“…M. oleifera leaves are reported to contain substantial amounts of nutrients such as protein, fiber, carotenoids, and tocopherols ( Jongrungruangchok et al, 2010;Moyo et al, 2011Moyo et al, , 2012Saini et al, 2014a, b); vitamins as A, C, and E (Hekmat et al, 2015); and minerals as potassium, calcium, sodium, magnesium, iron, copper, zinc, selenium, and manganese (Hekmat et al, 2015;Al-Mufarji and Mohammed, 2022a, b). The M. oleifera contains betacarotene and other phytochemicals known for their antioxidant abilities (quercetin, kaempferol, rutin, and caffeoylquinic acids), antioxidant vitamins (A, C, and E), and antioxidant minerals (zinc and selenium) which can play important roles as anti-stress ( Jaiswal et al, 2009;Vongsak et al, 2014;Afzal et al, 2021). The current study aims to evaluate the modulatory influences of M. oleifera at rates of 50 and 100 g on thermo-tolerance parameters, blood, and metabolic status of ewes before subjecting to heat stress in arid subtropical areas.…”
