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.

Available in PDF, EPUB and Kindle. Book excerpt: Wood surface attributes can be established by examining its several different physical or chemical properties. Differences in the wood surfaces occur between the manufacturing and post-treatment processes as well. Understanding how their unique anisotropic molecular organization, chemical linkages, branching, and other molecular features govern micro- and macroscale accessibility is essential for coating and complex modification processes. It is therefore important for scientific as well as practical reasons to qualify and quantify the effects of wood surface treatments and modifications. Challenges still exist to fully understanding the effect of the numerous applied chemicals and the wide range of treatment processes on wood surfaces.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Heredity of Dual Purpose Cattle: A Study in Farm Economics Based on Red Polled Records From 1808 to 1915 The fact that full particulars of the formation and development of a new breed of cattle in the last century are yet available is my apology for presenting the following essay on the Heredity of Dual Purpose Cattle as illustrated by the Red Polled. In preparing the facts and figures which are set forth in the narrative, I have been fortunate in working upon a system of registration of pedigree unlike any form that existed before the year 1874. The plan was feasible from the fact that the Norfolk and Suffolk Polled Cattle were not being bred outside the borders of the two counties. Also that it was possible to glean evidence from men who had both seen and aided in the inter fusion of the old variety and the new; that had been skilfully evolved from the mixture of two types of cattle that had existed in Norfolk from the olden time. That the new variety has won a permanent place in the world is evidenced by the fact that while in 1874 there were only four Red Polled Cattle in America, and these imported in the previous December, the issue of the American edition of the Herd Book, which contains names, number, and pedigree of the cattle born in the year ending December 31 st, 1915, contains the register of Bulls 27083 to 28851, of Cows 40265 to 42651. At the close of the year 1889 there were 132 bulls and 276 cows. In the following three years, when American breeders had begun a co-operation of registration with the British, the number had been increased by 849 bulls and 996 cows. Of the total register in Vols. 7 to 18, the American registry was some 7, 500 bulls and 9, 000 cows. The Red Polled Cattle Club of America had its separate register as from January, 1901, opening with the bull register number 8909, cow register number 17878. There has thus been an increase in the last fifteen years of Red Polled Cattle in use in the United States (a very few only in the Dominion of Canada): Bulls 19, 943, cows, 24, 774. Professor C. H. Eckles, of Missouri, in his book on "Dairy Cattle and Milk Production," says of the Red Polled in America: - "They have won their way entirely by their merits, and are increasing rapidly in those States where dual-purpose cattle are in demand. They are the most typical and most popular of the real dual-purpose breeds." Further evidence of the practical value of the breed as it has spread abroad in the United States is seen in the pages now laid before the student of Farm Economics.

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.
