Swine can be infected with many different mycoplasmas. Some are
important pathogens, causing significant health and welfare issues
in pigs and major losses to the swine industry worldwide. Other
mycoplasmas are not pathogenic for swine and can be considered
commensals. This book provides up-to-date scientific, clinical and
practical information of the most important pathogenic mycoplasmas
in swine. Most emphasis has been placed on Mycoplasma hyopneumoniae
as the most economically important, but other pathogenic species
like Mycoplasma hyorhinis, Mycoplasma hyosynoviae and Mycoplasma
suis are also discussed. Written by internationally renowned
scientists and clinicians from all over the world, this book draws
together in depth knowledge, expertise and experience in swine
mycoplasmas to provide an evidence-based, academically rigorous and
practical collection. It aims to serve the scientific and
veterinary community and the swine industry worldwide.
This collection features five peer-reviewed reviews on improving
biosecurity in livestock production. The first chapter highlights
the importance of implementing biosecurity measures along the pig
production chain as a means of minimising disease introduction
(external biosecurity) and spread (internal biosecurity) throughout
the farm. The second chapter reviews the diagnosis and monitoring
of common pig diseases, as well as the control measures that can be
implemented on the farm, focussing on the importance of
establishing effective biosecurity measures. The third chapter
provides a brief overview of the emergence and re-emergence of
several infectious pathogens of poultry. The chapter highlights the
integral role of improving biosecurity in poultry flocks as a means
of mitigating future disease risk, including proper cleaning and
disinfection techniques. The fourth chapter provides an overview of
good farming practices for beef cattle farms, with particular
discussion of biosecurity, animal welfare and the importance of
clean cattle policies. The final chapter summarises key issues of
biosecurity which arise in organic animal farming and discusses
their significance to human health. Two case studies are presented
to demonstrate the successful implementation of biosecurity plans
as a means of reducing disease risk.
Whilst it can mean enhanced biosecurity, intensive and globalised
pig production (based on a narrowing genetic base) also potentially
increases the risk of disease and its spread. It has been estimated
that diseases can lower pig production efficiency by 10-15%, though
financial losses can be much greater. Optimising pig herd health
and production highlights the need to develop more preventative
measures that can be implemented to tackle the increasing threat of
disease. The book addresses recent developments in disease
prevention, focussing on how farmers and producers can utilise feed
management and housing to optimise pig health, as well as the role
of vaccine development in preventing the onset of endemic and
emerging diseases in pigs. Through highlighting the importance of
understanding and identifying disease, the book showcases how our
understanding of the mechanisms of transmission for some of the key
porcine viral and bacterial diseases can be applied to optimise pig
herd health and production.
This collection features four peer-reviewed literature reviews on
bacterial diseases affecting pigs. The first chapter summarises
recent research on the causes and epidemiology of major bacteria,
viruses and parasites found in pig production, focussing on those
with a particular impact on safety and global production, such as
Escherichia coli (E. coli), Salmonella typhimurium and African
swine fever virus. The second chapter discusses classical
phenotypic characteristics and more advanced molecular techniques
to identify and classify bacterial pathogens affecting swine health
and performance. The chapter explores the different modes of
transmission, as well as the commonly used measures for prevention
and control, including vaccinations. The third chapter reviews the
development of dysbiosis and post-weaning diarrhoea (PWD) in
piglets and the consequent economic losses these diseases cause for
the global pig industry. The chapter considers the role of animal
nutrition and dietary strategies to optimise gut function as a
means of preventing dysbiosis and PWD. The final chapter assesses
methods of improving gut function in pigs to optimise health and
prevent pathogen colonization. The chapter discusses research on
genes associated with pathogen resistance and porcine immune
response and reviews the role of dietary and nutritional strategies
in preventing intestinal pathogen colonisation.
'...individual chapters provide very thorough, up-to-date reviews
of health and welfare of pigs during different stages of
production...The health section does a good job of summarizing the
current major disease challenges facing pig production...If you
want up-to-date reviews on some of the most pressing welfare issues
in different stages of production, there are some good chapters
included.' Animal Welfare Pig meat is the most widely-consumed meat
in the world. Previous growth in production has relied, in part, on
more intensive systems. In meeting rising demand, these systems
face challenges such as the ongoing threat of zoonotic diseases,
the need to improve feed efficiency in the face of rising costs,
the need to reduce the environmental impact of pig production and
increasing concerns about animal welfare. This volume looks at
animal health and welfare. Part 1 reviews the main diseases
affecting pigs as well as ways of managing diseases and boosting
pig immune function. Part 2 reviews what we know about pig
behaviour and appropriate welfare standards. It also assesses the
welfare of different groups of pigs, from gilts and sows to weaned
piglets and finishing pigs, as well as transport, lairage and
slaughter. With its distinguished editor and international team of
expert authors, this will be a standard reference for researchers
in swine science, producers, government and other organisations
involved in supporting pig production. It is accompanied by two
companion volumes which focus on safety, quality and sustainability
as well as animal breeding and nutrition.
