National Animal Nutrition Program (NANP) Modeling: Animal Performance Information

posted on 2023-11-30, 08:14 authored by National Animal Nutrition Program

Data can be downloaded in Excel format. Tables include: 1. Studies (reference, publication year, location); 2. Treatments (treatment description, number of animals, species, stage of production; 3. IngrComp (Ingredient Composition information, % DM); 4. Intake (Intake of nutrients, kg or g/d); 5. Digesta (rumen and total tract digestibility measurements, N flow measurements); 6. Milk (milk production, days in milk); 7. MilkComp (milk protein, fat, and lactose); 8. BW (body weight, body condition score); 9. BodyComp (body protein and fat); 10. Gain (average daily gain); 11. Diet (ingredients and inclusion rates); 12. Calorimetry (energy balance measurements from calorimetry studies); 13. Gest (Conception rate, birth rate, days pregnant); 14. GestComp (fluid, uterus, and conceptus composition); and 15. Environment (temperature, relative humidity).

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.

  • Environmental Stress: [to follow]

  • Beef Digestiblity: [to follow]

  • USDA Beltsville Agricultural Research Center: The data are the product of over 20 years of energy and nitrogen balance studies conducted in the metabolism chamber facility maintained by USDA in Beltsville, MD.

This database is currently under construction; additional data and updates will be incorporated over time.
