Research ArticleOpen accessIn the keywordsEffect of the Strategic Supplementation for Producing Embryos of Native Hartón del Valle HeifersAdrian Rolando Riascos-Vallejos, Julio Jesus Reyes-González, Yolaine Medina-Mesa, Juan Pablo Narvaez-HerreraNutritional imbalances have been confirmed in other breeds, related to energy, proteins and minerals and this affects embryonic development, production of quality. In this regard, the objective of this research was to evaluate the effect of strategic supplementation for the production of embryos in native Hartón del Valle heifers. For that purpose, 18 pure heifers were used, fed with a … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 1 · 7 Mar 2021 · 6,618 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSynergistic 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 PDFCite
Research ArticleOpen accessIn the abstractEffect of Temperature Change and Estradiol Levels on Cattle Oocytes Developmental Competency: Comparing X-Sexed and Non-Sexed Sperm Following in vitro FertilizationMaleke Dimpho Sebopela, Masindi Lottus Mphaphathi et al.The study aimed to investigate the effects of temperature change and estradiol (E2) hormone level on In Vitro Maturation (IVM) and fertilization of cattle oocytes using X-sexed and non-sexed sperm. In experiment 1: The oocytes were incubated at various temperatures of 35.5, 36.5, 37.5, 38.5, 39.5 and 40.5°C under similar conditions with 5% CO2, in humidified air for 22 h. … …American Journal of Animal and Veterinary Sciences, Vol. 18, Issue 4 · 16 Nov 2023 · 5,319 accessesView PDFCite
Research ArticleOpen accessIn the abstractFSH Receptor and Ki-67 Protein Expressions of Endometrial Macaque in Mid-Luteal Phase after Exposure to Various Doses of Recombinant FSH and Fixed-Dose of GnRH AgonistNurhuda Sahar, Ponco Birowo, Rosalina Thuffi et al.There are many advances in Assisted Reproductive Technologies (ARTs). However, implantation rates are still low. The embryo implantation is a mutual interaction between the blastocyst and endometrium. This study aimed to investigate the endometrial cell proliferation stimulated by recombinant Follicle-Stimulating Hormone (rFSH) in various doses by looking at FSH-Receptor (FSHR) and Ki-67 protein expressions. The studied samples were Stored Biological … …OnLine Journal of Biological Sciences, Vol. 21, Issue 2 · 28 May 2021 · 6,347 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Equilibration Temperature on In vitro Viability and Subsequent Embryo Development of Vitrified-Warmed Immature Bovine OocytesHajarian Hadi, H. Wahid, O. Abas Mazni et al.Problem statement: Vitrification is replacing conventional slow freezing to cryopreserve gametes and embryos especially for in vitro production of embryo in domestic animal species. However, the results are still not satisfactory. The aim of this experiment was to study the effect of different equilibration temperatures on in vitro viability of immature bovine oocytes after vitrification. Approach: Oocytes were obtained from … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 2 · 1 Sep 2010 · 16,116 accessesView PDFCite
