Abstract
This study was conducted in the poultry field of the Department of Animal Production - College of Agriculture - University of Kirkuk for the period from 1/5/2024 to 6/8/2024, to study the genetic correlation of productive, egg quality and biochemical traits of laying hens. 120 Lohmann Brown laying hens aged 64 weeks, placed in vertical battery cages. Each battery contained 4 floors, and each floor contained 3 cages. The dimensions of each cage were (35 x 30 x 40 cm) in length, width, and height, respectively. The results indicated a negative and significant genetic correlation between blood cholesterol level and egg production rate, egg weight and egg mass, while the genetic correlation was positive and significant between cholesterol and the feed conversion ratio. A negative and significant genetic correlation was also recorded between the AST enzyme in the blood and egg production rate, egg weight and egg mass, while the genetic correlation was positive and significant between the AST enzyme and the feed conversion ratio. On the other hand, a positive and highly significant genetic correlation was observed between the level of cholesterol in the blood and the yolk index, as well as a positive and significant genetic correlation between the AST enzyme and the two traits of the yolk index and the shell thickness. Thy study recommending to use indirect genetic improvement programs based on some biochemical traits in blood serum (glucose, total protein, cholesterol, AST and ALT enzymes) due to their positive and significant correlation with productive performance and egg quality traits in laying hens.
