Abstract

Fertility and hatchability rates were studied in two breeds - A and B - of the domestic fowl, composed of sire (As and Bs) and dam (Ad and Bd) grandparent strains respectively. The dam strain (Ad) of A had the highest percent hatchability of 73.18%. The sire strain (Bs) of B had the highest proportion of eggs with dead germ followed by both the Ba and As lines whose values were significantly the same. Chick embryo mortality was most critical between the 18th and 21st day of incubation in all strains. The results further show that the A breed had higher rates of fertility and hatchability than the B breed, and that the dam and sire strains of both breeds performed differently with regards to the traits examined.
