coating with Tetra Pak®) with 15 repetitions (days). The experiment under field conditions was conducted in a swine nursery. The design was completely randomized, adopting two treatments with 12 repetitions. The treatments consisted of heated creep with and without Tetra Pak® lining. The data measured were ambient temperature, relative humidity, surface temperature of the floor, surface temperature of skin, behavior and weight gain of suckling piglets. The use of Tetra Pak® packaging as insulation in creep coating maintained the ambient temperature comfortable (32 °C), providing thermal comfort to suckling piglets.
