Summary:

The latest edition of Nutrient Requirements of Dairy Cattle includes many improvements over the 1978 edition. The most significant advance in Nutrient Requirements of Dairy Cattle is a computer program, provided on diskette, that includes all requirements for energy, protein, calcium, phosphorus, and vitamins A and D. It is compiled to run on PC-DOS or MS-DOS on IBM-compatible personal computers. A diskette accompanies each book. Within the book, dry matter intake and energy concentration assumptions have been made more consistent from table to table. A major change involves the expression of protein requirements on the basis of degradable and undegradable intake protein and includes two systems to determine protein requirements. A new table enables users to find data for a cow that resembles their own animals and locate their specific energy, protein, and other dietary requirements. Other tables have been expanded to include data on the nutrient requirements during the 3 weeks of lactation and for cows with higher milk yields.
