The new Rhodimet® Nutrition Guide
edited by Adisseo regroups the amino acids requirements for
- poultry: broilers, pullets, laying hens, turkeys and ducks,
- swine: piglets, growing-finishing pigs, gilts, gestating and lactating
sows, entire males,
- aquaculture: freshwater fish,
marine fish and shrimps.
The recommendations are expressed in
digestible amino acids, and when not available on total amino acids.
To achieve this new guide, Adisseo’s
Experts have realised an extensive review of literature for the last twenty
years (more than 200 articles for poultry and swine) and included most recent
discussions from the Advancia forums.
A meta analysis has been lead on
experiments designed with at least four amino acid levels.
Based on a
model approach developed by Pierre Andre Geraert, innovation marketing director, Adisseo, amino acids requirements are calculated according to weight gain of
growing animals or egg mass of layers.
The digestible amino acid
requirements are then expressed in gram of amino acid intake per animal and per
day, knowing that these requirements increase linearly with the average daily
gain or egg mass.
This methodology is also used, when
enough data are available for essential amino acids: methionine, threonine,
tryptophan, arginine, isoleucine and valine for broilers, laying hens, turkeys
and pigs requirements.
The recommendations for non essential
amino acids (cystine, alanine, praline, tyrosine, etc …), are calculated
according to an ideal protein profile, with lysine as the reference.
Very recent trials achieved by the BARC Institute in Thailand show that Adisseo’s new recommendations lead to
better economical results than the other sources available.
This Guide is an extract of the
upcoming electronic version of Rhodimet® Nutrition Guide, an interactive tool,
that allows nutritionists and formulators to calculate the amino acids
requirements of various animal species under different rearing conditions.
