    Fatty acid composition, cholesterol and antioxidant status of infrasprinatus muscle, liver and kidney of goats fed blend of Canola oil and palm oil
    (Taylor and Francis, 2016) Adeyemi, K.D.; Sabow, A.B; Ebrahimi, M; Samsuddin, A.A; Sazili, AQ
    The study assessed the lipid profile, cholesterol and antioxidant status of infraspinatus muscle, kidney and liver from goats supplemented with increasing levels of blend of 20% palm oil and 80% canola oil. Twenty-four Boer bucks were randomly assigned to diets containing 0, 4 and 8% oil blend, fed for 100 d and slaughtered. The tissues were subjected to 7 d postmortem storage at 4 C. Diet did not affect total lipid and cholesterol content in the tissues. The proportions of C14:0 in infraspinatus muscle and kidney, and C15:0 in all tissues were lower (p<0.05) while the proportion of C18:3n:3 was greater in supplemented goats than the control goats. Proportion of C18:1n-9 in infraspinatus muscle was higher (p<0.05) in goats fed oil blend than the control goats. The liver and the infraspinatus muscle of the control goats had higher C18:1 trans-10 but lower C18:1 trans-11 compared with those fed other diets. Diet had no effect on catalase, superoxide dismutase and glutathione peroxidase activities, and the concentration of c and d-tocopherol and lipid oxidation in all tissues. The concentrations of a-tocopherol and total carotenoid were greater in the tissues of oil-fed goats compared with the control goats. Regardless of tissue, the catalase and superoxide dismutase activities were stable throughout storage. Lipid oxidative stability, glutathione peroxidase activity, tocopherol and carotenoid contents in the tissues decreased (p<0.05) as postmortem storage progressed. Dietary 20% palm oil and 80% canola oil blend modified the fatty acids in goat meat and offal without compromising their oxidative stability.

    Impact of chill storage on antioxidant status, lipid and protein oxidation, color, drip loss and fatty acids of semimembranosus muscle in goats
    (Taylor and Francis, 2016) Adeyemi, K.D.; Shittu, R. M; Sabow, A.B; Karim, R; Karsani, S.A; Sazili, AQ
    The study examined the effect of refrigerated storage on antioxidant activities, lipid and protein oxidation, fatty acids (FAs), drip loss and color of semimembranosus (SM) muscle from goats. Samples of SM were obtained from carcasses of 15 Boer bucks (7 months old; body weight, 32.18 ± 0.81 kg) subjected to an 8 d storage at 4°C. Superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPX) activities were stable while carotenoid, tocopherol, water holding capacity and redness declined (P < 0.05) as storage progressed. Carbonyl content increased from 1.85 to 4.73 nmol/mg protein while thiol content reduced from 54.22 to 42.82 nmol/mg protein. The TBARS value increased from 0.2 to 0.8 mg MDA/kg. SDS-PAGE expression of myosin heavy chain (MHC) decreased (P < 0.05) from 72.45 to 49.82 density/mm2 while actin reduced (P > 0.05) from 14.00 to 13.08 density/mm2. The concentrations of n-3 and n-6 FA decreased while the saturated FA increased over storage. Correlations (P < 0.05) were found between antioxidant vitamins and quality indicators of chevon.
