“…Ekiz et al (2012a) did not observe significant differences in the haematological parameters of lambs after 75 min of transport in comparison with a base level. Bórnez et al (2009) also reported an absence of significant variations in RBC, HCT and HGB values in 30-day-old and 70-day-old lambs after 30 min of transport.…”

“…Ekiz et al (2012b) did not report significant correlations between the N : L ratio in lambs and age at weaning. In another study, these authors (Ekiz et al, 2012a) noted a significant increase in the N : L ratio in 135-day-old rams after 75 min of transport to the slaughterhouse. In our study, pre-slaughter handling was also stressful, but the values of the N : L ratio and its increase in successive stages of pre-slaughter handling were lower in EG than in CG lambs.…”

“…Increased blood cortisol levels in lambs after 75 min (Ekiz et al, 2012a), 2 h (Ali et al, 2006) and 48 h of transport (Tadich et al, 2009) indicate that transport is the most significant stressor during pre-slaughter handling.…”

“…Lambs exposed to the high intensive handling regime in the present study still had high ultimate pH levels after a 14-h rest period, suggesting that these animals had not completely recovered from the stress caused by handling before slaughter. Ekiz et al (2012) found that an 18-h lairage period was sufficient to reduce the effect of transport on ultimate pH. Therefore, animals exposed to transport and intensive handling may require longer in lairage to recover.…”

“…In the present study, cortisol concentrations at slaughter were still higher in LOW and HIGH lambs than baseline values. In addition, Ekiz et al (2012) found that cortisol concentrations of lambs after a 30 min or 18 h lairage period were still evaluated compared with baseline values. However, Liste et al (2011) found that lambs given a 12-h lairage period had lower cortisol concentrations than non-rested animals.…”

Before slaughter, lambs may experience several stressors such as feed and water deprivation, handling and transport that have the potential to negatively impact welfare and meat quality. The objective of this study was to evaluate the effect of pre-slaughter handling, exercise and the presence of a dog on the behaviour and physiology of lambs and meat quality at slaughter. At 6 months of age, 60 lambs ( n = 20 lambs/replicate; three replicates) were allocated to one of the two treatment groups ( n = 30 lambs/ treatment): low (LOW) intensive handling or high (HIGH) intensive handling. LOW lambs were moved short distances, quietly and without the use of a dog before transport. HIGH lambs were moved quickly, long distances and with a dog present before transport. Lamb behaviour (standing, lying, rumination and panting) was recorded for 1 h before (post-treatment) and after transport (post-transport), and for 30 min before slaughter (pre-slaughter). Blood samples were collected before (baseline), after transport (post-transport) and at exsanguination (at slaughter) to assess cortisol, lactate and non-esterified fatty acid (NEFA) concentrations. At slaughter, lamb carcases ( M. longissimus lumborum) were evaluated for pH levels, drip and cook loss, and tenderness. HIGH lambs spent more time standing ( P < 0.001) and panting ( P < 0.001) and less time lying ( P < 0.001) and ruminating ( P < 0.001) post-treatment than LOW lambs, but more ( P < 0.001) time ruminating post-transport. All lambs spent more time standing ( P < 0.001) and less time lying ( P < 0.001) and panting ( P < 0.001) post-transport and pre-slaughter than post-treatment. Cortisol concentrations were greater ( P < 0.001) in lambs post-transport and at slaughter compared with baseline values. Lactate concentrations were lower ( P = 0.002) in HIGH than LOW lambs. In addition, NEFA concentrations were higher ( P < 0.001) post-transport and at slaughter in HIGH compared with LOW lambs. Ultimate pH was higher ( P < 0.001) in HIGH than LOW lambs and pH declined quicker ( P = 0.012) in LOW than HIGH lambs. Cook loss, drip loss and shear force were lower ( P ⩽ 0.05) in HIGH than LOW lambs. The HIGH intensive pre-slaughter handling regime used in the present study caused stress in lambs and increased ultimate pH that could potentially negatively impact welfare, product quality and consistency.
