Adisseo updates amino acids requirements for poultry, pigs and aqua
Adisseo, the nutritional solution provider for animals, has published the new Rhodimet Nutrition Guide, with regrouped amino acids requirements for poultry, swine and aquaculture.
Poultry includes broilers, pullets, laying hens, turkeys and ducks; swine includes piglets, growing-finishing pigs, gilts, gestating and lactating sows and entire males; and aquaculture includes freshwater fish, marine fish and shrimp.
A meta analysis has been lead on experiments designed with at least four amino acid levels. The recommendations are expressed in digestible amino acids, and when not available on total amino acids.
Based on a model approach developed in 2002(1) and 2005 (2) by Pierre Andre Geraert (currently Innovation Marketing Director at 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. As an example, the minimum digestible amino acid intake of pigs in relation with average daily gain from 3kg to 115 kg are shown in Figure 1.
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.
A flipchart of this booklet is available on the Adisseo's web platform FeedSolutions.adisseo.com.
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.
