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 A Crossbreeding Experiment with Dairy Cattle written by Milton Henry Fohrman and published by . This book was released on 1954 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1939, when the Bureau of Dairy Industry began its crossbreeding experiment at Beltsville, the published information on the crossbreeding of dairy cattle was slight, unimpressive, and very little of it was based on experimental results. The crossbreeding investigations at Beltsville were undertaken to develop knowledge on the subject which would provide a sound basis for advising the operators of milk-producing farms what to expect if they used crossbreeding in hopes of producing better replacements for their milking herds. Final results on any dairy cattle breeding research project cannot be published until the last animal on the project has died, so this report covers the breeding performance and milk and butterfat production on all individuals used on the project which have had time to complete a normal first-lactation period.
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.

This book was released on 2013 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: Greenhouse gas emissions by the livestock sector could be cut by as much as 30 percent through the wider use of existing best practices and technologies. FAO conducted a detailed analysis of GHG emissions at multiple stages of various livestock supply chains, including the production and transport of animal feed, on-farm energy use, emissions from animal digestion and manure decay, as well as the post-slaughter transport, refrigeration and packaging of animal products. This report represents the most comprehensive estimate made to-date of livestocks contribution to global warming as well as the sectors potential to help tackle the problem. This publication is aimed at professionals in food and agriculture as well as policy makers.
