Nutrient composition of bran from new rice varieties under study in Ghana

A study of the nutrient composition of 16 bran samples from 15 new rice varieties being assessed by agronomists and one local variety was conducted. Parameters measured were moisture, fat, crude fibre, protein, ash and mineral content. Carbohydrate and energy levels were calculated from the appropriate data obtained. Results showed significant differences (P < 0.05) in fat, crude fibre and ash contents of samples. With the exception of GRUG 7, ITA 334 and ITA 402, significant differences existed in moisture content. Significant variations (P < 0.05) also existed in protein content with the exception of ITA 304 and ITA 334. The bran from the different rice varieties had appreciably high levels of K, P and Ca. The order of these minerals was potassium, phosphorus and calcium. Energy levels were within the 300 Kcal/100 g range except that of GRUG 7 and BETA which were lower. Ca:P ratios were quite appreciable making the potential use of the samples for feed preparation high. (C) 2002 Elsevier Science Ltd. All rights reserved.
