The aim of this study was to determine the effects of feeding on date palm (Tamr) on hematological and biochemical parameters of pregnant rats. Thirty-five adult healthy female's albino rats (3-4 month old and weighing 100-150 gm) were used. Rats were divided into five equal groups after meeting and assuring of pregnancy, the experimental meal was introduced to each group. The first groups were fed by standard meal, while the second, third, fourth and fifth group was fed by meals that total carbohydrates was exchanged by proportion 25, 50, 75, 100% dates from type of Sukkari Al Qasim, respectively, throughout the 4-week experimental period. Blood withdraw after one, two week of pregnancy and after delivery to determine hematological and biochemical characteristics. The total erythrocyte, hemoglobin and hematocrit were increased in the four experimental groups. Total leukocyte count was increased in control group comparison with 25, 50, and 75% dates. Serum albumin level was increased in rats' groups of 25, 50 and 75% dates compared to control group. Urea, creatinine, triglyceride and both of low and very low density lipoprotein were decreased in all experimental groups compared to control. Blood glucose and high-density lipoprotein level was increased in the four experimental groups compared to control. The present study indicated that feeding on date palm (Tamr) (25, 50, 75 and 100%) improved the hematological and biochemical parameters of pregnant  and  lactating rats.
