Major changes have recently taken place in the value attached to components of milk. Although approximately half the energy in milk is contained in fat, fat is rapidly decreasing in value relative to protein. This has come about because of the increased availability of competitively-priced, plant-derived edible oils and because of the perceived health problems associated with animal fat in the human diet. Such changes have major implications for the dairy sector, particularly in developed countries. Against this background, this book presents a timely review of developments in milk production and consumption, of changes in milk component values, and of the opportunities that biotechnology provides to alter the composition of and add value to milk on the farm. The subject coverage is very broad, ranging from nutritional aspects of pastures and forages, to rumen microbiology, genetics and reproductive technologies, milk biochemistry and environmental implications. It is based on a conference held in Wellington, New Zealand, in February 1996, and sponsored by the OECD and AgResearch. Contributors include leading research workers from North America, Europe, Japan, Australia and New Zealand. It provides an invaluable overview of the subject, suitable as a reference book for advanced students, researchers and advisers in dairy science as well as related disciplines such as grassland, nutritional and food sciences.

This report reviews the energy and protein requirement systems for dairy cows currently used in Britain and presents a new approach, along with the outline of a model for its implementation. Current systems give little consideration to the responses of the animal to changes in the nutrient supply, or to interactions between dietary constituents in their effects on digestion and metabolism. Neither do they predict any effect on the partition of nutrient use between milk and body, or changes in the yields of milk fat, protein and lactose, which determine the commercial value of the milk. Therefore the systems, although not inaccurate, lack relevance to the current needs of UK milk producers. Models which embody concepts of nutrient supply and utilization are reviewed and their development as viable alternatives is considered. It is concluded that a new diet formulation system for dairy cows should aim to predict voluntary feed intake, the partition of nutrient use between milk production and tissue deposition, and the short and long-term of effects of nutrition on fat, protein and lactose yields. The physical and biological characteristics of the cow must also be recognized and incorporated into any model for response prediction. The report is also published in Nutrition Abstracts and Reviews - Series B: Livestock Feeds and Feeding. It is an authoritative review for advanced students, research workers and advisors in animal nutrition and in dairy science and technology.

This new edition follows the successful structure of the first edition bringing together information on a wide range of fermented dairy products. It takes particular account of the profound influence that modern biotechnological sciences are having on the traditional biotechnology of dairy fermentations. For example, the taxonomy of lactic acid bacteria and of dairy pathogenic bacteria has been revolutionized in the past decade by the adoption of molecular biology techniques. Another important feature is the inclusion of a new chapter on the sensory evaluation of dairy flavors. This is a book for dairy scientists and technologists, both industrial and academic, particularly food chemists, dairy microbiologists and biotechnologists. It will also be an essential reference source for those in product development, processing and marketing, as well as regulatory officials in dairy companies and government laboratories.
