All about amino acid digestibility for pigs

In the world of feed formulation for pigs, ‘digestibility’ is often reported on. What exactly does that mean, how is it calculated, why are there several types of digestibility – and why is ‘standardised ileal digestibility’ the one to watch for pig producers? Digestibility values are essential to know for good diet formulation. After all, only the digestible parts of amino acids are absorbed by the animals and can thus be utilised for protein synthesis. When formulating piglet diets,
