    Abstract:
    The present study aimed to investigate the effects of replacing dietary soybean oil (SBO) with sacha inchi (Plukenetia volubilis L.) oil (SIO) supplemented or not with medicinal plant powder (MP, 60% cinnamon twig, and 40% star anise fruits) on broiler performance, carcass traits, and omega-3 polyunsaturated fatty acid (n-3 PUFA) content of breast meat. A total of 288 Ho × Luong Phuong broiler chickens (age and average body weight: 6 weeks old and 877 ± 13.4 g) were equally divided into three groups (6 replicates of 16 birds each), balanced by BW and sex. Each group was randomly allocated to one of three dietary treatments: a 2% SBO diet (CON), a 2% SIO diet (SI), and a diet supplemented with 2% SIO and 1% MP (SIM). The experiment lasted for 70 days. Broiler performance, carcass traits, and technological meat quality were not affected by the diets (P > 0.05). However, colored broiler chickens fed the SIM diet had increased empty gizzard percentage (P < 0.05) compared to those fed the CON diet. Especially, the n-3 PUFA content of breast meat from broiler chickens fed diets containing SIO was higher than those of birds fed CON diet (P < 0.01). A significant decrease in cholesterol content was observed (P < 0.01) in broilers fed SIM diet compared to those fed CON diet. In conclusion, replacing 2% SBO with 2% SIO and 1% MP supplementation in broiler diets increased n-3 PUFA content and decreased cholesterol content in breast meat, without negative effects on bird performance, carcass characteristics, and meat quality. Therefore, a combination of SIO and MP can be used as an effective strategy to ameliorate the meat quality of finishing broiler chickens by enhancing n-3 PUFA content and reducing the cholesterol content of breast meat.
