Component data sets:

• NRC Dairy Report: The data summarized in this set were compiled and used for derivation of the mathematical model published in Nutrient Requirements of Dairy Cattle: Seventh Revised Edition, 2001 prepared by the Subcommittee on Dairy Cattle Nutrition, Committee on Animal Nutrition, National Research Council.

• Lofgreen Garrett: The data summarized in this set were a product of the research conducted by Dr. G.P. Lofgreen and Dr. W.N. Garrett both of the University of California, Davis. The data were collected in 5 comparative slaughter trials conducted over 4 years.
