Nutrition and Lactation in the Dairy Cow

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.
