The Brazilian perspective on real nutrient requirements.


Horacio Santiago Rostagno PhD
Universidade Federal de Viçosa

The summary below highlights the presentation by Prof. H. Rostagno delivered at the 2012 Alltech Symposium.

A series of research studies was conducted to update and improve on the Brazilian Tables for feed composition and nutritional requirements for poultry.  In the new 3rd edition of the Brazilian Tables* requirements for the most important nutrients are tabulated as daily amounts to optimize performance.  A factorial method was applied when possible, following the model: Nutrient requirement (g/day) = g for maintenance + g for production.
