The present study was conducted to evaluate the effect of Sauropus androgynus (katuk) leaves extract (SAE) and lemuru fish oil (LO) on fat deposition and fatty acid composition of meat in broiler chickens. One hundred and fifty six broiler chickens were distributed to 13 treatment groups with 3 cages in each treatment group as replicate. Completely randomized design was used in this study. The thirteen groups were subsequent of broiler chickens that were fed diet containing commercial feed supplement as a control (P1), 10 g/kg SAE and 1% LO (P2); 10 g/kg SAE and 1% LO plus 60 mg vitamin E (P3), 10 g/kg SAE and 2% LO (P4), 10 g/kg SAE and 2% LO plus 60 mg vitamin E (P5), 10 g/kg SAE and 3% LO (P6), 10 g/kg SAE and 3% LO plus 60 mg vitamin E (P7), 18 g/kg SAE and 1% LO (P8), 18 g/kg SAE and 1% LO plus 60 mg vitamin E (P9), 18 g/kg SAE and 2% LO (P10), were 18 g/kg SAE and 2% LO plus 60 mg vitamin E (P11), 18 g/kg SAE and 3% LO (P12), and 18 g/kg SAE and 3% LO plus 60 mg vitamin E (P13). The data were analyzed by analysis of variance and if it were significant, it were then determined by Duncan's Multiple Range test. The present results showed that supplementation of SAE and LO significantly affected (P<0.05) fat deposition in abdomen and leg, but it had no effect on neck fat deposition and Fatty Liver Score. Supplementation of SAE and LO had significantly reduced (P<0.05) cholesterol content and thiobarbituric acid (TBA) in leg meat, but it significantly increased (P<0.05) vitamin A and vitamin E and it had no effect on fat in leg meat. Supplementation of SAE and LO proved to change fatty acid composition in leg meat. The treatment highly significant increased ecosapentaenoic acid (EPA) and docosahexaenoic acid DHA (P<0.01), arachidonic acid and stearic acid (P<0.05), but it significantly reduced linolenic acid (P<0.05). In conclusion, the supplementation of SAE and LO reduced fat deposition in abdomen and leg, the content of cholesterol in meat, and it enriched EPA and DHA of meat.

ABSTRAKPenelitian untuk mengetahui potensi tepung daun Indigofera sebagai campuran pakan puyuh dan pengaruhnya terhadap produksi dan kualitas/warna kuning telur (The Roche Yolk Colur Fan Score) pada Coturnix coturnix japonica. Dua ratus puyuh betina umur 5 minggu dikandangkan menjadi 40 petak masing masing petak 5 ekor, dikelompokkan menjadi 5 kelompok perlakuan masing masing perlakuan ada 8 ulangan. Susunan ransum untuk puyuh (sudah produksi) mengandung protein kasar 20% dan energi 2900 kkal/g (NRC, 1994).Perlakuannya adalah penggunan 0%;2,5%;5%;7,5% dan 10% tepung daun Indigofera . Variabel yang diamati ialah berat awal, konsumsi pakan,konversi pakan, bertelur pertama (dewasa kelamin), produksi telur, berat telur dan skor warna Yolk Data dianalisis dengan anova berdasarkan RAL (CRD). Bila ada perbedaan dilakukan uji LSD. Hasil penelitian menunjukkan tidak ada perbedaan konsumsi pakan, bertelur pertama (dewasa kelamin), produksi telur dan berat telur,akan tetapi ada perbedaan pada skor warna Yolk (P<0,01). Penggunaan tepung daun Indigofera memperbaiki/menaikkan skor warna Yolk.Kata Kunci: indigofera, puyuh, produksi telur, warna yolk

The objective of this study was to evaluate the performance of Arab descendants with Arras Chicken (Ayam Ketarras) age 2-12 weeks. This research has been conducted for 6 months, starting from 25 June to 25 December 2016 in CZAL. The treatments were chicken type with P0 = Ketarras chicken and P1 = Arabian chicken. This study used t test analysis with 2 treatments 15 replications. Each replication used 2 chickens, so each type of chicken required 30 tails. The variables observed were, consumption of ration, growth, and conversion of rations. T test results showed that the cumulative feed intake during the study for both types of chicken had no significant effect (t t table). The consumption of cumulative chicken ration at age 2-7 and 2-8 is higher than Ketarras chicken. Cumulative feed consumption at the age of 2-12 weeks of chicken feed consumption of Arab chicken (3474.70 g) was not significant compared to Ketarras chickens (3453.30 g). The mean weight gain during the study of the two different types of chickens was not significant (t count t table) except at age 2-3, and 2-8 weeks. However, weight gain during the age of 2-12 weeks at the Arab chicken was significantly higher than Ketarras chicken, that chicken Arab (718.83 g) and Ketarras chicken (645.07 g). Cumulative feed conversion both types of chicken had no significant effect (t
