This book was released on 2008-10-17 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fitness and adaptation are fundamental characteristics of plant and animal species, enabling them to survive in their environment and to adapt to the inevitable changes in this environment. This is true for both the genetic resources of natural ecosystems as well as those used in agricultural production. Extensive genetic variation exists between varieties/breeds in a species and amongst individuals within breeds. This variation has developed over very long periods of time. A major ongoing challenge is how to best utilize this variation to meet short-term demands whilst also conserving it for longer-term possible use. Many animal breeding programs have led to increased performance for production traits but this has often been accompanied by reduced fitness. In addition, the global use of genetic resources prompts the question whether introduced genotypes are adapted to local production systems. Understanding the genetic nature of fitness and adaptation will enable us to better manage genetic resources allowing us to make efficient and sustainable decisions for the improvement or breeding of these resources. This book had an ambitious goal in bringing together a sample of the world’s leading scientists in animal breeding and evolutionary genetics to exchange knowledge to advance our understanding of these vital issues.

Download or read book Animal Breeding Plans written by Jay L. Lush and published by Read Books Ltd. This book was released on 2013-04-18 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

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.

Download or read book Local cattle breeds in Europe written by Sipke Joost Hiemstra and published by BRILL. This book was released on 2023-09-04 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: The majority of cattle breeds in Europe are native or local breeds, usually characterised by a limited geographical distribution. The breeds have significant potential as they are carrying large amounts of genetic variation and have important cultural, historical, socio-economic and environmental values. 'Local cattle is living inheritance, old germplasm which shouldn't get lost', said one farmer. These breeds were once regionally the most popular ones, now many of them are 'at risk'. Hence, there is a need to (further) develop effective policies and strategies at national and European level to conserve and develop local cattle breeds and to promote their branded use. The European local cattle populations were a target in the EURECA project, co-funded by the European Commission. The aim was to better understand the state of the breeds, to identify factors that contribute to their success or failure and to recommend decision-making tools for development of ambitious and sound strategies and policies. With this full colour publication we share the methodology and give a comprehensive view on European local cattle breeds. We hope that our findings and recommendations will contribute to the development of successful future strategies for local cattle breeds in Europe. 'The cows are like diesel cars; Slow start, cheap energy and long life'.
