This collection features four peer-reviewed literature reviews on
bone health in poultry. The first chapter reviews the literature on
genetic mapping of skeletal traits in both broilers and layers,
including both the genetics of skeletal defects and bone quality.
As the chapter shows, linkage mapping and genome-wide association
studies have identified promising candidate genes with potential
for breeding more robust birds. The second chapter focuses on
bacterial chondronecrosis with osteomyelitis (BCO), one of the most
common causes of lameness in broilers. The chapter summarizes the
pathogenesis of BCO and reviews the efficacy of probiotics as a
prophylactic treatment. The third chapter discusses bone health in
laying hens. It reviews bone development, keel and other bone
health problems and factors contributing to poor bone health. It
also summarises key strategies for improving bone health, including
breeding, nutrition, rearing practices and housing. The final
chapter assesses the problem of lameness in intensively-reared
broiler flocks. The chapter also discusses skin health in broilers.
It summarises key risk factors as well as ways of monitoring and
reducing the problem, from breeding programmes and enrichment to
sequential feeding regimes.
Providing an exhaustive background on the history of genetically
modified organism (GMO) crops and foods as well as the
controversies surrounding these products, this book allows readers
to develop their own particular viewpoint on the production and use
of GMO substances. Genetic engineering has long been used to impart
desirable characteristics to food plants in order to improve crop
yield, pest resistance, and herbicide tolerance. Genetic
modification of foods, however, has created a storm of controversy
everywhere in the world-including the United States. What are the
benefits of and risks involved with genetically modified organisms
(GMO) and crops? What powerful industry pressures have extended the
sale and use of GMO foods and crops globally? And how should
consumer food products that involve GM ingredients be labeled? GMO
Food: A Reference Handbook addresses these questions and the
complex issues involved, allowing readers to fully understand why
genetically modified organisms represent one of the most important
issues in the 21st century. The book provides clear, factual
information and background on the history of genetically modified
crops and foods, covering topics such as the historic methods of
plant and animal modification (such as cross-breeding) and
important discoveries in genetics, biochemistry, molecular biology,
genetic engineering, and related fields; the social, political,
philosophical, and economic issues that have arisen with these
scientific advances; and the laws and regulations that have
resulted from the range of attitudes about GMO foods. The book also
supplies additional resources for readers performing extensive
research in an annotated bibliography of books, articles, reports,
and web pages. Presents both historical and current views of the
topic that provide readers with a neutral presentation of the hard
science as well as the social issues in question Includes
perspective essays written by individuals with expertise in issues
related to the production and distribution of GMO foods in the
United States and other parts of the world Assesses the
long-existing differences in attitudes toward the development and
commercialization of GMO foods and crops in the United States
versus in the European Union Addresses the ongoing debate regarding
whether and how genetically modified products should be labeled for
sale
The Bambara groundnut (BGN) or Vigna subterranea is an extremely
hardy grain legume. As it produces reasonable yields even under
conditions of drought and low soil fertility, it is also a
climate-smart crop. Previously underutilized, BGN is the subject of
growing interest among researchers and consumers for its balanced
nutritional profile. Indigenous consumers of BGN report medicinal
benefits from the plant; however, such knowledge is at risk of
being lost with the urbanization and changing lifestyles of younger
generations. To date, there is no comprehensive resource on the
Bambara groundnut, despite market demand for plant proteins around
the globe. Authored by scientists who have researched and developed
patents using BGN, Bambara Groundnut: Utilization and Future
Prospects aims to fill this gap. The text provides in-depth
coverage on breeding, food and feed utilization, medicinal benefits
and future research prospects. Drawing on both indigenous knowledge
and cutting-edge research, Bambara Groundnut is the first book to
fully explore the potential of this remarkable crop.
Abiotic and biotic stress factors, including drought, salinity,
waterlog, temperature extremes, mineral nutrients, heavy metals,
plant diseases, nematodes, viruses, and diseases, adversely affect
growth as well as yield of crop plants worldwide. Plant
growth-promoting microorganisms (PGPM) are receiving increasing
attention from agronomists and environmentalists as candidates to
develop an effective, eco-friendly, and sustainable alternative to
conventional agricultural (e.g., chemical fertilizers and
pesticide) and remediation (e.g., chelators-enhanced
phytoremediation) methods employed to deal with climate
change-induced stresses. Recent studies have shown that plant
growth-promoting bacteria (PGPB), rhizobia, arbuscular mycorrhizal
fungi (AMF), cyanobacteria have great potentials in the management
of various agricultural and environmental problems. This book
provides current research of biofertilizers and the role of
microorganisms in plant health, with specific emphasis on the
mitigating strategies to combat plant stresses.
For thousands of years, forest biomass or wood has been among the
main energy sources of humans around the world. Since the
industrial revolution, fossil fuels have replaced wood and become
the dominant source of energy. The use of fossil fuels has the
disadvantage of increasing atmospheric concentrations of greenhouse
gases (GHGs), especially carbon dioxide (CO2), with the consequent
warming of global climate and changes in precipitation. In this
context, the substitution of fossil fuels with renewable energy
sources like forest biomass is among the ways to mitigate climate
change. This book summarizes recent experiences on how to manage
forest land to produce woody biomass for energy use and what are
the potentials to mitigate climate change by substituting fossil
fuels in energy production. In this context, the book addresses how
management can affect the supply of energy biomass using
short-rotation forestry and the conventional forestry applying long
rotations. Furthermore, the book outlines the close interaction
between the ecological systems and industrial systems, which
controls the carbon cycle between the atmosphere and biosphere. In
this context, sustainable forest management is a key to understand
and control indirect carbon emissions due to the utilization of
forest biomass (e.g. from management, harvesting and logistics, and
ecosystem processes), which are often omitted in assessing the
carbon neutrality of energy systems based on forest biomass. The
focus in this book is on forests and forestry in the boreal and
temperate zones, particularly in Northern Europe, where the woody
biomass is widely used in the energy industry for producing energy.
Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), the
spotted wing drosophila (SWD), is the most important pest affecting
berry crop production worldwide. The global fresh fruit trade,
coupled with the ability of the larvae to hide inside the fruit
undetected until after transportation, facilitate their
distribution. SWD is native to Asia, but is increasingly found in
other regions: occurrences have been recorded in the Americas and
Europe, and Africa, and the insects have the potential to adapt and
become established in Oceania. Gathering the experiences of leading
scientists in the management of D. suzukii around the globe, the
book addresses D. suzukii monitoring; biological, chemical and
cultural control; sterile insect technique (SIT); integrated pest
management (IPM), and other control methods. It also discusses the
use of drones, GPS, biotechnology, telemetry and other
technological tools to make the management of this pest more
efficient and accurate. As such, it is a valuable resource for
scientists, professionals and students.
Selenium plays a significant role in preventing certain types of
cancer and cardiovascular diseases. The level of Selenium in the
human body depends on its concentration in food. In turn, the
content in vegetable crops is a function of the soil-plant system.
There are many countries in the world with low Selenium content in
the soil. The average daily human intake is thus limited through
food chain. Analysis of Selenium status suggests that fortification
of the soil substrate with Sodium Selenate, and foliar application
to agricultural crops are both effective means of Selenium
enrichment. Our intention for this publication is to present the
possibilities of augmenting Selenium content by biofortification of
soils and plants through differentiated nutrition. In the first
part of the monograph, the results of Selenium supplementation in
model vegetation experiments are presented. The next part of the
monograph presents the results of foliar supplementation of
Selenium in field conditions. This book is an outstanding reference
source for plant breeders and researchers engaged in
biofortification of horticulture crops. It is also beneficial to
agricultural companies and other stakeholders.
