Selection was practiced for feed conversion ratio by choosing 10% from males and 40%from females to produce the first generation.

Second and third generations were produced by selection 20% from males and 60%from females.

A total of 1670 birds were slaughtered at the age of 35 days for each hatching and generation.

Some of blood pictures and biochemical parameters (serum total protein, cholesterol and glucose) were recorded.

The aim was to select for high and low feed conversion ratio for three generations and its effect on some changes in blood parameters.

Results indicated that birds from high feed conversion ratio, males and birds of third generation showed low cholesterol, glucose and an increase in serum total protein.

Hatchings had no effect on the above traits.
