MILK AND BLOOD CONCENTRATIONS OF LIPOPOLYSACCHARIDE-BINDING PROTEIN IN COWS WITH NATURALLY-OCCURRING SUBCLINICAL AND CLINICAL MASTITIS
(2008-08-22)
The objective of this thesis was to evaluate the blood and milk concentrations of lipopolysaccharide-binding protein (LBP) from cows with naturally-occurring mastitis as biomarkers of this disease. Milk and blood samples ...
Separating the Effects of Group Size, Density, and Enclosure Size on Movement and Use of Space in Domestic Fowl (Gallus gallus domesticus)
(2008-04-24)
This project was designed to separate the confounded effects of group size, density, and enclosure size, and to examine the role of enclosure design and its related parameters in shaping movement patterns and use of space ...
Inhibition of PRRSV Replication by Combination of Antisense Morpholino Oligomers
(2008-08-22)
Porcine reproductive and respiratory syndrome (PRRS) has caused heavily economic losses in the swine industry worldwide and current strategies to control PRRS are inadequate. Previous studies have shown that antisense ...
The effect of sperm mobility phenotype on fertility persistence in layer and broiler hens
(2008)
Domestic fowl (Gallus gallus domesticus) were studied to identify accurate predictors of potential fertility in two lines of broiler breeder males along with fertility persistency in layer and broiler hens. Sixty-four ...
Towards the derivation of bovine embryonic stem cells
(2008-01-28)
The ability of embryonic stem cells (ESCs) to self-renew and differentiate into a wide range of cell types has encouraged researchers to attempt to isolate ESCs from embryos of domestic species for the past two decades. ...
Regulation of milk fat synthesis by dietary fatty acids
(2008-08-04)
The objectives of this thesis research were to determine the molecular mechanisms by which dietary fatty acids (FA) regulate lipogenic gene expression and milk fat synthesis. Principal component and multivariate analyses ...
The potential role of butyrophilin and xanthine oxidoreductase in controlling the amount and size of milk-fat droplets
(2008-08-05)
The secretion of fat droplets from mammary epithelial cells requires the expression of two major proteins, butyrophilin1A1 (BTN) and xanthine oxidoreductase (XOR). Ablation of the BTN or XOR gene in mice results in the ...
Post-bottleneck inbreeding accumulation reduces fitness in laboratory populations of <italic>Tribolium castaneum</italic> under environmental stress
(2008)
Populations are often driven to extinction due to low genetic diversity. One major cause for loss of genetic diversity in a population is a demographic bottleneck. A demographic bottleneck was imposed on twenty-one populations ...
Identification and characterization of a heme responsive element in the hrg-1 promoter
(2008)
Despite its biological significance, little is known about how animals sense and respond to heme to maintain homeostasis. C. elegans is a heme auxotroph, which makes it an excellent model to identify and dissect heme ...
Regulation of factors contributing to virulence in Escherichia coli
(2008-04-25)
Extraintestinal pathogenic strains of Escherichia coli cause a wide range of diseases including colibacillosis in chickens and urinary tract infections in humans. Persistent infections in E. coli and other gram-negative ...
