Animal models

Dairy cow model

Metabolisable Energy (ME) and Metabolisable Protein (MP) requirements from the UK Feed into Milk (FiM) system. 
(Feed into Milk - A new applied feeding system for dairy cows. Published by Nottingham University Press, 2004).

ME supply calculated from UK feed tables generated from sheep digestibity values. 
MP supply calculated from 3 pool rumen model outlined in Feed into Milk.

Decisions Support Systems (DSS) for amino acid requirements, rumen pH prediction and milk compositional change prediction all  derived from Feed into Milk.

Extra dairy nutrients

DCAB - Dietary Cation Anion Balance, Rumen starch and bypass starch, NDF from forage, Starch plus sugar.

Growing beef and heifers

ME and MP supply and requirements from AFRC Energy and Protein Requirements of Ruminants  (Published by CAB International 1993).

Vitamin and Mineral requirements

Reviewed by DietCheck Ltd (2007) from UK requirements (1984 & 1991), The Mineral Nutrition of Livestock (Underwood & Suttle, 1999), NRC 2001 and other published information.
