INTRODUCTION One alternative to surgical castration of pigs is the immunocastration. Due to the Iberian pig long life cycle (approximately 16 months), the standard immunocastration protocol had to be modified.

OBJECTIVE Evaluate the influence of two immunocastration protocols: pre-pubertal (P) and pre-finishing (F) on the consumers’ acceptability of fresh loin from Iberian pigs.

In the conditions of the present experiment, no differences were found between the two immunocastration protocols for any of the sensory attributes of fresh loins evaluated by consumers.

The study is part of a national Spanish project entitled “Characterization and efficiency of agroecosystems for a greater sustainability of Iberian pig production”. RTA2013-00063-C03-00.
