Abstract

In the context of disease pathogenesis, it has been observed that after inadequate administration of antibiotics, animals become more susceptible to intestinal colonization and organ invasion by enteropathogens, these could be related to changes caused in the gastrointestinal microbial community. Therefore, we must reconsider the negative consequences that disruption of the microbiome has in the biology of metazoans (dysbacteriosis). Alternations of the intestinal microbiota composition in animals can be caused by multiple factors, including the misuse of antibiotics, having as a result a negative impact on the development and function of the immune, endocrine, nervous, and digestive systems. For this reason, social concerns regarding the development of antibiotic-resistant microorganisms have resulted in an urgent necessity to find feasible alternatives to maintain animal health and performance without the use of antibiotic growth promoters (AGP), in order to sustain livestock production as an economically viable source of food for human consumption. Hence, research about AGP alternatives such as probiotics, prebiotics, phytochemicals, organic acids, enzymes, and vaccines has become a priority for many scientists around the world.

Abstract

In livestock species, breeding goals are aimed primarily at improvement of production traits. However, there are a number of examples where selection for high production efficiency has resulted in reduced welfare through unfavorable outcomes in health and fitness characteristics. These effects raise questions about what is ethically acceptable in animal breeding. Welfare problems may be experienced when physiological balance is disturbed by genetic selection for high production alone, by a mismatch between the environmental challenges and the range of coping responses available to an animal, or from a mismatch between the animal’s needs and their degree of satisfaction. This may be resolved by either improving the environment to support the animal, but also by providing the animal, through genetic selection, with means to adapt to the production environment. The Standing Committee of the European Convention for the Protection of Animals kept for Farming Purposes emphasizes that breeding goals should include health and welfare. The Farm Animal Welfare Council pleas for a greater emphasis in breeding programs on traits associated with good welfare. However, although breeding goals in most farm animal species have been broadened beyond production traits to include functional traits, behavioral traits are rarely included despite their potential to improve animal production and welfare. It is the goal of the present Research Topic to bring together experimental and theoretical research focusing on the genetics of welfare traits and the possibility to improve animal welfare through selection. This topic presents an overview of the relationship between selection for high production and livestock robustness, examples of improving robustness through the introduction of novel traits in livestock breeding, and a discussion on selection methods to address welfare issues. The discussion on sustainability of breeding practices is very alive today and will remain to be an important part of the debate in the future.

Abstract

Cet ouvrage rend compte de la façon dont les dynamiques de changements de pratiques des agriculteurs sont liées à la structure des réseaux de dialogues professionnels dans lesquels ils sont insérés. Développant une analyse des réseaux sociaux, il montre comment, du fait de certaines caractéristiques de ces réseaux, les agriculteurs se trouvent socialement plus ou moins bien armés pour mettre en œuvre de nouvelles pratiques plus respectueuses de l’environnement.

Abstract

This book looks at key research covering a wide range of aspects of environmental sustainability and the mitigation of environmental impacts of livestock production, including emissions of greenhouse gases (carbon dioxide, methane, nitrous oxide), nitrogen and phosphorus excretion, ammonia emissions, land use and land management, and use of energy and other resources. All the globally most important livestock species (beef and dairy cattle, pigs, broiler chicken and laying hens) are covered in the book. The mitigation methods assessed in the papers include general system changes, changes in feeding, improvement of animal health, and new technologies of manure management. The scope of the papers included in this book ranges from farm level mitigation methods to national level system changes. This book also addresses methodological development in assessing the environmental sustainability of the livestock production chains, including holistic methods, such as environmental and social life cycle assessment (LCA) and other modeling approaches.

Abstract

Open-source electronics are becoming very popular, and are integrated with our daily educational and developmental activities. At present, the use open-source electronics for teaching science, technology, engineering, and mathematics (STEM) has become a global trend. Off-the-shelf embedded electronics such as Arduino- and Raspberry-compatible modules have been widely used for various applications, from do-it-yourself (DIY) to industrial projects. In addition to the growth of open-source software platforms, open-source electronics play an important role in narrowing the gap between prototyping and product development. Indeed, the technological and social impacts of open-source electronics in teaching, research, and innovation have been widely recognized.

Abstract

Food insecurity is a complex ‘wicked’ problem that results from a range of unstable and uncertain physical, social, cultural and economic factors that limits access to nutritious food. Globally, 800 million people are under-nourished, and around 2 billion are overweight/obese or have micronutrient deficiency. These populations are largely positioned in developing countries where disease burden is high and impacts health budgets and productivity. Similarly developed countries, cities and neighbourhoods are experiencing a greater emergence of vulnerable populations. This is in part explained by the change in the food production and manufacturing, the retraction in economic climates, the increase in food price, and in some regions reduced food availability and access.Vulnerable groups include but are not limited to migrant populations, Indigenous people, elderly, pregnant women, those with disability, homeless, young children and youth. Poor nutrition at significant periods of growth and development and during life impact long term health outcomes increasing non-communicable disease prevalence, health cost and reducing economic productivity.
