Abstract

Egg has all the nutrients that people need. They have the richest proteins found in foods, contain proteins that cannot be secreted by the body and must be taken from the outside. The present study was conducted in order to show how aging and lighting can affect the yield and quality of egg. In this study, 6 female quails under 40 groups were used to investigate the egg yield and weight of egg that stars with the first ovulation and for a period of 12 months. Egg count and weight of quails that were kept in separate and individual cages. Two groups were investigated for 20W florescence light and daylight conditions separately. Yearly average egg yield of 282.42 calculated as population average was distributed along days 0-124, 125-248 and 249-372 as 39.85%, 34.66% and 25.49% respectively. The ratios of percentage of eggs obtained between days 125-248 and 249-372 to days 0-124 were calculated as 92.59% and 72.53% respectively It is concluded that egg yield with an average of 282.42 eggs per quail for a period of 12 months following the age of first ovulation was stable until month 8.
