title: [Use of chigo (Campsiandra comosa Benth) seeds in human nutrition. III. Energetic value of chiga flour].
abstract: The proximate composition as well as vitamin and mineral contents of a sample of chiga (Campsiandra comosa Benth) flour was analyzed, having determined that it was essentially a carbohydrate source. The product was evaluated as source of energy, substituting 33, 67 and 100% of the corn starch of isoproteic and isocaloric feeds for growing Sprague-Dawley rats. In an experimental period of 15 days, results indicated that the substitution of one-third of the carbohydrate with chiga flour did not reduce the weight gain, food consumption, metabolizable energy or utilization of the food energy by the rats. Higher levels of the product in the diet originated a decrement in these variable values. The apparent nitrogen and energy digestibility of the diets was progressively reduced as the concentration range of chiga flour utilized was increased. The metabolizable energy value of chiga flour was 3.15 kcal/g, which indicated that approximately 78% of its gross energy (4.01 kcal/g) was metabolized.
