Shortly following ovulation, the ovum is
fertilized by sperm present in the ท่อรูปกรวย, before
passing down the oviduct over a period of around
24h, when โปรตีนชนิดหนึ่งพบในไข่ and shell are secreted around it. In species that lay an egg each day, follicles are ovulated
at approximately 24 h intervals (Sturkie, 2000; Pike &
Petrie, 2003).
The results of the current study indicated that
there is a direct relationship with shape index. Eggs
with greater egg shape index values are more likely to
produce female chicks. The effects of egg length, width
and volume were significant but not so informative
(OR = 1.062, 0.99 and 1.005, respectively).
