Were used a total of 192 Duroc hybrid barrows, with 61 days-old (22.1 kg), which were slaughtered with 167 days of age (121.0 kg). There were three varieties of peas in diets: Cartouche (CAR), Iceberg (ICE) and Luna (LUN), with 9.87, 5.75 and 12.55 trypsin-inhibited units (UTI/mg) and 10.16, 8.62 and 15.75 chymotrypsininhibited units (CIU/mg), respectively. The design, in completely randomized blocks, had four treatments according the pea included in the diet: control (with soybean), CAR, ICE and LUN diets, with 12 replicates of four pigs per treatment. At the end of the experimental period, pigs fed the control diet were heavier (P < 0.01) and showed higher daily weight gains (P < 0.01) and daily feed intake (P < 0.05) than those fed CAR and LUN diets, with those that received the ICE diet in an intermediate position. These results are mainly due to the first periods (from 61 to 83 days of age), because growth performances were scarcely affected later. No influence of the diet was observed on carcass and meat quality (P > 0.10). It concludes that winter peas with 5.75 TIU/mg and 8.62 CIU/mg, can replace soybean from 84 to 167 days of age, without affecting yield, carcass quality, main lean cuts and intramuscular fat loin content and major fatty acids proportion (C16:0, C18:0, C18:1n-9) of subcutaneous fat. 000061671 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000061671 590__ $$a0.288$$b2017 000061671 591__ $$aAGRONOMY$$b81 / 87 = 0.931$$c2017$$dQ4$$eT3 000061671 591__ $$aAGRICULTURE, DAIRY & ANIMAL SCIENCE$$b53 / 59 = 0.898$$c2017$$dQ4$$eT3 000061671 592__ $$a0.143$$b2017 000061671 593__ $$aAgronomy and Crop Science$$c2017$$dQ4 000061671 593__ $$aVeterinary (miscellaneous)$$c2017$$dQ4 000061671 593__ $$aHorticulture$$c2017$$dQ4 000061671 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000061671 700__ $$aDe Mercado, E. 000061671 700__ $$aGómez-Fernández, J. 000061671 700__ $$aTomás, C. 000061671 700__ $$aGuillamón, E. 000061671 700__ $$aVarela, A. 000061671 700__ $$aMuzquiz, M. 000061671 700__ $$aPedrosa, M.M. 000061671 700__ $$aLópez-Nuez, P. 000061671 700__ $$0(orcid)0000-0002-3005-2675$$aLatorre, M.A.$$uUniversidad de Zaragoza 000061671 7102_ $$12008$$2700$$aUniversidad de Zaragoza$$bDpto.
