| dc.description.abstract | A 20-week feeding trial involving 72 Isa brown-laying birds, in a completely randomized design, evaluated the nutrient digestibility and egg production of layers fed diets containing biodegraded palm kernel meal (PKM) at dietary levels of 20 per cent undegraded and 20, 30 and 40 per cent biodegraded PKM, respectively. Biodegradation slightly improved proximate and detergent fibre components compared to the undegraded sample. Among the fibre fractions, hemicellulose was most degraded, whereas acid detergent lignin was least. Proximate component digestibility was similar among the diets except at 40 per cent levels. With the detergent fibre component, increasing the level of the biodegraded PKM caused a significant difference (P<0.05) in fibre component digestibility. Increase in the quantity of biodegraded PKM resulted in significant differences in the values determined for feed intake, hen-day production, and average egg weight; but for egg length, yolk index, egg/yolk ratio and egg shell thickness, there was no significant difference. Despite the significantly lower hen-day production of Diet 3, the feed cost per egg produced was similar to the value determined for birds on Diet 1. It could, therefore, be concluded that when prices for soybean meal and maize are high , up to 30 per cent PKM could be used in layers’ diets. | en_US |
