        This experiment was conducted to investigate the effect of dietary supplementation of the Black Soldier Fly(BSF) larvae on growth performance, carcass rate, and fatty acid profile of chicken meat in broiler chicks. Four hundred eighty 1-d-old broilers(Ross 308) were distributed into 3 treatments with 4 pens at 30 birds per replicate. Treatments were corn-soybean meal based broiler diet (control) and the basal diet replaced with BSF at the level of 3 and 6% respectively. Viability was not different significantly. Body weight gain was higher in control than other treatments. Feed intake was not statistically different of treatments. Feed conversion ratio was lower in ontrol than other treatments. Relative weight of breast meat was significantly increased in all treated groups than in control. But, another relative weights of chicken meat cuts (thigh, wing, neck, back) were not significantly different among the groups. In conclusion, it could be suggested that dietary supplementation of Black Soldier Fly larvae could beneficially improved the performance on broiler

        This study examined the effects of different levels of evening primrose oil(EPO) on the accumulation of γ-fatty acids in broiler meat. Six hundred one-day-old male chicks (Ross strain) from commercial broilers were divided randomly into 6 groups × 4 repeat pens. The broilers were fed experimental diets containing 4.0% tallow(control), 0.5% EPO, 0.7% mixed oil(EPO 70 : soy bean oil 30), 1.5% EPO, 3.0% EPO or 4.0% EPO for 35 days. There was a significant difference in body weight gain between the control and treatment groups except for the 0.5% EPO group (p<0.05). There was a significant difference in the percentage of thigh and breast weight against the carcass weight between control and treatment groups except for the 0.5% EPO group in the thigh and 0.5% EPO and 4.0% EPO groups in the breast weight (p<0.05). The saturated fatty acid levels of the skin and breast muscle lipid of the broilers fed diets containing EPO were significantly lower than that of the control group (p<0.05), while the level of unsaturated fatty acid was significantly higher than that of the control group (p<0.05). The γ-fatty acid(GLA, gamma-linolenic acid, 18:3n-6) level was particularly higher in the chicken meat lipids from the broilers fed EPO than in the control group (p< 0.05). This shows that feeding EPO to chicks can produce novel functional broiler meat that is enriched in gamma-linolenic acid.

        The characteristics of the components related to the meat taste of the commercial broiler (CB) and the Korean native chicken (KNC) were compared. The breast meat from CB showed higher amounts of C16:1 and C18:2 but lower amounts of C16:0 and C22:6. The thigh meat from CB showed a higher amount of C18:1 but lower amounts of C16:0, C18:0, C20:4, and C22:6. The flavor- and taste-contributing amino acids, including aspartic acid, threonine, serine, glycine, alanine, tyrosine, lysine, histidine, and arginine, were significantly higher in the KNC breast meat, but the level of amino acids in the thigh meat were not different between the two breeds. The measurement of the volatile compounds revealed that CB contains much higher volatile compounds compared to KNC in their fresh breast and thigh meat. Both in the breast and thigh meat, however, the amount of flavor compounds increased significantly after cooking; as such, KNC turned out to have more flavor compounds than CB.
