A Model to Predict Fluctuations in Rumen pH
(2005-05-11)
Factors affecting pH and the mechanism of rumen pH control are poorly understood. Meta-analysis was conducted to estimate the effect of sodium bicarbonate (NaHCO3) on rumen pH. Addition of NaHCO3 increased strong ion ...
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 ...
FUNCTIONAL STUDIES OF INFECTIOUS PANCREATIC NECROSIS VIRUS PROTEINS AND MECHANISM OF VIRUS-INDUCED APOPTOSIS
(2003-12-04)
Infectious pancreatic necrosis virus (IPNV) encodes a 12 or 15-kDa nonstructural protein, known as VP5. To study the function of VP5, we generated three recombinant viruses rNVI15, rNVI15-15K, and rNVI15-ΔVP5, ...
The effect of agonistic encounters on aggressive response in socially isolated Siamese fighting fish, Betta splendens
(2003-12-16)
Male Siamese fighting fish were held for 7 to 10 weeks either in visually-social conditions (interact aggressively with a mirror image for 2 min, three times a week) or as visually-isolated fish (no aggression, saw only ...
Evaluation of Lef1 Transcription Factor in Mammalian Preimplantation Embryos
(2007-09-14)
The first lineage differentiation of cells during pre-implantation embryo development is critical for continued embryonic growth. Though several transcription factors (TFs) have been identified that are involved in this ...
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 ...
Priming with Oral Progestin Before Ovulation Induction Facilitates Ovarian Function in the Cat (Felis catus)
(2007-11-21)
Artificial insemination (AI) has been developed in multiple felid species as a tool for retaining gene diversity in threatened or endangered populations. Yet, pregnancy success remains low (< 5%) following AI in most ...
EPIDEMIOLOGIC ANALYSIS OF RISK FACTORS FOR LOCAL DISAPPEARANCES OF NATIVE RANID FROGS IN ARIZONA
(2005-08-11)
This study used epidemiologic case-control methodology to examine habitat and environmental factors contributing to amphibian declines in Arizona. Risk factors were compared between sites where frogs disappeared (cases) ...
Characterization of Glucocorticoid-Induced Changes in Gene Expression in the Embryonic Pituitary Gland
(2006-04-27)
We have previously shown that corticosterone (CORT) can induce premature differentiation of somatotrophs in the chicken embryo. CORT induction of GH mRNA is indirect, in that protein synthesis inhibition blocks its inducing ...
