This collection features five peer-reviewed reviews on dietary
supplements in dairy cattle nutrition. The first chapter addresses
the manipulation of rumen fermentation to maximise the efficiency
of feed utilisation and increase ruminant productivity. It
considers a wide variety of approaches, including the use of
dietary buffers. The second chapter reviews the use of probiotics
as supplements for ruminants to promote digestive efficiency and
productivity. The chapter summarises the benefits and modes of
action of probiotics, as well as their role in optimising feed
efficiency and reducing methane production. The third chapter
considers the beneficial roles of plant secondary compounds in
sustainable ruminant nutrition. It describes the effects and
composition of the three major groups of plant secondary compounds:
essential oils, tannins and saponins. The fourth chapter discusses
the growing need for alternative feed sources as a result of
increasing demand for meat and dairy products. The chapter reviews
the nutritional composition of seaweed and introduces it as a
potential novel protein supplement in animal feeds. The final
chapter evaluates the role of macroalgae as a potential
anti-methanogenic ruminant feed resource and reviews its impact on
animal production and performance.
"...this book covers a range of algal phyla, specialised algal
bioprocessing and application topics that make it very interesting
for a broad audience. Each chapter covers a theme in such a way
that can easily be read by a non-specialist but, as the authors
incorporate recent published papers, the book will also be
interesting for experts...I also recommend the book for
entrepreneurs and technical staff working in different algal-based
operations." (Journal of Phycology) As the global demand for meat
increases due to population and economic growth, more pressure has
been placed on the animal feed sector to support sustainable
livestock production, whilst also ensuring the nutritional value
and palatability of feed. With traditional sources of protein,
including oilseeds and distiller grains, considered as major
contributors to climate change, there is growing interest in
establishing alternative, more 'climate-smart' sources of protein,
such as seaweed and other forms of microalgae that can supplement
livestock diets. Seaweed and microalgae as alternative sources of
protein summarises current advances in utilising macroalgae and
microalgae as alternative sources of proteins. The collection
reviews processes of protein formation in macroalgae and
microalgae, macroalgae farming and processing as well as microalgae
bioprocessing. Chapters also discuss the practical application of
seaweed as an alternative protein source in ruminant, pig, poultry
and fish diets. Edited by Professor Xin Gen Lei, Cornell
University, USA, Seaweed and microalgae as alternative sources of
protein will be a standard reference for researchers from
universities or other research centres involved in
macroalgae/microalgae production and livestock nutrition, companies
involved in the manufacture or supply of animal feed or livestock
nutrition services, government and other agencies regulating the
animal feed sector, as well as farmers interested in furthering
their knowledge on recent developments in the animal feed/livestock
nutrition sector.
