Biological characteristics of Katahdin sheep selected for footrot resistance
(University of Missouri--Columbia, 2014)The objectives of this study were to select sheep divergent for a footrot resistant genotype by screening with the DQA2 gene marker and to investigate the host resistant immune response, neutrophil phagocytic efficiency, ... -
Biological role of conceptus derived factors during early pregnancy in ruminants
(University of Missouri--Columbia, 2016)In cycling domestic animals, pregnancy loss during early gestation is a major cause of infertility. The majority of pregnancy loss during this time is due to errors in mitotic division early in development, or occurs later ... -
Biology of uterine glands : impact on reproductive function
(University of Missouri--Columbia, 2018)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Pregnancy loss is the most common complication of human gestation, and roughly one-half of conceptions result in pregnancy loss, most frequently in the ... -

Biomarker assessment for detection of joint pathology in horses and evaluation of the nutritional supplement Steadfast equine as a therapeutic
(University of Missouri--Columbia, 2012)Degenerative joint disease (DJD) is one of the most prevalent musculoskeletal disorders seen in horses, resulting in loss of performance ability, early retirement and significant cost to horse owners. Biomarkers of tissue ... -
Cattle production : the cost in Missouri of producing a steer ready for the feed lot
(University of Missouri--Columbia, 1906)If one desires to know the cost of making a locomotive he would not think of going to anyone other than a locomotive manufacturer. If one wishes to know the cost of constructing a building he goes to a contractor. Desiring ... -
Characterization of a transgenic pig model carrying green fluorescent proteasomes
(University of Missouri--Columbia, 2013)The Ubiquitin Proteasome System (UPS) participates in many biological processes involving substrate-specific proteolysis, and can be linked to various pathologies and genetic diseases. Unfortunately, little is known about ... -
Characterization of apoptosis in the developing bovine fetal ovary: association with germ cell loss
(University of Missouri--Columbia, 2008)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] During early bovine fetal development a 170 fold increase in germ cells occurs from d 50 to 110 followed by a rapid decline of germ cells by d 170. To ... -
Characterization of grape condensed tannins and their effect on Black Rhinoceros (Diceros bicornis) hindgut fermentation
(University of Missouri--Columbia, 2014)African black rhinoceros wild populations have decreased 97 percent since the 1960s, mainly as a result of poaching and the species is classified as Critically Endangered. Captive populations are managed to ensure survival ... -
Characterization of interleukin-1 beta 2, a novel interleukin-1 expressed by the early pig conceptus during establishment of pregnancy
(University of Missouri--Columbia, 2014)It is essential that the early mammalian embryo attaches to the uterus or implants to survive. Most embryonic mortality is associated with complications during this process resulting in a loss of 25-60% of embryos or ... -
Characterization of progesterone receptor (PGR) mRNA and protein isoforms in the endometrium of cyclic and pregnant pigs
(University of Missouri--Columbia, 2010)Disappearance of the progesterone receptor (PGR) from the uterine luminal epithelium (LE) is essential for cyclicity and pregnancy in pigs. In humans, three PGR mRNA isoforms (PGR-A, PGR-B and PGR-C) arise from alternative ... -
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 ... -
Comparative transcriptional profiling of the uterus according to stage of the estrous cycle and pregnancy status in gilts
(University of Missouri--Columbia, 2007)In most mammals, female reproductive tracts undergo extensive tissue remodeling throughout the estrous cycle and during pregnancy that arise in response to an array of endocrine, paracrine, and autocrine signals. These ... -
Comparison of CIDR-based protocols to synchronize estrus in beef heifers
(University of Missouri--Columbia, 2007)Estrus synchronization and artificial insemination (AI) are reproductive management techniques that allow beef producers to enhance the reproductive efficiency and genetic composition of their cow herd. However, U.S. beef ... -
Comparison of controlled internal drug release (CIDR)-based protocols to synchronize estrus and facilitate artificial insemination (AI) in postpartum beef cows
(University of Missouri--Columbia, 2008)Artificial insemination (AI) and estrous synchronization are reproductive technologies that enable beef producers to efficiently improve herd genetics. The recent development of protocols designed to synchronize estrus and ... -
Comparison of long-term CIDR-based protocols to synchronize estrus and ovulation prior to fixed-time artificial insemination in postpartum beef cows
(University of Missouri--Columbia, 2012)This experiment compared two long-term CIDR-based protocols to synchronize estrus and ovulation prior to fixed-time AI (FTAI) in postpartum beef cows. Cows assigned to the 14-19 d CIDR-PG protocol (n = 196) received CIDR ... -
Comparison of long-term CIDR-based protocols to synchronize estrus in postpartum beef cows
(University of Missouri--Columbia, 2011)Estrus synchronization and artificial insemination are two of the most important management practices available to producers to increase reproductive performance in a beef cow-calf operation. Unfortunately, a small number ... -
Comparison of long-term progestin-based protocols to synchronize estrus in beef heifers
(University of Missouri--Columbia, 2009)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Experiment 1 evaluated two long-term progestin-based and controlled internal drug release estrus synchronization protocols to determine their potential ... -
Comparison of rumen microbe taxa among wild and domestic ruminants
(University of Missouri--Columbia, 2015)Microbes that inhabit the rumen provide a diverse set of enzymes that degrade ingested plant material. Without microbes, ruminants could not survive. Our research has focused on identifying microbial taxa associated with ... -
Comparison of thermoregulatory mechanisms in heat sensitive and tolerant breeds of Bos taurus cattle
(University of Missouri--Columbia, 2008)Two Bos taurus breeds with known differences in heat tolerance were tested under controlled conditions to evaluate heat tolerance. Romosinuano (RO) is a tropically adapted breed. Nine Angus (304 [plus or minus] 7 Kg BW; ...
