Research ArticleOpen accessIn the abstractSupplementation with Different Concentrations of Dithiothreitol and Glutathione During Cryopreservation of Semen from Large White BoarsMahlatsana Ramaesela Ledwaba, Masindi Lottus Mphaphathi et al.The study aims to compare different concentrations (0, 2.5, 5, 7.5 and 10 mM) of antioxidants, Dithiothreitol (DTT) and Glutathione (GSH), on sperm parameters following the freeze-thawing of semen from large white boars. Three large white boars were selected for semen collection and the collected semen was sent to the lab for analysis. Following dilution with Beltsville thawing solution and … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 3 · 3 Jun 2024 · 5,517 accessesView PDF Cite

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 PDF Cite

Research ArticleOpen accessIn the abstractEvaluation of Japanese Quail Egg-Yolk Extender in Cryopreservation of Cockerel SemenRantloko Rolly Maapola, Khathutshelo Agree Nephawe, Tshimangadzo Lucky Nedambale et al.The purpose of this study was to examine the effects of quail egg yolk extenders in the cryopreservation of cockerel semen. Ten Venda cockerels were chosen randomly and semen was collected twice a week with a two-day rest period using an abdominal massage technique. Immediately following semen collection, semen samples were evaluated for microscopic parameters (sperm cell motility, viability, morphology, … …American Journal of Animal and Veterinary Sciences, Vol. 18, Issue 1 · 25 Mar 2023 · 5,638 accessesView PDF Cite

Research ArticleOpen accessIn the abstractInfluence of Intracellular Reactive Oxygen Species in Several Spermatozoa Activity in Indonesian Ongole Bull Cryopreserved SpermKurniawan Dwi Prihantoko, Asmarani Kusumawati, Mulyoto Pangestu et al.Certain factors may affect sperm motility and integrity in a freezing process. Reactive Oxygen Species (ROS) is essential in damaging the sperm, as the previous study revealed that ROS is a major cause damaging the membrane of spermatozoa. This study aimed to understand ROS production and its interaction within the motility, mitochondrial activity and DNA damage to the cryopreservation process … …American Journal of Animal and Veterinary Sciences, Vol. 17, Issue 1 · 26 Jan 2022 · 6,842 accessesView PDF Cite

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 PDF Cite

Review ArticleOpen accessIn the abstractThe Influence of Bedding Application in Feedlot Cattle: A ReviewDathan Thomas Smerchek, Zachary Kidd Foster SmithA sizable portion of cattle on feed in the United States are fed in the Upper Midwest and Northern Plains region where temperatures routinely fall below freezing during late fall, winter and early spring. The persistent cold temperatures coupled with snow accumulation, wind, moisture and ice can cause undesirable pen conditions for confined cattle, ultimately resulting in decreased insulative capacity … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 1 · 23 Feb 2021 · 6,718 accessesView PDF Cite
