Effects of timing of induced luteolysis in embryo donor mares on reproductive performance and pregnancy rate in recipient mares
(Elsevier B.V., 2011-04-01)
The objective was to evaluate the effects of giving prostaglandin F(2 alpha) (PGF) to donor mares 48 h prior to embryo collection. Non-lactating donor mares (n = 20 estrous cycles in 10 mares), ranging from 2.5 to 10 y of ...

Embryo Transfer Efficiency of Quarter Horse Athletic Mares
(Elsevier B.V., 2011-12-01)
This study was designed to compare embryo recovery rates and pregnancy rates of athletic and breeding Quarter Horse mares in a tropical warm climate. Thirty-nine barrel racing mares in training and 135 breeding mares as ...

Factors affecting pregnancy rates for goat embryos recovered and transferred by transcervical route
(Elsevier B.V., 2020-11-01)
This study evaluated the factors affecting non-surgical embryo transfer (NSET) efficiency in goats. Donor goats (n = 10) were superovulated, mated and embryos were collected by non-surgical embryo recovery 7 d after estrous ...
Use of Equine Pituitary Extract (EPE) in low doses to induce double ovulation in mares
(2017-01-01)
The aim of this study was to evaluate the effect of treatment using low doses of EPE on rates of ovulation and embryo recovery. Eight mares were used in this way: first cycle (n = 8)-control group (untreated); second cycle ...
Recoleta uterina como estratégia para aumentar a taxa de embriões em fêmeas bovinas de corte e leite
(UNIV FED RIO GRANDE DO SUL, 2008)
Embryo recovery rate in superovulated cows after uterine flushing is lower than the ovulation rate, which contributes to the relative inefficiency of the conventional cervical recovery procedure. A simple and easy alternative ...
Preovulatory follicular dynamics, ovulatory response and embryo yield in Lacaune ewes subjected to synchronous estrus induction protocols and non-surgical embryo recovery
(Elsevier B.V., 2020-03-15)
The objective of this study was to assess the effect of the duration of progesterone-based estrus induction protocols on preovulatory follicular dynamics, ovulatory response, and embryo yield after non-surgical embryo ...
Cervical penetration rates and efficiency of non-surgical embryo recovery in estrous-synchronized Santa Ines ewes after administration of estradiol ester (benzoate or cypionate) in combination with d-cloprostenol and oxytocin
(Elsevier B.V., 2019-04-01)
The effects of estradiol esters, D-cloprostenol and oxytocin on induction of cervical dilation prior to non-surgical embryo recovery in Santa Ines ewes (Days 6-7 estrous cycle) were assessed in this study. In Trial 1, ...
