Reduction Of Campylobacter Jejuni On Chicken Wingettes By Treatment With Caprylic Acid, Chitosan Or Protective Cultures Of Lactobacillus Spp., Ann Nicole Woo-Ming
Graduate Theses and Dissertations
Poultry is one of the main sources of protein in the United States and in 2014 Americans ate approximately 100 lbs per person. However, consumption of poultry products is strongly associated with foodborne illness from Campylobacter. In the first study, chitosan, caprylic acid and their combination were evaluated as a coating treatment for the reduction of Campylobacter jejuni on poultry products. For the initial screening trials, chitosan of three different molecular weights (15-50 kDa, 190-310 kDa and 400-600 kDa) was evaluated at three concentrations (0.5%, 1.0%, 2.0%) and separately, caprylic acid was tested at 0.5%, 1.0% and 2.0% using chicken …

Poultry health has been traditionally maintained by hygenic measures, vaccinations, and the use of antibiotics. Modern husbandry management considers the use of probiotics as a natural way to protect birds against many everyday pathogens. Different strains of Bacillus spp. have proved to have beneficial effects in poultry production. However, the most used bacterium in commercial probiotics is Lactobacillus, a vegetative cell. In contrast, Bacillus spp are bacterial spores, highly resistant to harsh conditions, which makes them preferable, in some cases, to Lactobacillus because of shelf life and storage conditions. There is published information regarding mycotoxin detoxification by bacteria. Mycotoxins are …

Abstract Background Magnetic resonance imaging is a noninvasive method of evaluating embryonic development. Diffusion tensor imaging (DTI), based on the directional diffusivity of water molecules, is an established method of evaluating tissue structure. Yet embryonic motion degrades the in vivo acquisition of long-duration DTI. We used a dual-cooling technique to avoid motion artifact and aimed to investigate whether DTI can be used to monitor chick embryonic skeletal muscle development in ovo, and to investigate the correlation between quantitative DTI parameters fractional anisotropy (FA) and fiber length and quantitative histologic parameters fiber area percentage (FiberArea%) and limb length. Results From 84 …

The human head louse is a cosmopolitan ectoparasite and frequently infests many people, particularly school-age children. Due to widespread pyrethroid resistance and the lack of efficient resistance management, there has been a considerable interest in the protection of uninfested people and prevention of reinfestation by disrupting lice transfer. In this study, two nonclinical model systems (in vitro and in vivo) were used to determine the efficacy of the infestation deterrents, Elimax lotion and Elimax shampoo, against human head lice or poultry chewing lice, respectively. With in vitro assessments, female head lice exhibited significantly higher avoidance responses to hair tufts treated …
A Critical Review Of Electrical Water-Bath Stun Systems For Poultry Slaughter And Recent Developments In Alternative Technologies, Sara J. Shields, A. B. M. Raj
A Critical Review Of Electrical Water-Bath Stun Systems For Poultry Slaughter And Recent Developments In Alternative Technologies, Sara J. Shields, A. B. M. Raj
Sara Shields, PhD
Prior to slaughter, most farmed birds move through a constant-voltage, multiple- bird, electrical water-bath stun system. Using this system subjects live birds to stressful and painful shackling, and the potential exists for them to receive prestun electric shocks and induction of seizures while still conscious. The existing elec- trical water-bath stunner settings, particularly those used in U.S. slaughter plants, are not necessarily based on sound scientific data that they produce a consistent, immediate stun, and research indicates that they are not effective in all birds. Further, in multiple-bird, electrical water-bath systems, birds may miss the stunner completely. Evidence suggests that …
Intestinal Inflammation Model Inducing Gut Leakage By Different Methods In Broiler Chickens Using Fitc-D As A Marker, Eduardo Vicuna
Intestinal Inflammation Model Inducing Gut Leakage By Different Methods In Broiler Chickens Using Fitc-D As A Marker, Eduardo Vicuna
Graduate Theses and Dissertations
Traditionally, antibiotic growth promoters (AGP) have been used in food animals to reduce enteric inflammation and maintain intestinal homeostasis, thus improving performance. Due to increasing restrictions regarding the use of AGP, precise and high throughput enteric inflammation models and markers to search for effective alternatives are urgently needed. Oral administration of fluorescein isothiocyanate dextran (FITC-d) and its passage into blood can be used as a marker for tight junction permeability. FITC-d is a large molecule (3-5 kDa) which does not usually leak through the intact gastrointestinal tract barrier. However, when conditions disrupt the tight junctions between epithelial cells, the FITC-d …
Ectoparasitism Shortens The Breeding Season In A Colonial Bird, Charles R. Brown, Mary Bomberger Brown
Ectoparasitism Shortens The Breeding Season In A Colonial Bird, Charles R. Brown, Mary Bomberger Brown

When blood-feeding parasites increase seasonally, their deleterious effects may prevent some host species, especially those living in large groups where parasites are numerous, from reproducing later in the summer. Yet the role of parasites in regulating the length of a host’s breeding season—and thus the host’s opportunity for multiple brooding—has not been systematically investigated. The highly colonial cliff swallow (Petrochelidon pyrrhonota), a temperate-latitude migratory songbird in the western Great Plains, USA, typically has a relatively short (eight to nine week) breeding season, with birds rarely nesting late in the summer. Colonies at which ectoparasitic swallow bugs (Oeciacus vicarius) were experimentally …

Efficacy Of Beta-Resorcylic Acid To Reduce Campylobacter Jejuni In Pre-Harvest And Post-Harvest Poultry, Basanta Raj Wagle
Efficacy Of Beta-Resorcylic Acid To Reduce Campylobacter Jejuni In Pre-Harvest And Post-Harvest Poultry, Basanta Raj Wagle
Graduate Theses and Dissertations
Campylobacteriosis is one of the leading foodborne illnesses in United States, and is associated with the consumption of poultry and poultry products. Reducing Campylobacter in these species will reduce the burden of this disease. Unfortunately, most strategies employed to reduce Campylobacter in poultry have either not been successful or produced inconsistent results. One potential control strategy is the use of β-resorcylic acid (BR), a phytophenolic compound classified by the US FDA as "Everything Added to Food in the United States" (EAF 3045) and is therefore deemed safe for consumption. This compounds has antibacterial activity against Salmonella, however, its efficacy to …

Maestría en Ciencias Veterinarias
Mundialmente el sector avícola ha sido de gran importancia tanto en su impacto en seguridad alimentaria como en sus aportes para el desarrollo económico. En los últimos 20 años el sector avícola se ha consolidado en una de las producciones más dinámica dentro de Colombia. Sin embargo este desarrollo se puede afectar por la presentación de enfermedades infecciosas, es por esto que se pretende evaluar la actividad de enfermedades virales en explotaciones de ponedoras comerciales de Fómeque Cundinamarca. Se realizó la toma de muestras a la mitad y al final del periodo de cría y levante de las ponedoras, con …
