| Abstract | espanolSe realizaron dos ensayos para evaluar el efecto de dietas con diferentes niveles de factores antinutritivos: inhibidores de tripsina y quimotripsina (UTI, UQI respectivamente, como unidades) de guisantes de invierno y γGlutamyl-S-Ethenyl-Cysteine de alberjon, en el rendimiento de lechones durante el perio - do estarter. En cada uno se utilizaron 192 machos castrados, hibridos Duroc x (Large-White x Landrace), con 11,23 y 11,55 kg de peso medio respectivamente, e igual diseno: cuatro tratamientos y ocho replicas cada una de seis lechones. Los tratamientos del Ensayo 1 fueron: Control: harina de soja 47 y soja ex - trusionada (0,97 UTI-1,94 UQI/mg de pienso); P-CAR: soja extrusionada y guisante Cartouche (1,62 UTI3,16 UQI/mg de pienso); P-ICE: soja extrusionada y guisante Iceberg (3,09 UTI-4,95 UQI/mg de pienso); P-LUN: soja extrusionada y guisante Luna (3,19 UTI-5,56 UQI/mg de pienso). Los lechones del tratamiento P-CAR crecieron significativamente mas que el resto, con igual consumo y conversion. No hubo diferencias entre Control, P-ICE y P-LUN. El pienso del Ensayo 2 incluia diferentes niveles de alberjon: 0%, 5%, 15% y 25%, y en consecuencia de γGlutamyl-S-Ethenyl-Cysteine (1,52% del grano). Los lechones del tratamiento 5% comieron y crecieron mas, con igual conversion que los del tratamiento 0%. El rendimiento empeoro con porcentajes del 15% o mayores. Se concluye que lechones de 40 a 61 dias de vida mantienen o mejoran el rendimiento con la ingesta de inhibidores de proteasas que exceden 3,28 y 2,86 veces, UTI y UQI respectivamente, los de una dieta de soja, y que la inclusion de 5% de alberjon en el pienso aumenta el consumo y el crecimiento EnglishTwo trials were conducted to evaluate the effect of diets with different levels of anti-nutritional factors: trypsin (TIU) and chymotrypsin (CIU) inhibitors units of peas and γGlutamyl-S-Ethenyl-Cysteine (GEC) of narbon vetch, in productive performance of pigs from 40 to 61 days of age. 192 barrows were used in each test, Duroc hybrid x (Large White x Landrace), with 11.23 and 11.55 kg body weight respectively, and the same experimental design: four treatments and eight replicates with six piglets in each case. In trial 1 treatments were: Control: soybean meal 47 and soybean extruded (0.97 TIU-1.94 CIU/mg feed); P-CAR: soybean extruded and pea Cartouche (1.62 TIU-3.16 CIU/mg feed); P-ICE: soybean extruded and pea Iceberg (3.09 TIU-4.95 CIU/mg feed); P-LUN: soybean extruded and pea Luna (3.19 TIU-5.56 CIU/mg feed). The piglets of P-CAR treatment grew significantly faster than the others, with the same intake and feed conversion. No significant differences between Control, P-ICE and P-LUN. In trial 2 the feedstuff had different levels of narbon vetch: 0%, 5%, 15% and 25%, and consequently of γGlutamyl-S-Ethenyl-Cysteine (1.52% of the grain). The piglets that consumed the treatment of 5% had higher intake and growth, and the same conversion that piglets feeding with the treatment of 0%. The performance worsened significantly with increasing 15%. We conclude that piglets in starter period maintain or improve the performance with intake of proteases inhibitors in feedstuff that exceed 3.28 (TIU) and 2.86 (CIU) times those of a control diet, and that the inclusion of 5% of narbon vetch in feedstuff increases feed intake and growth |
