The Genetic Selection for Four Generations and its Effect on the Blood Biochemical Parameters in the White Quail

This study was conducted in the field of animal production of the college of Agriculture - University of Tikrit from 20/10/2012 until 20/6/2013, the herd was obtained from the General Authority for Agricultural Research in Abu Ghraib which affiliated to the Ministry of Agriculture. The average weight of males and females at five weeks old (150 and 178) grams respectively, with production percentage 70%, collection of eggs from the herd and hatched in a hatchery in the College mentioned above. The study aimed to determine the effect of selection after four generations of the Japanese quail in order to determine the changes in certain blood biochemical parameters. The results showed a significant decrease in the level of cholesterol, glucose, total protein, albumin, globulin and uric acid in the fourth generation compared to the other generations of each of the selected lines.
