    Carcass characteristics and meat quality assessment in different quail lines fed on canola seed supplemented diets
    (Indian Journal of Animal Sciences, 2020) Behnan Sabow, Azad; Saber Haddad, Hurea; Nakyinsige, Khadijah
    The effect of dietary supplementation with canola seed on carcass and meat quality characteristics in three quail lines was studied. Ninety quails aged 4-weeks were selected from three lines (white, black and brown) and randomly allocated to 3 feeding groups. One group was fed a basal diet as control, while the other two groups were fed on basal diet with 1 or 3% canola seed supplementation. Quails were slaughtered at 10 weeks of age. At 24 h postmortem, breast and thigh meat samples were separated; vacuum packaged and stored at –40°C until meat quality analyses. Results showed that carcass characteristics did not differ (P>0.05) between dietary treatments. However, the inclusion of canola seed increased (P<0.05) the concentration of total omega-3 fatty acid in meat and decreased widely the omega-6: omega-3 ratio compared to the control diet. Feeding 3% canola seeds decreased the level of malondialdehyde (MDA) in the breast and thigh muscles of quails at day 5 of post-mortem. Regardless of dietary treatments, no carcass and meat quality characteristics except carcass weight differed between 3 quail lines. Brown quails exhibited significantly higher (P<0.05) carcass weight than white and black ones. These results indicate that feeding canola seed might modify meat fatty acid profile with better shelf life during postmortem aging. Likewise, due to high carcass weight, brown quail lines may be preferred for meat production purposes.

    Changes of microbial spoilage, lipid-protein oxidation and physicochemical properties during post mortem refrigerated storage of goat meat
    (Animal Science Journal, 2016) Behnan Sabow, Azad; Behnan Sabow, Azad; Qurni Sazili, Awis; Aghwan, Zeiad Amjad; Zulkifli, Idrus; Meng Goh, Yong; Abidin Ab Kadir, Mohd Zainal; Nakyinsige, Khadijah; Kaka, Ubedullah; Dauda Adeyemi, Kazeem
    Examined was the effect of post mortem refrigerated storage onmicrobial spoilage, lipid-protein oxidation and physicochemical traits of goat meat. Seven Boer bucks were slaughtered, eviscerated and aged for 24 h. The Longissimus lumborum (LL) and Semitendinosus (ST)muscleswere excised and subjected to 13 days post mortem refrigerated storage. The pH, lipid and protein oxidation, tenderness, color and drip loss were determined in LL while microbiological analysis was performed on ST. Bacterial counts generally increased with increasing aging time and the limit for fresh meat was reached at day 14 post mortem. Significant differences were observed in malondialdehyde (MDA) content at day 7 of storage. The thiol concentration significantly reduced as aging time increased. The band intensities of myosin heavy chain (MHC) and troponin-T significantly decreased as storage progressed, while actin remained relatively stable. After 14 days of aging, tenderness showed significant improvement while muscle pH and drip loss reduced with increase in storage time. Samples aged for 14 days had higher lightness (P<0.05) and lower (P<0.05) yellowness and redness. Post mortem refrigerated storage influenced oxidative and microbial stability and physico-chemical properties of goat meat.
