Available in PDF, EPUB and Kindle. Book excerpt: Cattle are domestic animals which have a special role of providing food for human consumption such as beef and milk. In addition, cattle are often chosen as animal models in biomedical and reproductive research. Holstein-Friesian cattle are known as the world's highest producing dairy breed. The Holstein-Friesian breed is differentiated from other dairy breeds based on its distinct characteristics such as high milk production, high calving survival, physiology, body size, and health. However, in the recent past, an increase in inbreeding has resulted in negative effects such as increased calving mortality, reduced milk production, diminished health quality, and decreased fertility. Inbreeding is the production of offspring from breeding within a population which has the same or closely related genetic makeup. Inbreeding results in increased homozygosity and reduced heterozygosity within the population. Therefore, management of inbreeding is necessary to obtain high value production and increased health and longevity in dairy cattle. Currently, genetic selection programs and assisted reproductive technologies, such as artificial insemination (AI), are utilized to increase genetic variations and decrease the impact of inbreeding depression which improves production, health, reproduction, and longevity of individuals.

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.
