Book Synopsis Functional and Genetic Characterisation of Major Effect Milk Composition Variants in Dairy Cattle by : Tania Alice Fink
Download or read book Functional and Genetic Characterisation of Major Effect Milk Composition Variants in Dairy Cattle written by Tania Alice Fink and published by . This book was released on 2017 with total page 570 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bovine milk production and composition traits are complex quantitative phenotypes, reflecting the interplay of many environmental and genetic factors influencing mammary and lactation biology. Despite a largely quantitative architecture, genetic mapping studies have identified a handful of major effect loci in dairy cattle, each containing a large number of trait-associated sequence variants. Identifying the specific variant causally responsible at these genetic signals requires extensive experimental follow-up, where many of the genomic regions implicate present no obvious candidate mutations. The association signal is instead represented by many non-coding variants that are difficult to functionally prioritise. The aim of the research described in this thesis was to investigate four such loci segregating in NZ dairy cattle, aiming to mechanistically link causative genes and variants to the milk production and composition effects. The results of this thesis describe the identification of expression quantitative trait loci at each of the four major associated regions, providing evidence that the variants responsible exert their phenotypic influence through the modulation of mammary gene expression. Further genetic and functional experiments were conducted to elucidate the mechanism by which the implicated variants impact gene expression. Highlights of this work include the demonstration of a new mechanism of effect for the largest and most highly cited causal mutation in the bovine literature. This work also reports the discovery of major milk production effects for a mutation previously only implicated in bovine growth and stature. This thesis also reports the development and optimisation of CRISPR-Cas9 mediated genome editing as a method for testing the function of regulatory variants directly. By presenting an efficient in vitro engineering approach in mammary cells, the work creates a framework to genetically isolate candidate variants, creating opportunities to study the major effect variants reported in this thesis, and investigate other as yet undefined milk composition loci. Taken together, the work presented in this thesis provides enhanced understanding of the mechanisms linking major effect genetic variants to bovine milk production and composition, and raises the profile of these and other variants as markers to incorporate in animal selection and breeding strategies.

Book Synopsis Animal farming and environmental interactions in the Mediterranean region by : Isabel Casasús
Download or read book Animal farming and environmental interactions in the Mediterranean region written by Isabel Casasús and published by Springer Science & Business Media. This book was released on 2012-03-26 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: Livestock production systems are the result of an interaction between domestic animals and the environment, modulated by man, that dates back to Neolithic times. As a consequence of this interaction among the wide diversity of animal resources, natural habitats and population needs, very different farming systems have developed across the Mediterranean Basin. Understanding the mechanisms and effects of these relationships is key to design the farming systems best adapted to each condition, guaranteeing an adequate balance between target animal production and environmental outcomes provided by these systems. This is indeed a multidimensional topic, influenced by animal genetics, feeding resources, flock management, and economic and social aspects inside and outside the household. Therefore, this book focuses on the basis of the animal-environment interactions and the impact of human activities on the type and magnitude of these interactions. In this context, the issue of sustainability of livestock production is evaluated considering economic, social and environmental aspects. This book contributes to upgrade the state of the art in Mediterranean conditions, providing indicators and procedures of application across a wide range of systems, and hence of interest for researchers, students and professionals concerned with livestock production and the environment.
Book Synopsis The Genetics of Cattle, 2nd Edition by : Dorian Garrick
Download or read book The Genetics of Cattle, 2nd Edition written by Dorian Garrick and published by CABI. This book was released on 2014-11-28 with total page 642 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the time of domestication more than 10,000 years ago, cattle have played an increasingly crucial role in the development of human civilizations. Progress has been quite remarkable since the turn of the century; the sequencing of the bovine genome in 2009 launched new avenues for furthering our understanding of theoretical and practical aspects of cattle genetics. Covering a vast array of questions, this book reviews major topics from molecular and developmental genetics, disease resistance and immunogenetics to genetic improvement of dairy and beef breeds, addressing all current problems in the field. This second edition includes a new team of authors and completely new chapters on the genetics of fat production, nutrition, feed intake and efficiency, growth and body composition. Fully updated throughout, it provides a valuable resource on cattle genetics for researchers, breeders, veterinarians and postgraduate students.
Book Synopsis Safety of Genetically Engineered Foods by : National Research Council
Download or read book Safety of Genetically Engineered Foods written by National Research Council and published by National Academies Press. This book was released on 2004-07-08 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Assists policymakers in evaluating the appropriate scientific methods for detecting unintended changes in food and assessing the potential for adverse health effects from genetically modified products. In this book, the committee recommended that greater scrutiny should be given to foods containing new compounds or unusual amounts of naturally occurring substances, regardless of the method used to create them. The book offers a framework to guide federal agencies in selecting the route of safety assessment. It identifies and recommends several pre- and post-market approaches to guide the assessment of unintended compositional changes that could result from genetically modified foods and research avenues to fill the knowledge gaps.
Book Synopsis Breeding for robustness in cattle by : Marija Klopcic
Download or read book Breeding for robustness in cattle written by Marija Klopcic and published by BRILL. This book was released on 2023-09-04 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past decade has revealed unfavourable trends in e.g. fertility, udder health and locomotion in some major dairy cattle breeds due to a large increase in production and insufficient consideration of functional traits in the breeding goals. Such unfavourable trends in some functional traits increase costs. Additionally, the enlargement of herds leads to less available labour time per individual cow. This asks for cows that are easy to handle. At the same time, society is demanding a higher welfare standard of animals. These contradicting developments have increased the desire for so called more robust animals. Robustness can be defined as 'the ability to maintain homeostasis in commonly accepted and sustainable herds of the near future'; or 'the ability of the cow to function well in the environment she lives in as well as in a wide range of climates and production systems'. This book contains a series of articles (26) dealing with the concept of robustness, including aspects like evolution, genetics, environment, animal health and welfare, and integrity. Besides the major functional traits also the links to energy balance, hot climatic conditions, and the attitude and input of stakeholders towards robustness as part of the breeding program are discussed. This book is the first attempt to summarise the available knowledge concerning this topic in cattle, making this book unique. The contributions are from authors of 16 countries from all over the world. However, the focus is presently on farm animal level, while in future robustness of the whole production system may also require additional attention.
