|Resumen : ||With the aim of determine the effect of the month of birth, farm
of origin, weight of the egg, body weight, color and sheen of
eggshell on age at first egg (AFE) in quails, there were evaluated
115 females from fertile eggs acquired in four farms of the
center of the country. The experiment was carried out in the
Agronomy School of the Central University of Venezuela in
sheds of 4mx4m, closed with metallic net, zinc roof and cement
floor, and they were sheltering individual cages of 50 cm.
× 20 cm. The date of birth, weight, color and sheen of eggshell,
body weight, food consumption and egg production were registered.
A completely randomized design was used, and 115 observations
were analyzed by a additive linear model. Only birth
month had a significant (P=0.001) effect on AFE, being April
and December the best months, with differences of 40 days
with regard to the worst month (June). The weight of the egg
affected the EPH (P=0.0022; b =–4.46 ± 1.42 days/g), for
every extra gram of weight of the egg the EPH diminished in
4.46 days; whereas for every extra gram of corporal weight,
EFH increase in 0.52 days (P=0.0001, b=0.52 ± 0.07 days/g).
It can be concluded that the females from heavy eggs and that
they are born in months of minor rainfall, had their first egg
early in life.|
