exploratory study on the relationship between age, reproductive stage, body condition score, and liver biochemical profiles in rembi breed ewes

Background: the rembi sheep breed is renowned for its exceptional meat quality and significant economic profit. nevertheless, there is a gap in research on the hepatic parameters of this breed in algeria despite the considerable value of the liver in the algerian population’s diet.   objectives: the research aimed to determine the impact of physiological factors (age, physiological stage, and body condition score) on biochemical sheep liver parameters. methods: sixty clinically healthy female rembi breed sheep, aged between 3 months and 7 years, raised at the technical institute of livestock (itelv) ksar chellala farm in tiaret province, algeria, were selected for biochemical analysis and assessing aspartate aminotransferase (ast), alanine aminotransferase (alt), gamma-glutamyl transferase (ggt), alkaline phosphatase (alp), total bilirubin (tbil), direct bilirubin (dbil), albumin (alb), and total protein (tp).results: the concentrations of ast, alp, and ggt increased significantly (p≤0.001) in young sheep, while alt and tp levels decreased (p≤0.05). however, a high level of ggt (p<0.001) was also observed in lactating ewes, and during pregnancy, females have a low level of alp (p<0.001). furthermore, the body condition score does not affect any of the measurements.conclusion: considering the animal’s age and physiological stage is critical before interpreting the results.
