Efficiency of using meloxicam and dexamethasone in superovulation induction regimens for donor cows
Abstract
Currently, there is a need to improve the regimens for inducing superovulation in cows in order to increase the number of animals responding to the administered hormonal drugs and to obtain embryonic material from them suitable for transplantation. However, preparations of follicle-stimulating hormone used to induce multiple ovulation are not always capable of causing a response in the animal to the administered gonadotropin. Therefore, in embryo transplantation technology, along with gonadotropins it is necessary to use drugs that have general strengthening and immunomodulatory effects, acting on the ovaries of animals indirectly. The paper contains the results of research aimed at studying the effect of immunomodulatory drugs meloxicam and dexamethasone in superovulation induction regimens for donor cows. It has been established that the use of solutions of these drugs in the hormonal treatment regimens for donor cows during the induction of polyovulation does not adversely affect the morphological and qualitative composition of intact cattle embryos, allows obtaining more embryos suitable for transplantation and reducing the number of rejected cells.
