Amino acid digestibility in plant based protein concentrates and in Peruvian super prime fish meal fed to weanling pigs

Anti-nutritional factors in soybean meal can result in a reduction in digestibility of amino acids. Therefore, the use of soybean meal is limited in diets for weanling pigs and fish meal and other animal protein sources are often used instead. However, technologically treated plant proteins or mixtures of proteins may also be used instead of animal proteins if the treatments employed have reduced or eliminated the anti-nutritional factors. An example of 2 new plant-based proteins are protein concentrate 56 (JPC 56) and Fish Meal Replacer Omega 3 (FMR Ω 3). Both proteins are produced by Joosten, (Ab Weert, The Netherlands), but there is no information about the digestibility of amino acids in these proteins. Therefore, an experiment was conducted to test the hypothesis that the apparent ileal digestibility (AID) and the standardized ileal digestibility (SID) of amino acids in JPC 56 and FMR Ω 3 are not different from AID and SID values in fish meal.
