Effects of dietary melamine and cyanuric acid in young Pekin ducks and weanling pigs
(University of Missouri--Columbia, 2012)
In 2007, melamine (MEL) and cyanuric acid (CYA) were added to feed ingredients in an attempt to artificially increase their crude protein and thus their momentary value. However, once ingested MEL and CYA can form insoluble ...
Tissue inhibitor of metalloproteinase-1 contributes to ovulatory dysfunction in a rat model of endometriosis
(University of Missouri--Columbia, 2011)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Endometriosis causes ovarian dysfunction, but the mechanisms are unknown. These experiments utilize a rat model of surgically-induced endometriosis ...
Size-dependent acquisition of global DNA methylation in oocytes is altered by hormonal stimulation
(University of Missouri--Columbia, 2011)
Administration of exogenous gonadotropins (superovulation) is used to increase the number of mature oocytes to circumvent the inefficiencies of the subsequent assisted reproductive technologies procedures. Some evidence ...
Function and gene expression of circulating neutrophils in dairy cows : impact of micronutrient supplementation
(University of Missouri--Columbia, 2012)
Three experiments were conducted to investigate the mechanisms of neutrophil dysfunction during the periparturient period and test potential nutritional strategies to prevent the immune-alteration typical of this time. The ...
Phenotypic and genetic effects of disposition on beef tenderness and quality attributes
(University of Missouri--Columbia, 2011)
Cattle temperament (exit velocity; EV) and steak tenderness (Warner-Bratzler shear force) have been shown to be associated in Bos indicus cattle (Behrends et al., 2009). Both traits potentially provide opportunities for ...
Effect of ovulatory follicle size on steroidogenic capacity, molecular markers of oocyte competence and bovine pregnancy associated with glycoproteins in beef cows
(University of Missouri--Columbia, 2011)
Artificial insemination (AI) and estrus synchronization (ES) are effective tools for the genetic advancement of cattle. Gonadotropin-releasing hormone (GnRH) is used at the beginning of ES protocols to induce ovulation and ...
Evaluation of in vitro and in vivo equine microbial population shifts in response to colic conditions
(University of Missouri--Columbia, 2011)
We designed two continuous culture experiments to test the effects of starch dosage and starvation upon equine fecal microflora. Diets were designed containing fructooligosaccharides and mannanoligosaccharides in order to ...
Establishment of a phenotypical model of adverse outcomes associated with assisted reproductive technologies
(University of Missouri--Columbia, 2011)
Beckwith-Wiedemann syndrome (BWS) is a loss-of-imprinting pediatric overgrowth syndrome. BWS is speculated to occur primarily as the result of the misregulation of imprinted genes associated with two clusters on chromosome ...
Feed additives affect pork quality and shelf-life from pigs fed ethanol co-products and pork subject to three storage methods
(University of Missouri--Columbia, 2011)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Two experiments were performed to determine the effect of corn distiller's dried grains with solubles on meat quality when fed at two different inclusion ...
Comparison of long-term CIDR-based protocols to synchronize estrus in postpartum beef cows
(University of Missouri--Columbia, 2011)
Estrus synchronization and artificial insemination are two of the most important management practices available to producers to increase reproductive performance in a beef cow-calf operation. Unfortunately, a small number ...
Modeling the amino acid requirements of male turkeys from 0 to 21 weeks of age
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] An experiment was conducted to determine the effects of diets formulated using the ideal protein concept and modeled amino acid requirements with diet ...
Genotype by environment interactions for growth and stayability in US red Angus
(University of Missouri--Columbia, 2012)
Genotype by environment interactions (GxE) may reduce accuracy of sire selection. The objectives of this study were to evaluate the presence of GxE by comparing reaction norms of bulls for birth weight, weaning weight, ...
Biomarker assessment for detection of joint pathology in horses and evaluation of the nutritional supplement Steadfast equine as a therapeutic
(University of Missouri--Columbia, 2012)
Degenerative joint disease (DJD) is one of the most prevalent musculoskeletal disorders seen in horses, resulting in loss of performance ability, early retirement and significant cost to horse owners. Biomarkers of tissue ...
Utilizing laboratory and field studies to determine physiological responses of cattle to multiple environmental stressors
(University of Missouri--Columbia, 2012)
Heat stress and fescue toxicosis, resulting from intake of endophyte-infected fescue, have significant impacts on physiological processes in cattle. To study this impact, we used numerous physiological measures of thermal ...
Mitochondrial complex I protein is related to residual feed intake in beef cattle
(University of Missouri--Columbia, 2011)
Residual feed intake (RFI) is a calculated using DMI as dependent variable and metabolic body weight (BW 0.75) and ADG as independent variable. Mitochondria complex I (mitochondrial NADH:ubiquinone oxidoreductase) is one ...
NIR fluorescent sensors for blood pH and fructose
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Blood serum parameters are tightly associated with human beings' physiological activities, therefore the real-time monitoring of blood serum parameters ...
Generation and characteriazation of porcine induced trophoblast
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Trophoblast stem cells are progenitors of all trophoblast lineages that compose fetal placental portion. Trophoblast stem cells provide an unlimited ...
Shelf stability and quailty of fresh ground pork and pork sausage from pigs fed ethanol co-products
