Negative biomarkers of sperm quality and male fertility
(University of Missouri--Columbia, 2011)
labeling with an anti-PAWP antibody. Measurements yielded statistically significant correlations between PAWP intensities and several fertility parameters used by the AI industry. Based on these two studies, we conclude that biomarkers such as SCSA and PAWP...
An investigative study on neutron emissions from titanium- deuterium system under thermal shock
(University of Missouri--Columbia, 2017)
neutron burst, suggesting that neutron emission is a statistical process occurring at low probability. The neutron burst was observed from partially deuterated titanium samples. The level of neutrons detected is consistent with what has been reported...
Evaluation of heat-processed sorghum, high-oleic and low-trypsin inhibitor soybean cultivars as alternatives for corn and conventional soybeans for broilers
(University of Missouri--Columbia, 2017)
) was included in all diets as a digesta flow marker. Excreta and ileal samples were collected on d 21. Statistical analyses were performed as a completely randomized design using PROC GLM of SAS with significance level set at P less than or equal to 0.05. In Exp...
Quantitative trait loci mapping and candidate gene analysis for growth and carcass traits on two bovine chromosomes
(University of Missouri--Columbia, 2006)
The first objective of this study was to identify genomic regions on BTA4 and BTA14 which harbor QTL affecting weight and carcass traits in a commercial Angus population. The mapping population consisted of 1,510 purebred ...
Heritable, differential gene expression in pre-implantation embryos from rats with endometriosis and their daughters
(University of Missouri--Columbia, 2010)
reveal a treatment to prevent these anomalies during embryo development.--From public.pdf...
Phenotypic and genetic effects of disposition on beef tenderness and quality attributes
(University of Missouri--Columbia, 2011)
Information Criteria (Gilmour et al., 2006) values were utilized to evaluate the fit of alternative statistical models to the data. A near zero genetic correlation was estimated between APSF and EV. Moderate heritability estimates were found for both APSF...
Genotype by environment interaction estimated by using reaction norms in cattle
(University of Missouri--Columbia, 2008)
of progeny within each herd environment was defined as the environmental mean. Four statistical models were analyzed using herd environment (categorical (CM) and genotype by environment (GEM)) or environmental mean (continuous environment (CEM) and random...
Prediction of optimal rumen degradable protein levels in no-roughage, corn-based feedlot diets
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The need to balance no-roughage, corn-based feedlot diets for rumen degradable protein inclusion is essential in the feedlot setting. Five crossbred ...
Effect of high peroxide value fats on performance of broilers in normal and immune challenged states
(University of Missouri--Columbia, 2009)
A series of trials were conducted in order to determine the effects of high peroxide value fats on performance of broilers in normal and immune challenged states from 0-49 days of age. In the first experiment, birds were ...
Evaluation of the efficacy of high levels of microbial phytase in broilers
(University of Missouri--Columbia, 2006)
Three experiments were conducted to evaluate the efficacy of high levels of microbial phytase in broiler diets. In experiment one (EXP 1), phytase was included in the diets at 0, 250, 500, 10,000, and 20,000 PU/kg diet. ...
Transcriptional profiling by deep sequencing indentifies [sic] differences in mRNA transcript abundance in in vivo derived vs. in vitro cultured porcine blastocyst stage embryos
(University of Missouri--Columbia, 2010)
In vitro embryo culture systems promote development at rates lower than in vivo. The goal of this project was to discover transcripts that may be responsible for a decrease of embryo competency in blastocyst stage embryos ...
Influence of seasonal environment, top and bottom deck transport, transport duration, and time in lairage on overall pork quality and blood serum cortisol concentrations of market hogs
(University of Missouri--Columbia, 2007)
Objectives of this study were to determine effects of seasonal environment, top and bottom deck transport, transport duration, and time in lairage on overall pork quality and blood serum concentrations of the stress hormone ...
The effects of supplemental anionic salts & yeast culture on the production of dairy cattle during the periparturient period
(University of Missouri--Columbia, 2006)
The objective of this thesis was to determine nutritional strategies with the strategic use of feed additives during the periparturient period to reduce the negative energy balance as the dairy cow transitions from late ...
The relationship between mitochondria and residual feed intake in feedlot cattle
(University of Missouri--Columbia, 2006)
Residual feed intake (RFI) is a measure of feed efficiency that is not related to an animal's growth rate or body size. Little is known about the factors that affect RFI because, until recently, the measurement of RFI in ...
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 ...
Approaches for alleviating toxic effects of aflatoxin in lactating dairy cows and weanling pigs
(University of Missouri--Columbia, 2010)
Aflatoxin (AF) is a mycotoxin found in feed ingredients used in livestock diets including dairy cattle and pigs. Aflatoxin causes reduced performance, liver damage, increased prevalence of infectious disease, and secretion ...
Effects of aflatoxin on hepatic gene expression in a poultry model
(University of Missouri--Columbia, 2008)
To determine the effects of dietary aflatoxin on hepatic gene expression in chicks, seventy five day old-male broiler chicks were assigned to three dietary treatments (0, 1 and 2 mg/kg aflatoxin/kg of feed) from hatch to ...
