Reproductive efficiency of adult and prepubertal goats subjected to repeated follicular aspiration [ ABSTRACTThe objective of this study was to assess the reproductive response of adult and prepubertal goats subjected to repeated laparoscopic ovum pick-up (LOPU). The study animals were divided into two groups, specifically, adult nanny goats (GA, n=10) and prepubertal nanny goats (GP, n=10), which were subjected to estrous synchronization and ovarian stimulation for LOPU. Both groups underwent six LOPU procedures at seven-day intervals and were subsequently subjected to controlled mating and pregnancy diagnosis to evaluate their future fertility. The study showed a reduction in the number of follicles visualized and in the amount and quality of the oocytes that were recovered and exposed to in vitro maturation. As indicated by the fertility test, however, no complications were found during the laparoscopic procedures that would impair the reproductive future of the animals. Therefore, a viable number of oocytes were obtained even with the decreased reproductive efficiency, proving that repeated LOPUs do not interfere with the reproductive of adult and prepubertal nanny goats. These results indicate a positive aspect of this procedure, allowing for increasing reproductive performance of this kind, when used for the production in vitro.

“…It was observed that the percentage of oocytes from first dominant follicles that developed to blastocysts tended to decrease with increasing follicular diameter and estrous cycle days. Also, recovery of oocytes by transvaginal ultrasound-guided follicle aspiration once or twice a week for up to 12 weeks in heifers did not affect subsequent response to superovulation and embryo recovery or the occurrence of estrus [129]. Ooe et al [130] showed that ultrasound-guided transvaginal oocyte aspiration can be performed repeatedly and safely at different phases of the estrous cycle and stages of gestation in pregnant cows.…”

Abstract. The advent of ultrasonography over a decade ago has contributed tremendously in the field of bovine reproduction. Ultrasound imaging has shown that cattle exhibit 2 or 3 waves of follicular development during an estrous cycle. Ultrasonography allows monitoring of individual follicles as they grow and/or regress over time and patterns of follicular development can thus be determined with relative precision. Other important applications of ultrasonography in bovine reproduction includes; pregnancy diagnosis, fetal sex determination, folliculocenteses, diagnosis of abnormalities of the reproductive organs, monitoring of treatment of ovarian cysts, monitoring of postpartum genital resumption, ultrasound-guided centesis and male genital ultrasonography. Recent applications of ultrasonography in bovine reproduction includes doppler ultrasonography for genital blood flow and mammary ultrasonography. The use of ultrasonography is indispensable in most studies in which morphology (structure) and function are correlated. In this paper, the literature pertaining to the use of ultrasonography in bovine reproduction is reviewed. The applications and limitations of ultrasonography are highlighted. The non-invasive nature of ultrasonography makes it an excellent clinical and research tool in bovine reproduction.

“…An unexplored option for repeated oocyte collection from the sow can be transvaginal ultrasound-guided aspiration procedure (TUGA), which has proven repeatable and efficacious for recovering oocytes for IVP of embryos in domestic ruminant animals. TUGA has been extensively tested in cattle; cycling cows beef [13,16,18] dairy [4,6,33], pregnant cows [23], post-partum cows [27,28], pre-pubertal calves [7,9,30] and cows with reproductive problems [15,20]. The procedure has also been used in oocyte production in the cyclic mare [10,11,14] and pregnant mares [22], the goat [17], zebra [24], swamp buffalo [26], llama [8] and hoof-stock [21].…”

ABSTRACT. A procedure developed for nonsurgical transvaginal ultrasound-guided oocyte aspiration in the mature sow was dependent upon development of a special chute. This chute was designed to immobilize and protect the sow. The floor of the chute possessed a metal bar that was elevated via a hydraulic lift until the weight of the sow rested on the bar, while her hooves were still in contact with the floor. This exact positioning of the female prevented her from resisting procedure and allowed for a comfortable setting for technician to manipulate the ovaries (per rectum) and perform transvaginal ultrasound guided oocyte aspiration (TUGA). Oocyte collection was performed in six sows, and none experienced detrimental health effects from the procedure.
