Nutritional and Physiological Control of Metabolic Pathways That Alter Milk Protein and Lactose Synthesis by the Mammary Gland
(2006-12-08)
The objectives of this research were to develop a [U-<sup>13</sup>C]glucose tracer approach establishing the pathways and substrates for milk lactose and casein synthesis, and determine the influence of protein ...
THE EFFECTIVENESS OF DUAL ENERGY X-RAY ABSORPTIOMETRY TO NON-INVASIVELY DETERMINE BODY COMPOSITION OF HYBRID STRIPED BASS
(2004-05-12)
The primary objective of this research project was to determine if dual energy x-ray absorptiometry was a valid method for non-invasively determining body composition of hybrid striped bass (Morone chrysops ♀ x. ...
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 ...
Effects of embryonic exposure to androgen-active endocrine disrupting chemicals in Japanese quail
(2005-04-18)
Endocrine disrupting chemicals (EDCs) are compounds that alter the production, secretion, action, and elimination of endogenous hormones. EDCs have been shown to be responsible for disrupting development, reproduction, ...
Regulation of macronutrient metabolism by the gastrointestinal tract of ruminants
(2006-07-28)
We set out to test the hypothesis that the gastrointestinal tract (GIT) of ruminant animals catabolizes amino acids (AAs) preferentially. We sought to determine whether this catabolism represents an obligate requirement, ...
Quantitative Trait Loci and Promoter Analysis of the Bovine Butyrophilin Gene
(2004-01-27)
The butyrophilin gene (BTN1A1) has been described in all mammalian species so far investigated. BTN1A1 is a likely QTL candidate that affects an economically important trait in dairy animals because it is specifically ...
Regulation of Urea Recycling into the Gastrointestinal Tract and Ammonia Metabolism in Ruminants
(2004-12-08)
The primary objective of this study was to determine the extent ruminants control urea recycling to the gastrointestinal tract (GIT), independent of rumen microbial metabolism. Urea kinetics were determined by continuous ...
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 ...
A STUDY OF GLUCOSE METABOLISM AND KETOSIS DEVELOPMENT IN PERIPARTURIENT COWS USING A MECHANISTIC MODEL
(2005-04-11)
Periparturient cows are susceptible to ketosis. An animal trial was conducted to evaluate the effect of a transition diet on production performance and ketone body (KB) accumulation. The transition diet was fed from 14 ...
