Nutritional Composition of Oven Dried Eggs Produced from Isa-Brown Hens Fed Composite Leaf Meal-Based Diets

Abstract

The study investigated effects of diet compositions on nutrient composition of oven dried eggs. Eggs were obtained from birds fed composite leaf meal (CLM) and separated as egg white, egg yolk and whole egg. The separated portions and whole egg were homogenized separately. The samples were oven-dried at 40°C and allowed to cool. The different portions of the egg flakes were milled, sieved and proximate analysis was done. For the egg white, highest crude protein (71.83%) was recorded in egg from birds fed 5% CLM and lowest (62.88%) in egg from birds fed 0% CLM. For egg yolk, highest carbohydrate 38.66% was observed in egg from bird fed 0% CLM and lowest 25.50% in egg from bird fed 5% CLM. Food energy varied; 528.02g/cal to 544.56g/cal in egg obtained from bird fed 2% and 1% CLM, respectively. The crude protein of the whole egg varied; 48.40% (0%) - 56.15% (5% CLM). From the results, it could be concluded that the nutrient composition of the egg white, egg yolk and whole egg were affected by the levels of CLM in the diet.
