Abstract
This study was aimed to evaluate chemical compositions, profiles of amino acids and fatty acids, vitamin and sex hormone contents of eggs from chicken, quail and snail-eating turtle, respectively. Whole quail egg had higher levels of fat (9.89 g 100g-1), and energy (156.50 kcal 100g-1) than the others. Snail-eating turtle egg contained the highest levels of total solids (5.36%) and ash (1.45 g 100g-1). Total of amino acids content of either quail or chicken egg white (10.78 or 9.33 g 100g-1) was higher than that of snail-eating turtle. Ratio of unsaturated and saturated fatty acids content found the highest in snail-eating turtle eggs. Quail egg yolks contained the highest content of vitamin A (retinol) and D (717.00 and 1.14 μg 100g-1), while the chicken egg contained the highest level of vitamin E (6.37 mg 100g-1). Most of sex hormones content; Luteinizing Hormone (LH), Follicle Stimulating Hormone (FSH), Prolactin (PRL), Progesterone (P), Estradiol (E2) and Testosterone (T), were high in egg yolks. Whole eggs of chicken egg contained the highest content of hormone P (807.06 ng g-1) which was higher than that of quail or snail-eating turtle (314.83 or 157.36 ng g-1). This study indicated that quail egg contained higher contents of amino acid, such as aspartic acid and leucine, vitamin A and D, than the others. While, the chicken egg contained higher levels of vitamin E and sex hormones P than the others. Total minerals were the most abundant in snail-eating turtle egg.
