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 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 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
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 abstractStudy the Effect of Extracted Low-Density Lipoprotein from Egg Yolk on the Cryopreservation of Nguni Bull SemenMduduzi M. Tshabalala, Masindi Lottus Mphaphathi, Khathutshedzo A. Nephawe et al.The mechanism on how Egg Yolk (EY) helps sperm to survive the low temperature outside the animal body during cryopreservation and thawing process is not yet known. It is usually believed that the Low-Density Lipoprotein (LDL) is the major component that provides protection. The present study was undertaken to assess the cryo-protective effect of different concentrations (6, 8, 10 and … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 3 · 13 Sep 2021 · 6,915 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Repeated Freezing and Thawing on Nguni Sperm Parameters Evaluated by Computer Assisted Sperm Analyzer SystemMasindi Lottus Mphaphathi, Tshimangadzo Lucky NedambaleThe aims of the current study were to assess the effect of double freezing and thawing on Nguni semen parameters. Semen was collected from Nguni bulls. The Sperm Class Analyzer® system was used to evaluate sperm motility rates prior and post freezing, repeatedly. Semen samples were diluted with egg yolk citrate extender. Cooled semen samples were loaded into straws and … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 1 · 27 Jan 2021 · 6,591 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Complete Feed Silage Made from Agricultural Waste on Milk Yield and Quality of Dairy CowsAmbo Ako, Syahdar Baba, Fatma et al.The problem facing dairy cow producers in tropical area is the low availability of proper nutrition, especially during the dry season. One solution to overcome this problem is to utilize technology of Complete Feed (CF) silage using ensiled several local abundant ingredients from agricultural wastes. This study aimed to find a formulation of CF silage from agricultural wastes as forage … …OnLine Journal of Biological Sciences, Vol. 16, Issue 4 · 17 Nov 2016 · 7,502 accessesView PDFCite
Research ArticleOpen accessIn the abstractUse of Quinolones in Bull Semen Extenders to Reduce Sperm Deoxyribonucleic Acid DamageClara Gonzalez-Marin, Michael Eduard Kjelland, Rosa Roy et al.Cryopreserved sperm samples from Holstein bulls (n = 20) were examined for bacterial presence and Sperm DNA Fragmentation (SDF) dynamics. SDF was assessed after thawing (T0) and at 4, 24 and 48 h of incubation (37°C) and the rate of SDF (r-SDF), as an estimator of the DNA degradation over time, was calculated. Two groups of bulls were identified based … …American Journal of Animal and Veterinary Sciences, Vol. 7, Issue 4 · 29 Dec 2012 · 7,430 accessesView PDFCite
