|Título:||Analysis of a silvopastoral system with animals of the autochtonous swine breed Porco Celta in Galicia (NW Spain)|
|Resumo:||Pig traditional production systems in Galicia (NW Spain) are based on seasonal resources us like chestnut and pastures. The Breeders' Association of the autochthonous Celtic breed of pigs (ASOPORCEL) has developed a novel system within the traditional Galicia grazed forest areas in order to preserve landscape quality and biologic diversity, minimizing therefore the environmental impact of pig production. One of the main concerns of silvopastoral system implementation is the need of fencing. Fencing costs could be reduced if animals are rearing with infrastructures based on Pavlov animal condition reflex management in an extensive system. Therefore, cost reduction is obtained thanks to the clear reduction of personnel needs to feed animals, fencing costs and understorey clearance to reduce forest fires. In 2013 an experiment was carried out in Nebra (NW of Spain) in a young Pinus pinaster plantation. Pig stocking rate was around 3.85 pigs per ha (25 males and 25 females) in a total surface of 13 ha. Forest grazing program was initiated when animals were three months old in March 2013 and finished in December 2013. They were allowed access the whole plot. Concentrate was provided twice every day after sounding an alarm to attract pigs. All the animals adapted rapidly to the system. Two types o understory vegetation (Ulex and Pteridium) was sampled following a transect from close to far away feeding areas (three distances). Fern control was intense, being gorse less consumed. After nine months, average animal daily gain (ADG) obtained was 290 ± 4 gr. We can conclude that the used method is perfectly adaptable to the systems of exploitation suggested for the Celtic pig breed. This will be highly relevant to preserve this autochthonous breed and increase the number of extensive farms in the area while contributing to fix population dedicated to use silvopastoral systems.|
