RESUMEN
The study was conducted to evaluate breast meat quality attributes of Marshal and FUNAAB Indigenous (Alpha C13 and Alpha C14) Broiler (FIB) chickens. Birds of average live weights (1.8 to 2.0 kg) were selected from flock fed same concentrate diet and managed under deep litter system. Birds were slaughtered, scalded in hot water at 65 °C, de-feathered, and frozen-stored. Proximate, mineral, cholesterol contents, pH, color, and fatty acid profile of the chickens' meat were determined. Data were subjected to ANOVA (p < 0.05). Moisture (73.87%) and fat (2.82%) contents of Marshal were higher than FIB. Protein (23.65%) and ash (1.56%) were highest (p < 0.05) for Alpha C14. pH ranged between 5.94 and 6.58. Lightness (L*) and redness (a*) values were 69.37-75.52 and 8.77-7.96. Alpha C13 had significantly higher L* and a* than Marshal. Potassium was most abundant mineral observed across breeds. Saturated (SFA, 38.03-57.10%), monounsaturated (MUFA, 29.78-41.55%), and polyunsaturated (PUFA, 10.91-20.29%) fatty acid compositions differed significantly among breeds. Cholesterol contents of Alpha C14 (4.23 mg/kg) was significantly lower, while Marshal (5.67 mg/kg) chicken showed significantly higher value. Conclusively, FIB chickens are valuable nutritional meat sources with desirable chemical composition and can constitute alternative chicken meats with human health benefit.

Nutritional quality and essential oil compositions of Thaumatococcus danielli (Benn.) tissue and seed were determined. Oil was extracted from the seed using standard methods while the fatty acids of the oil, chemical and anti-nutritional properties of defatted seed flour were determined. Total fat yield of the seed flour was 12.20%. Defatted seed flour had higher crude fibre (36.92%), carbohydrate (40.07%) and ash (8.17%) contents. Major mineral contents were potassium, calcium, sodium and magnesium. The tissue contain appreciable amount of vitamin C (8.10 mg/100 g). Oleic acid (42.59%) was the major fatty acid in the seed oil and the total unsaturated fatty acid was 62.38%. The seed oil had higher acid and saponification values and low iodine value. Oxalate (11.09 mg/100 g) content was the major anti-nutrient in the defatted seed flour. Defatted T. danielli seed flour serves as good source of dietary fibre and energy.
