Effect of Partial Substitution of Dietary Protein by Nigella sativa Meal and Sesame Seed Meal on Performance of Egyptian Lactating Buffaloes

A.E.M. Mahmoud and Wafaa M.A. Ghoneem
This study aimed to find out the impact of partial substitution of dietary protein by Nigella sativa meal (NSM) and Sesame Seed Meal (SSM) on milk yield and composition, digestibility, some of blood parameters as well as economic efficiency. Sixteen lactating multiparous Egyptian buffaloes were used 8 weeks after calving. They were assigned into four groups (4 buffaloes each) to be fed on one of the four experimental rations, each ration consisted of 50% roughages plus 50% of the different concentrate feed mixtures differ in protein source, in 4x4 Latin square design. The experimental rations were as follow, R1: Traditional concentrate feed mixture plus Clover (C) plus Wheat Straw (WS), R2: Concentrate feed mixtures contained 50% NSM as protein source plus C plus WS, R3: Concentrate feed mixtures contained 50% SSM as protein source plus C plus WS and R4: Concentrate feed mixtures contained 25% NSM and 25% SSM as protein source plus C plus WS. No significant (p<0.05) differences among rations in the digestibility of DM, CF, NFE, NDF, cellulose and hemi-cellulose were observed, while, OM, CP, EE and ADF showed significant differences among rations. The 3rd ration recorded the highest TDN (61.79%) followed by control ration (56.61%) however R2 and R3 showed intermediate values. The highest 7% FCM was recorded with buffaloes fed R3 (11.01 kg h-1 day-1) followed by feeding R4, R1 and R2 being 10.56, 10.52 and 10.08 kg h-1 day-1, respectively. In general, the present results indicate that Nigella sativa meal and sesame meal were suitable for feeding lactating buffaloes and formulated balanced rations with adequate protein and energy which will be reflected on good health condition and normal performance of all lactating buffaloes.
