Pea protein as a substitute of soybean protein in diets for young pigs: effects on nutrient digestibility and digestive traits
Research Areas
  • Animal production
A trial was conducted to study the effects of using pea protein concentrate (PPC), soybean meal (SBM) or fullfat soybean (FFSB) as a substitute J. Anim. Sci. Vol. 86, E-Suppl. 2/J. Dairy Sci. Vol. 91, E-Suppl. 1 179 of soy protein concentrate (SPC) on coefficient of ileal apparent digestibility (CIAD) of nutrients and digestive traits of piglets. The design was completely randomized with four treatments and six replicates of one piglet each. Four isonutritive diets (2,490 kcal NE/kg and 1.28% available Lys) were formulated and fed to pigs from 26 to 48 d of age. The main difference among these diets was the protein source used. In all cases the source tested supplied 5.5% of the dietary protein (CP). The CIAD of dietary components, the pH of the gastro intestinal tract (GIT), and the weight of digestive organs and spleen were measured at 48 d of age. Protein source had no effect on CIAD of CP or amino acids. However, the CIAD of organic matter (0.813 and 0.813 vs. 0.789 and 0.768) and gross energy (0.810 and 0.816 vs. 0.789 and 0.768) was greater for pigs fed SPC and SBM than for pigs fed PPC and FFSB (P¡Ü0.01). The weight of the GIT was greater for pigs fed FFSB and PPC than for pigs fed SBM with pigs fed SPC being intermediate (61.0, 60.3, 52.8, and 55.9 g/kg body weight, respectively; P¡Ü0.05). The poorer nutrient digestibility observed in pigs fed PPC and FFSB as compared to pigs fed SBM or SPC might be related to the higher TI content of these protein sources (4.9 and 4.7 vs. 2.7 and 1.6 g/kg). In summary, the inclusion of pea protein concentrate and fullfat soybean in the diet impairs ileal digestibility of organic matter and gross energy at 48 d of age. The replacement of soya bean meal by pea protein or soy protein concentrate in piglet diets, to improve nutrient digestibility, is not justified.
