This study examined how extruded-pressed soybean meal (EP-SBM) affected the growth performance and economic efficiency of broiler chicks. Three groups of 198 unsexed one-day-old chicks (Ross 308) total were created at random (3 replicate/22 bird/replicate). Isocaloric and Isonitrogenous diets were as follows: G1 (control) (basal diet +soybean meal 46%), G2, basal diet + (EP-SBM) (5, 10, and 20% for starter, grower, and finisher). G3, basal diet + (10, 15, and 25 % (EP-SBM) for starter, grower, and finisher) for 42 days. Body weight significantly differed on days 7, 14, 21, and 28 (881.41, 744.3, and 774.83 g/bird, for G3, G2, and G1 on day 28, respectively). Body weight gain increased significantly on day7 and 14 for G2 and G3 than G1 (138.96, 99.49 and 92.68 g/bird on day 14 for G3, G2 and G1, respectively). Feed intake differed significantly during 1st and 2nd weeks. Feed conversion rate increased significantly during 1st and 2nd weeks for G1 than for G2 and G3. Compared to G2 and G3, The addition of Extruded-pressed SBM resulted in a lower total feed cost, total variable cost, and total cost than G1, which recorded the highest value. Regarding return parameters, they showed a non-significant difference and a non-significant decrease in the cost of each kg of body weight and body weight gain from a feed. It was concluded that Extruded-pressed SBM improved performance and economic efficiency, so; it could be added to broiler diets. |
