The study was conducted on (50) Friesian cows age (2.5 -5) years with different nutritional levels, suffering from dysfunction ovary for the period (40-55) days after birth of the year (2019). In the milk cows station (Faiha) / Babylon province. To treat the cases and then follow back to the estrus and use artificial insemination with follow-up pregnancy. The study relied on dietary and hormonal therapy during the open period of adult (110-125) days, cows were divided into two groups (non-functional ovaries and control), which consecutively was divided into three sub groups, including control and treatments. hormone therapy must be linked to poor food. Weaknesses or functional delays are not recommended to used hormonal therapy unless the animal’s health and nutritional status are improved, As well as the genetic status of the animal dependent on breed selection in terms of nutritional conversion and access to sexual puberty and its ability to maintain the balance of energy is the most important thing that makes the animal in the normal situation in terms of production during his life. Progesterone and GnRH therapy also play a role in the reactivation of ovaries in cases of delayed and hostile. Functional delays are also easier to treat, which is done by dietary improvement only and may not need hormone therapy, especially after adjusting the nutritional status in particular. We conclude from this study that the nutrition improvement before and after birth and improve the quality is the most important things in the management and breeding of animals and during their life cycle before puberty and focus on the postpartum period to restore the animal to its normal functional activity.
