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 ...
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. ...
Structural variation at the KIT locus is responsible for the piebald phenotype in Hereford and Simmental cattle
(University of Missouri--Columbia, 2014)
The Spotted locus is responsible for white spotting (piebald) coat color phenotypes in cattle. Since the Hereford breed is fixed for this phenotype, we postulate that a selective sweep occurred during breed formation to ...
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 ...
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 ...
Beef chuck muscle isolation has no effect on premium ground beef programs
(University of Missouri--Columbia, 2014)
This experiment evaluated whether isolating certain muscles from the chuck for retail sale and excluding them from the ground beef mix changes the number of days that ground chuck is acceptable to consumers. Chucks were ...
Applying effective energy concept for intake prediction and balancing ruminal nitrogen and post-ruminal amino acid requirements for beef cattle
(University of Missouri--Columbia, 2013)
Proper animal nutrition involves balancing nutrient supply to nutrient requirement. Accurate intake prediction is fundamental to diet formulation and appears simple but has historically been challenging to accomplish. ...
Characterization of a transgenic pig model carrying green fluorescent proteasomes
(University of Missouri--Columbia, 2013)
The Ubiquitin Proteasome System (UPS) participates in many biological processes involving substrate-specific proteolysis, and can be linked to various pathologies and genetic diseases. Unfortunately, little is known about ...
Large offspring syndrome, a bovine model for the human loss-of-imprinting overgrowth syndrome Beckwith-Wiedemann
(University of Missouri--Columbia, 2013)
Beckwith-Wiedemann syndrome (BWS) is a human loss-of-imprinting syndrome primarily characterized by macrosomia, macroglossia, and abdominal wall defects. BWS has been associated with misregulation of two clusters of imprinted ...
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 ...
Effects of supplementation of dietary antioxidants and chelated trace minerals in periparturient dairy cows and subsequent response to intramammary bacterial challenge
(University of Missouri--Columbia, 2014)
Two experiments were conducted to investigate the effects of supplementation of synthetic dietary antioxidants and different sources of a blend of trace minerals on two distinct situations of immune dysfunction in dairy ...
The effects of reduced protein diets using the Missouri ideal turkey protein on male turkeys from 0 to 21 weeks of age
(University of Missouri--Columbia, 2013)
Protein is one of the major cost components in turkey diets. When diets are formulated on an ideal protein basis, the levels of crude protein decrease with the use of amino acids (AA); performance is maintained and feed ...
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 ...
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 ...
Synchronization and ovarian development in dairy cows and heifers
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Reproductive management is an important factor for improving reproductive efficiency in the dairy industry. Reproductive efficiency affects the ...
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 ...
The effects of leptin on placental development and function, and offspring behavior in mice
(University of Missouri--Columbia, 2014)
The nutritional and energy status of individuals is communicated throughout the body by means of leptin. This hormone also plays a role in implantation and placental development and function, as well as programming behavior ...
Urocortin as a measure of stress in livestock
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Stress is a fact of life for every living thing. In livestock species, stress can affect an animal's performance, thus leading to decreased profit for ...
