This research was aimed to determine the effects of perilla seeds (Perilla frutescens L.) levels in the diet on the percentage of carcass and non carcass, chemical quality and levels α-linolenic acid (ALA) of meat ducks. The research design was one way Completely Randomized Design with 3 treatments, 6 replications and each replication consisted of 6 head ducks. The treatment included; P0 : (100% basal feed); P1 : (97.5% basal feed + 2.5% perilla seed) and P2 : (95% basal feed + 5% perilla seed). The carcassing process was carried out when the age of the local ducks reaches eight weeks by slaughtering 2 head ducks for each replication. Materials used 36 samples of breast duck meat were observed. The experiment was conducted for 60 days. The data were analyzed with one way analysis of variance (ANOVA). If there was significant differences among treatments, Duncan’s multiple range test (DMRT) were applied. The result shows the carcass weight and non carcass percentage were not significant (P>0.05), but breast percentage and liver percentage were significant (P<0.05). The perilla seed supplementation had significant effect (P<0.05) on increased levels of protein, cholesterol and α-linolenic acid and also had a very significant effect (P<0.01) on decrease level of meat fats. The conclusion of this research is the enriched of perilla seed at the level of 5% in basal feed does not increased the carcass weight, percentage carcass and non carcass, but increased percentage breast and liver. The quality of protein and omega-3 fatty acids and reduce fat levels, but had not been able to reduce cholesterol levels in local duck meat. [ABSTRACT FROM AUTHOR]
