The Cost Of Affordable Food, Candice L. Cobuzzi

SURGE

When someone puts a piece of food in front of me, I don’t just see a piece of food.

Instead, I see an innocent cow being cornered by a forklift and slaughtered, its limp, moist tissue hung on a long conveyer belt with hundreds of others.

I see hundreds of chemically-injected chickens packed into a dark barn with no hope of seeing sunlight in their lifetime.

I see immigrants pulled from their houses like criminals, taken away from the lives they’ve spent years building for themselves and their families, working for the same food company that courted them into the …

Transcriptional Regulation Of The Porcine Gnrh Receptor Gene By Glucocorticoids, Chanho Lee

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

Binding of GnRH to its receptor (GnRHR) stimulates the synthesis and secretion of the gonadotropins, as well as up-regulation of GnRHR. Thus, the interaction between GnRH and GnRHR represents a central point for regulation of reproduction. Glucocorticoids alter reproduction by reducing GnRH responsiveness of gonadotropes within the anterior pituitary gland, potentially via transcriptional regulation of the GnRHR gene. Investigation into this mechanism, however, revealed that the murine GnRHR gene was stimulated by glucocorticoids. To determine the effect of glucocorticoids on porcine GnRHR gene expression, gonadotrope-derived αT3-1 cells were transiently transfected with a vector containing 5118 bp of 5’ flanking sequence …

Diseases At The Livestock–Wildlife Interface: Status, Challenges, And Opportunities In The United States, Ryan S. Miller, Mathew L. Farnsworth, Jennifer L. Malmberg

Other Publications in Zoonotics and Wildlife Disease

In the last half century, significant attention has been given to animal diseases; however, our understanding of disease processes and how to manage them at the livestock–wildlife interface remains limited. In this study, we conduct a systematic review of the scientific literature to evaluate the status of diseases at the livestock–wildlife interface in the United States. Specifically, the goals of the literature review were three fold: first to evaluate domestic animal diseases currently found in the United States where wildlife may play a role; second to identify critical issues faced in managing these diseases at the livestock–wildlife interface; and third …

Mycobacterium Bovis (Bovine Tuberculosis) Infection In North American Wildlife: Current Status And Opportunities For Mitigation Of Risks Of Further Infection In Wildlife Populations, Ryan S. Miller, Steven J. Sweeney

Other Publications in Zoonotics and Wildlife Disease

Mycobacterium bovis (M. bovis), the causative agent of bovine tuberculosis, has been identified in nine geographically distinct wildlife populations in North America and Hawaii and is endemic in at least three populations, including members of the Bovidae, Cervidae, and Suidae families. The emergence of M. bovis in North American wildlife poses a serious and growing risk for livestock and human health and for the recreational hunting industry. Experience in many countries, including the USA and Canada, has shown that while M. bovis can be controlled when restricted to livestock species, it is almost impossible to eradicate …

Implementation Of Aquaponics In Education: An Assessment Of Challenges, Solutions And Success, Emily Rose Hart

Masters Theses 1911 - February 2014

Aquaponics is the combination of aquaculture and hydroponic technology to grow both fish and plants together in a closed-loop system. While aquaponics can play a role in increasing food security, it may also be a potential educational tool because of its interdisciplinary nature and required technological skill set. With aquaponics, students could conduct hands-on activities involving chemistry, physics and biology to solidify their understanding of a range of theories. Beyond standard science, technology, engineering and mathematics (STEM) principles, aquaponics may be related to projects on sustainability, environmental science, agriculture, the food system, health, economics, business and marketing. The interdisciplinary nature …

The Breeding and Genetics Symposium titled “Systems Biology in Animal Breeding: Identifying relationships among markers, genes, and phenotypes” was held at the Joint Annual Meeting of the American Society of Animal Science and the American Dairy Science Association in Phoenix, Arizona, July 15-19, 2012. The primary goal of the symposium was to demonstrate the use of high-density SNP genotypes to determine the complex regulatory relationships among genotypes and phenotypes but also to present methods for studying complex relationships among phenotypes. Case studies from mammalian and avian species were included to emphasize the broad applicability of these methods.

Index Selection In Terminal Sires Improves Lamb Performance At Finishing, G. C. Márquez, W. Haresign, M. H. Davies, Rainer Roehe, L. Bünger, G. Simm, Ronald M. Lewis

Department of Animal Science: Faculty Publications

Lamb meat is often perceived by consumers as fatty, and consumption has decreased in recent decades. A lean growth index was developed in the UK for terminal sire breeds to increase carcass lean content and constrain fat content at a constant age end point. The purposes of this study were 1) to evaluate the effects of index selection of terminal sires on their crossbred offspring at finishing and 2) to evaluate its effectiveness within terminal sire breeds. Approximately 70% of lambs marketed in the UK have been sired by rams of breeds typically thought of as specialized terminal sires. The …

Effects Of Forage Species Or Concentrate Finishing On Animal Performance, Carcass And Meat Quality, S. K. Duckett, J. P.S. Neel, Ronald M. Lewis, J. P. Fontenot, W M. Clapham

Department of Animal Science: Faculty Publications

Angus-cross steers (n = 128; initial BW = 270 ± 3.8 kg) were used in a 3-yr study to assess effects of forage species grazed before slaughter versus concentrate finishing on carcass and meat quality. At the completion of the stockering phase, steers were randomly allotted to mixed pasture (MP; n = 36/yr) or corn-silage concentrate (CON; n = 12/yr) finishing treatments. At 40 d before harvest, MP steers were randomly divided into 3 forage species treatments: alfalfa (AL), pearl millet (PM), or mixed pasture (MP). Average daily BW gain was greater (P = 0.001) for CON than …

Evaluation Of Electrostatic Particle Ionization And Biocurtain™ Technologies To Reduce Air Pollutants From Broiler Houses, Sheryll B. Jerez, W Faulkner, K. D. Casey, M S. Borhan, R. A. Smith

Faculty Publications

The continuing growth of poultry production, along with the increasing urbanization of rural areas, is leading to more odor-related complaints from neighboring communities and more scrutiny from policy makers. It is, therefore, in the best interest of poultry producers to look at control methods for abating odors. Previous studies have shown that substantial amounts of volatile and odorous compounds are adsorbed and transported by dust particles. Thus, by reducing the amount of dust emitted from poultry facilities such as broiler houses, odor may be reduced as well. The objective of this study was to evaluate the effectiveness of two commercially …

The Influence Of Different Cover Types On American Robin Nest Success In Organic Agroecosystems, John E. Quinn, Amy Oden, James R. Brandle

Biology Publications

There are many opportunities for biodiversity conservation in organic farm systems. Successful and sustainable conservation efforts in organic systems, however, need to measure appropriate outcomes. In particular, data are needed on the breeding success of associated wildlife species. We measured nesting success of the American Robin (Turdus migratorius) in woodlands embedded within eight organic farms in eastern Nebraska. We modeled daily nest survival rate to identify land use and land cover patterns that optimize conservation of birds in organic farm systems. The percentage of a crop in the fields adjacent to linear woodlands best predicted daily survival rate. …

Live Weight Parameters In Dorper, Damara And Australian Merino Lambs Subjected To Restricted Feeding, Tim Scanlon, Andre M. Almeida, Andrew Van Burgel, Tanya Kilminster, John Milton, Johan C. Greeff, Chris Oldham

Journal articles

Seasonal weight loss (SWL) is a serious constraint to ruminant production in tropical and Mediterranean climates. SWL is controlled using supplementation, costly and difficult to implement in extensive production systems; or alternatively, using breeds with a natural adaptation to tropical climates, namely hair and fat tailed sheep. Albeit a 15-year presence in Australia, little is known on how Dorper and Damara sheep compared to the most widely used sheep breed in Australia, the Australian Merino. In this trial, the responses of the Damara, Dorper and Merino breeds to nutritional stress were compared during a 42-day trial. Seventy-two ram lambs, 24 …

The Buzz On Bees, Rebecca Ruiz

Lewis Honors College Capstone Collection

Apis mellifera, more commonly known as the honeybee, plays a pivotal role in the ecosystem and in the survival of the planet. Many do not understand, nor realize, that the honeybee offers a wide array of products and services besides sweet honey. Honeybees have become endangered at a time when their presence is vital and evidence indicates that they can be the means to a more sustainable future for our planet. Particularly focused on in this research are the ideas of honeybees’ essential presence in medical advances, their participation in global economics, and their involvement in the development of …

Benefits And Costs Of Saltland Pastures On Moderately Salt-Affected Land, Justin Hardy, Arjen Ryder

Resource management technical reports

Summary The analyses in this report show that there could be significant economic benefits to the state, regions and affected farm businesses from establishing improved saltland pasture systems on moderately salt-affected land. The report clearly describes the methods of analysis and the assumptions about prices, productivity and adoption levels. The price of grain has been used as the key factor controlling the economic value of the saltland grazing because grain is the alternative supplementary feed for sheep over the summer and autumn period. Therefore, where yield is below break-even on moderately salt-affected land, it has a higher economic value and …

Brucellosis is the one of most common livestock zoonoses in Georgia, resulting in significant economic losses. Livestock were sampled in three regions of Georgia (Kakheti, Kvemo Kartli, Imereti). Districts that historically reported high numbers of brucellosis related morbidity were selected for serological, bacteriological and molecular surveys. Surveying efforts yielded samples from 10,819 large and small ruminants. In total, 735 serological tests were positive on Rose Bengal and 33 bacterial isolates were recovered and identified as Brucella melitensis or Brucella abortus by microbiology and AMOS-PCR. A Bayesian framework was implemented to estimate the true prevalence of the disease given an imperfect …
