Abstract

This study evaluated the effect of five different periods of antemortem lairage without food on the energy metabolism, gas exchange, mineral and blood acid-base balances of 1174 hybrid barrows, which were divided into six treatment groups according to the lairage period: 130 barrows were considered for the evaluation of the baseline levels (GB); 214 had 0 h of lairage (R0); 228 had 4 h of lairage (R4); 204 had 8 h of lairage (R8); 192 had 12 h of lairage (R12); and 206 had 24 h (R24). In all groups, increasing lairage periods triggered a significant reduction (P < 0.05) in pH, accumulation of lactic acid and percentage of hematocrit. These findings led to the conclusion that antemortem lairage periods longer than 4 h cause hyperglycaemia, hypercalcaemia, hyperlactataemia, hyperkalaemia, hyponatraemia, acidosis, and more severe dehydration in barrows.
