Abstract: Ten pregnant Saharawi camel breed were used to determine the effect of diet on the profile of blood parameters (biochemical and hormonal) in peri-partum and the kinetics of follicular development combined with ostrogen 17β and progesterone assays after calving. The animals were divided into two groups of five camels: the “S” group who received food from concentrate, hay and forage and the “NS” group not supplemented with green forage. Blood samples were collected at 30, 15 and 2 days before birth and on a weekly basis from the 2nd to the 40th day after parturition. The resumption of ovarian activity was monitored by ultrasonography from 10th-40th day after parturition. With the approach of parturition, protein and energy, lipid and mineral parameters increased in all camels (p<0.05). After parturition, protein-energy factors, minerals and progesterone decreased (p<0.05) gradually from day 2 until a physiological level at day 40. The gestational state had a significant effect on glucose (R2 = 0.79), progesterone (R2 = 0.93) and oestradiol 17β (R2 = 0.95) in plasma. The supplemented camels showed a higher biochemical and mineral status (p<0.001) while triglycerides strongly decreased (p<0.001). The study showed a positive correlation between the size of the follicles and the kinetics of oestrogen 17β (r = 0.718 to 0.762). A negative correlation was observed between the values of oestrogen 17β and progesterone in plasma (r = 0.11 to 0.43).
