Summary

- The fattening performance is very much influenced by the age of pigs and their compensatory growth; hence, pigs should be as old as possible (≥1 year) and adapted to grazing.
- Grass is necessary as a source of protein to compensate for the low protein levels in acorns.
- The food conversion rate is 10.5 kg of whole acorns of Q. i. rotundifolia to gain 1 kg, besides the contribution of grass; to establish the stocking rate, consider that an adult evergreen oak produces ≈11 kg of acorns/year).
- Iberian pigs peel acorns to avoid the high content of tannins in the shell. However, during peeling, approxi-mately 20% of the kernel can be wasted.

Summary translation

- El rendimiento durante el engorde está muy influenciado por la edad de los cerdos y su crecimiento compensatorio; por lo tanto, los cerdos deben tener la mayor edad posible (≥ 1 año) y estar adaptados al pastoreo.
- La hierba es necesaria como fuente de proteína, para compensar los bajos niveles de esta en las bellotas.
- El índice de conversión es de 10,5 kg de bellotas enteras de Q. i. rotundifolia para engordar 1 kg, además del aporte de hierba. Para establecer la carga ganadera, hay que considerar que una encina produce ≈11 kg de bellotas/ año.
- Los cerdos ibéricos pelan las bellotas para evitar el alto contenido de taninos de la cáscara. Sin embargo, durante el pelado, puede desperdiciarse aproximadamente el 20% de la pulpa.

EPrint Type:Practice tool
What problem does the tool address?:Montanera is a traditional feeding system where pigs forage for acorns. Iberian pigs foraging for acorns during their finishing phase has economically contributed to conserving the “dehesa”, a high nature value (HNV) farm-land based on agroforestry, currently consisting of more than four million hectares in the southwest of the Iberian Peninsula
What solution does the tool offer?:This natural resource is used to fatten pigs without any kind of compound or supplementary feed. During the last 2-3 months of fattening, pigs can gain more than 40 kg of body weight from grass and foraged acorns.
