ABSTRACT
Samawal Saadi Abdullah
Al–Tikriti., Heritability of carcass traits in
Japanese quails over 2 generations, Onl J Vet Res., 22 (9):789-792, 2018. One hundred twenty
Japanese quails were reared from day 1 age and allowed to randomly mate to day
21, when females were sexed. Birds were then housed in individual cages and
aged at 1st egg laid as the parental generation. Then
groups of 10 families with 1 male and 3 female were kept in cages to produce a
1st first generation (from the same eggs of parents). Results showed
that offspring had greater (P < 0.01) chest, thighs and back weights but no
significant difference in head, neck, liver, wings or gizzard weights. We
conclude that selection can significantly improve carcass and carcass part
weights in Japanese quails.
