Fatty acids composition of poultry meat from indoor and outdoor raising

The research was carried out on chickens of Ross 208 provenience, which were divided into two groups. Chickens reared outdoor had statistically significantly higher portion of alpha-linolenic acid (P<0.05), linoleic and arachidonic acid, as well as higher total of PUFA n-6 acids (P<0.01) than chickens that were kept indoor. However, these chickens had higher portion of myristic and palmitic acid (P<0.01), as well as DHA (P<0.001) in the lipids of breast muscles. There was also higher content of myristic and linoleic acids (P<0.01) determined in the lipids of thigh muscles of chickens reared indoor, while chickens kept outdoor had higher content of EPA (P<0.01), palmitic, stearic and arachidonic acids (P<0.001). Chickens of the 2nd group exhibited more favorable ratio of PUFA n-6 / PUFA n-3 in the lipids of breast muscles. The same ratio for the lipids of thigh muscles was better in the 1st group.
