The aim of this trial was to compare pea protein concentrate, soya protein concentrate, regular soya bean meal and fullfat soya bean as a source of dietary protein on performance, faecal and ileal digestibility and digestive traits of young pigs. It was found that the inclusion of 10.5% raw pea protein concentrate (4.9 g TI/kg) in the diet reduces growth performance in pigs from 26 to 36 days of age and nutrient digestibility at 48 days of age. The inclusion of 15.8% fullfat soya bean (4.7 g TI/kg) also reduces performance and nutrient digestibility as compared to soya protein concentrate (1.6 g TI/kg) or regular soya bean meal (2.7 g TI/kg). The inclusion of soya protein concentrate at the expenses of soya bean meal did not elicit a clear positive response on piglet growth or nutrient digestibility. Therefore, the use of raw pea protein concentrate and fullfat soya bean high in trypsin inhibitors should be restricted in diets for young pigs.
