    Ideal Amino Acid Profile and Low Crude Protein Diets For Fattening Pigs

    In pig production, reducing the dietary crude protein level by using feed-grade amino acids is an extremely efficient strategy to contribute to the three pillars of sustainability: Economy, Environment and Society concerns. The use of L-Tryptophan in fattening pig diets makes possible the achievement of low crude protein levels with optimized performance. Moreover, it allows a more precise optimization of the formula with a reduction of the feed cost, leads to a lower nitrogen excretion by the animals, which decreases acidification and eutrophication, and offers an opportunity to use more local feedstuffs instead of imported soybean meal, mitigating the impact of the pig production on global warming potential. To contribute to a more sustainable pig production, balancing the amino acids profile as recommended by Ajinomoto Animal Nutrition Europe is necessary to maintain growth performance and carcass quality when the dietary crude protein level is reduced.

    In order to make the optimal choice on the amino acids levels to apply in the formula, recent advances on amino acids nutrition are detailed in this document and an updated ideal amino acids profile is given. Practical implementations of this amino acids profile in low protein fattening pig diets are also described.
