(University of Missouri--Columbia, 2017)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Environmental exposure during the perinatal period can promote health and disease in offspring, otherwise coined developmental origins of health and ...
Genetics in practice : applications of quantitative genetics to environment and educational pursuits
(University of Missouri--Columbia, 2018)
"The ability to elucidate quantitative trait architecture and introduce potentially beneficial traits makes introgression a useful tool. Unfortunately, due to the nature of inheritance there are certainly limitations to ...
Self-selection of animal by-product by poultry through utilization of choice feeding
(University of Missouri--Columbia, 2020)
"The emergence of animal welfare provisions by humane societies has limited management practices. One of these provisions is the animal's freedom to express normal behavior. Animal by-product feeding to livestock and poultry ...
Zinc ion fluxes on the pathway to mammalian sperm fertilization competency
(University of Missouri--Columbia, 2019)
For decades, the role of the divalent ion calcium was the focus of understanding mechanisms leading to sperm fertilization competency and management of semen storage. Little focus has been placed on other divalent ions, ...
Effects of essential oils on the performance, health, and feeding behavior of growing cattle
(University of Missouri--Columbia, 2021)
Concerns and changes in policy related to use of antimicrobials in livestock has led to increased interest in using alternative feed additives such as essential oils (EO). Essential oils are plant secondary metabolites ...
Determination of allelic expression of H19 in pre- and peri-implantation mouse embryos
(University of Missouri--Columbia, 2013)
H19 is a maternally-expressed imprinted non-coding RNA with tumor suppressor activity. H19 is located in an imprinted cluster which contains the paternally-expressed fetal growth factor Igf2. Monoallelic expression of H19 ...
Regulation of fetal brain development in short versus long lived mice
(University of Missouri--Columbia, 2022)
and background of brain development and aging are provided review of literature (Chapter 1). In the first study (Chapter 2), experiments were performed to test early-life origin of brain aging. Mouse epigenetic clock (epiclock) database which represents specific...
Effects of bovine pregnancy-associated glycoproteins on gene transcription in bovine endometrial explants
(University of Missouri--Columbia, 2021)
Pregnancy-associated glycoproteins (PAGs) are a complex gene family, whose members are expressed by trophoblasts of ruminants and related species. In cattle, the PAGs accumulate at the trophoblast-uterine interface and ...
Gene expression profiling of bovine ovarian follicular selection
(University of Missouri--Columbia, 2006)
Lack of, or abnormal, ovarian follicular development is a major factor associated with impaired fertility in mammals. However, development of new treatments is limited by our poor understanding of ovarian follicular ...
Protein source selection in nursery pigs during choice-feeding
(University of Missouri--Columbia, 2020)
The animal processing industry is continually growing to meet the demands of a growing human population. It is estimated that with the increasing human populations, the demand for animal proteins will be increasing more ...
Potential diagnostic methods and nutritional changes to combat bovine respiratory disease in receiving cattle
(University of Missouri--Columbia, 2017)
Bovine respiratory disease (BRD) accounts for up to 70 percent of health disruptions and $500 million in associated medical costs and production losses, thus receiving considerable attention from cattle health personnel ...
Exploration of fecal microbial transfer and the competitive exclusion concept in broilers as a possible alternative to antibiotic growth promoters
(University of Missouri--Columbia, 2021)
Four studies were conducted to explore the effects of early life Fecal Microbiota Transfer (FMT) from healthy feed efficient finished broilers into day-old broiler chicks on growth performance indices, changes and or ...
Applications of ancestry estimation in cattle population genetics
(University of Missouri--Columbia, 2019)
gain and disease susceptibility. Here, we review the methods used for ancestry estimation and the impacts of ancestry prediction in human population genetic analyses and opportunities for use of these techniques in cattle, and more generally...
Molecular regulation of fetal brain development in pigs
(University of Missouri--Columbia, 2021)
Two experiments were conducted to investigate molecular regulation that impacts fetal brain development in pigs. In the first experiment (Chapter 2), gene expression was profiled by RNA sequencing (RNA-seq) to examine the ...
Investigation of methods and factors influencing mouse oocyte quality, in vitro fertilization and embryo development
(University of Missouri--Columbia, 2018)
Mice are one of the most commonly used rodent species as a model for biomedical research to better understand molecular, genetic, and cellular causes of human disease and disorders. The production of good quality oocytes ...
Genomics of heifer pregnancy, days open, and days to conception in Red Angus heifers
(University of Missouri--Columbia, 2022)
Although it is challenging to collect information on reproductive traits, fertility traits are believed to play a significant role in the growth of the beef industry and bring revenue to the producers. It has been challenging ...
Effects of late gestational copper, zinc, and manganese source and inclusion in beef cattle
(University of Missouri--Columbia, 2019)
A study was conducted to determine the effects of source and inclusion of Cu, Zn, and Mn during late gestation on cow and calf mineral status, fetal growth, and offspring immune function and pre-weaning performance. Cows ...
Endocrinology of equine metabolic pathophysiology
(University of Missouri--Columbia, 2006)
Obesity in horses is associated with a number of maladies including insulin resistance and laminitis; therefore studies investigating the metabolic physiology of equine were done. In our first study, we characterized the ...
