The Effects Of Different Organic Pastures On Dairy Heifer Growth And Development, 2020 Utah State University
The Effects Of Different Organic Pastures On Dairy Heifer Growth And Development, Jacob A. Hadfield
All Graduate Theses and Dissertations
Raising dairy heifers in a certified organic setting can be difficult for producers. Conventionally, heifers are raised in a confined setting, and fed a total mixed ration (TMR) that is balanced daily to contain all the needed nutrients for developing heifers. Organic producers can use a TMR in their operations, but due to high organic feed costs, many choose to raise their heifers in pasture-based systems. While pasture-based systems may lower costs, heifers on pasture commonly have lower rates of gain, which can be financially burdensome to producers. Grass-legume pastures may help improve rates of gain in heifers on pasture-based ...
Influence Of Forage Diversity And Condensed Tannins On Livestock Foraging Behavior, Production And Environmental Impact, Sebastian P. Lagrange
All Graduate Theses and Dissertations
Eating a combination of forages with different chemistries (i.e., nutrients, beneficial compounds such as tannins) may enhance ruminant nutrition and reduce environmental impacts relative to eating single forages. I explored the influence of offering sheep and cattle all possible combinations of tanniferous (i.e., plants with tannins; birdsfoot trefoil, sainfoin) and non-tanniferous legumes (i.e., plants without tannins; alfalfa) or their monocultures on animal performance, behavior, and methane and nitrogen (N) emissions. Offering choices among these legumes to penned sheep improved intake and diet digestibility relative to feeding monocultures. Mixtures selected by sheep were better digested than mixtures containing ...
Comparative Analysis Of Small Non-Coding Rna And Messenger Rna Expression In Somatic Cell Nuclear Transfer And In Vitro-Fertilized Bovine Embryos During Early Development Through The Maternal-To-Embryonic Transition, 2020 Utah State University
Comparative Analysis Of Small Non-Coding Rna And Messenger Rna Expression In Somatic Cell Nuclear Transfer And In Vitro-Fertilized Bovine Embryos During Early Development Through The Maternal-To-Embryonic Transition, Jocelyn Marie Cuthbert
All Graduate Theses and Dissertations
Cloning animals using somatic cell nuclear transfer (scNT) was first successfully demonstrated with the birth of Dolly the sheep, but the process of cloning remains highly inefficient. By improving our understanding of the errors that may occur during cloned cattle embryo development, we could obtain a greater understanding of how specific molecular events contribute to successful development. The central dogma of biology refers to the process of DNA being transcribed into messenger RNA (mRNA) and the translation of mRNA into proteins, which ultimately carry out the functions encoded by genes. The epigenetic code is defined as the array of chemical ...
The Effects Of Gene Therapy In An Ovine Osteoarthritis Model, 2020 Utah State University
The Effects Of Gene Therapy In An Ovine Osteoarthritis Model, Crystal Collier
All Graduate Theses and Dissertations
Humans rely on the health of their joints for stability and mobility in daily life. In a normal, healthy functioning joint, complex processes maintain joint tissues, including remodeling, lubrication, and immune function among many other tasks. Osteoarthritis (OA) is the most common joint disorder in the U.S. It becomes most prevalent in adults 60+ years of age and causes decreased mobility, discomfort, and in some cases, excruciating pain. In the biological processes of osteoarthritis, the metalloproteinase enzymes responsible for the degeneration of cartilage are upregulated. The inhibitors of metalloproteinase activity are known as Tissue Inhibitor of Metalloproteinases (TIMPs), which ...
Enhancing The Production And Sustainability Of Pasture-Fed Beef Using Non-Traditional Legume Forages, 2020 Utah State University
Enhancing The Production And Sustainability Of Pasture-Fed Beef Using Non-Traditional Legume Forages, Andrea I. Bolletta
All Graduate Theses and Dissertations
Despite the increasing worldwide demand for beef as a protein source, consumers are concerned about the sustainability of ruminant production systems. Their main concerns are animal welfare for feedlot-fed animals, greenhouse gas (GHG) emissions, global warming and worker safety. Traditional feedlot-based beef production systems have been associated with locally greater levels of soil, water and air contamination, as well as the overuse of antibiotics and growth hormones. The use of legume pastures such as cicer milkvetch (CMV) and birdsfoot trefoil (BFT), which fix their own nitrogen (N) and often contain beneficial secondary compounds such as tannins and provide for rapid ...
Evaluating The Effect Of The Removal Of Non-Native Trout In Two High Elevation Tributary Streams In The Intermountain West, Clint Brunson
All Graduate Plan B and other Reports
Native fish species such as Bonneville Cutthroat Trout (BCT) require cold, clear, well-connected streams for spawning and rearing as well as access to complimentary habitats. Increasing river temperatures and lower water flows may have allowed non-native Brown Trout (BNT) to migrate into higher elevation pristine streams. Additionally, anthropogenic actions such as stocking non-native Brown and Brook (BKT) and Rainbow Trout (RBT) for angling opportunities impact BCT. Invasion of these tributaries by non-native species may reduce or eliminate cutthroat trout by predation, competition, displacement, genetic suppression, and exclusion. A seven-fold increase in BNT numbers of 50 to 350 from 2017 to ...
Metagenomic, Viral And Host Genetic Analyses Of Congenital Tremor In Pigs, 2020 University of Nebraska - Lincoln
Metagenomic, Viral And Host Genetic Analyses Of Congenital Tremor In Pigs, Kylee Sutton
Dissertations and Theses in Biological Sciences
The Pestivirus genus contains several viral species having a major impact on the livestock species. While there were only four major pestiviral species for a time, recent metagenomic sequencing approaches identified additional species, such as atypical porcine pestivirus (APPV). Congenital tremor was first identified almost a hundred years ago and since still has an impact on swine health. There are two main types of congenital tremor, type A and B, with type A congenital tremor further subcategorized based on causative agent. Until recently, type A-II congenital tremor did not have a known cause. Recent viral sequencing of affected samples, including ...
Snowy Plover Activity In The Central Platte River Valley In May 2019, 2020 Platte River Whooping Crane Maintenance Trust
Snowy Plover Activity In The Central Platte River Valley In May 2019, Bethany L. Ostrom, Andrew J. Caven, Jenna M. Malzahn, Alyx Vogel
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
During five of eight site visits between 14 and 27 May 2019 we detected up to four Snowy Plovers (Charadrius nivosus nivosus) in the Central Platte River Valley (CPRV) near Mormon Island, Hall County, Nebraska, and recorded their behavior using an instantaneous scan sampling approach. We recorded loafing (47%), foraging (43%), mating (4%), flying (4%), and external threat (1%) related behavior. Most notably, we documented a copulation event on 23 May. During the 10-day span from 14 to 23 May when Snowy Plovers were detected, river stage and discharge were near median levels, but from 23 to 27 May river ...
Consider The Agent In The Arthropod, 2020 New College of Florida
Consider The Agent In The Arthropod, Nicolas Delon, Peter Cook, Gordon Bauer, Heidi Harley
Whether or not arthropods are sentient, they can have moral standing. Appeals to sentience are not necessary and retard progress in human treatment of other species, including invertebrates. Other increasingly well-documented aspects of invertebrate minds are pertinent to their welfare. Even if arthropods are not sentient, they can be agents whose goals—and therefore interests—can be frustrated. This kind of agency is sufficient for moral status and requires that we consider their welfare.
Property Rights And The Efficient Extraction Of Common Pool Resources: Evidence From West Coast Groundfish, Keith S. Evans, Carl Lian, Quinn Weninger
Economics Working Papers
This paper evaluates harvesting efficiency for the universe of vessels that participated in the West Coast groundfish trawl fishery two years prior to and six years following the intro- duction of an individual fishing quota (IFQ) regulation. Our economic efficiency measures control for delayed fleet restructuring and potentially confounding effects of unobserved stock abundance and/or other time-varying factors. We find that under IFQs, redundant vessel capital exited the groundfish fishery at a rate of 5.77% per year, and resource rent increased at a rate of 6.02% per year. Annual resource rent is estimated at $31.26 million ...
Feeder Cattle Future Price Spreads: Opportunities To Hedge?, 2020 University of Nebraska - Lincoln
Feeder Cattle Future Price Spreads: Opportunities To Hedge?, Elliott James Dennis
Extension Farm and Ranch Management
Feeder cattle future price spreads across all months have recovered to near pre-COVID-19 levels as quarantine restrictions and packing plant capacity issues have been mostly sorted out. For example, for the week of July 17, 2010 [sic], prices reached levels not seen since the beginning of March 2020. Pasture and corn progress are two factors that have the potential to push prices lower in the next coming months. Given current market conditions, producers have some options to lock in a margin.
The Lives, Lore, And Literature Of Cranes: A Catechism For Crane Lovers, 2020 University of Nebraska-Lincoln
The Lives, Lore, And Literature Of Cranes: A Catechism For Crane Lovers, Paul A. Johnsgard, Thomas D. Mangelsen
This book provides basic information on cranes that should be of interest and importance to crane-loving birders (“craniacs”) as well as to ornithologists and wildlife managers. Primary consideration is given to the sandhill and whooping cranes, but all 13 of the Old World cranes are also discussed. Special consideration is given to the relative abundance and conservation status of all of the world’s species, of which nearly half are declining and a few are in real danger of long-term survival. More than 80 refuges and preserves in the United States and Canada, where the best chances of seeing cranes ...
Effects Of Freshwater Crayfish On Influenza A Virus Persistence In Water, 2020 National Wildlife Research Center, Fort Collins
Effects Of Freshwater Crayfish On Influenza A Virus Persistence In Water, J. Jeffrey Roots, Jeremy W. Ellis, Susan A. Shriner
USDA National Wildlife Research Center - Staff Publications
Several investigations have recently assessed the ability of some aquatic invertebrates to act as tools for avian influenza A virus (IAV) surveillance as well as their potential role(s) in IAV ecology. Because of this, as well as the high IAV seroprevalence rates noted in select mesocarnivores that commonly inhabit aquatic and semi-aquatic habitats, we evaluated the effects that freshwater crayfish have on IAV in water at three dose levels and monitored for the presence of IAV in crayfish tissues (gill and green gland) and haemolymph at multiple time points. At relatively high, medium 432 and low (approximately 10 , 10 ...
Five New Species Of Euscorpius Thorell, 1876 (Scorpiones: Euscorpiidae) From Albania, Greece, North Macedonia, And Serbia, František Kovařík, František Šťáhlavský
Five new species are described: Euscorpius bonacinai sp. n. (Albania), E. janstai sp. n. (North Macedonia), E. kabateki sp. n. (Greece), E. sadileki sp. n. (Serbia), and E. scheraboni sp. n. (Greece), fully complemented with color photographs. New species are distinguished from all other species of the genus on the basis of five taxonomic characters. Two other new characters, shape of the pedipalp chela fingers and number of chromosomes, are presented and discussed. In addition to the analyses of external morphology, we also describe karyotypes of two species: E. janstai sp. n. (2n=112) and E. sadileki sp. n. (2n ...
Wild Mice With Different Social Network Sizes Vary In Brain Gene Expression, 2020 Chapman University
Wild Mice With Different Social Network Sizes Vary In Brain Gene Expression, Patricia C. Lopes, Barbara König
Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
Appropriate social interactions influence animal fitness by impacting several processes, such as mating, territory defense, and offspring care. Many studies shedding light on the neurobiological underpinnings of social behavior have focused on nonapeptides (vasopressin, oxytocin, and homologues) and on sexual or parent-offspring interactions. Furthermore, animals have been studied under artificial laboratory conditions, where the consequences of behavioral responses may not be as critical as when expressed under natural environments, therefore obscuring certain physiological responses. We used automated recording of social interactions of wild house mice outside of the breeding season to detect individuals at both tails of a distribution ...
Identification And Phylogenetic Analysis Of Channa Species From Riverine System Of Pakistan Using Coi Gene As A Dna Barcoding Marker, 2020 Department of Zoology, Quaid i Azam University Islamabad
Identification And Phylogenetic Analysis Of Channa Species From Riverine System Of Pakistan Using Coi Gene As A Dna Barcoding Marker, Muhammad Kamran, Atif Yaqub, Naila Malkani, Khalid Mahmood Anjum, Muhammad Nabeel Awan, Hamed Paknejad
Journal of Bioresource Management
Channa are the freshwater and important food fish species in Pakistan belonging to family Channidae. However, identification and phylogenetic analysis based on molecular tools of these species in Pakistan was not well known. Herein, the current investigation was conceptualized, which dealt with mitochondrial DNA sequences from three geographically distinct populations of this species from Pakistan’s water system. DNA from fin tissues was extracted. COI region of mtDNA was amplified using universal primers for fish. PCR products were sequenced. Phylogenetic analysis conducted in the present study, i.e. neighbor-joining (NJ) cladogram, maximum likelihood, K2P genetic divergence and histogram suggests that ...
Avoiding Anthropocentrism In Evolutionarily Inclusive Ethics, 2020 John Carroll University
Avoiding Anthropocentrism In Evolutionarily Inclusive Ethics, Simon Fitzpatrick
Mikhalevich & Powell are to be commended for challenging the “invertebrate dogma” that invertebrates are unworthy of ethical concern. However, developing an evolutionarily inclusive ethics requires facing some of the more radical implications of rejecting hierarchical scala naturae and human-centered conceptions of the biological world. In particular, we need to question the anthropocentric assumptions that still linger in discussions like these.
Zones Of Precaution, 2020 London School of Economics and Political Science
Zones Of Precaution, Jonathan Birch
My commentary focusses on Mikhalevich & Powell’s criticisms of the Animal Sentience Precautionary Principle. I emphasize the pragmatic nature of my rationale for proposing that, rather than extending the scope of animal welfare protection on a species-by-species basis, we should be willing to protect entire Linnaean orders on the basis of evidence from a single species.
