Diferentes tipos de pisos no comportamento de leitões em fase de creche.

Abstract

The objective of this research was to raise the temperature of the contact surface using two types of floors and to evaluate the thermal comfort of nursery piglets. The research was carried out in the experimental area of pig farms at Campus III of the Federal University of Paraíba, Bananeiras - PB, between September and October 2016. Twenty - four piglets were weaned with a mean age of 21 days distributed in 8 bays according to with the treatments associated to the floors, being Treatment 1: EVA Plates + Leaked Plastic Floor (Floor 1) and Treatment 2: Leaked Plastic Floor (Floor 2). The characterization of the thermal environment of the nursery was performed by recording the air temperature (Tar), relative humidity (UR), black globe temperature (Tgn), lightness and wind speed (VV) Index of Black Globe Temperature and Humidity (ITGU) and Thermal Charge of Radiation (CTR). Thermal comfort indexes, superficial thermal mapping (floors and piglets), the behavioral frequencies of the animals and the productive performance of the animals were used for the thermal comfort of the floors. The experimental design was completely randomized (DIC) with two treatments and four replications, comparing the means by Tukey's test (P <0.05). The results indicated that, from the thermal point of view, Floor 1 provided greater thermal comfort with reflexes in the lower incidence of agonistic behavior of the piglets.
