Aims: to examine the addition of parijoto fruit extract encapsulated in feed on liver indicators and final body weight of broiler chickens raised at high density.

Study Design: A completely randomized design with 4 treatments and 5 replicates, resulting in 20 experimental units. The treatment applied includes T0=Chickens were raised at normal density (10 birds/m²) without parijoto fruit extract or extract encapsulated, T1= Chickens were raised at high density (16 birds/m²) without parijoto fruit extract or extract encapsulated, T2= Chickens were raised at high density (16 birds/m²) + 0.08% parijoto fruit extract, dan T3= chickens raised at high density (16 birds/m²) + 0.08% parijoto fruit extract encapsulated.

Place and Duration of Study: The research was conducted for 35 days in November-December 2024 at the teaching farm of the Faculty of Animal and Agricultural Sciences, Universitas Diponegoro Semarang.

Methodology: The experimental livestock used were 290 unsexed Ross broiler chickens aged 8 days with an average body weight of 196.01±1.12 g. Extraction was performed using sonication and maceration methods, and encapsulation using freeze dryer drying techniques. Treatment was administered from 8 to 35 days of age. Data collection was performed at 35 days of age, including relative daily weight, serum glutamic oxaloacetic transaminase (SGOT) and serum glutamic pyruvic transaminase (SGPT) levels, and final weight. The data were analyzed using analysis of variance at a significance level of 5%. If significant, Duncan's test was performed at a significance level of 5%.

Results: The addition of parijoto fruit extract or encapsulated extract to the feed had a significant effect (P<0.05) on the final weight of broiler chickens raised at high density, but had no significant effect (P>0.05) on the relative weight of the liver, serum SGOT and SGPT levels in chickens. The color of the liver showed that all treatments were brownish red.

Conclusion: The addition of 0.08% parijoto fruit extract encapsulated in the feed did not cause changes in color, liver weight, and liver function and increased the final weight of broiler chickens raised at high density.
