Structural variation at the KIT locus is responsible for the piebald phenotype in Hereford and Simmental cattle
(University of Missouri--Columbia, 2014)
The Spotted locus is responsible for white spotting (piebald) coat color phenotypes in cattle. Since the Hereford breed is fixed for this phenotype, we postulate that a selective sweep occurred during breed formation 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 ...
Extracellular vesicles : novel mediators of conceptus-maternal interactions in sheep
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Infertility and pregnancy loss are common problems affecting reproductive efficiency, health and development in livestock. Pregnancy loss occurs most ...
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 ...
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 ...
Ruminal degradation of protein and carbohydrate in the domestic and wild ruminant
(University of Missouri--Columbia, 2010)
To optimize growth and health ruminant animals in a confined setting, diets need to be formulated to provide balanced levels of rumen degradable energy and nitrogen (RDN) to maximize microbial growth while also providing ...
Transgenerational effects of in utero heat stress on reproduction in pigs
(University of Missouri--Columbia, 2017)
Seasonal infertility caused by high ambient temperatures and humidity during the summer months can have negative effects on the reproduction of female swine. These conditions may cause heat stress leading to large economic ...
Paternal developmental exposure to endometriosis causes negative transgenerational impacts on male fertility
(University of Missouri--Columbia, 2018)
Endometriosis is a gynecological disease causing pain and infertility in about 15% of women worldwide. Little is known regarding male fertility following prenatal exposure to endometriosis. Our hypothesis is that developmental ...
Role of preovulatory estradiol in uterine and luteal function
(University of Missouri--Columbia, 2018)
In beef heifers, expression of estrus at fixed-time artificial insemination (FTAI) was associated with increased preovulatory circulating concentrations of estradiol (E2) and increased pregnancy rates compared to heifers ...
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 ...
Regulation of early trophoblast differentiation and development
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Placenta is a transient organ which functions in multiple ways to support the growth and survival of the developing fetus. Placenta plays a critical ...
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 ...
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, ...
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 ...
