Developmental exposure to bisphenol a (BPA) and ethinyl estradiol (EE) and effects on F1 parental care and F2 pup parameters in California mice (Peromyscus californicus)
(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 disease (DOHaD). Endocrine...
Interaction of metsulfuron and nitrogen fertilizer in Tall Fescue forage systems
(University of Missouri--Columbia, 2022)
Tall Fescue (Schedonorus arundinaceus) is an introduced cool-season bunch grass that is a vital component of forage systems that support beef cattle production in Missouri and much of the eastern United States. This cool-season grass is known...
Taxonomic and metagenomic approaches to diet, health, and breeds of ruminants
(University of Missouri--Columbia, 2020)
Ruminant mammals maintain a symbiotic relationship with their gut microbiome, the organisms of which break complex plant matter into metabolites that are absorbed by the host animal for its nutrition. Building on prior ...
Evaluating pig performance, carcass merit and processed pork quality when chestnuts and acorns are fed to Duroc-influenced pig genetics during late finishing
(University of Missouri--Columbia, 2019)
The objective of this study was to determine effects of feeding chestnuts and acorns on growth performance, carcass quality and further processed products of Duroc/Duroc crossbred finishing barrows. Barrows (n = 30) were ...
Evaluation and development of early pregnancy diagnosis in dairy cattle
(University of Missouri--Columbia, 2018)
Early chemical pregnancy tests for use in dairy cattle are necessary to aid in reducing the costs associated with days the animal is not pregnant. Identifying non-pregnant dairy cattle sooner would allow for efficient ...
Factors affecting neonatal and peripartum maternal metabolism and behavior in beef cattle and horses
(University of Missouri--Columbia, 2018)
Three studies were conducted to investigate perinatal changes in metabolism and behavior of beef cattle and horses. In the first study, effects of parity on perinatal nutrient availability assessed through calf size and ...
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, ...
Conceptus interferon gamma is essential for pregnancy maintenance in the pig
(University of Missouri--Columbia, 2021)
Establishment and maintenance of pregnancy in the pig is a complex process that relies on adequate communication between the conceptus and maternal uterine endometrium. During the peri-implantation period, the conceptuses ...
New perspective on the role of conceptus estrogens in conceptus development, maternal recognition, and the establishment of pregnancy in pigs.
(University of Missouri--Columbia, 2018)
The proposed signal for maternal recognition of pregnancy in pigs is estrogen, produced by the elongating conceptus. To understand the role of estrogen in porcine conceptus elongation and pregnancy establishment, a loss ...
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 ...
Effects of heat stress and fescue toxicosis on the immune system and other physiological parameters
(University of Missouri--Columbia, 2010)
Tall fescue is widely used as pasture grass in the United States, and is the most important cool season grass for grazing animals. Certain fungi also grow on these grasses which produce toxins, resulting in reduced feed ...
Uterine regulation of preimplantation embryo development in fertility-classified heifers
(University of Missouri--Columbia, 2018)
Infertility and subfertility represent pervasive problems in domestic animals and humans, and embryonic mortality is a major factor influencing reproductive efficiency. In cattle, the majority of embryonic loss occurs ...
Characterization of the genetic landscape of feline oral squamous cell carcinoma
(University of Missouri--Columbia, 2022)
Over 94 million domestic cats are susceptible to cancers and other common and rare diseases. While cancer treatment in cats increasingly mirrors that available in humans, treatment failures are more frequent. There are no ...
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 ...
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 ...
Regulation of fetal brain development in short versus long lived mice
(University of Missouri--Columbia, 2022)
result, most Cav-1- null mice die within a year. Gene expression in bulk brain tissue as well as single cells were analyzed in the Cav-1-null fetal brain compared to the wildtype (WT). The results of this study showed that lack of Cav-1 leads to extensive...
Investigating the role of a lncRNA (4833427F10Rik) in mouse placental development and function
(University of Missouri--Columbia, 2022)
Long non-coding RNAs (lncRNAs) have traditionally been viewed as transcriptional noise. However, experimental evidence of their cell-type-specific expression, presence of functional genetic elements, along with their role ...
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 treatment of infertility...
Glutamine metabolism and interactions with mechanistic target of rapamycin complex 1 in porcine preimplantation embryos
(University of Missouri--Columbia, 2021)
The ability to culture embryos has created opportunities for animal agriculture, including the refined selection of superior genetics, and for the medical field, allowing couples experiencing infertility to have biological ...
Implications of ovarian and uterine maturity evaluated in replacement heifer candidates
(University of Missouri--Columbia, 2021)
Profitability across the reproductive lifetime of a cow depends on reproductive success in the first breeding season and requires heifers to attain puberty prior to this time. Pre-breeding evaluations may be used to determine ...
