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 ...
Dietary fat source alters pork fat quality
(University of Missouri--Columbia, 2010)
During the last decade, several changes have taken place in the swine industry. There has been an increase in the use of distillers dried grains with solubles (DDGS) which, depending on the level included in the diet, may ...
Effects of heat stress and fescue toxicosis on the immune system and other physiological parameters
(University of Missouri--Columbia, 2010)
Tall fescue is widely used as pasture grass in the United States, and is the most important cool season grass for grazing animals. Certain fungi also grow on these grasses which produce toxins, resulting in reduced feed ...
Development of laboratory methods to detect meat tenderness
(University of Missouri--Columbia, 2013)
Tenderness has been identified as one of the most important attributes for consumers concerning their meat quality desire, so there is a clear need to accurately determine and grade meat accordingly to tenderness. A ...
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 ...
Stem cells and DNA methylation reprogramming in pigs
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] In mammals, the majority of cells in the body contain the same genome as other cells. The concept of nuclear totipotency has been well demonstrated by ...
Overcoming endometriosis-associated preimplantation embryo developmental anomalies by culture
(University of Missouri--Columbia, 2013)
Endometriosis, characterized by the localization and establishment of ectopic endometrial tissue, afflicts 10 to 15% of reproductive-aged women worldwide. Due to the anomalous substances secreted from these endometriotic ...
Effect of endophyte-infected tall fescue on hepatic gene expression in cattle
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Fescue toxicosis may result from the intake of ergot alkaloids found in endophyteinfected (E+) tall fescue. The liver if the major organ involved in ...
The inhibition of cysteine peptidases improves in vitro maturation of porcine cumulus-oocyte-complexes
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The cell permeable cysteine peptidase inhibitor, E-64, has shown utility as a potent and irreversible inhibitor for many cysteine proteases. Consequently, ...
Analysis of Gbx genes during neural development
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The understanding of how transcription factors regulate neural patterning in the anterior hindbrain, and how the assembly of specific neuronal circuits ...
Effect of commercial feed additives on production variables and metabolic markers of the periparturient dairy cow
(University of Missouri--Columbia, 2013)
Three experiments were conducted to investigate the effects of commercially available feed additives on production variables and metabolic markers when supplemented during the periparturient period. The hypothesis was that ...
Abundance of TRIM28, SETDB1, and TP53 mRNA is dynamically regulated during porcine early embryogenesis and is abnormal in preimplantation embryos produced by in vitro fertilization in comparison to in vivo derived and nuclear transfer derived embryos
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] In vitro embryo production is important for research in animal reproduction, embryo transfer, transgenics, and cloning. However, in vitro-derived embryos ...
Effects of a commercial feed additive on production losses during acute heat stress conditions in mid-lactation Holstein dairy cows
(University of Missouri--Columbia, 2013)
Heat stress occurs when the environmental temperature exceeds the thermoneutral zone (or comfort zone) of the dairy cow, necessitating the employment of energetically costly cooling mechanisms such as sweating and panting. ...
Essential oil effects on rumen fermentation, animal performance, and meat quality of beef steers
(University of Missouri--Columbia, 2013)
Efficiency in ruminants has historically been improved by using antibiotics and ionophores to alter rumen fermentation. Nutritionists, however, have begun searching for alternative rumen modifiers due to the negative ...
Improving fiber by-product utilization in high concentrate diets
(University of Missouri--Columbia, 2013)
The effects of starch and fiber combinations in feedlot diets were examined to determine maximum whole shell corn (WSC) inclusion rate in high fiber diets and determine the effects of fibrolytic enzyme addition to WSC diets ...
