Optimal gut health is of vital importance to the performance of production animals (fish, poultry, swine, cattle). Gut health is key to making the productivity, well-being and sustainability of animal production more efficient. Directly and indirectly, the environment is a powerful regulator of gastrointestinal physiology that decisively influences the functional state of the animal. Production animals reared under conventional conditions of intensive production are subjected to various exogenous and endogenous sources of environmental factors that can impact gut health. Exogenous factors are environmental stressors derived from external sources connected with diet, infectious disease, mycotoxin exposure, climate (heat and cold), management practices, biosecurity level, housing, litter, feed access, quality, and components. Endogenous factors are host-related such as age, sex, genetics, and breed or are made within the host’s body, such as hormones and neurotransmitters, in response to a stimulus, stressor, or trigger. Endogenous factors serve to communicate signals both locally and distantly in the body. Understanding the interactions between the diverse environmental factors and the different physiological characteristics of the gastrointestinal tract allows us to advance the understanding of gut health and the ability to regulate animal production. The spirit of this book is to critically address how the interactions of different environmental stressors, both internal and external, influence the various functions of the gastrointestinal system of production animals and to be able to use the information to advance scientific research as well as improve the use of the productive tools available.

Selenium (Se) is an essential dietary trace element participating in the regulation of various physiological functions in humans and farm animals through its incorporation into a range of selenoproteins. Low Se content in main feed ingredients is a common problem worldwide and dietary Se supplementation is a current practice in ruminant nutrition. Recent research clearly proved that sodium selenite, used for the last 50 years as a feed supplement, is not an optimal form of Se. However, use of organic selenium in dairy and beef diets can help meet Se requirement and maintain health/high immunocompetence, productive and reproductive performance.

The goal of this book is to provide up-to-date information about the roles of Se in ruminant nutrition and health. A special emphasis is given to the role of selenium as an essential part of the integrated antioxidant system. The concept of using organic Se in ruminant nutrition is described in detail with emphasis on selenomethionine as a storage form of Se in the body. Also, specific Se deficiency-related disorders in ruminants are described and the importance of Se in growth, development, immunity and reproduction is demonstrated. Molecular mechanisms of protective effects of Se under stressful conditions of commercial milk and meat production are characterized.

This book will be of practical importance to dairy and beef producers, to nutritionists and vets as well as for animal scientists, students of agricultural colleges and universities. It will also be of interest for researchers in areas related to environmental sciences, food sciences, physiology, etc.
Do you want to support dairy farmers in adjusting their management regarding the transition period of dairy cows? The book Pathways to health and disease for dairy cows provides veterinarians and farm advisors background information and practical tools. This unique book combines theoretical information with practical tools, and draws crosslinks between six aspects of transition cow biology. The book comprises two parts: an introduction chapter and six study chapters.
The first chapter outlines new ideas about the role of management in dairy farming:
- External conditions, comprising environment and farm management, continuously influence the internal body management of the cow.
- External conditions either support physiology or induce pathophysiology and pathology, for which new definitions are introduced.
- Advisory work on dairy farms must be based on the management of external conditions and not on herd performance data.
The six study chapters focus on the transition period and provide the reader with updated contemporary knowledge on (patho)physiology and pathology, and how they connect with risk factors, preventive measures, and monitoring tools.
Veterinarians and farm advisors must make a professional U-turn to support dairy farmers in solving and preventing disturbances in health and production. This book must be regarded as a start for resetting our traditional view and approach to cow health and disease.
Mosquitoes transmit many of the pathogens that cause zoonotic diseases from wildlife and livestock to people, with devasting consequences for public health. The factors affecting the ecology and evolution of the transmission dynamics of these mosquito-borne pathogens can be revealed using multidisciplinary research approaches. This 7th volume of the ECVD series focuses on the ecological factors that determine the transmission dynamics of mosquito-borne pathogens naturally circulating between animals of different taxa and their importance for human health. The authors revise the current knowledge on the pathogens that affect wildlife, including those maintained in captivity, as well as the use of cutting-edge techniques for the identification of potential vectors of these pathogens. In addition, this volume explores the role of factors related to global change, including changes in landscape use, deforestation and urbanization, as major drivers of the distribution of mosquito vectors and the dynamics of pathogen transmission. Finally, updated information on the approaches used to identify and control mosquito-borne diseases is presented, with a particular focus on those affecting humans. In summary, this book provides an updated review of the different mosquito-borne pathogens affecting animals and their public health relevance.
From basic science to practical applications in human and veterinary medicine and nutrition
For the last 30 years, polyphenols were in the centre of research work worldwide. Silymarin, an extract from a medicinal plant Silybum marianum, also known as milk thistle, has a special place in this group, having been used in human medicine for the management of liver diseases since ancient times. Accumulating scientific evidence indicates that silymarin is characterised by a wide range of protective pharmacological activities and this topic has received tremendous attention in recent years. However, until now there has been no single monograph addressing major questions related to silymarin chemistry, biochemistry and practical applications.
The goal of this book is to provide up to date information about silymarin chemistry, biochemistry and molecular mechanisms of protective actions of this phytochemical with a special emphasis to its vitagene- and transcription factor-modulating properties. Silymarin applications in human diseases, including hepatoprotection, neuroprotection, anti-diabetic, anti-arthritis and other protective activities are reviewed. Immunomodulating, anti-inflammatory, anti-toxic protective activities of silymarin are characterised in detail. Practical applications of silymarin in poultry and animal industry with a special emphasis on its protective roles in gut health maintenance are also presented.
This book will be of practical importance to medical and pharmaceutical scientists, including medical doctors, pharmacists, consultants, etc. as well as to poultry/animal scientists, poultry producers, nutritionists and vets, as well as to students of medical, biological and agricultural backgrounds. It can also be of interest for researchers in areas related to physiology, biochemistry, nutrition and veterinary medicine.

Lessons from 66 years of pitfall trapping
Over the past decades, large amounts of data about carabids have been collected in the Netherlands, initially for the purpose of creating distribution maps for the country. In addition to information from collections and faunistic publications, a significant amount of data came from ecological studies using pitfall traps. Because of the rich tradition of carabidological research in the Netherlands, an exceptionally large database of these pitfall data is available. The database is a mix of approximately 1,500 short-term samples and circa 4,400 so-called 'year-samples', for which pitfalls were functional during the whole activity period of ground beetles in spring and autumn. These year-samples came from 2,850 sites, covering the period of 1953-2018, and represent all habitats on the Dutch landscape. These data offer an unusual view of the presence and activity of this common insect family. The data gathered from pitfall trapping is summarised and provides a fresh integrated perspective about the Dutch ground beetle fauna. The characteristic species composition of 17 habitat groups is described in detail. Over 320 species present in the database have been classified into six main groups, according to their patterns of habitat use. Both the classification of habitats and associated species have been tested and used in various analyses in the book. Two chapters give special attention to changes in the Dutch fauna over the past 66 years by means of extensive trend analysis and relate this understanding to nature conservation. The book provides an extension and update for Turin's (2000) atlas. The Dutch carabid fauna is discussed considering relevant literature but uses predominantly European studies to put the faunal patterns in broader context. This book presents the story of Dutch ground beetles and illustrates the contribution of pitfall trapping to our understanding of the ecology of this fascinating and unusually well-studied group of beetles.
