Two groups of pigs were reared under two different farming systems, indoor (pigsty breeding) and outdoor (woodland pasture). They were slaughtered when the live weight reached 140 kg. Outdoor group reached the final weight 30 days later than the indoor group, due to a slower growth rate. Measurements obtained at the slaughtering showed a heavier gastroenteric apparatus in the pigs of the outdoor group (7.52 vs 5.17 kg), without influences on the slaughter yield. There were no significant differences among anatomical speciments, except for shins that were heavier in the pigs of the outdoor group (1.08 vs 0.92% of carcass weight). Outdoor pigs showed longer and thinner rearfeet. Regarding the composition of the carcass, the outdoor group showed a bigger amount of fat (9.35% of sample cut) than the indoor group (4.70% of sample cut).

Abstract
Two groups of pigs were reared under two different farming systems, indoor (pigsty breeding) and outdoor (woodland pasture). They were slaughtered when the live weight reached 140 kg. Outdoor group reached the final weight 30 days later than the indoor group, due to a slower growth rate. Measurements obtained at the slaughtering showed a heavier gastroenteric apparatus in the pigs of the outdoor group (7.52 vs 5.17 kg), without influences on the slaughter yield. There were no significant differences among anatomical speciments, except for shins that were heavier in the pigs of the outdoor group (1.08 vs 0.92% of carcass weight). Outdoor pigs showed longer and thinner rearfeet. Regarding the composition of the carcass, the outdoor group showed a bigger amount of fat (9.35% of sample cut) than the indoor group (4.70% of sample cut).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
