Evaluation Of Growth Performance, Carcass Characteristics, And Methane And Co2 Emissions Of Growing And Finishing Cattle Raised In Extensive Or Partial-Intensive Cow-Calf Production Systems, Zachary E. Carlson, Levi J. Mcphillips, Rick R. Stowell, Galen E. Erickson, Mary E. Drewnoski, Jim C. Macdonald

Department of Animal Science: Faculty Publications

An experiment was conducted over 2 yr to measure performance and greenhouse gas (GHG) emissions of weaned calves from two cow-calf production systems. Crossbred steers and heifers (n = 270, initial body weight (BW) = 207 kg, SD = 35) were used in a randomized complete block design, with treatments applied to the cow-calf system. Treatments were: 1) a traditional system consisting of April to June calving with smooth bromegrass pasture and grazed corn residue as forage resources (TRAD); 2) an alternative system consisting of July to September calving utilizing partial-drylot feeding, summer-planted oats, and corn residue grazing (ALT). …

Our obligation is to make sure we are effectively utilizing science to meet the objectives of the Platte River Whooping Crane Maintenance Trust (1981) laid out in its charter “to rehabilitate and preserve a portion of the habitat for Whooping Cranes and other migratory birds in the Big Bend reach of the Platte River between Overton and Chapman (i.e., Central Platte River Valley), Nebraska”. The original declaration is aimed at maintaining “the physical, hydrological, and biological integrity of the Big Bend area as a life-support system for the Whooping Crane and other migratory species that utilize it.” It was clear …

Fish And Invertebrate Community And Trophic Structure In The Gulf Of Mexico Coastal Plains Watersheds Across Varying Hydrologic Connectivity., Erin Elizabeth Thayer

LSU Doctoral Dissertations

Subtropical Northern Gulf of Mexico coastal plains watersheds tend to have mild seasonal temperature, low topography, and fine, mostly homogenous substrate sizes; these watersheds may not follow fish and invertebrate community patterns predicted by established lotic paradigms because those paradigms tend to describe communities in either temperate or tropical regions. However, the bases of most generally accepted lotic paradigms involve evaluation of allochthonous and autochthonous contributions to lotic ecosystems via three hydrologic connectivity dimensions including vertical (hyporheic and shallow groundwater), lateral (floodplain), and longitudinal (upstream and downstream). My dissertation goals were to explore these three dimensions within Louisiana coastal plains …

Searching For The Soldier Pheromone: Behavioral Effects Of Soldiers And Soldier-Produced Chemicals In The Formosan Subterranean Termite, Coptotermes Formosanus (Blattodea: Rhinotermitidae)), Joseph Mccarthy

LSU Master's Theses

The Formosan subterranean termite, Coptotermes formosanus, is a eusocial insect and an invasive urban pest. Colonies function through a division of labor among castes (i.e., queens and kings, workers, and soldiers). Though soldiers are energetically expensive to maintain, C. formosanus has a relatively large soldier caste (~10% of the colony). Soldiers are physically unable to collect food or build tunnels but are regularly found with foraging workers. In some species, soldiers influence the worker foraging behavior. In C. formosanus, aside from defense, the roles soldiers play remains unknown. In this study, we determined if soldiers influence …

Ecology And Evolution Of Social Information Use, Clare T. M. Doherty

Dartmouth College Ph.D Dissertations

Sociality is a strategy many animals employ to cope with their environments, enabling them to survive and reproduce more successfully than would otherwise be possible. When navigating their environments and making decisions, social individuals often use information provided by conspecifics (in the form of social cues and signals), thereby increasing the scope and reliability of the information they can gather. However, social information use may be influenced by many factors, including key differences in context across the physical and social environment. My thesis asks and answers a series of questions regarding the trade-offs in social information use across different contexts, …

Chinese Consumers’ Attitudes Toward Animal Welfare: Behaviors, Beliefs, And Responses To Messaging, Jo Anderson

General - Animal Protection

Despite being comparatively neglected until recently, the suffering of animals in Asia is starting to command more attention from global animal advocacy activists. In particular, as the largest country in the world by both human and farmed animal population, and among the largest when measured by economy and land mass, China plays a central role here. However, the key question of how best to improve outcomes for farmed animals in China remains difficult to answer, due to the recency of the movement and a comparative lack of research on the topic.

Although China’s per capita meat consumption is lower than …

Fall Field Report, August-November 2022, W. Ross Silcock

Nebraska Bird Review

All in all, this was a fairly uneventful fall season, although even uneventful seasons have their share of oddities and variations from the norm. A noteworthy event was a fire that took out much of the brushy habitat in Carter Canyon, Scotts Bluff Co (see photo on following page). It will be interesting to read upcoming spring reports to see what effect the fire might have had on numbers of birds that frequent brushy areas, like towhees and buntings. Optimistically, fires have attracted rare woodpeckers, with first to arrive Black-backed, which would be a first documented Nebraska record, and typically …

Three experiments evaluated the effects of three corn silage hybrids, inclusion, and nutrient digestibility in growing and finishing diets. The three hybrids tested included a control (CON), a hybrid containing a brown midrib (bm3) trait (BM3), and an experimental bm3 hybrid with the soft endosperm trait (BM3-SOFT). Experiment 1 utilized 360 crossbred steers (body weight [BW] = 334; SD = 25 kg) to evaluate inclusion of silage in a finishing diet at (15% or 45% of diet dry matter [DM]) and silage hybrid (CON, BM3, or BM3-SOFT). Experiment 2 and 3 utilized 216 crossbred steers (BW = 324; SD = …

Association Of A Green Tea Extract With Serum Immunoglobulin G Status And Neonatal Vitality In Newborn Dairy Calves, M. E. Reis, Melissa C. Cantor, C. M. M. Bittar, Joao H. C. Costa

Animal and Food Sciences Faculty Publications

Poor vigor at birth has been associated with reduced IgG absorption from colostrum and a reduced vitality in neonatal dairy calves. Some natural compounds, such as green tea extract, may improve vitality in compromised calves. The objective of this randomized controlled trial was to evaluate the potential of supplementing a green tea extract (15 mL) to calves to improve vigor and activity behavior for the first 72 h postnatal. Also, this study aimed to investigate the influence of green tea extract supplementation on calf serum IgG concentration and the apparent efficiency of absorption (AEA) of colostral IgG. Holstein calves (n …

Identifying Early-Life Behavior To Predict Mothering Ability In Swine Utilizing NuTrack System, Savannah Gabrielle Millburn

Department of Animal Science: Dissertations, Theses, and Student Research

Early recognition of indicator traits for swine reproduction and longevity supports economical selection decision making. Gilt activity is a key variable impacting a sow’s herd life and productivity. The purpose of this study was to examine early- life behaviors contributing to farrowing traits including gestation length (GL), number born alive (NBA), number weaned (NW), and herd life (HL). Herd life was a binary trait representing if a gilt was culled after one parity. Beginning at approximately 20 weeks of age, video recordings were taken on 480 gilts for 7 consecutive days and processed using the NUtrack system. Activity traits …

Striving To Be Resilient: The Role Of Crop-Poultry Integrated System As A Climate Change Adaptation Strategy In Semiarid Eastern Kenya, Kelvin Mulungu, Daniel Kangogo

All Peer-Reviewed Publications

Climate change continues to pose significant challenges to food security and livelihoods of smallholder farmers specifically in semi-arid regions. One approach that holds prospects for climate risk management is climate-smart agriculture (CSA). CSA has concentrated on crop practices with little attention to livestock especially indigenous (village) chickens as a potential practice that can be combined with crop agriculture. This study considers the adoption of three CSA practices: improved maize seeds (IS), soil management (SM), indigenous chicken (IC) enterprise and their various combinations. Using survey data collected from 300 farming households in semiarid Kenya, we estimate the impact of integrated crop-poultry …

Reproductive Traits And Change In Body Shape Of Neonates In The Oak Forest Skink, Plestiodon Lynxe, Manuel Feria-Ortiz, Uri Omar García-Vázquez, Carlos Joaquín Pavón-Vázquez, Adrián Nieto-Montes De Oca

Publications and Research

Reproductive traits are critically important for understanding how organisms adapt to their respective environments. In this study, we provide information on relative litter mass (RLM) and other litter and neonate related characters of nine female Plestiodon lynxe captured in the field. We also recorded seven body dimensions in 16 neonates and 15 two-month juveniles, and on the basis of these dimensions we compared the body shape of these two age classes to detect changes in the proportions of body parts. The average litter size (4.55) is larger than that found in other viviparous species of Plestiodon, but smaller than …

Immunohistochemical Localization Of Kisspeptin And Its Receptor In The Equine Ovary, Bryce M. Gilbert

LSU Master's Theses

Kisspeptin is recognized for its role as the gatekeeper of reproduction in most mammalian species. However, its role in regulation of reproduction at the ovarian level is poorly understood in the horse. In this study, ovaries from follicular phase, luteal phase, anestrous period, and mares treated with ECP-sulpiride were subjected to immunohistochemistry to characterize kisspeptin-10 (Kp10) and its receptor (Kiss1r) protein expression throughout each reproductive stage and follicle type. Kisspeptin and receptor staining was detected in all follicle types (primordial, preantral, and antral) throughout all reproductive stages, as well as oocytes, corpora lutea, and ovulation fossa. The pattern of Kp10 …

Professional Agricultural Workers Journal

Gastrointestinal (GI) parasites pose a major health concern in goats raised in pastures. The study objective was to evaluate GI parasites’ prevalence in lactating Kiko does and kids stocked in woodlands with supplemental grazing or feedstuffs. Seventeen lactating Kiko does, and their thirty-three kids were divided into two groups. Group 1 was supplemented with grazing in silvopastures and Group 2 with ad libitum hay and corn (0.5% of metabolic weight) along with stocking in woodland plots rotationally. Fecal samples were analyzed for type and quantity of GI parasites from animals having FAMACHA score 3 and higher. Group-1 does showed a …

Establishing A Small-Scale Pastured Poultry Operation In Kentucky, Frederick N. Bebe

Professional Agricultural Workers Journal

Pastured poultry is poultry rotationally raised on pasture, as opposed to large-scale confinement operations. There has been a growing demand for pastured poultry as a result of the adverse effects of the use of antibiotics in large-scale caged systems and pastured poultry’s attributable nutritional and economic benefits to consumers. As a result, an increasing number of small-scale farmers in Kentucky have begun raising birds both for personal consumption and for supplemental income, in conjunction with other farm enterprises. Poultry is the number one agricultural commodity in Kentucky. Thus, knowledge of how to establish small-scale pastured poultry operations as an alternate …

The 3p Framework: A Comprehensive Approach To Coping With The Emerging Infectious Disease Crisis, Orsolya Molnár, Eric Hoberg, Valeria Trivellone, Gábor Földvári, Daniel R. Brooks

MANTER: Journal of Parasite Biodiversity

The COVID-19 pandemic is the latest example of the profound socioeconomic impact of the emerging infectious disease (EID) crisis. Current health security measures are based on a failed evolutionary paradigm that presumes EID is rare and cannot be predicted because emergence requires the prior evolution of novel genetic capacities for colonizing a new host. Consequently, crisis response through preparation for previously emerged diseases and palliation following outbreaks have been the only health security options, which have become unsustainably expensive and unsuccessful. The Stockholm paradigm (SP) is an alternative evolutionary framework that suggests host changes are the result of changing conditions …
