Nutritive evaluation of Sago fibre
D. P. Yadav, M. Mahyuddin
Nutrient evaluation of sago fibre showed that the fibre has potential and could be utilized as feed for ruminants. However, as a source of nutrients, it has limitations arising from low intake, digestibility, crude protein and minerals content. The present study showed that the sago fibre is low in crude protein (3.3%) and high in neutral detergent fibre (72.5%) and acid detergent lignin (25.8%) contents. Treatment of sago fibre with urea increased the crude protein content from 3.3 to 16.7%. Both urea and sodium hydroxide treatment decreased the neutral detergent fibre level from 72.5 to 59 and 56.5%, respectively. Rumen degradation of sago fibre by nylon bag showed that both urea and sodium hydroxide treatments increased dry matter and organic matter disappearance of the fibre significantly. In vivo digestibility of 2% urea treated sago fibre was 47.5% and intake of the fibre was 1.57% of body weight of the lamb.
