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.

This book is the most comprehensive introductory text on the chemistry and biochemistry of milk. It provides a comprehensive description of the principal constituents of milk (water, lipids, proteins, lactose, salts, vitamins, indigenous enzymes) and of the chemical aspects of cheese and fermented milks and of various dairy processing operations. It also covers heat-induced changes in milk, the use of exogenous enzymes in dairy processing, principal physical properties of milk, bioactive compounds in milk and comparison of milk of different species. This book is designed to meet the needs of senior students and dairy scientists in general.

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.
