The effects of dietary supplementation with rice bran crude lecithin (RBCL) on rumen fermentation and blood biochemical parameters in crossbred cattle were investigated in the present study. For the study, 18 male crossbred Vrindavani cattle (BW 315.66±19.95 kg and 30-36 months of age) were selected and randomly divided into three groups, namely, RBCL-0, RBCL-4, and RBCL-8, containing six animals per group based on a randomized block design (RBD) and offered a total mixed ration (TMR) supplemented with 0, 4, and 8% RBCL in their concentrate mixture, respectively. The rumen pH was unaffected by RBCL supplementation, whereas the ammonia nitrogen (NH3-N) concentration was increased in the RBCL-supplemented groups. The molar concentrations of acetate, butyrate, and TVFA were unaffected, whereas the propionate concentration increased and the A/P ratio decreased in the RBCL-supplemented groups. The activity of rumen microbial enzymes (carboxy methyl cellulase, xylanase, and avicelase) was not influenced by RBCL supplementation. The inclusion of RBCL in crossbred cattle diet did not significantly alter Hb, haematocrit, total protein, albumin, globulin, A/G ratio, BUN, ALT, AST, and total cholesterol. It can be concluded that supplementation of RBCL by replacing an equal amount of corn did not show any adverse effect on rumen fermentation and blood-biochemical profile.
