Abstract: The study was carried out to evaluate the reproductive performance of Arabi ewes and inspect the impact of Anethum graveolens seeds on the concentrations of some hormones and the histological changes that occurred in the ovaries, uterus, and mammary glands during estrus and pregnancy. The number of ewes were 16, ranging in age from (1.5-2) years and varying weights (45-53) kg, with the presence of three rams ranging in age from (2-3) years and weights (65-75) kg during the mating period only. A significant effect (P<0.01, P<0.05) of Anethum graveolens seeds on the average concentration of estrogen hormone between the treatments. There was a significant difference (P<0.01) in the average progesterone concentration. A significant difference (P< 0.01) in the average concentration of prolactin hormone. A histological examination of the uterus revealed no pathological changes in the endometrium, myometrium, or perimetrium. Also, there were no pathological changes in the ovary. A histological examination of the mammary gland shows that Anethum graveolens causes a small rise in the estrogen and progesterone receptors, which are connected to the mammary glands' ducts and alveoli, and results in a tiny enlargement of those glands. So, we recommend giving dill seeds to ewes to increase milk production.
