| Abstract | ||
| An experiment was conducted at the poultry farm – animal resources Dept. – College of Agri. – Univrsity of Baghdad from period of 6 / 10 / 2005 to 22 / 3 / 2006. at 24 Weeks old to study the effect of premix replacement for protien concentrate on laying hen performance and egg interior quality. Sixty ISA Brown laying hen were randomly distributed to five dietarytreatment (0 , 2.0 , 2.01 , 2.02 and 2.03 )% premix with six replicate pen per treatment. Result in dicated that teratment had no significant effect on prodution parameter and egg interior quality measured . However highest egg prodution percentage were obtained in tret.(T5) 95.14% as compared with the other groups . Average egg weight (gm) was higher numerically for (T2) 63.09 gm as compared with the other treatment (T1 , T3 , T4 , and T5) 62.41 , 62.24 , 61.98 , and 62.43 gm respectively . Feed efficiency for (T4 and T5) were 0.96 and 1.9 as compared with (T1 , T2 , and T3 ) 2.06 , 2.43 and 2.01 respectively . Egg specifi gravity and Haugh unit were higher for (T4 and T5) .Meat spot % were lower for (T4) 0.24 % and blood spot percantage was lowest in (T1) control group 0.29 % .While yolk index for the treatment group were higher than the control (T1) group. It coud be concluded from this study that although there were no significant differenceses between the treatments group and the control , but most of the parameter measured were numirically higher at the end of the experiment than the control group beside feed cost was 19.000 thousand I.D. lower than the control group 313.092 VS 332.902 thousand I.D. and this mean a reduction prodution cost of laying hens | ||
