This book was released on 2003-08-13 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: Johne's Disease is a chronic, progressive intestinal disease caused by infection with Mycobacterium avium subspecies paratuberculosis (Map) that affects primarily ruminant animals. In recent decades there has been growing concern over the lack of effective control of this disease and questions have arisen regarding the possibility that Map infection could be a cause of some cases of Crohn's disease in humans. This report presents a broad outline of the steps that should be taken to control Johne's disease, reduce the spread of Map, and minimize effects of the disease in animals. The report also describes the weaknesses of our current research agenda and provides recommendations for a new research strategy to resolve the question of whether there is a link between Johne's and Crohn's diseases.

This book was released on 2010 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: Paratuberculosis is a worldwide incurable disease of ruminants resulting in a decrease in milk production and slaughter value. The aim of this thesis was to evaluate the epidemiological and economic effectiveness of selected control programmes in infected dairy herds. A stochastic simulation model has been developed to represent both the population dynamics within a dairy herd and the transmission of Mycobacterium avium subsp. paratuberculosis (Map). It has been coupled to an existing bioeconomic model. The spontaneous within-herd progression of Map infection after the introduction of one infected cattle in an initially susceptible herd was studied in the absence of control measure. The effect of within-herd contacts on Map spread in a persistently infected herd was investigated. The cost-effectiveness of test-and-cull strategies to control Map infection in dairy herds was assessed. Simulation outcomes put forward that, even when no control measure is implemented, fadeout can occur if less than two clinically affected animals are present. In persistently infected herds, the two main transmission routes are transmission via the environment of the farm and in utero transmission. Isolating calves from their herd mates during the first weeks of age has no significant impact on Map transmission. Limiting or delaying calf exposure to adult faeces and early culling of clinically affected adults are thus recommended to decrease Map prevalence in infected dairy herds. Systematic test-and-cull appears cost-effective if implemented from the day one infected cattle is introduced. The tool designed here is flexible and enables studying other control options within a dairy herd.

This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: For the MAP-seropositive Canadian dairy herds, the mean loss per 61-cow herd was CD $2,992 (95% C. L, $143--$9741) annually, or CD $49 per cow per year. Herd additional culling losses were responsible for 46% (CD $1374) of the total losses from MAP. Decreased milk production, mortality and reproductive losses accounted for 9% (CD $254), 16% (CD $488) and 29% (CD $875) of the losses, respectively.

Book excerpt: Paratuberculosis, also referred to as Johne's disease, affects principally cattle, goats, sheep, buffalo, deer and other ruminants. It is common worldwide and responsible for significant economic losses in the ruminant livestock industries. A timely follow up to the first book on Paratuberculosis, this new edition is still the only comprehensive text providing both historical context and the latest developments in the field. Examining the epidemiology of paratuberculosis, the organism that causes the disease, and practical aspects of its diagnosis and control, it also addresses the link between paratuberculosis in the food chain and human health implications, including Crohn's disease.

Book excerpt: Johne's disease (paratuberculosis) afflicts cattle worldwide and causes significant economic losses. It is also prevalent in goats and sheep and has been implicated in Johne's disease in humans. The book is divided into six sections covering all aspects of the prevalence, management, diagnosis, control and research on Johne's disease. ]ohne's disease is an international animal health problem, and is of particular importance in the southern States of Australia, especially in the major dairy areas of Victoria where approximately 10% of dairy herds are infected.

Download or read book Bayesian Ideas and Data Analysis written by Ronald Christensen and published by CRC Press. This book was released on 2011-07-07 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: Emphasizing the use of WinBUGS and R to analyze real data, Bayesian Ideas and Data Analysis: An Introduction for Scientists and Statisticians presents statistical tools to address scientific questions. It highlights foundational issues in statistics, the importance of making accurate predictions, and the need for scientists and statisticians to collaborate in analyzing data. The WinBUGS code provided offers a convenient platform to model and analyze a wide range of data. The first five chapters of the book contain core material that spans basic Bayesian ideas, calculations, and inference, including modeling one and two sample data from traditional sampling models. The text then covers Monte Carlo methods, such as Markov chain Monte Carlo (MCMC) simulation. After discussing linear structures in regression, it presents binomial regression, normal regression, analysis of variance, and Poisson regression, before extending these methods to handle correlated data. The authors also examine survival analysis and binary diagnostic testing. A complementary chapter on diagnostic testing for continuous outcomes is available on the book’s website. The last chapter on nonparametric inference explores density estimation and flexible regression modeling of mean functions. The appropriate statistical analysis of data involves a collaborative effort between scientists and statisticians. Exemplifying this approach, Bayesian Ideas and Data Analysis focuses on the necessary tools and concepts for modeling and analyzing scientific data. Data sets and codes are provided on a supplemental website.

This book was released on 2015-03-09 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: From leading ecology advocates, a revealing look at our dependence on cows and a passionate appeal for sustainable living. In Cowed, globally recognized environmentalists Denis and Gail Boyer Hayes offer a revealing analysis of how our beneficial, centuries-old relationship with bovines has evolved into one that now endangers us. Long ago, cows provided food and labor to settlers taming the wild frontier and helped the loggers, ranchers, and farmers who shaped the country’s landscape. Our society is built on the backs of bovines who indelibly stamped our culture, politics, and economics. But our national herd has doubled in size over the past hundred years to 93 million, with devastating consequences for the country’s soil and water. Our love affair with dairy and hamburgers doesn’t help either: eating one pound of beef produces a greater carbon footprint than burning a gallon of gasoline. Denis and Gail Hayes begin their story by tracing the co-evolution of cows and humans, starting with majestic horned aurochs, before taking us through the birth of today’s feedlot farms and the threat of mad cow disease. The authors show how cattle farming today has depleted America’s largest aquifer, created festering lagoons of animal waste, and drastically increased methane production. In their quest to find fresh solutions to our bovine problem, the authors take us to farms across the country from Vermont to Washington. They visit worm ranchers who compost cow waste, learn that feeding cows oregano yields surprising benefits, talk to sustainable farmers who care for their cows while contributing to their communities, and point toward a future in which we eat less, but better, beef. In a deeply researched, engagingly personal narrative, Denis and Gail Hayes provide a glimpse into what we can do now to provide a better future for cows, humans, and the world we inhabit. They show how our relationship with cows is part of the story of America itself.
