Research ArticleOpen accessIn the abstractUse of Cooled Bull Semen as a Strategy to Increase the Prenancy Rate in Fixed-Time Artificial Insemination Prgrams-Case ReportAndre Maciel Crespilho, Frederico Ozanam Papa, Marcos de Paula Santos, Manoel Francisco de Sa FilhoSemen cryopreservation is still considered suboptimal due to lower fertility when compared to fresh semen. The reasons for the loss of fertility are various and related to irreversible damage caused to the cells during the freeze-thaw process. An alternative to conventional cryopreservation represents the use of chilled bull semen, preventing the damage associated with freezing, thereby guaranteeing greater sperm viability. … …American Journal of Animal and Veterinary Sciences, Vol. 7, Issue 4 · 2 Feb 2013 · 8,681 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Heirloom Tomato Polyphenol Extracts on Expression of Inflammation Genes in BovineKwaku Gyenai, Nona Mikiashvili, Hamid Ismail, Mulumebet WorkuThe effect of tomato on diseases of economic importance continues to be of broad interest. To evaluate these relationships, the effect of crude extracts of Cherokee purple tomato on pro-inflammatory genes and cytokines were evaluated. Neutrophils from three Holstein Fresian cows were treated with Phosphate Buffered Saline (PBS) or E. coli O111-B4 Lipopolysaccharide (LPS). Treated cells were exposed to different … …American Journal of Animal and Veterinary Sciences, Vol. 7, Issue 3 · 25 Aug 2012 · 8,377 accessesView PDFCite
Research ArticleOpen accessIn the abstractEfficacy of Closantel 5% against Cattle Gastrointestinal ParasitesY. Garedaghi, A.P. Rezaii Saber, R. AttaremadrakiProblem statement: There are several anthelmintic classes based on chemical structure that are in use, but, during the last 20 years, it has been increasingly noted that the target parasites have become resistant, the incidence varying with geographical location and mode of use. Approach: In this study, 60 apparently healthy cows under the same management conditions of the experiment, feces … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 3 · 6 Oct 2011 · 8,200 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Cooling and Supplemental Bovine Somatotropin on Milk Production relating to Body Glucose Metabolism and Utilization of Glucose by the Mammary Gland in Crossbred Holstein CattleSiravit Sitprija, Somchai Chanpongsang, Narongsak ChaiyabutrProblem statement: The low milk yield and shorter persistency of lactation of dairy cattle is the major problem for the dairy practices in the tropics. High environmental temperatures and rapid decline of plasma growth hormone level can influence milk production. Regulation of the milk yield of animals is mainly based on the mechanisms governing the quantity of glucose extracted by … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 3 · 30 Sep 2010 · 7,341 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparison of Two Regimens of Nigella sativa Extract for Treatment of Subclinical Mastitis Caused by Staphylococcus aureusHamideh Ghodrati Azadi, Nima FarzanehProblem statement: Little research has focused on treatment of cows with subclinical mastitis during lactation. The seed of Nigella sativa Linn. (Ranunculaceae), commonly known as black seed or black cumin, is used in folk (herbal) medicine. Approach: Objectives of this study were to evaluate the effect of Nigella sativa Extract (NSE) with two regimens for treatment of subclinical mastitis in … …American Journal of Applied Sciences, Vol. 7, Issue 9 · 30 Sep 2010 · 7,742 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproving Performance of Replacement Heifers in Hot Arid Environment Under Intensive ManagementM. A. Razzaque, S. A. Mohammed, T. Al- Mutawa, M. BedairProblem statement: Imported Holstein Friesian dairy cattle are exposed to hot arid climate in feedlot management in Kuwait. Desert climate is extreme reaching high 45-50°C in summer and low -4ºC in winter at day and night respectively. High calf mortality, poor reproduction and milk yields were main constraints to viable dairying. The objectives of this study were to assess the … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 6,983 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of a DNA Vaccine for Immunocontraceptive Potential Against Zona Pellucida Glycoproteins in CattleC.A. Foley, S.M. Boyle, R.E. Pearson, F.C. GwazdauskasHolstein cows were administered zona pellucida (ZP) DNA vaccine and used to determine the potential of recombinant rabbit ZP glycoproteins (rZP) as immunocontraceptive antigens. Zona pellucida proteins were purified and quantified. Cows were assigned to one of four treatment groups in which plasmids encoding rabbit ZP proteins were administered, i.d., using a gene gun (ZP55, n=2; ZP75, n=2; Hep55, n=2; … …American Journal of Animal and Veterinary Sciences, Vol. 2, Issue 1 · 31 Mar 2007 · 6,888 accessesView PDFCite

Research ArticleOpen accessIn the abstractQuercetin Promotes the Expression of Genes Involved in Phagocytosis in Bovine NeutrophilsSuphakit Srikok, Sukij Nambut, Kanruethai Wongsawan, Phongsakorn ChuammitriThis study was conducted to explore the effect of Quercetin (QH) on phagocytosis of bovine neutrophils. Neutrophils were isolated from fifteen multiparous Holstein cows. We in vitro treated neutrophils with PBS or 50 µM of Quercetin (QH) or Cytochalasin B (CytB), as phagocytosis inhibitor, prior to monitoring phagocytosis of Escherichia coli by flow cytometry and microscopic examination. Additionally, the expressions … …American Journal of Animal and Veterinary Sciences, Vol. 12, Issue 2 · 2 Aug 2017 · 8,120 accessesView PDFCite
