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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
Applications of ancestry estimation in cattle population genetics
(University of Missouri--Columbia, 2019)
Accounting for ancestry and cryptic population structure is important in population genetic data analysis. The estimation of ancestry can help elucidate the effects of admixture or stratification on allele and genotype ...
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 ...
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 ...
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 ...
