This study was carried out in the sheep field of the Department of Animal Production / College of Agriculture - Tikrit University for a period from 25/10/2021 to 2/1/2022 (70 days), preceded by a 14-day preliminary period to acclimatize the lamb to concentrated feed. In the sixteenth month, Awassi lambs aged 4-5 months were used from local trade, the initial weight was adjusted (25.350 ± 2.25) kg, the experiment was divided into two periods (0-35 days, 36-70 days) respectively . Study The results of this study are as follows: There are significant differences in efficiency for the second, third fourth and treatments (P≤0.05) on the first treatment. food conversion. It was in those qualities. Adding a mixture of (Cr-Met and Zn-Met) led to a significant (P≤0.05) increase in insulin concentration over the rest of the treatments, while the first treatment recorded a significant (P≤0.05) increase in cortisol concentration in lambs’ blood over the rest of the treatments. Significantly (P≤0.05) the two treatments (T2 and T3) over the rest of the treatments in the concentration of thyroxine (TSH), and the addition of Cr-Met recorded a significant increase (P≤0.05) over the rest of the treatments in the concentration of thyroxine (T4). It was noticed a significant decrease (P≤0.05) in the treatments (T2, T3, T4) compared to the control treatment (T1) in the concentration of threonine (T3). The length of the treatment period and the interaction between the periods and the treatments had a significant effect on these characteristics.

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.
