Effect Of Intravenous Treatment With The Oxytocin Antagonist Atosiban On Circulating Progesterone In The Ewe, Todd M. Ramboldt
Effect Of Intravenous Treatment With The Oxytocin Antagonist Atosiban On Circulating Progesterone In The Ewe, Todd M. Ramboldt
Graduate Theses, Dissertations, and Problem Reports
Effects of oxytocin on the ovine corpus luteum have been controversial for a number of years. The present study investigated the effects of atosiban, a combined oxytocin and vasopressin 1A antagonist, administered systemically to ewes on post estrus day 8 to 10. Atosiban was given in four bolus intravenous injections at 0, 60, 120 and 180 minutes with blood sampling every 15 minutes from -60 through 480 minutes. Concentrations of serum progesterone ng/ml were measured via radioimmunoassay. A log10 transformation of progesterone values was conducted to account for the heterogeneity of variance of the values. During the treatment interval (0 …
The Effect Of Conjugated Linoleic Acid (Cla) On Feed Efficiency And Carcass Composition In Barrows, Natasha R. Winslow
The Effect Of Conjugated Linoleic Acid (Cla) On Feed Efficiency And Carcass Composition In Barrows, Natasha R. Winslow
Graduate Theses, Dissertations, and Problem Reports
The purpose of this study was to determine if conjugated linoleic acid (CLA) would have an effect on feeding efficiency and carcass composition of 20 finishing barrows obtained from the West Virginia University Animal Science Farm. A posttest experimental design was used to obtain data for the study. The barrows were matched for weight and placed two in a pen. The pens were randomly assigned to a diet consisting of either a 1% CLA oil or 1% soybean oil. The six week study found that weight gain, average daily feed intake, muscle lipids, loin eye area, and color were not …
The Effects Of Genetic Strain And Finisher Diet Non-Phytate Phosphorus Level On Performance, Lysine Degradation And Litter Composition Of Large Tom Turkeys, Brittany Nicholle Swiger
The Effects Of Genetic Strain And Finisher Diet Non-Phytate Phosphorus Level On Performance, Lysine Degradation And Litter Composition Of Large Tom Turkeys, Brittany Nicholle Swiger
Graduate Theses, Dissertations, and Problem Reports
Successful commercial turkey production requires proper genetic strain selection to optimize live performance and profit. In addition, sustainable practices relative to manure disposal are essential due to perceptions that land application of poultry manure is a primary contributor to watershed eutrophication. The objective of our research was to assess genetic strain and finisher diet non-phytate phosphorus (nPP) level effects on large tom performance and litter composition using a research facility that mimics commercial production. Experiments were 2x2 factorial designs utilizing 2 strains (Nicholas and Hybrid) and 2 levels of dietary nPP (normal and low) in finishing diets. Two experiments of …
Effects Of Resveratrol Supplementation On Glycemic Response And Oxidant Status In Moderately Exercised Mature Quarter Horse Geldings, Jennie L. Zambito
Effects Of Resveratrol Supplementation On Glycemic Response And Oxidant Status In Moderately Exercised Mature Quarter Horse Geldings, Jennie L. Zambito
Graduate Theses, Dissertations, and Problem Reports
Resveratrol, a naturally occurring phytocompound is known to exert numerous health benefits including improved insulin sensitivity and glucose tolerance, along with decreased tissue damage due to reactive oxygen species (ROS). This compound is incorporated in a multitude of supplements targeted to performance horses, yet no research in an athletic equine model has been completed to date. Therefore, this study was performed to test the hypothesis that resveratrol supplementation would improve glucose tolerance and insulin sensitivity, while reducing oxidant damage in an exercising model. Six, healthy, fit aged (10.5+/-1.5yr, ~500kg) Quarter Horse geldings were assigned to three treatment groups in a …
Characterizing Textural Attributes Of Rainbow Trout, Oncorhynchus Mykiss, Fillets As Affected By Age, Sterility, And Storage Regimen, Aunchalee Aussanasuwannakul
Characterizing Textural Attributes Of Rainbow Trout, Oncorhynchus Mykiss, Fillets As Affected By Age, Sterility, And Storage Regimen, Aunchalee Aussanasuwannakul
Graduate Theses, Dissertations, and Problem Reports
Trout fillets, subjected to refrigeration (4°C; 3 or 7 d) by frozen storage (-25°C; 0 or 30 d) combinations, were cooked; texture, determined by a novel, variable-blade (VB) attachment, was compared with a widely-used Allo-Kramer shear (AK) attachment to determined its sensitivity in detecting variation in fillet texture. Instrumental texture was related to sensory measurements to determine attachments' accuracy in assessing cooked fillet texture. Weight of raw fillets decreased after 30-d frozen storage. Fillet weight further decreased after cooking. Moisture content decreased while fat content remained constant. The AK attachment detected differences in energy of shear, which decreased after 30-d …
Effect Of Service Sire On Late Embryonic And Fetal Loss In Sheep, Tammy L. Holler
Effect Of Service Sire On Late Embryonic And Fetal Loss In Sheep, Tammy L. Holler
Graduate Theses, Dissertations, and Problem Reports
Very few authors have studied the effect of the sire on the outcome of pregnancy in sheep beyond differentiation, development, spermatogenesis, fertilization and early embryo survival. A major limitation in direct selection for increased sire competence is that males need to be selected mainly on the performance of their female relatives and females do not express lambing traits until at least one or two years of age. This selection process can be accelerated by studying prenatal survival ability of individual ram's progeny.;The objective of the present study was to identify occurrence of late embryonic and fetal mortality in relation to …
Diet Induced Alterations And Distribution Of Indices Of Lysine Catabolism, Stephanie K. Gatrell
Diet Induced Alterations And Distribution Of Indices Of Lysine Catabolism, Stephanie K. Gatrell
Graduate Theses, Dissertations, and Problem Reports
Lysine is thought to be oxidized primarily by lysine alpha-ketoglutarate reductase (LKR) and saccharopine dehydrogenase (SDH), which are restricted to the mitochondrial matrix. Lysine is presumably transported through the plasma membrane by isoforms(s) of a cationic amino acid transporter (CAT). Although the mechanism(s) of lysine transport through the inner mitochondrial membrane is not known, it is presumptively transported by one or both mitochondrial "ornithine transporters" (ORC-1/ORC-2). Tissue distribution of LKR and the mechanism(s) responsible for alterations in hepatic lysine catabolism in swine are unclear. Also, the roles of the alternative pathways of lysine degradation, the L-amino acid oxidase-dependent (LAAO), in …
The Effect Of Dietary Inclusion Of Conjugated Linoleic Acid In Finishing Hog Feed On Sensory Characteristics And Storage Quality Indicators Of Pork Loin, Kaitlin Hope Maditz
The Effect Of Dietary Inclusion Of Conjugated Linoleic Acid In Finishing Hog Feed On Sensory Characteristics And Storage Quality Indicators Of Pork Loin, Kaitlin Hope Maditz
Graduate Theses, Dissertations, and Problem Reports
Marbling in meat occurs when fat is distributed throughout the skeletal muscle and is visually apparent by light streaks of fat that look like a marble pattern. It is associated with increased quality, tenderness, and likeability. Incorporating dietary conjugated linoleic acid (CLA) into finishing hog feed increases intramuscular fat and decrease backfat in harvested pigs; therefore, the purpose of this study was to determine if inclusion of CLA in pig feed would increase intramuscular marbling and consumer likeability without compromising storage stability. Twenty pigs were housed in ten pens (2 pigs per pen) and fed either 1% Soybean oil or …
