Abstract

Pigs with an initial average weight of 53 kg were allocated to three feeding treatments: T1) control diet containing vegetal and animal protein supplements, T2) diet of only vegetal protein supplements and T3) control diet restricted to 90 % of the amount offered to T1 plus free access to pasture. Productive performance parameters and carcass traits at slaughter were determined. Intramuscular fat content of Longissimus dorsi, lipid profile of the subcutaneous and intramuscular fat, content of iron, zinc, magnesium, sodium and vitamin E were analyzed. The melting point of the back fat was also analyzed as an indicator of the technological aptitude for the manufacturing of fermented products. Fat from each treatment was used to manufacture salamis that were sensory evaluated. Carcass quality parameters did not show statistically significant differences. Access to pasture showed an increase in linolenic acid content and a better relationship n6/n3 in the subcutaneous fat. There were no significant differences in the fat melting point. Salami samples were different with a confidence level of 95 % for texture attributes and purchase intent.
