Resumen
The aim of the present work was to study whether weaned piglets with protein deficiency were able to select and prefer protein-related sources to overcome the deficiency. A total of 480 piglets were used in two experiments in which were fed with a high protein (HP, 204 g CP/kg) or low protein diet (LP, 142 g CP/kg) designed to contain an optimal o deficient CP content. In Experiment 1, the innate ability of piglets to prefer a protein (porcine digestible peptides 40 g/l) over a carbohydrate (sucrose 40g/l) solution was assessed by using a 3 min choice test. In Experiment 2, two flavors were conditioned with protein (animal plasma 60 g/l) or carbohydrate (maltodextrin 60 g/l) solutions in order to evaluate the learning effect on diet selection. Piglets preferred (P<0.001) sucrose over protein solution independently of the dietary CP content in Exp 1. However, piglets fed the LP diet showed a higher (P<0.01) intake of flavors conditioned with the protein solution than the carbohydrate solution (Exp 2). The results reveal the importance of the associative learning between the orosensorial properties and post-ingestive consequences of feedstuffs on feed selection patterns in pigs.
