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 ...
Improving viability of immunodeficient RAG2-/- pigs by non-specific porcine antibody administration
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Immunodeficient swine models such as the RAG2-/- model, are valuable to the field of regenerative medicine; however, their utility would greatly benefit ...
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 ...
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, ...
Envelopment of a fibroblast growth factor 21 assay
(University of Missouri--Columbia, 2017)
Obesity and diabetes play a major role in many diseases prevalent in our current society. Fibroblast Growth Factor 21 (FGF21) is a recently discovered hormone that has potential for therapeutic treatment of obesity and ...
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 ...
Genomic localization of a feline congenital hydrocephalus
(University of Missouri--Columbia, 2016)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] An inherited congenital hydrocephalus (CH) was identified after an Oriental shorthair male with "cobby" ears was used in the development of Toygers, ...
Modification of porcine rhodopsin by CRISPR/Cas9 : towards a model for Retinitis Pigmentosa
(University of Missouri--Columbia, 2016)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Retinitis Pigmentosa (RP) is a disease characterized by progressive vision loss, which affects approximately 1 in 4,000 people in the United States. ...
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 ...
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 ...
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 ...
Effect of pre-ovulatory follicle size on oocyte transcript abundance in beef cows
(University of Missouri--Columbia, 2016)
Inadequate oocyte competence is a potential explanation for reduced pregnancy rates and(or) increased late embryonic mortality when small dominant follicles are induced to ovulate prematurely with gonadotropin releasing ...
Effects of heat stress on leukocyte function and gene expression in lactating dairy cows
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The effects of heat stress in animal agriculture are expected to become more serious as global temperatures continue to increase. Negative effects on ...
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 ...
Development and evaluation of the 7 and 7 synch protcol for enhanced control of the bovine estrous cycle among postpartum beef cows
(University of Missouri--Columbia, 2019)
Experiment 1 was designed to evaluate the effect of treatments in advance of gonadotropin-releasing hormone (GnRH; 100 [mu]g gonadorelin) administered at the start of estrus synchronization. We hypothesized that administration ...
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 ...
The role of the mammary gland during heat stress
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Disruptive effects of climate change, such as increasing environmental temperature, have direct impacts on economic viability and efficiency of food ...
Novel alkaloid management strategies for improved beef cattle production in the fescue belt
(University of Missouri--Columbia, 2019)
Tall fescue (Schedonorus arundinaceus) is an important forage crop for agriculture in Missouri and much of the eastern United States. Tall fescue is known for hardiness and herbage accumulation, much of which is attributed ...
