A total of one hundred forty-four crossbred pigs PIC-L65 x (Large White x Landrace) with an initial BW of 7.08 ± 0.16 kg (28 ± 2 days of age) were used to assess the substitution of soybean meal (SBM) by pea (Pisum sativum) or narbon vetch (Vicia narbonensis). There were three experimental diets (24 total replicas and six pigs per replicate) with gilts and barrows, and the same levels of energy and protein: 1) 21.5% soybean meal 47 (SBM); 2) 5% narbon vetch + 19.8% SBM and 3) 24% winter pea Chicarron + 12.1% SBM. We evaluated the effect of anti-nutritional factors: protease inhibitors in pea and narbon vetch (trypsin, TIU; CHYMOTRYPSIN, CIU), and the dipeptide y-Glutamyl-S-Ethenyl-Cysteine in narbon vetch. In the overall period (28 to 64 days of age) pigs fed with diet 3) improved ADG and FCR (P<0.05) without changing the ADFI. The piglets fed with diets 1) and 2) had the same productive results. There were no significant differences due to sex. We conclude that, in our experimental conditions, the piglets during the transition phase (28-64 days of age) tolerated diets with 5% of narbon vetch and improve performance with 24.7% of winter pea Chicarron and levels of TIU three times higher than a control diet, substituting partially SBM of diet.
