Feed Values For Annual Forages In Western Nebraska, Burton A. Weichenthal, David D. Baltensperger, Kenneth P. Vogel Jan 2004

Feed Values For Annual Forages In Western Nebraska, Burton A. Weichenthal, David D. Baltensperger, Kenneth P. Vogel

Nebraska Beef Cattle Reports

Forage quality testing was completed on annual forages grown during 1998 and/or 1999. Included were spring cereals, legumes and summer annuals like sorghum and millets. Using a single cut harvest system when the majority of summer annuals had produced seed heads, crude protein (CP) was generally more than 8% and total digestible nutrients (TDN) more than 63% of dry matter. Annual legumes had 12 to 18% CP and more than 63% TDN. Pearl and irrigated foxtail millets had higher crude protein levels than sorghum forages, but nitrate levels were also higher. Some mineral contents varied by location and associated management.

Assessment Of Thermal Infrared Detection Rates Using White-Tailed Deer Surrogates, Robert E. Kissell Jr., Philip A. Tappe Jan 2004

Assessment Of Thermal Infrared Detection Rates Using White-Tailed Deer Surrogates, Robert E. Kissell Jr., Philip A. Tappe

Journal of the Arkansas Academy of Science

As thermal infrared imaging technology has improved, it has increasingly been used for estimating sizes of wildlife populations. The greatest bias of thermal infrared surveys is the lack of known detection rates to adjust for visibility bias. As with visual surveys, a measure of detection rate is needed to provide unbiased estimates. We assessed the detection rate of white-tailed deer (Odocoileus virginianus) using a thermal infrared sensor (1.2 - 5.9 /an) from an aerial platform. Similar characteristics between thermal signatures of people and deer allowed us to use people in a reclined or horizontal position as surrogates for deer. We …

Human Rabies Post-Exposure Treatment In Arkansas, 1994-2000, D. Blake Sasse Jan 2004

Human Rabies Post-Exposure Treatment In Arkansas, 1994-2000, D. Blake Sasse

Journal of the Arkansas Academy of Science

The Arkansas Department of Health recorded 118 incidents where humans in Arkansas were treated following exposure to confirmed rabid animals from 1994-2000. Domestic species accounted for 64% of incidents and 76% of total human exposures with the ratio of human exposures per rabid animal 17 times higher for domestic animals than wild animals. Records of 218 cases of human exposure to potentially rabid wild animals during this period were also examined to determine method of contact. While 72% of cases involving raccoons (Procyon lotor), skunks (Mephitis mephitis and Spilogale putorius), and foxes (Urocyon cinereoargenteus and Vulpes vulpes) were initiated by …

The Role Of Farm Dams As Refugia For Aquatic Invertebrates In A Salinised Landscape, South Western Australia, Jean-Michel Benier Jan 2004

The Role Of Farm Dams As Refugia For Aquatic Invertebrates In A Salinised Landscape, South Western Australia, Jean-Michel Benier

Theses: Doctorates and Masters

In a salinised landscape farm dams may represent the last truly freshwater surface resource, and therefore provide refuge habitats for the biota of wetlands affected by increasing salinity. One wetland threatened by increased salinity in south-west Western Australia is Lake Toolibin. It is listed as a Wetland of International Importance under the Ramsar Convention in recognition of its high conservation value, and remediation actions to halt (and possibly reverse) further increases in salinity are being undertaken at this wetland. Farm dams act as aquatic refugia if they convey resistance and/or resilience to the biotic communities of a disturbed habitat. This …

Response Of Small Mammal Populations To Fescue Hayfield Conversion To Native Warm Season Grasses In Bath County, Virginia, Michael T. Mengak Jan 2004

Response Of Small Mammal Populations To Fescue Hayfield Conversion To Native Warm Season Grasses In Bath County, Virginia, Michael T. Mengak

Virginia Journal of Science

I investigated the effect on small mammal populations of converting an existing fescue (Festuca arundinacea) hayfield to switchgrass (Panicium virgatum) on the George Washington National Forest at Hidden Valley in Bath County, Virginia. Native warm season grasses are thought to provide better habitat than fescue pastures for Northern Bobwhite (Colinus virginianus) and several species of grassland birds as well as herbivorous small mammals. I established one live-trapping grid and conducted trapping (pre-treatment) in both the switchgrass (treatment) and the fescue (control) field in March and May 1997. The treatment field was sprayed with glyphosate …

The Chick Embryo Amnion As An In Vitro Culture System For Ivf And Nt Embryos, Tonya Renea Davidson Jan 2004

The Chick Embryo Amnion As An In Vitro Culture System For Ivf And Nt Embryos, Tonya Renea Davidson

LSU Doctoral Dissertations

Calving rates are significantly reduced following in vitro production of embryos. Thus, if a technique could be developed that would increase calving rates by as little as one viable offspring, significant research advances could be made. Therefore, in a series of experiments, the efficiency and quality of culturing IVP bovine embryos in the amnion of a domestic chicken egg was tested. In Experiment I, by culturing IVP bovine embryos in the chick amnion (day 4 to 7 of incubation) it was discovered that there was no significant difference in blastocyst rates compared with controls. In Experiment II, it was shown …

Somatic Cell Interspecies Nuclear Transfer, Marina Julia Sansinena Jan 2004

Somatic Cell Interspecies Nuclear Transfer, Marina Julia Sansinena

LSU Doctoral Dissertations

The low efficiency of the nuclear transfer (NT) procedure requires large number of oocytes to produce embryos and live offspring. A series of experiments were conducted to evaluate the ability of the bovine cytoplast to reprogram nuclei from horses and llamas. In a preliminary study, equine oocytes from small (<20mm diameter) follicles were either pretreated with roscovitine or placed in maturation (IVM only) prior to NT. Roscovitine pretreatment did not improve nuclear maturation rates (roscovitine pretreatment 57% vs. IVM only 66%) and no fusion was obtained from roscovitine-pretreated oocytes after NT. Another preliminary study was conducted with the objective to produce llama NT embryos and to compare their development in two in vitro culture conditions (G1.2® vs. CR1aa). No difference was found in the number of embryos cleaved after 2 d of culture. This resulted in the first scientific report of somatic cell NT, in vitro culture and transfer of NT embryos in the llama. In the next experiment, adult horse and llama fibroblasts were injected into enucleated cow oocytes. The results showed the cow cytoplasm is capable of partially reprogramming nuclei from other species and support mitotic divisions. However, this study also showed a consistent embryonic developmental arrest at the 8- to 16- cell stage when horse or llama donor cells were used as donor nuclei. When a more closely related species of donor cell (banteng) and recipient oocyte (domestic cattle) were used for NT, no embryonic developmental arrest was found. Embryos progressed to achieve high blastocyst rates (banteng male cell line 28% vs. banteng female cell line 15%). Two banteng interspecies NT pregnancies were established and subsequently lost from the banteng male cell line. In the final study, the effect of a mixed mitochondrial population (heteroplasmy) on early embryonic development was investigated. Ooplasmic transfer performed in combination with NT procedure indicated presence of foreign mitochondria clustered in a small portion of the cytoplasm in early stages of embryo development. When goat ooplasm was transferred into interspecies (cow oocyte-goat donor cell) NT embryos, fusion and cleave rates were reduced suggesting an increased level of heteroplasmy or nuclear-ooplasmic incompatibilities.

Zebra Mussel And Fouling Problems In The Euphrates Basin, Alaeddi̇n Bobat, Mehmet Oğuz Hengi̇rmen, Walter Zapletal Jan 2004

Zebra Mussel And Fouling Problems In The Euphrates Basin, Alaeddi̇n Bobat, Mehmet Oğuz Hengi̇rmen, Walter Zapletal

Turkish Journal of Zoology

The Zebra mussel, Dreissena polymorpha Pallas, is one of the most important fouling organisms in freshwater ecosystems. Infestations by Zebra mussels have caused chronic problems in both raw water(incoming water into facilities) intakes and man-made structures such as water treatment facilities, power plants and industrial facilities. In the mid-1980s, this pest, a species nonindigenous to North American freshwaters, was introduced into the Great Lakes of North America. This introduction probably occurred by means of the ballast water of a transoceanic ship, and concern has focused again on this nuisance and its impact. Recently, the Zebra mussel, a species native to …

Implications Of Locus Specific Microevolution Inferred By Genetic Distances Between Two Local Populations Of Drosophila Melanogaster From Turkey, Ergi̇ Deni̇z Özsoy Jan 2004

Implications Of Locus Specific Microevolution Inferred By Genetic Distances Between Two Local Populations Of Drosophila Melanogaster From Turkey, Ergi̇ Deni̇z Özsoy

Turkish Journal of Zoology

The standard genetic distances were calculated with 3 allozyme loci in 2 local populations of Drosophila melanogaster from Turkey. One of the distances, i.e. obtained with alcohol dehydrogenase (Adh), was completely different from the distances with the other 2 allozyme loci, glycerophosphate dehydrogenase (\alphaGpdh) and cytosolic malate dehydrogenase (Mdh1), leading to a statistically significant inflation in the cumulated distance value obtained over the 3 loci. It is shown that this final significant value was caused by the significant difference in allelic frequencies at the Adh loci across local populations. Implications of the different genetic distances in 2 local populations are …
