Characterization of Depot Development and the Role of the Novel Adipokine Relaxin in Regulating Lipid Metabolism, Endocrine Function and the Extracellular Matrix in Porcine Adipose Tissue from Lard and Meat-type Pigs

Charlton, Courtney (2019-08-14) ETD File Embargoed

The lard-type, Mangalica pig is a genetic model of excessive adiposity and a breed prized for its excellent pork quality. Therefore, this European heritage breed may serve as a model to improve carcass merit in modern ...

Defining the Porcine Colostral Proteome: Changes in the Array of Proteins from Colostrum to Mature Milk

Silva, Alejandro (2011-08-01)

The importance of colostrum (first milk) for immunological and nutritional support of newborn mammals is well established. Many bioactive peptides are present in milk at higher concentrations than in maternal circulation. ...

Effect of different protein sources on intestinal crypt cell proliferation and density of macrophages in neonatal piglets

Calderon Jimenez, Allan J (2021-11-22) ETD File Embargoed

Pre-weaning mortality is one of the major concerns for the swine industry since it can negatively affect production efficiency. Since the piglet immune system is not fully developed at birth, they are more likely to suffer ...

Effects of Assay Methodology and Standardization for Endogenous Losses of Energy on Determination and Additivity of Metabolizable and Digestible Dietary Energy for Broilers

Philpot, Stephanie (2022-11-16) ETD File Embargoed

Efficient broiler production requires providing birds with diets with appropriate energy density. A lack of additivity of dietary energy could lead to under- or over-supplying energy to broilers. Additivity may be affected ...

The Effects of Days on Feed and Ractopamine HCL Administration on Growth and Carcass Traits of Yearling Heifers

Hittle, Mindy (2011-08-04)

Heifers comprise 30% of the total beef animals slaughtered in the United States yearly. However, heifers are less efficient and have lighter HCW than steers which affects the profitability of heifers. Beta adrenergic ...

The Effects of Lactational Exposure to Soy Isoflavones on Testicular Function in the Rat

Napier, India (2011-08-09)

Testosterone, the male androgen responsible for maintaining the male phenotype, is produced by testicular Leydig cells. Leydig cells express estrogen receptors and are therefore regulated by estrogen. Soybeans predominantly ...

Effects of Ractopamine Hydrochloride on Color Attributes and Meat Quality in Yearling Heifers Across Days on Feed

Hunter, Erin (2010-04-07)

Recent research with the use of β-agonists has been inconclusive from a meat quality standpoint. Therefore, the objective of this study is to evaluate the inclusion of RAC across 5 DOF in 72 crossbred yearling heifers and ...

Establishment of a Model to Evaluate the Effects of Antibiotic-Free Programs on Intestinal Development and Local Immune Response in the Small Intestine of Broiler Chickens

Keel, Andrew (2020-07-17)

In the United States, consumption of chicken has doubled in recent years, making it an important protein source for American families. Recently, the broiler industry has begun to shift away from the use of antibiotic growth ...

Exploratory Study of Ectoparasites of Medical & Veterinary Importance in Alabama

Wong, Natalie (2023-08-21) ETD File Embargoed

Ectoparasites play a critical role in affecting the health and economic prosperity of both human and animal populations. This thesis presents a study focusing on two prominent ectoparasites within Auburn, Alabama: horn ...

Investigating the ability of traditional and molecular methods to differentiate between reproductive potentials in Bos taurus heifers

Rutledge, Lauren (2021-07-13)

Within the livestock industry, one of the main problems that a producer faces is infertility. Infertility in cattle can lead to an animal being removed from cow-calf operations earlier in their lifetime. Reproductive ...

Investigating the role of connexin 43 in oocyte developmental competence

Read, Casey (2018-07-09)

In this study we are committed to understanding the role of connexin 43 (CXx43)-based, cumulus cell cellular coupling and its relationship to bovine embryo development. Several studies have provided clear evidence that ...

The Lactocrine Hypothesis and Laser Microdissection: Evaluating Tissue-Specific Effects of Milk-Borne Factors on Gene Expression in the Neonatal Porcine Uterus

Miller, Dori (2014-05-29)

In the pig, development of the uterus begins in utero and is promoted postnatally via communication of milk-borne bioactive factors (MbFs) that advance development of neonatal somatic tissues. The passage of MbFs from ...

The Mangalica Pig is a Novel Biomedical Model for Human Obesity and its Metabolic Complications

Roberts, Morgan (2015-05-29)

The Mangalica pig is a genetic model of excessive adiposity; therefore, this European heritage breed may serve as an applied model to improve pork quality in modern commercial lean breeds and as a biomedical model to ...

Nutritional strategies for mitigating wooden breast and white striping myopathies of the Pectoralis major muscles in broiler chickens

Meloche, Kathryn (2017-04-17)

Throughout the last decade, broiler producers have increasingly noted the presence of wooden breast (WB) and white striping (WS) in the Pectoralis major muscles (breast fillet) of broilers. Non-genetic factors, such as ...

Pannexin 1 Expression in Bovine Cumulus-Oocyte Complexes and Function During in vitro Maturation

Dye, Zachary (2019-07-03)

In this study we investigate the presence of pannexin 1 (PANX1) protein channels in bovine cumulus-oocyte complexes (COCs). Pannexin channels are a recently discovered family of proteins which have been characterized in ...

Preconditioning for long-duration transportation stress on beef cattle with rumen-protected methionine supplementation: a nutrigenetics study

Alfaro, Gastón (2019-11-22)

Different participants generally located distantly among them compose the U.S. beef production chain; therefore, shipping is required for cattle at least once in their lifespan. The aim of this study was to determine the ...

Recommended duration for evaluating feed intake and validating the residual feed intake model in Brangus heifers

Mahler, Lauren (2016-12-09)

In order to determine optimal measurement days, variables best describing variation for dry matter intake (DMI) and effect of residual feed intake (RFI) classification on reproductive and performance traits, RFI was predicted ...
