The objective of this paper was to evaluate oxidative stress during different pregnancy stages in Lohi sheep reared in Libya.
Investigations were carried out on Lohi sheep between 1.5 and 5 years of age. A total of 40 sheep were sub-grouped into various
stages of pregnancy along with non-pregnant controls as follows: non-pregnant (n=10), early pregnancy (n=10), mid pregnancy
(n=10), and late pregnancy (n=10). Blood samples were collected from pregnant sheep and preserved at -20°C and further used
for evaluating the concentrations of total antioxidant status (TAS), total oxidant status (TOS), malondialdehyde (MDA),
superoxide dismutase (SOD), catalase (CAT), and paraoxonase (PON-1). In pregnant sheep, TAS, TOS, MDA, SOD, CAT, and PON-1
values were significantly (P &lt; 0.05) different. TOS and MDA increased from non-pregnant ewes to early, mid and late stages of
pregnancy whereas TAS, SOD, CAT, and PON-1 significantly (P &lt; 0.05) decreased with the progression of pregnancy. The study
suggests that the use of oxidant and antioxidant markers along with the blood metabolic profile should be the recommended
procedure for monitoring health status during pregnancy to evade reduced productive performance and economic losses. </dc:description>

Cilj rada je bio da se ispita oksidativni stres tokom različitih stadijuma bremenitosti kod ovaca rase Lohi u Libiji. Ispitivanja su sprovedena na ovcama starosti između 1,5 i 5 godina. Ukupno 40 ovaca je grupisano na osnovu različitih stadijuma bremenitosti, zajedno sa kontrolnom grupom, koju čine ovce koje nisu bremenite. Grupe su činile nebremenite ovce (n = 10), ovce u ranoj bremenitosti (n = 10), ovce u srednjoj bremenitosti (n = 10) i ovce u kasnom stadijumu bremenitosti (n = 10). Uzorci krvi su prikupljeni od svih ovaca, konzervisani na -20°C i dalje korišćeni za procenu koncentracije ukupnog antioksidativnog statusa (TAS), ukupnog oksidativnog statusa (TOS), malondialdehida (MDA), superoksid-dismutaze (SOD), katalaze (CAT) i paraoksonaza (PON-1). U TAS, TOS, MDA, SOD, CAT i PON-1 kod bremenitih ovaca zabeležene su statistički značajne (P &lt; 0,05) razlike u dobijenim rezultatima. Koncentracije TOS i MDA su se povećavale od negravidnih ovaca do ovaca u ranoj, srednjoj i kasnoj fazi bremenitosti, dok su TAS, SOD, CAT i PON-1 zabeležili značajan pad (P &lt; 0,05) sa odmicanjem gravidnosti. Može se zaključiti da upotreba oksidanasa i antioksidanasa kao markera zajedno sa metaboličkim profilom u krvi treba da se koristi kao preporučeni postupak za praćenje zdravstvenog stanja tokom perioda bremenitosti kako bi se izbeglo smanjenje proizvodnih performansi i ekonomski gubici.</dc:description>
