This study evaluated reproductive features and role of Flunixin-Meglumine at timed artificial insemination (AI), using a new technique of standing position with cervix immobilization. In Experiment 1, 10 goats (n=5 nulliparous [Null] and 5 pluriparous [Plu]) were evaluated after estrus induction by recorded reproductive parameters to define the ideal time(More)
In vivo, the oviduct provides appropriate microenvironment conditions for monospermic fertilization and early embryo development. In addition, glycosaminoglycans such as heparin are present in the oviduct and have been shown to modulate the activity of oviduct-secreted proteins on the regulation of sperms parameters. Thus, the present study was designed to(More)
The aim of this study was to evaluate the effect of (i) the duration of hormone treatment with progestogen sponges during the seasonal anestrus and (ii) the administration of two doses of prostaglandin at 7 days apart during the breeding season on reproductive parameters of Santa Inês ewes. In experiment 1, 32 ewes received intravaginal MAP sponges for 6(More)
The embryo transfer techniques used in small ruminants worldwide are based in surgical procedures. These actions are performed under general anesthesia which needs a combination of animal fasting and drugs for secure animal handling and surgery manipulations. Therefore, it involves risks to animal health and life. The major limiting sequels are adhesions(More)
A total of 3427 goat oocytes were used in this study to identify possible differences during in vitro embryo production from slaughterhouse or laparoscopic ovum pick up (LOPU) oocytes. In experiment 1, one complex, one semi-defined, and one simplified IVM media were compared using slaughterhouse oocytes. In experiment 2, we checked the effect of oocyte(More)
Although cumulus cells are essential for efficient oocyte maturation, the establishment of protocols that support IVD of embryos obtained from denuded oocytes (DOCs) is important for optimizing the use of reproductive biotechnologies. Thus, this study aimed to establish a protocol for IVD of goat DOC using different strategies of IVM and methods of oocyte(More)
This study evaluated the effect of the protected fatty acid inclusion during estrus synchronization on reproductive parameters. Goats (n = 32) received progestagen sponges for 6 days and 200 IU equine chorionic gonadotropin and 30 µg d-cloprostenol were given on Day 5. No difference was found among control (C), 1% protected fatty acid inclusion (C + 1%) or(More)
The aim of the present study was to compare hormonal treatments to induce and synchronize follicular wave emergence to improve the results of superovulatory (SOV) treatments in ewes. In Experiment 1 (n = 66), ewes were treated with a progesterone intravaginal implant plus a PGF2α analogue (group GP4), or with the same treatment plus estradiol benzoate(More)
This study evaluated the effect of two doses of prostaglandin at different intervals on reproductive parameters of crossbred ewes. In Experiment 1, 30 ewes received two doses of 120 μg cloprostenol at 7 (G 7 days), 9 (G 9 days), or 11.5 (G 11.5 days) days apart. Ultrasound assessments were performed from the first and second cloprostenol administration for(More)
