AB  - The study aimed to evaluate the hatchability,
fertility and egg quality traits of exotic dual purpose
chicken crosses of Koekoek (K) and Kurioler (Ku)) with an
improved Horro chicken (H) under reciprocal mating. The
experiment was carried on seven genotypes, including
three pure lines (H, K, Ku) and their direct crosses (K×H,
Ku×H and reciprocal crosses (H×K, H×Ku). A total of 446
a-day-old chicks from the seven genotypes were distributed
randomly to pens with three replications per genotype in a
completely randomized design. A total of 700 hatching
eggs; 100 of eggs from each genotype were collected and
hatched for determination of egg fertility and hatchability
traits in percentage. After the start of three month of egg
laying, 15 eggs per genotypes were randomly selected and
used for external and internal egg quality traits
determination. In comparing fertility of crossbreds, no
significant (p>0.05) differences were observed among
genotypes and the fertility rate ranged from 86.2 to 91.44%
for Ku×H and H×K respectively. The highest hatchability
from fertile egg was recorded for Kuroiler (86.02%)
followed by improved Horro chickens (80.73%). No
significant differences were observed among the genotype
for all egg quality traits, except for egg weight, shell
weight and albumen width. In comparing whole genotypes,
significantly highest (p<0.05) egg weight was observed for
Ku&times;Ku, Ku&times;H and H&times;K crossbred hens whereas the
lowest egg weight was observed for improved Horro and
the other genotypes have shown comparable performance
for most studied egg quality traits including egg weight.
Slightly quite improvement was observed among the
crossbred of both Kuroiler- crosses and Koekoek-crosses
in fertility and hatchability traits. Hence, some of internal
and external egg quality traits are found to be improved in
crossbred chicken than the improved Horro chicken in the
crossbreeding schemes.
