Animal nutrition


The availability of feed-use amino acids allows the nutritional requirements of animals to be met with a high degree of precision and the dietary crude protein (CP) content to be reduced with confidence. This reduction of dietary CP is efficient, i.e. without deteriorating the growth performance, only when the dietary indispensable amino acids content is controlled and their profile is balanced.

Besides its positive effect on health, and particularly on the reduction of diarrhoea incidence, reducing the dietary CP through the use of feed-use amino acids is recognized as one of the Best Available Technique to limit the excretion of nitrogen in the environment from husbandry, without compromising growth.

It is then the nutritionist’s and formulator’s task to design and produce recipes that supply the optimal quantity of amino acids to answer the estimated amino acids requirements of animals. Achieving this objective lies in the fulfilment of the following steps:

  • estimation of the amino acids contents of feedstuffs, the associated variability and their availability for animals,
  • estimation of the amino acids requirements of animals that allow the full expression of their genetic potential,
  • usage of the most advanced energy system that takes into account the successive steps of metabolism.
