The aim of the present study was to examine the effects of dietary supplementation of Bergapur (BR) with and without choline chloride (CH) on growth performance, feed utilization, serum biochemical and hematological indices of Oreochromis niloticus. Nile tilapia juvenile fed five treatments  (A control diet and four other diets were formulated to include the fine powder and  Bergapur (BR) with and without choline chloride (CH) as a follows: {T1(Control), T2 (0.01 BR), T3 (0.02 BR), T4  (0.01 BR + 0.04 CH), and   (0.02 BR + 0.04 CH)} of a Bergapur (BR) a commercial product containing Deoiled lecithin, 97% (pure lecithin) and Highest phospholipid with and without choline chloride (CH) for 84 days. After the experimental period, statistical analyses of the obtained results showed that the highest significant higher FBW, WG%, DWG, FI, FE and SGR (P<0.05) in fish feed T5 (0.02BR+0.04CH/kg) diet, compared with the control. In addition to that the feed conversion ratio was significantly decreased in fish fed T4 (0.01BR+0.04CH/kg) and T5 (0.02BR+0.04CH/kg) (P<0.05). The hematological indices, specifically Hb, PCV, RBCs, and WBCs (p ≤ 0.05) were significantly improved for Nile tilapia fish fed diet a blend of Bergapur (BR) and choline chloride (CH). Whereas, no marked effects of using Bergapur (BR) and choline chloride (CH) on the blood biochemical traits of Nile tilapia juvenile. Moreover, Fish fed higher dietary inclusion of Bergapur (BR) and choline chloride (CH) significantly increased serum biochemical blood of Nile tilapia juvenile compared to other experimental groups. Consequently, Bergapur (BR) and choline chloride (CH) is recommended at a level of T5 (0.02BR+0.04CH/ kg−1) diet, to improve the growth performance, feed utilization and blood health of Nile tilapia fish.
