Research ArticleOpen accessIn the abstractEffect of Different Rumen Undegraded Protein Level on Feed Consumption, Nutrient Digestion, Body Weight and Body Condition Score in Early Lactating Dairy CattleBudi Prasetyo Widyobroto, Rochijan, Fajar Satrio Pradana, Lies Mira YusiatiThe objective of this study was to determine effect of different rumen undegraded protein level on feed consumption, nutrient digestion, body weight and body condition score in early lactating dairy cattle. Ten Friesian Holstein cows were divided into two groups (five animals were used as control and another group as treatment object). Diets were forages and concentrates with ratio of … …OnLine Journal of Biological Sciences, Vol. 18, Issue 2 · 30 May 2018 · 7,692 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 abstractThe Effects of Subacute Ruminal Acidosis on Milk Fatty Acid Profile in Dairy CattleC. Mitchell, O. ALZahal, M.M. Or-Rashid et al.The objective of this experiment was to examine the effect of Subacute Ruminal Acidosis (SARA) on milk fatty acid (FA) profiles with emphasis on odd-chain and branched-chain FA. Sixteen multiparous Holstein dairy cows (618±35 kg of body weight, 221±32 days in milk) were used in a randomized complete-block design. During week 1, all cows received a high-forage diet (90% chopped … …American Journal of Animal and Veterinary Sciences, Vol. 11, Issue 2 · 27 Apr 2016 · 7,740 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Inclusion of Albizia saman Pods in the Diet on the Performances of Dairy CowsMin Aung, Yin Yin Kyawt, Moe Thida Htun et al.Ruminants can achieve high productivity when the diet includes concentrates; however these are often expensive due to competition with humans and mono-gastric animals. This experiment was conducted to determine the effect of partial inclusion of Albizia saman pods (ASP) in a Commercial Concentrate (CC) on the performances of dairy cows. Twelve cross-bred Holstein Friesian cows (472±13 kg) in the 12th … …American Journal of Animal and Veterinary Sciences, Vol. 11, Issue 1 · 29 Dec 2015 · 7,585 accessesView PDFCite
Research ArticleOpen accessIn the abstractTRANSCRIPTOMIC CHANGES IN RUMINAL TISSUE INDUCED BY THE PERIPARTURIENT TRANSITION IN DAIRY COWSLouis Dionissopoulos, Ousama AlZahal, Michael Alexander Steele et al.To understand how the capacity for fat metabolism (uptake, synthesis, modification) changes in rumen epithelia immediately before and after onset of lactation in dairy cows, rumen fluid Short Chain Fatty Acid (SCFA) concentrations and mRNA expression profiles of rumen epithelia was determined in twelve Holstein dairy cows at three weeks prior to calving (wk -3, n = 12), one week … …American Journal of Animal and Veterinary Sciences, Vol. 9, Issue 1 · 13 Jan 2014 · 7,501 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Rumen-Protected Methionine on Dairy Performance and Amino Acid Metabolism in Lactating CowsW.R. Yang, H. Sun, Q.Y. Wang et al.Problem statement: Free Met as one of the most limiting AA in dairy cows would be mostly degraded in the rumen. This study was to determine the effect of different levels of Rumen-Protected Met (RPMet) on dairy performance and serum amino acid metabolism. Approach: Thirty-six Holstein cows in similar condition were randomly assigned to six experimental treatments with six replicates … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 1 · 31 Jan 2010 · 8,262 accessesView PDFCite
Research ArticleOpen accessIn the abstractFirst Confirmed Case of Digital Dermatitis in GreeceP.D. Katsoulos, A. Minas, G. ChristodoulopoulosThe objective of the present study was to report the first confirmed case of digital dermatitis in Greece, emphasizing to the clinical appearance of the disease and to discuss some potential mechanisms concerning the entrance and the contagiousness of the disease in a new herd. The outbreak occurred in a new dairy farm of 60 primiparous Holstein cows in Thessaloniki … …American Journal of Animal and Veterinary Sciences, Vol. 3, Issue 2 · 30 Jun 2008 · 6,825 accessesView PDFCite
Research ArticleOpen accessIn the abstractPrevalence and Distribution of Mastitis Pathogens and their Resistance against Antimicrobial Agents in Dairy Cows in JordanAzmi D. Hawari, Fawzi Al-DabbasThe primary objective of this study was to determine the aetiology of bovine mastitis in ten herds of Holstein Friesian cow in Jordan, the prevalence of mastitis pathogens in dairy cows and their resistance to selected antimicrobial agents. Milk samples were collected from 220 lactating cows to determine the clinical and subclinical mastitis by white side test and confirmed by … …American Journal of Animal and Veterinary Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 7,675 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
