Abstract
The effect of decortication and extrusion on apparent protein digestibility of sorghum (Sorghum vulgare) was evaluated in comparative balance studies in 9 children 7 to 24 months old. Sorghum provided (as kcal) 8% protein and 62% carbohydrate in the study diet. Lysine was supplemented to 3% of protein. Casein provided 6.4% protein kcal in the control diet. A mixture of sucrose, dextrimaltose and maize starch provided carbohydrate. Both diets contained 30% fat kcal as soya bean-cottonseed oil blend. Balance studies were made during the last 6 days of three 9-day dietary periods: control-sorghum-control. Apparent N absorption from sorghum was 81 ± 4% and did not differ from control. Apparent N retention, 21 ± 6%, was lower than the preceding control 27 ± 8%, and following control (33 ± 7%) values. The control values differed significantly from each other. Faecal weights and energy losses showed only minor differences between the 2 diets. The results contrast sharply with previous results obtained with whole-grain sorghum and suggest that the use of decortication and low cost extrusion processing can considerably improve the apparent protein quality and digestibility of sorghum
