الملخص EN

The study has been carried out during the period from 15/9/2010 to 21/12/2010 in a alshalalat farm 15km from Mosul center.

200 chickens of 1day age have been used in which were divided into two parts.

The first one takes the ordinary water while the second takes the magnetized water having the magnetic field of 500 Gauss.

The results as follow:- There are highly significant increases P≤0.01 in second treatment that used Magnetized water in live body weight, body weight gain improved the feed conversion efficiency, water intake, blood pH, packed cells value, number of red and white cells, hemoglobin and total serum protein, and highly significant decrease P≤0.01 in cholesterol, glucose and uriacid in blood serum compared with first.

There are significant differences between the second treatment in weight of (carcass, breast , thigh, wings and neck) and first treatment, this difference was not significant in weight of back and edible viscera between the two treatment.

There is a significant correlation P≤0.01 in the first treatment between the weight of carcass and the components of the carcass except the weight of the carcass and the weight of viscera consumed at a level of P ≤ 0.05 for both treatments but the weight of breast in the second treatment there are no significant differences with the weight of carcass and parts of the carcass.

The analysis of the path coefficient for the first treatment that the neck is the limiting factor of direct and indirect link and suites at the second treatment is the key determinant of direct and indirect link between the parts of the carcass.
