INRA Feeding Systems for Ruminants
Langue : Anglais
Auteurs : SAUVANT Daniel, SAUVANT Daniel, NOZIÈRE Pierre
The INRA Feeding System for Ruminants has been renewed to better address
emerging challenges for animal nutrition: prevision of productive
responses, product quality, animal health and emissions to the
environment, in a larger extent of breeding contexts. The new system is
mainly built from meta-analyses of large data bases, and modelling. The
dietary supply model accounts for digestive interactions and flows of
individual nutrients, so that feed values depend on the final ration.
Animal requirements account for variability in metabolic efficiency.
Various productive and non-productive animal responses to diets are
quantified.
This book presents the whole system for dairy and meat, large and small ruminant production, including specificities for tropical and Mediterranean areas.
The first two sections present biological concepts and equations (with their field of application and statistical accuracy) used to predict intake (including at grazing) and nutrient supply (Section 1), animal’s requirements and multiple responses to diets (Section 2). They apply to net energy, metabolisable protein and amino acids, water, minerals and vitamins.
Section 3 presents the use of concepts and equations in rationing with two purposes: (1) diet calculation for a given performance objective; and (2) prediction of the multiple responses of animal to diet changes.
Section 4 displays the tables of feed values, and their prevision. All the equations and concepts are embedded in the fifth version of INRAtion® software for practical use.
