Evaluation of exogenous plant based enzymes in a low-cost foodservice beef model
(University of Missouri--Columbia, 2016)
This study was performed to determine the effects of an exogenous enzyme on the tenderness of beef hanging tenders over a 3-day storage period. The objectives were to evaluate the Slice Shear Force, myofibrillar fragmentation ...
Genetic linkage of multiple modifications in the pig
(University of Missouri--Columbia, 2015)
Genetic engineering facilitates heritable modification of target genomes. Modifications can be site-specific or random. Though inefficient, homologous recombination allows for precise genome modification. Random integration ...
An investigative study on neutron emissions from titanium- deuterium system under thermal shock
(University of Missouri--Columbia, 2017)
The purpose of this study is to investigate the titanium-deuterium system under thermal shock, as a potential neutron source. The expected neutron emission is unique, i.e. it is monoenergetic with energy of 2.45 MeV, which ...
A phenomenological study of queer and trans students of color
(University of Missouri--Columbia, 2017)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Queer and trans student experiences are understudied in higher education, quantitatively and qualitatively alike. Despite the number of studies growing ...
Considerations for reproductive management of bos indicus-influenced beef heifers
(University of Missouri--Columbia, 2017)
The Bos indicus species of beef cattle presents a number of unique reproductive challenges, especially with regard to those that influence reproductive efficiency including timely attainment of puberty, response to certain ...
Metabolic programming of a Warburg effect-like phenotype in donor fibroblasts prior to somatic cell nuclear transfer
(University of Missouri--Columbia, 2017)
Gene edited pigs serve as excellent models for biomedicine and agriculture. Currently, the most efficient way to make a reliably-edited transgenic animal is through somatic cell nuclear transfer (SCNT) also known as cloning. ...
Efficacy of various wavelengths of light emitting diode illumination on efficiency and performance parameters of broilers
(University of Missouri--Columbia, 2016)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Lighting is essential for broiler growth, maturation, and reproduction. Globally, broilers are reared under various production systems including outdoor ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
Phosphorus digestibility of corn and soybean meal (SBM) in broilers : in search of a consistent and reliable model to quantify individual ingredient contribution
(University of Missouri--Columbia, 2017)
Two experiments were conducted to determine true digestibility of Phosphorus (P) in feed ingredients commonly in commercial broiler diets. A second objective was to determine if the true digestible P values of corn and ...
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 ...
The impact of fescue toxicosis & T-Snip score on post-weaning beef cattle performance
(University of Missouri--Columbia, 2017)
It is well known that fescue toxicosis has a negative impact on cattle productivity. These studies were conducted to evaluate the effects of fescue toxicosis on post-weaning beef steers, as well as the impact of T-Snip ...
Molecular characterization of a congenital overgrowth syndrome induced by assisted reproduction
(University of Missouri--Columbia, 2017)
Beckwith-Wiedemann syndrome (BWS) is a congenital overgrowth condition with increased likelihood to develop childhood tumors. Children conceived with the use of assisted reproductive technologies (ART) have an increased ...
