Abstract
The aim of this study was to evaluate the influence of diet supplemented with linseed rich additive under commercial name Vitalan (Vitalac, France) on omega-fatty acids content in pig meat. The main ingredient in Vitalan is extruded linseed, which made the test diet rich in omega-3 acids. Fourteen pigs were divided in to the control and the experimental group and grown to cca 110 kg of average live weight. The experimental group was fed a standard diet enriched with 2.5% of Vitalan. After the end of the feeding period, the meat samples from both groups were analyzed for omega-3 and omega-6 fatty acids content in raw and oven- roasted meat. The ratio between omega-6 and omega-3 acids was established. Additionally, other parameters, such as weight gain, feed consumption and feed conversion ratio of pigs were monitored during the study. The experimental group fed linseed enriched diet showed higher omega-3 acids content in meat (>7 mg/100g), had reduced ratio of omega-6 and omega-3 acids in meat (< 3), thus making it better for human consumption from the health perspective. Also, the treatment with enriched diet caused faster weight gain vs control diet (0.623 vs 0.592 kg/day), lower feed consumption (272 vs 274 kg/kg) and better feed conversion (3,36 vs 3,56 kg/kg). The conclusion was that the diet enriched with extruded linseed had a beneficial effect on the majority of parameters monitored in the study.
