Chemical composition, metabolizable energy and protein efficiency ratio of sesame oil cake (Sesamum indicum L.) for chicken

Chemical composition of sesame oil cake (n=20) were analyzed and the true and apparent metabolizable energy content was estimated in cockerels. The protein efficiency ratio and net protein ratio values of sesame oil cake were estimated and compared with those of other protein sources in broiler chicks by conducting chick growth assay. The sesame oil cake contained (%) 92.6 DM, 32.0 CP, 7.46 CF, 10.1 EE, 38.7 NFE, 12.0 total ash and 2.4 acid insoluble ash. The calcium, phosphorus, sodium chloride, lysine, methionine, free fatty acid, oxalate and aflatoxin B₁ content in sesame oil cake were 2.09%, 0.86%, 1.08%, 2.24 (g/16g N), 2.72 (g/16g N), 2.15%, 3.90% and 2.1 ppb, respectively. The true and apparent metabolizable energy content in sesame oil cake were 2955.2 and 2688.9 kcal/kg, respectively. The protein efficiency ratio and net protein ratio values in broilers fed various vegetable and animal protein feedstuffs infers that the fish meal (5.2 and 3.7) is the superior protein feedstuff for broilers followed by soyabean meal (4.2 and 2.5), sunflower deoiled cake (3.3 and 1.5), groundnut deoiled cake (2.9 and 0.9), sesame oil cake (2.3 and 0.1) and meat and bone meal (2.3 and – 0.5).
