Physiological profiles of Zebu steers during transport and pre-slaughter
Background: pre-slaughter handling causes stress in cattle that may alter numerous physiological variables. Objective: to determine whether in-farm handling of steers, road transport by truck, or slaughterhouse lairage affect blood stress indicators. Methods: a total of 65 castrated Zebu steers were...

| description | Background: pre-slaughter handling causes stress in cattle that may alter numerous physiological variables. Objective: to determine whether in-farm handling of steers, road transport by truck, or slaughterhouse lairage affect blood stress indicators. Methods: a total of 65 castrated Zebu steers were randomly selected and transported during 4 h in the same truck, under similar handling conditions. Blood samples were taken by jugular or coccygeal venipuncture at the farm, at the slaughterhouse, and during exsanguination to measure plasma cortisol, glucose, lactate, creatine kinase (CK), ß-hydroxybutyrate (ßHB), creatinine, total protein, urea, packed cell volume (PCV) values, white blood cells (WBC) and neutrophil:lymphocytes ratio (N/L). Results: pre-slaughter handling did not have a negative influence on protein metabolism nor did it cause dehydration. ß-hydroxybutyrate and lactate values did not change (p>0.05). Transportation increased cortisol, glucose, creatine kinase concentrations and N/L ratio (p<0.05). Conclusion: pre-slaughter was a stress-generating event that moderately affected animal welfare and increased physiological variables within a range considered normal for steers. |
