Research ArticleOpen accessEvery word in the titleCorrelation of Oxytocin (OTR) and Estrogen Receptor (ER) mRNA in the Canine Placenta with the Detected Circulating Levels of Oxytocin and Estrogen during Pregnancy and ParturitionGisele Almeida Lima Veiga, Marcella Pecora Milazzotto, Marcilio Nichi et al.Placenta is considered an important endocrine organ during gestation, as well as can also serve as a target organ for sex steroids and pituitary hormones, mainly for the cascade of events that trigger parturition. In order to initiate studies on the canine placental endocrinology regarding estrogen and oxytocin, the present study verified the correlation among the Estrogen Receptor alpha (ERα) … …American Journal of Animal and Veterinary Sciences, Vol. 11, Issue 1 · 31 Dec 2015 · 8,272 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsTRANSCRIPTOMIC 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 PDF Cite

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 PDF Cite

Research ArticleOpen accessIn the abstractSerum Ornithine Carbamoyltransferase Activity and Correlation with Fatty Liver in Dairy Cows with Displaced AbomasumKen Onda, Reiichiro Sato, Yosuke Sasaki et al.Ornithine Carbamoyltransferase (OCT) is a hepatocyte-specific enzyme; elevated serum activity indicates liver damage. Displaced abomasum frequently occurs around the time of parturition in dairy cattle and is associated with fatty liver. We analyzed serum OCT activities to investigate the relationship between displaced abomasum and fatty liver. Lactating Holstein cows, 75 clinically healthy and 22 with displaced abomasum, were used. Serum … …American Journal of Animal and Veterinary Sciences, Vol. 11, Issue 3 · 13 Jul 2016 · 7,660 accessesView PDF Cite

Research ArticleOpen accessIn the abstractChanges in the Rumen Papillae During the Periparturient Transition in Holstein Dairy Cows are Accompanied by Changes in Abundance of Proteins Involved in Intracellular pH Regulation, But not SCFA TransportAnne Hermen Laarman, Adam Kleinberg, Michael Alexander Steele et al.The objective of this study was to examine changes in SCFA transport capacity in the rumen epithelium during the parturition transition period. Twelve pregnant, cannulated primiparous and multiparous cows were fed a standard Total Mixed Ration (TMR) for the duration of the dry period; after calving, all cows were switched to an early lactation TMR. Rumen pH, fluid and biopsies … …American Journal of Animal and Veterinary Sciences, Vol. 10, Issue 1 · 31 Mar 2015 · 7,546 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNUTRITIONAL CHARACTERISTICS OF THE DAIRY COW DURING EARLY GESTATION AND SUBSEQUENT GROWTH AND CARDIAC MEASUREMENTS OF HER OFFSPRINGJ. E. Larson, B. E. Voelz, D. K. Hardin, C. O. LemleyThe objective was to determine whether maternal nutritional status and milk production during early gestation influenced or were correlated with parameters of the calf at birth and at 1 month of age. From parturition until 90 days pregnant, blood samples were collected every 14 days in dairy cows and plasma was assayed for concentrations of glucose and β-Hydroxybutyrate (BHBA). Calves … …American Journal of Animal and Veterinary Sciences, Vol. 9, Issue 3 · 15 Sep 2014 · 7,625 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEFFECT OF DIMETHOATE (AN ORGANOPHOSPHATE INSECTICIDE) ON THE REPRODUCTIVE SYSTEM AND FERTILITY OF ADULT MALE RATFerdinand Ngoula, Pierre Watcho, Augustave Kenfack et al.The pesticides are one of the most potentially harmful chemicals liberated in the environment in an unplanned manner. Dimethoate is widely used as a potent pesticide in many countries and has been shown to produce some adverse health effects. In the present study, we investigated the effect of dimethoate (an organophosphate insecticide) on the reproductive system and fertility of male … …American Journal of Pharmacology and Toxicology, Vol. 9, Issue 1 · 13 Feb 2014 · 8,595 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Effect of Rumen Acid Load on Postpartum Performance and Blood Metabolic Responses in Transition Holstein CowsSadjad Danesh Mesgaran, Alireza Vakili, Alireza Heravi Moosavi, Ghasem KoolabadiProblem statement: The transition period is the most stressful time in the production cycle of a dairy cow because of depressed feed intake, endocrine and metabolic changes at parturition. The aim was to determine the effect of rumen acid load on postpartum performance and metabolic parameters in transition Holstein cows. Approach: The Acidogenicity Values (AV) of the diets were determined … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 1 · 25 May 2011 · 7,438 accessesView PDF Cite
