Research ArticleOpen accessIn the keywordsComparison of in vitro Maturation Media on Cattle Oocytes after in vitro Embryo ProductionSindisiwe Mbali Sithole, Masindi Lottus Mphaphathi et al.The study was conducted to compare differences in vitro maturation media and their effect on subsequent in vitro embryo production. The study procedures were approved by the agricultural research council animal ethics committee (Ref no: APAEC 2020/05) and the Tshwane university of technology animal research ethics committee (Ref no: AREC 2021/08/004). Follicular fluid containing a suspension of oocytes was retrieved … …American Journal of Animal and Veterinary Sciences, Vol. 18, Issue 1 · 23 Feb 2023 · 6,912 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAugmentation of Temperatures, Media and Cryoprotectants on in vitro Fertilization of Pig OocytesTumelo Thelma Maduwa, Masindi Lottus Mphaphathi et al.There are numerous challenges to the large-scale production of pig embryos using in vitro procedures. The aim of the present study was to compare the different holding temperatures, in vitro maturation media, and permeating cryoprotectants in the in vitro fertilization of pig oocytes. Ovaries were obtained from the local slaughterhouse, oocytes were retrieved by means of aspiration and slicing techniques … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 3 · 29 Aug 2024 · 4,650 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffect of Fetal Serum and Follicular Liquor Supplementation on the In Vitro Production of Bovine EmbryosClara Larocca, Yael Filipiak, William Perez, Juan CalvoTo optimize In Vitro Fertilization (IVF) results in bovines by lowering costs, comparing the efficiency of Fetal Calf Serum (FCS) (high cost) with respect to bovine Follicular Fluid (bFF) (low cost) and by quantifying embryo production. Cumulus-Oocyte-Complexes (COC) obtained from a slaughter house, transported at 37°C in saline solution, were classified according to their quality in A, B, C and … …American Journal of Animal and Veterinary Sciences, Vol. 7, Issue 3 · 9 Aug 2012 · 7,839 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSynergistic Effect of Insulin on in vitro Development of Immature Bovine OocytesMojtaba Dashtizad, Abd Wahid Haron, Rosnina Yusoff et al.Problem statement: Development of efficient culture system to support embryonic development would be valuable when quality of produced embryos was important. However, the rate of bovine embryo production in vitro was still lower than expected. Present study, including of three experiments, was carried out to investigate the effect of insulin on nuclear maturation and subsequent development of immature bovine oocytes … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 4 · 31 Dec 2010 · 10,433 accessesView PDF Cite
