Three non-pregnant multiparous cross-breed Friesian dairy cows were used in this study at same live weights and milk production at cow farm of Technical Agricultural College , Mosul.T he cows were placed in individual pens and fed periodically by using Latin square design (3×3) with three periods (30days/period) on three iso-nitrogen and iso-caloric experimental rations but different in the percentage of bekia seeds (0, 3 and 6%). The results revealed that crude protein and metabolize energy intake, normal and adjusted milk yield, milk fat percentage, quantities of milk fat, protein and lactose were increased significantly (P≤0.05) in 3rd treatment (6% bekia seeds) as compared to those in the 1st treatment ( 0% bekia seeds). While the results indicated that using bekia seeds on three experimental treatments have no significant effect on feed intake of concentrate and straw, total feed intake, percentages of milk protein , lactose ,solid not fat and total solid ,physiological characters such as red and white cell counts, hemoglobin , packed cell volume, total protein, globulin ,albumin, triglycerides, cholesterol ,urea. blood glucose, and concentrations of AST, ALT and ALP enzymes. It could be concluded that using bekia seed to totally substitute the soybean meal in the ration of dairy cows was improved milk production and fat percentage of milk and without a negative effect on all studied physiological blood parameters.
