The antioxidant activity of the enzymes during post mortem processes can be influenced by pre-slaughter treatments as observed in
this study. Our data showed the highest concentration of GSH in the meat from goats supplemented with MOL than SC and GH. The
increased levels of GSH indicate the protective role of Moringa
leaves in the mammalian cells viathe maintenance of thiol-redox
status and detoxification of exogenous and endogenous reactive
molecules (Oyedemi, Bradley, & Afolayan, 2010). GSH is a tripeptide
(γ-glutamylcysteinylglycine) and a most abundant non-protein antioxidant in the cells, plays a vital role in the defence against oxidative
stress-induced cell injury and mitochondria damage. It is also believe
to scavenge ROS directly or act as a substrate for other antioxidative
or repair enzymes (Akerboom & Sies, 1981). GSH plays a central
protective role against the damaging effects of bacteria, viruses, pollutants and free radicals (Gutman, 2010). Our data in the present
study concurred with the findings ofKumar and Pari (2003)who
reported a protective role of MOL in a rat model
