11 [beta]-hydroxysteroid dehydrogenase activity in feline, equine, and ossabaw swine adipose tissue
(University of Missouri--Columbia, 2007)Enzymatic 11 [beta] HSD1 amplification of glucocorticoid concentrations in adipose tissue has been associated with obesity, diabetes, hypertension, dyslipidemia, and cardiovascular disease in humans and mice. Unfortunately, ... -
Ablation of conceptus PTGS2 provides a new understanding of early pregnancy events in the pig
(University of Missouri--Columbia, 2019)Pig conceptuses produce and secrete estrogens (E[2]), interleukin 1 beta 2 (IL1B2), and prostaglandins (PGs) during the period of rapid trophoblast elongation and establishment of pregnancy. Previous studies established ... -
Abundance of TRIM28, SETDB1, and TP53 mRNA is dynamically regulated during porcine early embryogenesis and is abnormal in preimplantation embryos produced by in vitro fertilization in comparison to in vivo derived and nuclear transfer derived embryos
(University of Missouri--Columbia, 2013)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] In vitro embryo production is important for research in animal reproduction, embryo transfer, transgenics, and cloning. However, in vitro-derived embryos ... -
Age as a factor in animal breeding
(University of Missouri--Columbia, 1911)Many breeders believe in the evil effect of early reproduction. It is said that early marriage has led to the degeneracy of many nations. The domestic animals are national assets and their preservation, like the conservatives ... -
Age as a factor in animal breeding
(University of Missouri--Columbia, 1918)The experiment furnishing the basis for this discussion was begun in 1909 by Director F.B. Mumford and has since been continued under his general direction. Swine were used in the experiment since they probably lend ... -
Alleviation of heat stress with Tasco in dairy cows
(University of Missouri--Columbia, 2010)The present study determined the impact of Tasco, Ascophyllum nodosum, on heat stress in dairy cows. Thirty-two Holstein cows were utilized in a randomized complete block design, during 63 days in summer 2008. Feed intake, ... -
Altered microrna expression profiles in bovine fetuses with an assisted reproduction-induced congenital overgrowth syndrome
(University of Missouri--Columbia, 2018)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Assisted reproductive technologies (ART) refer to a series of fertility treatments used to conceive offspring. ART is used worldwide in humans for ... -
Altering the timing of fixed-time artificial insemination and the interval from progestin withdrawal to prostaglandin F2a administration in estrus synchronization protocols for beef heifers
(University of Missouri--Columbia, 2022)An experiment (Chapter 2) was designed to evaluate later timepoints for fixedtime artificial insemination (FTAI) of beef heifers, with the hypothesis that use of a later timepoint would allow a greater proportion of heifers ... -
An analysis of aspartic peptidases expressed by trophoblasts and placenta of even-toed ungulates
(University of Missouri--Columbia, 2008)The Pregnancy Associated Glycoproteins (PAGs) represent a multigene family of trophoblast expressed proteins, found exclusively in the placenta of even-toed mammals such as ruminants (cattle, sheep), pig, etc. In ruminants, ... -
Analysis of Gbx genes during neural development
(University of Missouri--Columbia, 2013)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The understanding of how transcription factors regulate neural patterning in the anterior hindbrain, and how the assembly of specific neuronal circuits ... -
Analysis of transcript abundance of uterine genes after application of bovine pregnancy associated glycoproteins to endometrial explants
(University of Missouri--Columbia, 2015)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Pregnancy-associated glycoproteins (PAGs) belong to the aspartic protease family and are expressed exclusively by trophoblasts of even-toed ungulates. ... -
Applications of ancestry estimation in cattle population genetics
(University of Missouri--Columbia, 2019)Accounting for ancestry and cryptic population structure is important in population genetic data analysis. The estimation of ancestry can help elucidate the effects of admixture or stratification on allele and genotype ... -
Applying effective energy concept for intake prediction and balancing ruminal nitrogen and post-ruminal amino acid requirements for beef cattle
(University of Missouri--Columbia, 2013)Proper animal nutrition involves balancing nutrient supply to nutrient requirement. Accurate intake prediction is fundamental to diet formulation and appears simple but has historically been challenging to accomplish. ... -
Approaches for alleviating toxic effects of aflatoxin in lactating dairy cows and weanling pigs
(University of Missouri--Columbia, 2010)Aflatoxin (AF) is a mycotoxin found in feed ingredients used in livestock diets including dairy cattle and pigs. Aflatoxin causes reduced performance, liver damage, increased prevalence of infectious disease, and secretion ... -
Arachidonate 15-lipoxygenase and ubiquitin as potential fertility markers in boars
(University of Missouri--Columbia, 2004)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] This study was performed to determine whether using high power microscopic analysis and two putative biochemical fertility markers, 15-lipoxygenase ... -
Assessment of growth, performance, and end-product value when high oleic soybean oil is fed to market hogs, broiler chickens and laying hens
(University of Missouri--Columbia, 2021)For the past decade consumers have become more aware of the food they are eating and demand healthier animal products. The use of dietary oils has allowed the livestock industry to manipulate the fatty acid profiles of ... -
Autophagy and ubiquitin-proteasome system during post-fertilization sperm mitophagy
(University of Missouri--Columbia, 2016)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Maternal inheritance of mitochondria and mitochondrial DNA (mtDNA) is a universal principle in developmental biology. Mammalian sperm-borne mitochondria ... -
