Book Description
The main goal of this book is to share knowledge on milk production and reproductive performances of cross-bred cattle and the effect of both genetic and non genetic factors on these performances based on research results which are conducted in different areas on different cross- bred cattle. Production environments vary as a result of different management practices and constantly changing climatic conditions leading to variability in animal performance. An animal of high genetic value may perform dismally when the production environment is not right due to the negative interaction between the animal's genes and its environment. This book is made up of two parts; the first part contain daily milk yield, lactation milk yield and lactation length of different cross-breds with reasonable explanation and factors affecting this performances. The second part provides good information on reproductive performances of cross-bred cattle and the effect of both genetic and non genetic factors on this performance based on research results. Both parts have useful information for researches, dairy business man and for lectures.

Book Description
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.
