ABSTRACT

Poultry eggs are eaten in most areas of the world with fewer social taboos associated with them than pigs and cattle. The most commonly used bird eggs are those from chicken. In Nigeria, the domestic foul dominates the poultry industry. Of the 120 million indigenous poultry population in Nigeria, the domestic fowl constitutes about 91 % of this. For this reason, the present work tried to evaluate the nutritional levels of the lipid composition of the free-range fertilized cooked chicken eggs. Five eggs were involved in the study and they were collected at once. The following experimental procedures were carried out on the yolk and the albumen using standard analytical methods: crude fat determination, preparation of methyl esters and fatty acid analysis. Also determined was the quality assurance of the determinations to ensure their accuracies, calculation of uncertainty interval percentage (UIP) particularly for the fatty acid values.
