Research ArticleOpen accessIn the keywordsThe 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 abstractSemen Quality and Artificial Insemination Efficacy Using Sericin-Silica-Phosphate-CuO Hydrogel in Thin-tailed SheepEnike Dwi Kusumawati, I Wayan Karyasa, Duran Corebima Aloysius et al.Artificial Insemination (AI) in livestock is increasingly demanded because it greatly affects the productivity and quality of livestock. AI should be supported by advanced material chemistry, especially organic-inorganic hybrid biomaterials. We aimed to produce a prototype of renewable advanced biomaterial technology in the form of Sericin-Silica-Phosphate (SER-SI-PO) hydrogel reinforced with Copper Nanoparticles (CuNPs) and its application in AI. The testing … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 2 · 10 Jun 2025 · 3,851 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Use of Management and Hormonal Oestrous Synchronisation on Indigenous Sheep Reared ExtensivelyAyanda Maqhashu, Jabulani Nkululeko Ngcobo, Hester Adri O'Neill et al.As the global population increases, demand for animal products will result in increased livestock-related greenhouse gas emissions that contribute to climate change. One of the strategies for reducing this impact would be the improvement of indigenous livestock reproductive efficiency that are hardy and well adapted to harsh environmental regions. The use of reproductive technologies increases efficiency of animals necessary for … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 3 · 29 Aug 2024 · 4,778 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Comparative Study on the Reproductive Performance of South African Indigenous Sheep Breeds Following Oestrus SynchronizationJabulani Nkululeko Ngcobo, Tshimangadzo Lucky Nedambale, Tlou Caswell Chokoe, Fhulufhelo Vincent RamukhithiThe aim of the study was to compare the effect of age and live body weight on the oestrus response, duration, pregnancy rate and lambing rate among South African indigenous sheep breeds (Zulu sheep = 36, Bapedi sheep = 26, Damara sheep = 10 and Namaqua Afrikaner sheep = 9). Control Intravaginal Drug Release Dispensers (CIDR’s) were inserted into the … …American Journal of Animal and Veterinary Sciences, Vol. 17, Issue 1 · 14 Jan 2022 · 7,862 accessesView PDFCite
Research ArticleOpen accessIn the abstractβ-carotene Supplementation Increases Progesterone Concentration and Glutathione Peroxidase Activity Following Alternative Progesterone Primed Oestrous Synchronization Protocol in GoatsDominic Lado Marino Gore, Khoboso Christina LehloenyaThe present study evaluated the effect of β-carotene supplementation and oestrous synchronization protocol on ovarian activity and fertility of Saanen does during the breeding season. The supplemented group received 100 mg β-carotene during the breeding and all does were synchronised with Controlled Internal Drug Release dispenser (CIDR) and injected with cloprostenol at CIDR withdrawal. One group of does were injected … …American Journal of Animal and Veterinary Sciences, Vol. 15, Issue 3 · 8 Aug 2020 · 6,896 accessesView PDFCite
EditorialOpen accessIn the abstractAn Opportunity for the Agricultural Sector: The Renewable Energy SourcesRiccardo Testa, Salvatore TudiscaToday, among the most important issue for energy decisions by policymakers, there are security challenges and environmental impacts on climate change and economic aspects. Since the seventies, in fact, global warming and environmental issues have had an increasing importance in international debate, attracting the attention of several scientific studies (Landi and Benelli, 2016). Many of these studies denoted that over … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 3 · 6 Sep 2016 · 8,092 accessesView PDFCite
Research ArticleOpen accessIn the abstractTreatment of Ovarian Inactivity in Mares During the Breeding Season with PMSG/hCG, PMSG or GnRH and the Effect of Treatment on Estradiol and Progesterone ConcentrationsMohamed Sabry Medan, Taher Al-DaekThe objective of the present study was to treat ovarian inactivity in mares during the breeding season by using three protocols. Mares (n = 52) kept under field condition in the Green Mountain area, north of Libya were examined transrectally by ultrasound during the breeding season. They were assigned to have inactive ovaries which was confirmed by measuring serum estradiol … …American Journal of Animal and Veterinary Sciences, Vol. 9, Issue 4 · 13 Dec 2014 · 7,562 accessesView PDFCite
Research ArticleOpen accessIn the abstractEFFECT OF PUERPERAL METRITIS ON HOLSTEIN COWS PRODUCTIVE, REPRODUCTIVE VARIABLES AND CULLING RATESA. Dawod, Byeng R. MinThe objective of the study was to determine the effect of puerperal metritis prevalence in high yielding Holstein cows on productive (305 days, actual milk yields), reproductive (days to first estrus, days open and services per conception) variables and culling rates.
