Book Description
Nutrition and Lactation in the Dairy Cow is the proceedings of the 46th University of Nottingham Easter School in Agricultural Science. Said symposium was concerned with the significant advances in the field of nutrition and lactation in the dairy cow. The book is divided in five parts. Part I deals with the principles behind nutrition and lactation of cows. Part II discusses the cow's nutrient interactions; responses to nutrients that yield protein and energy; and the influence of nutrient balance and milk yields. Part III tackles the efficiency of energy utilization in cows and its relation to milk production. Part IV talks about food intake of cows and the factors that affect it, while Part V deals with the different feeding systems for cows. The text is recommended for those involved in raising cows and dairy production, especially those who would like to know more and make studies about the relationship of nutrition and lactation of cows.

Book Description
This book is about resource allocation matters with the aim to further development thoughts and models on resource allocation applied to livestock production. It contains 18 chapters divided into 4 parts which discuss resources and resource allocation patterns, trade-offs, metabolic constraints to resource allocation and the process of homeorhesis with a special emphasis to homeorhesis during heat stress; the relationship between food intake and resources allocated to body maintenance, growth, reproduction and the immune response; the consequences of high production efficiency in pigs, poultry and dairy cattle and the consequences of improved production by means of biological engineering and options to include resource allocation matters in the breeding objective, animal welfare and in resource allocation modelling.

Book Description
This book fills the gap between textbooks of quantitative genetic theory, and software manuals that provide details on analytical methods but little context or perspective on which methods may be most appropriate for a particular application. Accordingly this book is composed of two sections. The first section (Chapters 1 to 8) covers topics of classical phenotypic data analysis for prediction of breeding values in animal and plant breeding programs. In the second section (Chapters 9 to 13) we provide the concept and overall review of available tools for using DNA markers for predictions of genetic merits in breeding populations. With advances in DNA sequencing technologies, genomic data, especially single nucleotide polymorphism (SNP) markers, have become available for animal and plant breeding programs in recent years. Analysis of DNA markers for prediction of genetic merit is a relatively new and active research area. The algorithms and software to implement these algorithms are changing rapidly. This section represents state-of-the-art knowledge on the tools and technologies available for genetic analysis of plants and animals. However, readers should be aware that the methods or statistical packages covered here may not be available or they might be out of date in a few years. Ultimately the book is intended for professional breeders interested in utilizing these tools and approaches in their breeding programs. Lastly, we anticipate the usage of this volume for advanced level graduate courses in agricultural and breeding courses.

Book Description
An understanding of sustainability in animal production is becoming increasingly necessary since the global demand for food is expected to dramatically increase in the coming decades. In this context, raising animals for the production of food will become increasingly challenging. Farm animals should not adversely compete with humans for their own sustenance, and food of animal origin should be safe and affordable. The production of healthy animals will therefore be a prerequisite. Such animals will efficiently convert their feed into food that can be certified as nutritive and safe. In addition there is growing evidence that there should be a focus on animal welfare, and environmental pollution related to animal farming must be minimized. Indeed the equation to resolve the constraints on animal production is complex and multifactorial. It is inarguable that the environment and the feed that is offered to animals, are key elements of sustainability in livestock and poultry production. This book addresses the major issues related to animal health and welfare maintenance in relation to their environment, as well as housing emissions and waste management. Experiments, reviews and expert opinions and scenarios for the future are presented. Each of the chapters has been written by scientists with international reputations. The language used, and the examples and the illustrations provided, make it easy to read. The book is of major and current interest to teachers and students in animal and veterinary sciences and to professionals: veterinarians, farm managers, agricultural advisers worldwide.
