Sustained Utilization of the Iberian Pig Breed

Foraging of Iberian fattening pigs grazing natural pasture in the dehesa

“…It is well known that Iberian pig montanera diet is based on acorns and grass (Aparicio Macarro, 1988;Lopez-Bote, 1998). This system is of great interest due to the differentiating characteristics it contributes both to the carcasses and the products derived from them (LopezBote, 1998).…”

Developmental competence of antral follicles and their oocytes after gonadotrophin treatment of sows with gene polymorphisms for leptin and melanocortin receptors (Iberian pig)

“…Ovulation rate after gonadotrophin stimulation was lower in the Iberian than in the LWxL sows; possible causes may be related to a lower intrinsic prolificacy of the Mediterranean genotype [20,27,28] but also, as supported by current and previous data [29], by a lower ovulatory efficiency of the follicles stimulated to grow by the exogenous gonadotrophins. Thereafter, most of the indexes of oocyte/embryo developmental competence (excepting fertilization rate) were higher in LWxL than in Iberian sows.…”
