Department of Animal Science: Faculty Publications

Two experiments evaluated prebreeding target BW or progestin exposure for heifers developed lighter than traditional recommendations. Experiment 1 evaluated the effects of the system on heifer performance through subsequent calving and rebreeding over 3 yr. Heifers (229 kg) were assigned randomly to be developed to 55% of mature BW (299 kg) before a 45-d breeding season (intensive, INT; n = 119) or 50% of mature BW (272 kg) before a 60-d breeding season (relaxed, RLX; n = 142). Prebreeding and pregnancy diagnosis BW were greater (P ≤ 0.006) for INT than RLX heifers. Overall pregnancy rate did not differ (88.4%; …

Vascular Endothelial Growth Factor (Vegf) Isoforms May Regulate Sex-Specific Vascular Development, Cord Formation And Follicle Progression In Developing Gonads, Andrea S. Cupp, Rebecca C. Bott, Renee M. Pohlmann, Robin A. Ten Broeck, Debra T. Clopton

Department of Animal Science: Faculty Publications

The ratio of VEGF angiogenic to anti-angiogenic isoforms appears to determine different biological functions in reproduction. Reduced amounts of angiogenic VEGF isoforms inhibit testis sex-specific vasculature and normal cord formation in organ cultures while reduction of inhibitory isoforms increased vasculature and perturbed cords. In the female, using peri-natal ovarian cultures, inhibition of angiogenic VEGFisoforms reduced vascular development and inhibited follicle progression while conversely reductions in inhibitory isoforms or increases in angiogenic isoforms enhanced follicle development. Thus, regulation of the Vegfa gene to produce angiogenic or anti-angiogenic isoforms may be a mechanism to alter sex-specific vascular development, formation of seminiferous cords, …

Cattle Code: Coproduct Optimizer Decision Evaluator, Crystal D. Buckner, Darrell Mark, Virgil R. Bremer, Galen E. Erickson Jan 2008

Cattle Code: Coproduct Optimizer Decision Evaluator, Crystal D. Buckner, Darrell Mark, Virgil R. Bremer, Galen E. Erickson

Department of Animal Science: Faculty Publications

Expansion of the corn-based ethanol industry in recent years has resulted in a growing supply of coproduct feeds. These coproducts result in significant improvements in cattle performance and are often priced lower than corn on a dry matter basis. Along with these benefits to feeding ethanol coproduct feeds, cattle feeders must also account for additional transportation costs to originate the coproducts and for added expenses to handle, mix, and deliver the feed ration within the feedlot. An economic budget model, called Cattle CODE, was created to help feeders, nutritionists, and Extension educators evaluate these nonlinear effects across unique feeding situations.

Board-Invited Review: Use Of Distillers By-Products In The Beef Cattle Feeding Industry, Terry J. Klopfenstein, Galen E. Erickson, Virgil R. Bremer Jan 2008

Board-Invited Review: Use Of Distillers By-Products In The Beef Cattle Feeding Industry, Terry J. Klopfenstein, Galen E. Erickson, Virgil R. Bremer

Department of Animal Science: Faculty Publications

The ethanol industry is expanding rapidly. This expansion in production of renewable energy also increases production of by-products. These byproducts, primarily distillers grains plus solubles (DGS), are utilized very efficiently by ruminants. When the starch in corn is fermented to produce ethanol, the remaining nutrients (protein, fat, fiber) are concentrated about 3-fold. Whereas DGS is an excellent protein source for ruminants, the large supply and the price relative to corn make DGS an attractive energy source as well. This is especially important with reduced availability and higher price of corn because of demand by the ethanol industry. A meta-analysis of …

Distribution And Taxonomic Status Of Tarantulas In Arkansas(Theraphosidae: Aphonopelma), Michael D. Warriner Jan 2008

Distribution And Taxonomic Status Of Tarantulas In Arkansas(Theraphosidae: Aphonopelma), Michael D. Warriner

Journal of the Arkansas Academy of Science

The genus Aphonopelma (Theraphosidae) is marked by a dearth of distributional data and a problematic taxonomy. To develop occurrence information for the genus in Arkansas, I conducted a citizen-science based survey augmented by field work and examination of museum collections. Results of these efforts yielded a significant amount of data that enabled the construction of a county level map of Aphonopelma distribution in Arkansas; a resource hitherto unavailable. Three Aphonopelma species have been described as occurring in Arkansas: A. baergi, A. hentzi, and A. odelli. Specimens were collected from Arkansas and Oklahoma to evaluate taxonomic and historical issues concerning the …

Effects Of Alcohol And Training On Exercise Performance And Muscle Recovery Biochemistry In The Brown Anole (Anolis Sagrei), Maryclaire Mcgovern Jan 2008

Effects Of Alcohol And Training On Exercise Performance And Muscle Recovery Biochemistry In The Brown Anole (Anolis Sagrei), Maryclaire Mcgovern

Honors Theses

Contrary to previous research, training may improve exercise performance in a lizard, the brown anole. A brief, two-week training period resulted in increased performance speed and distance before exhaustion in trained lizards. Trained lizards were also able to more effectively use leg glycogen stores, however each of these improvements were not found in lizards treated with alcohol. Liver glycogen concentrations were also lower in alcohol-treated lizards, and patterns of liver glycogen concentrations during recovery indicate some hepatic lactate gluconeogenesis.

Animal, Dairy, and Veterinary Science Faculty Publications

Phenothiazine and derivatives were tested for inhibition of SARS-CoV replication. Phenothiazine slightly inhibited SARS-CoV replication in a neutral red (NR) uptake assay. Adding a propylamino group to give promazine reduced virus yields (VYR assay) with an EC90 = 8.3 ± 2.8 μM, but without selectivity. Various substitutions in the basic phenothiazine structure did not promote efficacy. Phenazine ethosulfate was the most potent compound by VYR assay (EC90 = 6.1 ± 4.3 μM). All compounds were toxic (IC50 = 6.6–74.5 μM) except for phenoxathiin (IC50 = 858 ± 208 μM) and 10-(alpha-diethylamino-propionyl) phenothiazine·HCl (IC50 = 195 ± 71.2 μM). Consequently, none …

Cranial Anatomy And Taxonomy Of Dolichorhynchops Bonneri New Combination, A Polycotylid (Sauropterygia: Plesiosauria) From The Pierre Shale Of Wyoming And South Dakota, F. Robin O’Keefe

Biological Sciences Faculty Research

The taxonomic identity of two well-preserved polycotylid plesiosaur skeletons from the Pierre Shale of far northern Wyoming and southern South Dakota has been controversial since their discovery. Originally referred to Dolichorhynchops osborni, the material was almost immediately christened Trinacromerum bonneri Adams 1997; more recently the material has been referred toPolycotylus. Recent preparation of the well-preserved skull of one specimen permits detailed examination of the cranial morphology of this animal for the first time, and allows for its inclusion in a cladistic analysis of the Polycotylidae. This analysis reveals a stable sister-taxon relationship with Dolichorhynchops osborni. However, …

Optimal Data Partitioning And A Test Case For Ray-Finned Fishes (Actinopterygii) Based On Ten Nuclear Loci, Chenhong Li, Guoqing Lu, Guillermo Orti Jan 2008

Optimal Data Partitioning And A Test Case For Ray-Finned Fishes (Actinopterygii) Based On Ten Nuclear Loci, Chenhong Li, Guoqing Lu, Guillermo Orti

Biology Faculty Publications

Data partitioning, the combined phylogenetic analysis of homogeneous blocks of data, is a common strategy used to accommodate heterogeneities in complex multilocus data sets. Variation in evolutionary rates and substitution patterns among sites are typically addressed by partitioning data by gene, codon position, or both. Excessive partitioning of the data, however, could lead to overparameterization; therefore, it seems critical to define the minimum numbers of partitions necessary to improve the overall fit of the model. We propose a new method, based on cluster analysis, to find an optimal partitioning strategy for multilocus protein-coding data sets. A heuristic exploration of alternative …
