Abstract:

The study was conducted to evaluate effects of replacing different levels of sceerened red haricot bean (SRHB) for soybean meal on dry matter intake, body weight gain, egg production, egg quality, feed conversion ratio, fertility, hatchability, chick quality of white leghorn chicken, and economic profitability. A total of 225 (195 hens + 30 cocks) at age of 30 weeks with initial body weight of 1104.7± 16.35 gram were randomly distributed in to 15 pens each with 13 hens and 2 cocks. The pens were randomly allocated to five treatments diets in CRD. The five treatment diets used in this study were containing 0%, 20%, 40%, 60%, and 80% of SRHB and 100%, 80%, 60%, 40% and 20% soybean meal for T1, T2, T3, T4 and T5, respectively. The SRHB contained 29.01% CP and 3276 MEKcal/K g DM. Dry matter intake (92.5, 95.03, 91.03, 90.09 and 89.7 (SEM= 0.75) for T1, T2, T3, T4 and T5, respectively, was significantly (P < 0.05) different which is high in T2 and low in T5. Hen day egg production (51.82, 54.67, 48.25, 46.7 and 41.45 (SEM=0.87) and Hen house egg production (50.45, 54.67, 48.25, 45.49 and 41.45 (SEM=0.91) for T1, T2, T3, T4 and T5, respectively were significantly (P < 0.05) different which was high T2 and low in T5. Relatively high number of eggs was obtained from T2 at which the two protein diets (SRHB:SBM) were companied at a ratio of 20:80%, respectively. Feed conversion ratio 3.51, 3.48, 3.71, 3.83 and 4.37 (SEM=0.13) and egg mass 26.35, 27.28, 24.53, 23.47 and 20.49 (SEM= 0.6) for T1, T2, T3, T4, and T5, respectively were statistically (P0.05) among treatments on average daily body weight gain per bird, egg weight, shell weight, shell thickness, albumen quality, yolk weight, yolk diameter, yolk height, fertility, hatchability, embryonic mortality and chick quality. Yolk color and index were significantly (P
