Effect Of Stress in Some Blood Parameters and Heat Shock Protein 70 Of Awassi Syrian Lambs
This study aimed to look into the impact of road transportation in the dry, hot region of Erbil-Kurdistan, Iraq, on blood parameter changes and heat-shock protein 70 (HSP70) expressions in lambs as welfare indicators. A total of thirty Awassi Syrian sheep 1-year-old lambs with an average live weight of 63.894±0.48kg were subjected to three pre-slaughter handling groups of ten (10) animals each one day before transportation. The first group was kept under normal farm conditions and used as a control (T1). The other two groups were loaded into an open truck and driven for 2 hours before being unloaded and then lairage for 0h (T2) 12h (T3). According to the findings, the response of biochemical parameters and heat-shock protein in kidney and liver tissues rose significantly. Cortisol, adrenaline, noradrenaline, glucose, and lactate levels were considerably higher in T2 than in T1 and T3 lambs. According to heat shock protein 70 expressions, transit without shade was more stressful for the lambs. Therefore, it is necessary to use an appropriate resting time following road transportation pre-slaughter to prevent welfare problems.
