Carcass characteristics and meat quality assessment in different quail lines fed on canola seed supplemented diets
(Indian Journal of Animal Sciences, 2020-01) Sabow, Azad Behnan; Haddad, Hurea Saber; Khadijah, Nakyinsige
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.
Sensory and functional properties of iron and folic acid fortified nabe-3 bean and silver fish composite instant flour

Despite the need for Iron and Folic acid (IFA) during critical stages of child development and gestation, there is observed persistence in deficiencies despite medical and intervention efforts. This situation motivated a food-based approach using IFA fortified NARO Bean-3 (NABE-3 bean) and silver fish. IFA fortified composites flours with NABE-3: silver fish proportions as 100:0, 90:10, 80:20, and 70:30 were developed. Functional, pasting and sensory properties were assessed using standard methods. Increasing silverfish proportions in the composite flours was associated with: decreased water absorption properties of the composite flours indicating reduced reconstitution abilities; reduced final viscosity but increased bulk density implying a high density of nutrients at lower viscosity and volume; increased peak time indicating increased cooking energy requirements; and reduced sensory acceptability [from liked moderately (7) to indifferent (5) on a 9-point hedonic scale] due to darkening of the colour, and increased intensity of fishy aroma and flavour. The 90:10 and 80:20 composites were more acceptable than the 70:30. The compressibility and hausner ratios of the flours were high and not significantly different, indicating low flowability of the bean flour and its composites with silver fish. Technological improvements should therefore maximize nutritional value while ensuring sensory acceptability and functionality.
