Book Description
Gegenstand dieser Arbeit ist es, den Einsatz der genomischen Zuchtwertschätzung für neue funktionale Merkmale und den Gehalt an Milchinhaltsstoffen auf Ebene der einzelnen Euterviertel in der Milchrinderzucht zu beleuchten. Nach einer allgemeinen Einführung in die genomische Selektion und in das Prinzip der Testherden werden im zweiten Kapitel genetische Parameter und Heritabilitäten für verschiedene Verhaltensmerkmale, für Milchfluss, Eutertiefe, Labienlage und Tage bis zur 1. Brunst geschätzt. Im dritten Kapitel erfolgt eine Schätzung genetischer Parameter und Heritabilitäten für die Milchinhaltsstoffe (Fett, Eiweiß, Lactose, Harnstoff, SCS) und für Hyperkeratosen der Zitzen auf Basis der einzelnen Euterviertel. Ferner werden additiv genetische und phänotypische Korrelationen für diese Merkmale zwischen den Eutervierteln geschätzt. Im vierten Kapitel wird eine genomische Zuchtwertschätzung für die funktionalen Merkmale aus Kapitel eins auf Basis von 777k Genotypen vorgestellt. Die Sicherheit der genomischen Zuchtwerte wird zudem mit einem neuen Ansatz abgeleitet, der trotz geringer Sicherheit der konventionellen Zuchtwerte eine realistische Abschätzung der genomischen Zuchtwerte erlaubt. Im fünften Kapitel werden abschließend die Möglichkeiten beleuchtet, eine genomische Zuchtwertschätzung für funktionale Merkmale in einem Testherdensystem zu etablieren.

Book Description
High-throughput molecular technologies ("omics") can help to decipher the contributions of different physiological systems and identify candidate molecules that are representative of different physiological pathways thereby allowing the discovery of biomarkers. Notably, the omics technologies along with and computational methods, bioprospecting, and artificial intelligence will continue to lead to better understanding of biological mechanisms that are responsible for physical attributes, or phenotypes. Research breakthroughs obtained through these technologies can be used to enhance productivity of food animals, meet the increasing demand for animal-sourced foods, enhance high-quality nutrient availability, ensure nutrient safety, mitigate the effects of climate variability, and result in new technologies that provide continued improvement in food security worldwide. Such breakthroughs are an urgent necessity because over the past 50 years, there has been an unprecedented increase in the world’s population, which will reach ten billion by the year 2050. Innovative and technological advancements that enhance all aspects of food production will arise from basic, fundamental research. Besides food, animal by-products have found many applications in the fields of pharmaceuticals, cosmetics, and household and industrial products. Hence, the need to ameliorate the productivity, reproductivity, growth performance, and disease resistance in animals has created a worldwide interest in gaining a deeper understanding of animal biology, biotechnology and genomics, and proteomics. The present volume thoroughly discusses the omics studies in domestic and non-domestic animals and their role in mitigation of various challenges ahead. The volume thus focuses on i. Omics (genomics, proteomics, transcriptomics, metabolonomics) technologies in identifying, characterizing biodiversity ii. Role of molecular techniques for improvement of domestic and non-domestic organisms iii. Animal and alternative model systems (using stem cells, tissue engineering, cell free systems, 3D platforms etc.) for studying life phenomena iv. Genetically modified organisms as factories for the products

Book Description
Over the past century, we have made great strides in reducing rates of disease and enhancing people's general health. Public health measures such as sanitation, improved hygiene, and vaccines; reduced hazards in the workplace; new drugs and clinical procedures; and, more recently, a growing understanding of the human genome have each played a role in extending the duration and raising the quality of human life. But research conducted over the past few decades shows us that this progress, much of which was based on investigating one causative factor at a time—often, through a single discipline or by a narrow range of practitioners—can only go so far. Genes, Behavior, and the Social Environment examines a number of well-described gene-environment interactions, reviews the state of the science in researching such interactions, and recommends priorities not only for research itself but also for its workforce, resource, and infrastructural needs.

Book Description
First published in 1943, “Animal Breeding Plans” contains a detailed guide on animal breeding designed for students with experience of genetics, embryology, breeds, and stock judging. It aims to furnish the reader with a clear understanding of the means available for improving the heredity of farm animals, especially what each possible method will or will not do well. Highly recommended for modern farmers and animal breeders. Contents include: “Origin and Domestication of Farm Animals”, “Consequences of Domestication”, “Beginning of Pedigree Breeding Methods in the United States”, “History of Animal Breeding Methods in the United States”, “Relation of the Breed Association to Breed Improvement”, “Genetic Principles in Animal Breeding”, “Mendelian Basis of Inheritance”, etc. Many vintage books such as this are increasingly scarce and expensive. It is with this in mind that we are republishing this volume now in an affordable, modern, high-quality edition complete with a specially-commissioned new introduction on farming.

Book Description
Quantitative traits-be they morphological or physiological characters, aspects of behavior, or genome-level features such as the amount of RNA or protein expression for a specific gene-usually show considerable variation within and among populations. Quantitative genetics, also referred to as the genetics of complex traits, is the study of such characters and is based on mathematical models of evolution in which many genes influence the trait and in which non-genetic factors may also be important. Evolution and Selection of Quantitative Traits presents a holistic treatment of the subject, showing the interplay between theory and data with extensive discussions on statistical issues relating to the estimation of the biologically relevant parameters for these models. Quantitative genetics is viewed as the bridge between complex mathematical models of trait evolution and real-world data, and the authors have clearly framed their treatment as such. This is the second volume in a planned trilogy that summarizes the modern field of quantitative genetics, informed by empirical observations from wide-ranging fields (agriculture, evolution, ecology, and human biology) as well as population genetics, statistical theory, mathematical modeling, genetics, and genomics. Whilst volume 1 (1998) dealt with the genetics of such traits, the main focus of volume 2 is on their evolution, with a special emphasis on detecting selection (ranging from the use of genomic and historical data through to ecological field data) and examining its consequences.

Book Description
This publication provides an update on the current status of gene maps in different livestock and pet/companion animal species. The findings summarized in species specific commentaries and original articles testify the rapid advances made in the field of animal genomics. Of significant interest is the fact that current investigations are providing headways for two important and exciting research fronts: targeted high-resolution mapping leading to the application of genomic information in addressing questions of economic and biological significance in animals, and the initiation of whole genome sequencing projects for some of the animal species. Like in humans and mice, this will set the stage for a new level of research and real time complex analysis of the genomes of these species. Animal Genomics signifies the beginning of a new era in this field and celebrates the achievements of the past 20 years of genomics research. It will be of special interest to researchers involved in genome analysis - both gross chromosomal as well as molecular - in various animal species, and to comparative and evolutionary geneticists.
