“…Sometimes, the embryo recovery rate after inducing superovulation can be low since a large clot form in the ovulation fossa when the ovary ovulates [15]. Which alters the transport of oocytes to the oviduct where fertilization by sperm occurs.…”

Equine reproductive efficiency can be improved through the development of technologies such as embryo transfer, where the use of protocols that allow the presence of double ovulations can contribute to increasing the number of offspring per female per year. The objective was to evaluate the presence of double ovulation and embryos in Colombian Creole mares treated with deslorelin and histrelin. Twenty mares were taken and divided into 2 groups as follows: Treatment 1: 150 mg of deslorelin every 12 hours intramuscularly. Treatment 2: 80 mg of histrelin every 12 hours intramuscularly. In both treatments, the hormone was administered until two follicles with diameters greater than 35 mm were found to administer 2,000 U. I of human chorionic gonadotropin and were artificially inseminated 12 to 24 hours later with 300 million motile spermatozoa. Seven days after insemination, uterine lavage was performed to collect embryos. It was found that 60% of the females treated with histrelin presented double ovulation with a follicular diameter of 31.7 mm, and 8 mares had double embryos, while 45% of the mares treated with deslorelin presented double ovulation with a follicular diameter of 33 mm, and 5 mares had double embryos. An association between the presence of double ovulation and the presence of embryos was found in 45% of the mares treated with deslorelin. It is concluded that histrelin treatment presented better results in obtaining double ovulation in mares.

“…The success of assisted reproductive technologies (ART) is significantly increased in mono-ovulatory species if the number of mature follicles in which mature oocytes may be retrieved is maximised, as this increases the likelihood of one oocyte being able to develop to pregnancy. A superovulation protocol is intended to increase the numbers of mature follicles on ovaries by manipulating the pituitary-derived hormones present in the body and maximise the possibility of developing an embryo that produces a live birth (Callesen, 2019).…”

<p><strong>This research aimed to test methods of incubation media concentration to increase detection of contaminant miRNAs, to determine if contaminant miRNAs present in incubation media were of a sufficient quantity to interfere with the secreted miRNA profile of an incubated embryo, and to characterise the associations of contaminant and embryo-derived miRNAs in terms of Ago2 protein association, and microvesicles association.</strong></p>
