description The aim of this study was to evaluate the chemical composition of jatoba-do-cerrado flour and its effects on rat's growth. The chemical composition of the flour was determined according to AOAC. The PER, NPR, food efficiency ratio (FER), food conversion ratio (FCR), dry matter digestibility (DMD) and fecal output were evaluated by an assay in which animals were fed according the AIN93 diet: casein (CAS) diet and another having 50% of its protein source from jatoba flour (JAT). Chemical analysis showed significant amounts of crude fibre and minerals (potassium, magnesium, calcium and zinc) in the flour. The CAS group ate more and gained more weight than JAT group (p

Chemical analysis showed significant amounts of crude fibre and minerals (potassium, magnesium, calcium and zinc) in the flour. The CAS group ate more and gained more weight than JAT group (p<0.05). JAT was less efficient on converting diet in body weight. PER was lower for JAT (p<0.05), but no significant difference was observed for NPR values (p>0.05). Faeces moisture and dried weight for JAT were higher, which corroborated its lower DMD (p<0.05). Although JAT group had to intake more diet to promote weight gain, the protein utilization was acceptable. Therefore, further studies are necessary for better understand nutrient and phytochemical composition, their bioavailability, and metabolic effects of jatoba-do-cerrado flour.

O objetivo deste estudo foi avaliar a composicao quimica da farinha de jatoba-do-cerrado e os seus efeitos sobre o crescimento de ratos. A composicao quimica da farinha foi determinada segundo a AOAC. Os indices PER, NPR, Quocientes de Eficiencia Alimentar (CEA) e Conversao Alimentar (CCA), digestibilidade da materia seca (DMD) e a excrecao fecal foram avaliados por ensaio em que os animais foram alimentados com dietas baseadas na AIN-93G: caseina (CAS) e outra com 50% da fonte de proteina oriunda da farinha de jatoba (JAT). A analise quimica mostrou quantidades significativas de fibra bruta e minerais (potassio, magnesio, calcio e zinco) na farinha. O grupo CAS obteve maior ingestao e ganho de peso com relacao ao JAT (p<0,05). JAT foi menos eficiente em converter a dieta em peso corporal. O PER foi menor no grupo JAT (p<0,05), mas nao foi observada diferenca significativa para valores de NPR (p>0,05). A umidade e peso seco das fezes do grupo JAT foram maiores, o que corroborou sua menor DMD (p<0,05). O grupo JAT precisou ingerir mais dieta para ganhar peso, mas a utilizacao proteica foi satisfatoria.
