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 ...
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)
was conducted to evaluate the effects of a blend of EO in a commercially available complete feed (MFA Cattle Charge, MFA Inc., Columbia, MO) on performance, health, and feeding behavior of steers during the backgrounding phase. Eighty beef steers (initial BW...
Estimates of correlation between estrus behavior and estradiol concentrations during estrus
(University of Missouri--Columbia, 2020)
Estrus traits have economic value in dairy production systems and can potentially be incorporated into genomic selection. Three studies were performed to further understand selection responses. Study one and two explored ...
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 ...
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 ...
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 ...
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 ...
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...
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 ...
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 ...
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 ...
Evaluating progestin-based protocols to control estrous cycles of beef heifers prior to timed artificial insemination
(University of Missouri--Columbia, 2018)
The recent development of split-time artificial insemination as a breeding strategy improved reproductive outcomes following treatment with the 14d CIDR[copyright]-PG protocol; however, STAI has not been evaluated with ...
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 ...
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 ...
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...
Growth, performance and quality attributes of steers supplemented with high oleic soybean oil
(University of Missouri--Columbia, 2019)
Growing concerns with saturated fatty acids on human health has led to research being done to reduce saturated fatty acid levels in animal tissues. The objective of this study was to evaluate the effect of high oleic soybean ...
Factors affecting neonatal beef calf metabolism and vigor
(University of Missouri--Columbia, 2021)
Two studies were conducted to investigate factors affecting neonatal beef calf metabolism and vigor. In the first study, effects of late gestational nutrient restriction on colostrum yield, neonatal vigor, and blood chemistry ...
