Evaluation Of Bacillus Spp Candidates For Aflatoxin B1 Biodegradation In Broiler Chickens, Rosario Galarza Seeber
Evaluation Of Bacillus Spp Candidates For Aflatoxin B1 Biodegradation In Broiler Chickens, Rosario Galarza Seeber
Graduate Theses and Dissertations
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 …
Efficacy Of Selected Disinfectants Against Salmonella Isolates From Broiler Breeders, Arslan Aslam
Efficacy Of Selected Disinfectants Against Salmonella Isolates From Broiler Breeders, Arslan Aslam
Graduate Theses and Dissertations
Salmonella have been causing huge losses in the poultry industry and have been a major cause food borne illness for many years. Salmonella infections in humans from poultry have been increasing. Good hygiene and biosecurity measures can reduce the incidence of Salmonella infections at poultry farms. Disinfection is a most important measure taken to prevent Salmonellosis in poultry. This research was conducted to determine the efficacy of 12 disinfectants against seven Salmonella isolates in the presence and absence of organic matter. A bacterial solution of a specific optical density value was prepared and .05x, .1x and .2x concentrations of disinfectants …
Effects Of Respiratory Vaccination Timing And Hormonal Growth Implant On Health, Performance, And Immunity Of Newly Received Stocker Calves, Kimberly Denise Poe
Effects Of Respiratory Vaccination Timing And Hormonal Growth Implant On Health, Performance, And Immunity Of Newly Received Stocker Calves, Kimberly Denise Poe
Graduate Theses and Dissertations
Stress alters the immune system and vaccination during this time may reduce vaccine response; whereas, growth implants may shift metabolism to enhance tissue deposition in exchange for energy required for immune response during bovine respiratory disease (BRD) challenge. This study was conducted to determine the effects of pentavalent respiratory vaccination timing with or without a hormonal growth implant on arrival (d 0) on health, performance, complete blood count, and vaccine response in high&ndashrisk, newly received stocker calves during a 42&ndashd receiving period. Crossbred bull and steer calves (n = 385) were weighed (initial BW = 202 ± 4.1 kg), stratified …
