The aim of the trial was to evaluate the effects of the dietary addition of a 3% sunflower oil containing high-oleic and low-linoleic acid levels (HOSO), supplemented or not with vitamin E, on heavy pig production parameters (growth, meat quality and fatty acid composition of ham subcutaneous fat). 64 Duroc x Large White pigs were allotted to four group (Control, Control plus vitamin E, 3% HOSO and 3% HOSO plus vitamin E). Regardless of vitamin E supplementation, our results indicate that a 3% addition of HOSO has no effect both on growth parameters and carcass and fresh meat quality. HOSO dietary addition resulted in a higher (P<0.001) level of oleic acid and in lower levels of palmitic and stearic acids in the subcutaneous fat. Furthermore, fat deriving from pigs on HOSO diets showed a higher (P<0.001) iodine value. Nevertheless, linoleic acid level and iodine value did not exceed the maximum allowed for long-curing PDO hams.

Abstract
The aim of the trial was to evaluate the effects of the dietary addition of a 3% sunflower oil containing high-oleic and low-linoleic acid levels (HOSO), supplemented or not with vitamin E, on heavy pig production parameters (growth, meat quality and fatty acid composition of ham subcutaneous fat). 64 Duroc x Large White pigs were allotted to four group (Control, Control plus vitamin E, 3% HOSO and 3% HOSO plus vitamin E). Regardless of vitamin E supplementation, our results indicate that a 3% addition of HOSO has no effect both on growth parameters and carcass and fresh meat quality. HOSO dietary addition resulted in a higher (P<0.001) level of oleic acid and in lower levels of palmitic and stearic acids in the subcutaneous fat. Furthermore, fat deriving from pigs on HOSO diets showed a higher (P<0.001) iodine value. Nevertheless, linoleic acid level and iodine value did not exceed the maximum allowed for long-curing PDO hams.File | Dimensione | Formato | |
