Review ArticleOpen accessIn the abstractGenomic Regions and Candidate Genes Associated With Semen Traits in Rams: A Systematic GWAS Review With Implications for South African Sheep BreedsNhlakanipho Sam Zulu, Khoboso Christine LehloenyaRam fertility is a key determinant of reproductive efficiency in sheep production systems, particularly under extensive and semi-extensive conditions prevalent in South Africa. Semen quality traits, including ejaculate volume, sperm concentration, motility, and cryotolerance, exhibit measurable genetic variation and are increasingly investigated using genomic approaches. This systematic review synthesizes evidence from three eligible Genome-Wide Association Studies (GWAS) analyses that have … …American Journal of Animal and Veterinary Sciences, Vol. 21, Issue 3 · 26 Oct 2026 · 50 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimalization of the Swim-Up Method for Bali Bull Sperm: Effect of Incubation Time and Medium on Sperm KineticsAthhar Manabi Diansyah, Muhammad Yusuf, Rahmat et al.Bali bulls (Bos javanicus) are an essential part of Indonesia’s indigenous livestock, prized for their ability to thrive in challenging environments, their natural disease resistance, and their strong reproductive capabilities. The aim of this study was to refine the swim-up technique for preparing Bali cattle sperm. We evaluated the effects of two commonly used media Tyrode's Albumin Lactate Pyruvate (TALP) … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 4 · 9 Feb 2026 · 1,687 accessesView PDFCite
Research ArticleOpen accessIn the abstractIn vitro Kinematics Semen Tolerance to Oxidative StressCyril Mpho PilaneInterpretation of semen kinematic parameters remain as a point of discussion in predicting semen quality following processes like cryopreservation. During cryopreservation, oxidative stress remains a challenge in promoting post-thaw semen quality. Comparison of livestock semen exposed to oxidative stress, in vitro, highlight various aspects of sperm cell movement, like kinematics, to predict their qualities. Sperm cell kinematics includes the measurement … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 3 · 13 Sep 2024 · 4,560 accessesView PDFCite
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 PDFCite
Research ArticleOpen accessIn the abstractTestosterone Concentration, Libido and Spermatozoa Quality in Gembrong Goats after in vivo and in vitro PGF2α AdministrationHusnurrizal, Sri Wahyuni et al.The Gembrong goat population is currently in a critical state. The preliminary study results show that one of the factors causing the population decline is the low fertility of male goats characterized by low sperm quality. The improvement of the spermatozoa quality can be performed with the administration of PGF2α. This study aims to determine the difference in semen quality … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 2 · 29 Apr 2024 · 5,541 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Increase of Madura Cows Reproduction Performance with Double-Dose Method of Artificial InseminationKuswati, Wike Andre Septian, Khairul Rasyad et al.One of the potencies of Madura cow genetics is its adaptation ability to the tropical climate. Yet in most cases, the reproduction efficiency of the Madura cows has not reached the optimum point. This research examines the use of double-dose artificial insemination compared to a single-dose on Madura cows. The study was conducted in Daramista, Lenteng District, Sumenep Regency, Madura, … …American Journal of Animal and Veterinary Sciences, Vol. 17, Issue 3 · 2 Aug 2022 · 6,163 accessesView PDFCite

Mphaphathi, Edward C. Webb, Ayanda MaqhashuThe objectives of the study were to: Compare oocyte retrieval methods (aspiration and slicing) from pig ovaries on oocyte quality and quantity; compare in vitro maturation (IVM) media (North Carolina State University -NCSU 37; Tissue Culture Medium-TCM 199; and porcine follicular fluid-mpFF) on oocytes polar body extrusion; compare the effect of Electrical Stimulation (ES) and frozen-thawed semen on cleavage rates … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 4 · 5 Jan 2022 · 6,600 accessesView PDFCite
Research ArticleOpen accessIn the abstractSuperovulation Response and Embryo Quality Recovered Following Flushing Nguni Heifers and CowsAyanda Maqhashu, Masindi L. Mphaphathi, Pokgedi J Sebei et al.The aims of the study were to compare super ovulatory response, fertilization rate and evaluate embryo quality recovered from super ovulated Nguni stud cows and heifers. Nguni cows (n = 15) and heifers (n = 10) aged 4-6 and 2 years, respectively, were used as embryo donors. Embryo donors were synchronized for estrus before superovulation. For superovulation donors were administered … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 4 · 25 Nov 2021 · 6,431 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of the Tensioactive Agent SDS on Extender’s Boar Semen Viability after ThawingMaria Helena Moreira da Silva, Loide Valadão, Fernando Moreira da SilvaEffects of the surfactant Sodium Dodecyl Sulfate (SDS) on the motility and viability of boar semen after thawing were evaluated. For such purpose, semen of twelve adult boars was collected twice a week, the rich portion of this semen was separated and frozen with different concentrations of SDS (0; 2.5; 5; 10; 20 and 40 mM). For freezing the semen … …American Journal of Applied Sciences, Vol. 18, Issue 1 · 20 Jan 2021 · 7,795 accessesView PDFCite
