This study was conducted to evaluate body weights, average daily gain (ADG), relative growth
rate (RGR), average egg weight, hen day egg production% (HDEP%), hen housed egg
production% (HHEP%), age at sexual maturity, body weight at sexual maturity, fertil
ity%,
scientific and commercial hatchability percentage in a complete 2x2 diallel crossbreeding
experiment [Fayoumi and Rhode Island Red (RIR)].
RIR showed significant (p ≤ 0.05) higher
body weight, ADG, RGR, age at sexual maturity and body weight at sexua
l maturity (1898.76
g, 9.04 g, 19 3.95%, 144.66 day and 1559.05 g, respectively) compared other genotypes.
In
addition
, RIR recorded the highest egg weight, fertility
percentage
, scientific and commercial
hatchability percentage (44.28 g, 85.59%, 94.91% an
d 81.49%, respectively). While Fayoumi
male×RIR
female crossbred
recorded the highest significant estimate for HDEP
% and
HHEP
% (54.41 and 51.65%). |
