Abstract
The effects of shearing on behavioral patterns, antioxidants, and inflammatory and stress
biomarkers was investigated in Ossimi sheep. Clinical parameters and behavioral patterns
were recorded, and serum samples were collected pre-shearing and 1, 5, 10 and 15 days
post-shearing from 60 Ossimi sheep. The results revealed that grooming and standing idle
frequencies were significantly (
P
<0.01) increased post-shearing. There
were significant (
P
<0.01) increases in IL-6, cortisol, and MDA
detected from the 1st to the 10th day post-shearing compared to pre-shearing values. IL-2
and TNF-α significantly (
P
<0.01) increased from the 1st until the 5th
day post-shearing compared to pre-shearing values, while significant
(
P
<0.01) decreases in the values of catalase from the 1st until the
5th day post-shearing compared to pre-shearing values were recorded. Regarding to
glutathione reductase, there was a significant (
P
<0.01) decrease from
the 1st until the 10th day post-shearing compared to pre-shearing values. Shearing leads
to significant changes in antioxidants, inflammatory, stress biomarkers, and some
behaviors in sheep.
