| Popis: | The impact of dietary supplementation of a vegetable source of n-3 fat in the form of alpha-linolenic acid (ALA, 18:3n-3) on the accumulation of n-3 fatty acids in plasma chicken was investigated. Sixty unsexed one-day-old broiler chickens were randomly allocated to six diets (n=10 birds/diet) for 4 weeks. The birds were fed a proprietary starter commercial feed for the first two days after hatch. Six dietary treatments ranging in fat content from 5 to 10% were prepared by supplementing the basal diet with vegetable oils. The ALA levels varied from 1 to 8% energy (%en). The n-6 fatty acid linoleic acid (LA, 18:2n-6) level was limited to less than 5%en. Results showed that the metabolites of dietary ALA, EPA, DPA, and DHA in plasma tissues increased in a curvilinear manner as dietary ALA increased, achieving 3- to 13-fold compared to the levels in the control birds (P |
