Abstract EN

This study was conducted at the Poultry Farm of the College of Agriculture, University of Kufa, during the period from 16 September to 3 November-2012, for a period of 7 weeks.

Atotal of 420 day old of Cobb strain broiler chicks were used and evenly distributed randomly over seven treatments (60 chicks/treatment) 3 replicates each treatment with 20 chicks / rep.

The chicks were fed on two rations, Starter ration for the first 21 days of age and Grower ration for the rest 22-49 days of age.

The treatments were as follows : (T0) consists of starter diet which contained 24 % of the diet soybean meal, however the grower diet contained 21 % of the diet soybean meal.

(T1): consists of replacement of water soaked Faba bean for the 1/3 level of the soy beans meal in the diet as protein percentage.

(T2) consists of replacement of treated Faba beans with 1.0 % ascorbic acid for the 1/3 level of the soy bean meal in the diet as protein percentage.(T3) consists of replacement of treated Faba beans with 0.7% Sodium Bicarbonate for the 1/3 level of the soy bean meal in the diet as protein percentage.

(T4) consists of replacement of water soaked Faba bean for the 2/3 level of the soy beans meal in the diet as protein percentage.

(T5) consists of replacement of treated Faba beans with 1.0 % ascorbic acid for the 2/3 level of the soy bean meal in the diet as protein percentage.

(T6) consists of replacement of treated Faba beans with 0.7 % Sodium Bicarbonate for the 2/3 level of the soy bean meal in the diet as protein percentage.

The results indicated that: Dressing percentage of birds in T6 was significantly improved as compared to birds in T4 and T5.

However, T6 didn’t differ from other treatments by giving equal dressing percentage.

Significant differences in means of carcass cut percentages were found among all treatments.

The percentages of liver and gizzard weight in treatment 4 were significantly (P < 0.05) the highest among all treatments.

However, T6 recorded the highest relative weight of heart.

T2 and T5 had the highest significant values in Productive Index and Economical Figure among all treatments.
