SUMMARY:

Embryo transfer (ET) is the biotechnology most used in horses, one of its biggest problems being embryonic loss in the recipient. Two factors are important causes of these losses: the dysfunction of the corpus luteum (CL), with less progesterone production, and cervical manipulation at the time of ET, which can cause an inflammatory response in the uterus, releasing PGF2α and triggering luteolysis, causing embryo absorption. The objective of the experiment is to verify whether the use of progesterone L.A. associated or not with meloxicam in the recipient on the day of ET, increases the pregnancy rate. The receivers will be divided into 6 groups: 4 of cyclic receivers (I to IV) and 2 of acyclic receivers (V and VI). Being a control group and the others that will receive medication at the time of ET. GROUP I (n = 20) = control; GROUP II (n = 20) 1.5 g of P4 L.A., GROUP III (n = 20) 1.5 g of P4 L.A. and 1.5 g of meloxicam; GROUP IV (n = 20) 1.5 g meloxicam. The two groups of acyclics will be prepared with the same protocol: they will receive 5 ml of Estrogin® (Estradiol Benzoate) on the day on which the donor ovulates and after 48h 1.5 g of P4 LA, after the fourth day of P4 the embryo will be transferred . GROUP V (n = 20) 1.5 g of P4 L.A. and GROUP VI (n = 20) 1.5 g of P4 and 1.5 g of meloxicam. The diagnosis of pregnancy will be carried out seven days after ET and confirmation of pregnancy at 30 and 60 days.

Keywords: progesterone, meloxicam, embryo, equine
