Research ArticleOpen accessIn the keywordsSuperovulation 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 keywordsImproving the Technology for Assessing the Semen of Beige Karakul SheepAigerim Turekyzy Bigarayeva, Nuradin Alibayev, Arkadiy Kanurovich Natyrov et al.The article presents the research results on the effective use of seed products from breeding rams in reproduction for the conservation and targeted propagation of genetic resources of Karakul sheep of rare beige color, which are on the verge of extinction. Selected freshly obtained ejaculates from 6 beige rams of the Karakul breed in the amount of 32 samples, meeting … …OnLine Journal of Biological Sciences, Vol. 25, Issue 1 · 17 Feb 2025 · 4,501 accessesView PDFCite
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 abstractQuality of Sperm Simmental Bulls and Success of Artificial Insemination with the Addition of Nanocalcium Phosphate in Tris Aminomethane Egg Yolk Diluent Using Semen Storage Ampoules from Nanocalcium Silicophosphate BiomaterialsEnike Dwi Kusumawati, I Wayan Karyasa, Yogi Pratama Putra et al.Success in Artificial Insemination (AI) is largely determined by the quality of the stored semen, therefore storage devices, especially straws or ampoules, are an important part that cannot be separated from the overall semen cryopreservation technology. Making a prototype of semen storage ampoules from nanocalcium silicophosphate biomaterials is based on the need for straws or ampoules. Semen storage in spermatozoa … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 2 · 28 May 2024 · 5,211 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 abstractFrozen Semen Quality of Kolbroek Boars Concerning Glutathione ConcentrationsLerato Deirdre Sehlabela, Masindi Lottus Mphaphathi et al.Glutathione (GSH) is an antioxidant that is being studied for its ability to improvecellular responses to semen preservation challenges. The research goal aimed toevaluate the impact of introducing different glutathioneconcentrations to boar semen freezing extender (0, 1, 5, and 10 mM) onthe Kolbroek boar sperm's quality after being frozen and thawed. For 2 h, thecollected sperm-rich fraction was chilled at … …American Journal of Animal and Veterinary Sciences, Vol. 18, Issue 1 · 1 Apr 2023 · 6,005 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssociation Between Climatic Factors with Fresh Semen Quality Parameters in Madura Cattle (an Indonesian Native Breed)Nurul Isnaini, Bela Dwi Wadi Lestari, Faizal Andri et al.Semen quality is a critical point to ensure the success of the artificial insemination program. One factor which highly determine the semen quality of bulls is climatic conditions. The purpose of the present study was to evaluate the association between climatic factors and fresh semen quality parameters in Madura bulls. A total of 1583 ejaculates which were collected from 5 … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 3 · 15 Sep 2021 · 6,810 accessesView PDFCite
Research ArticleOpen accessIn the abstractSeasonal Variations in Semen Quality of Pasundan Bulls in their Native Tropical EnvironmentNurul Isnaini, Tri Harsi, Anggit Damaratri Lapoliwa et al.The success of artificial insemination highly depends on the semen quality, in which it may significantly associate with the environmental factor. However, the information regarding the seasonal effects on semen quality of Pasundan bulls is still scarce. This study aimed to examine seasonal variation in semen quality of Pasundan bulls in their native environment. A total of 203 ejaculates produced … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 2 · 27 Apr 2021 · 7,931 accessesView PDFCite
