| Abstract | ||
| The present study is conducted at the Poultry Farm / Department of Animal Resources at College of Agriculture / University of Baghdad / Abu-Ghraib , from 15/10/2004 until 30/9/2005. The objective of the study is genetic evaluation of White Leghorn flock for selection according to certain blood biochemical traits. Animal Model program was used for evaluation of white leghorn individuals to estimate breeding values for sires (24) Dams (128) and their progeny (352). These values were sorted according to breeding values for selection objectives. Rank correlation coefficient was calculated between blood traits breeding values estimation and between blood and production traits. Results showed there are wide ranges in breeding values estimates for white Leghorn individuals, especially for serum cholesterol level, which refer to additive genetic variance that could be used in selection programs. | ||
