Evaluation Of Selected Bacillus Direct-Fed Microbial Candidates In Reduced Energy Diets On Live Performance, Carcass Characteristics, And Foot Pad Dermatitis, Kyle Teague
Graduate Theses and Dissertations
Bacillus spp. are ubiquitous, Gram-positive, spore forming bacteria that are commonly recovered from the environment and gastrointestinal tract (GIT) of poultry. These spores are capable of withstanding harsh condition such as feed pelletization, which facilitates inclusion in poultry feeds. Once ingested by the bird, spores germinate into metabolically active vegetative cells which can produce extracellular enzymes which can hydrolyze otherwise indigestible components of the feed. Soybean meal (SBM) is the gold standard vegetable protein source for non-ruminant animals worldwide and is included in practically all poultry diets in the United States at levels ranging from 10 to more than 30%. …
Distillers Dried Grains With Solubles: Determination Of Metabolizable Energy Values Using Regression-Based Assays And Their Correlation With Chemical Composition, Kenia Mitre
Graduate Theses and Dissertations
The inherent variability and lack of standardization of in vivo assays to determine the metabolizable energy (ME) of DDGS has led to inconsistent values and limited its potential to use in broiler diets. Therefore, two experiments were conducted to characterize the content of nitrogen-corrected ME (MEn) in 11 DDGS sources obtained from various ethanol plants using a regression-based broiler assay and to attempt to develop equations to predict MEn based on its chemical composition. In experiment 1, the objectives were to determine the influence of inclusion level and feed intake on the resulting ME and MEn values of a single …
Efficacy Of Natural Compounds With Novel Carrier Systems For Controlling Campylobacter Jejuni In Post-Harvest Poultry, Sandip Shrestha
Efficacy Of Natural Compounds With Novel Carrier Systems For Controlling Campylobacter Jejuni In Post-Harvest Poultry, Sandip Shrestha
Graduate Theses and Dissertations
Campylobacter jejuni, a leading cause of bacterial gastroenteritis worldwide, is strongly associated with the consumption and/or mishandling of raw contaminated poultry products. Thus, interventions aiming to reduce C. jejuni counts on poultry products could greatly reduce the incidence of human campylobacteriosis. In the first study, the efficacy of a generally recongnized as safe (GRAS) compound, carvacrol (CR; derived from oregano oil), as an antimicrobial wash treatment to reduce C. jejuni on chicken skin was evaluated. Three delivery systems of CR: suspension, emulsion and nanoemulsion were used. C. jejuni counts were reduced up to 4 log10 cfu/sample by 2% dose of …
Field Day : Poultry Research : A Progress Report : Poultry Research Station, Wembley, Department Of Agriculture, Western Australia
Field Day : Poultry Research : A Progress Report : Poultry Research Station, Wembley, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
AT the fourth field day held at the Department of Agriculture's Poultry Research Station at Wembley recently, about 150 visitors, most of them commercial poultry farmers, inspected the station and saw the progress of the comprehensive research programme being carried out by officers of the Department's Poultry Branch.
Better Rations For Broiler Production, P Smetana
Better Rations For Broiler Production, P Smetana
Journal of the Department of Agriculture, Western Australia, Series 4
DURING 1959, trials were conducted at the Poultry Research Station, Herdsman Lake, with the object of developing a broiler-feeding ration that was better than the one at present recommended by the Department of Agriculture and commonly used by local broiler producers.
