Research ArticleOpen accessIn the abstractEffect of Semen on the Embryo Productivity of Donor Cows and the Development of Transplant CalvesBolatbek Ateikhan, Toktar Karibaevich Bexeitov, Talgat Kozybakovich Seiteuov et al.In animal husbandry, more heifers are requiredfor the expanded reproduction of the herd or milk, and more bulls are needed toobtain meat. One of the effective ways to artificially regulate the secondary(at birth) sex ratio is the technology of sexed semen. In this connection, thepurpose of this study was to study the effect of sexed and native semen on theembryonic … …OnLine Journal of Biological Sciences, Vol. 22, Issue 3 · 6 Sep 2022 · 5,430 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

The effectiveness of male sex assignment or female sex reassignment as a treatment for aphallia has been debated. The study's goal was to address the gonadal existence and supporting investigation related to the reproductive health care of reported cases of aphallia patients such as karyotyping, physical examination, … …OnLine Journal of Biological Sciences, Vol. 22, Issue 2 · 25 May 2022 · 6,304 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 abstractBiotic and Abiotic Factors of Sperm nDNA Fragmentation in Farm AnimalsBaylar Iolchiev, Natalya Volkova, Pavel Klenovitskiy et al.Infertility and subfertility are among the global challenges of our time. Fertility in livestock farming is not only biologically important, it is also economically important. The aim of this study was to study the effect of these factors on sperm chromatin nucleus and to assess the impact of the fragmentation index degree on bull reproductive performance. The influence of abiotic … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 1 · 11 Mar 2021 · 6,714 accessesView PDFCite
Research ArticleOpen accessIn the abstractGenotype Screening of Bovine Brachyspina in Taiwan Holstein CowsChun Hsuan Chao, Yi Ming Chen, Kuo Hua LeeThis study analyzed carrier frequencies of the genetic defect bovine brachyspina (BS) in the Holstein cows in Taiwan. In total, 1688 cows from 31 herds were included in the analysis, performed using the Igenity-Prime 50K single-nucleotide polymorphism chip. Of the 1688 cows, 68 (5.09%) were BS carriers (BY), a frequency lower than that reported in Taiwan previously.

Research ArticleOpen accessIn the abstractOligoasthenoteratozoospermia and Necrozoospermia: A Study of Sperm Na+, K+-ATPase α4 and Plasma Membrane Ca2+-ATPase 4 RegulationSilvia W. Lestari, Dessy Noor Miati, AsmarinahThe oligoasthenoteratozoospermia (OAT) and necrozoospermia are the extreme sperm abnormalities in male infertility. These sperm abnormalities may be related to the imbalance of ion transport which mediated by the ion-transporting P-type ATPases, such as Na+, K+-ATPase and Ca2+-ATPase. Until now, there is limited data about the activity of Na+, K+-ATPase and Ca2+-ATPase in sperms in the OAT and necrozoospermia samples. … …OnLine Journal of Biological Sciences, Vol. 18, Issue 3 · 3 Aug 2018 · 11,269 accessesView PDFCite
