Amini, Sina (2013-03-26)Near-membrane and trans-membrane proteins and their interactions with the extracellular matrix (ECM) can yield valuable information about cell dynamics. However, advances in the field of nanoscale cellular processes have ...
-
Oubre, Cherie Morgan (Texas A&M University, 2006-08-16)The aim of this study was to identify common messenger molecules used in both the immune and the neuroendocrine systems in birds, and to shed light on a cell type within the bursa of Fabricius that has historically been ...
-
Shen, Shixue (2009-06-02)Tremendous improvements have been achieved in growth rates and feed efficiency in commercial broiler birds. However, fast growth broilers generally show weak immune competence and disease resistance. Innate immunity is the ...
-
Krawczel, Peter Downs (Texas A&M University, 2007-04-25)Recommendations for the transportation of lambs from a European Commission, which required rest stops of 6 or 24 h, every 8 h, were evaluated for efficacy of reducing stress indicators using Rambouillet x Suffolk lambs ...
-
Barri, Adriana (Texas A&M University, 2005-02-17)The objective of this investigation was to evaluate the effects of administering CpG-ODN to commercial strain chickens as a potential adjuvant to vaccination against Salmonella, Eimeria spp., and Newcastle disease virus, ...
-
Ameiss, Keith Allen (Texas A&M University, 2005-08-29)The purpose of this research was to investigate selected methods of mucosal immunization for commercial chickens. Induction of mucosal immunity in commercial chickens through the use of orally administered subunit vaccines ...
-
Gutierrez, Omar (2010-01-14)A series of four experiments were conducted to evaluate whether a preconditioning period, in which adult leghorn cockerels are allowed 3 weeks to adapt to diets containing relatively high levels of guar meal (GM) resulted ...
-
Iselt, Stephanie Mae (2013-04-08)The principal objective of this investigation was to evaluate the effects of mycotoxin contaminated diets (deoxynivalenol (DON)), aflatoxin B1 (AFB1), and fumonisin (FUM)), with or without the use of a commercially available ...
-
Klein, Anthony (2010-10-12)The principal objective of this investigation was to evaluate coccidiosis vaccination, with or without probiotic administration, for effects on broiler performance and clinical indices of infection due to field strain ...
-
Horrocks, Sadie Lyn (2012-02-14)Coccidiosis has a negative economic impact on the commercial poultry industry, and probiotics are beneficial bacteria that aid in maintaining healthy gut microflora. We hypothesized that probiotic administration would ...
-
Pohl, Samantha Kaye (2012-02-14)Two experiments were performed to evaluate effects of amprolium administration at specific times and concentrations in replacement broiler breeders of three genetic lines vaccinated against coccidiosis. Effects on performance ...
-
Larrison, Eryn Linnae (2010-07-14)Research has shown that Salmonella can be prevalent in poultry litter, which can be a source of contamination for newly arrived chicks at the poultry house. Since this organism is a pathogen of concern to the poultry ...
-
Bray, Joey Lynn (2009-05-15)Three experiments were conducted to evaluate the impacts of removing antibiotic growth promoters (AGP) on broiler performance and yield and to evaluate alternative products as potential replacements. In experiment one, ...
-
Lee, Jason Thomas (Texas A&M University, 2007-04-25)This research program included a series of experiments to investigate the effect of starter diet protein level on the performance of broilers vaccinated with Coccivac®-B and subsequently challenged with a mixed species ...
-
Stevens, Scott Michael (Texas A&M University, 2005-08-29)One objective of the present investigation was to compare Salmonella and Campylobacter recovery incidence from commercially processed turkeys immediately prior to and following pre-chill and immersion chiller intervention ...
-
Dunkley, Kingsley Delroy (2009-05-15)In these studies we evaluated specific environmental stimuli relevant to Salmonella virulence and physiology in the gastrointestinal tract of chickens. Results from Salmonella growth in steady state, glucose-limiting ...
-
Hernandez, Charles Andrew (2012-02-14)Campylobacter jejuni is a commensal microorganism of the poultry gastrointestinal tract. Broilers, layers, ducks, turkeys, and quails can be colonized by Campylobacter without illness occurring. The vast majority of human ...
-
Abi Ghanem, Daad Ali (2009-06-02)An antibody library against Eimeria tenella sporozoites was constructed by phage display. Total RNA was isolated from the spleen, bone marrow, and ceca of immune chickens, and was used to reverse-transcribe cDNA. Heavy and ...
-
Waneck, Casey R. (2011-08-08)Gangrenous dermatitis (GD) has become a major health problem among broiler flocks in the United States, resulting in high mortality, carcass condemnations, and trimmed parts. There are large economic losses due to GD. ...
-
Coufal, Craig Daniel (Texas A&M University, 2005-11-01)The environmental impacts of broiler production have recently gained considerable public attention due to concerns regarding the amount of ammonia (NH3) released into the atmosphere from poultry facilities. Sound scientific ...
