abstract
The influence of the flooring pattern on the thermal comfort of Large White Yorkshire weaned pigs was investigated in three different flooring systems. Three different flooring systems in conventional pig farming viz., solid concrete floor (T₁), raised slatted concrete floor (T₂) and raised slatted polypropylene floor (T₃) formed the experimental housing design and three sty of equal sizes measuring 3.50 m x 2.90 m were taken. Pigs in the different housing systems are maintained in standard floor space of 0.8-1.0 m² with similar feeding practices and management conditions. Under each treatment, 10 numbers (5 males and 5 females in each treatment) of weaned large white Yorkshire pigs are allotted with average body weight of 16.50±0.50 kg respectively. Microclimatic variables include air temperature, relative humidity, air velocity were recorded daily and statistically there was significantly (P<0.01) higher difference observed between the treatment groups in the morning and afternoon hour recording.
