This study was to determine the use of fish oil microcapsules in rations on the percentage of abdominal fat and cholesterol levels in broiler meat. The study used 100 DOC broilers with CP 707 code. The rations used consisted of rice bran, milled corn, soybean meal, fish meal, coconut oil, fish oil microcapsules (MMI), topmix and dolomite containing 22% protein with an energy content of 3000 Kcal / kg. The research method used Completely Randomized Design (CRD) with 4 treatments and 5 replications. The first treatment (R1) is containing 0.8% fish oil (control), the second treatment (R2) contains MMI 2%, the third treatment (R3) containing MMI 4%, and the fourth treatment (R4) containing 6% MMI. The parameters measured were the percentage of abdominal fat (%) and meat cholesterol (mg / 100g). The results of the analysis of variance that showed not significant effect for abdominal fat percentage until the use of MMI is 6%. As for meat cholesterol content, R2 and R3 treatment showed a very significant different effect (P<0.01) lower than R1 treatment (control), and R4 treatment showed significant differences (P<0.05) lower than R1 treatment (control), while between treatments R2, R3 and R4 showed no significant effect (P>0.05). Based on the results of this study, it can be concluded that the use of MMI (fish oil microcapsules) at a level of 2% in broiler rations can have a significantly different effect on meat cholesterol content than controls, whereas for abdominal fat percentage the effect is not significant until the use of MMI is 6%.

Penelitian broiler dengan pemberian tanaman obat sebagai feed additive dalam ransum berupa tepung daun salam, daun pepaya, daun jambu biji dan tepung daun miana untuk melihat pengaruhnya terhadap performa broiler. Penelitian dilakukan selama 2 bulan yang dilakukan di Laboratorium Nutrisi dan Pakan Ternak dan di kandang broiler Laboratorium Produksi Ternak. Broiler yang digunakan  100 ekor umur satu hari. Pakan yang diberikan ransum adukan yang terdiri dari jagung, bungkil kedele, tepung ikan, tepung mie, minyak, top mix. Perlakuan yang diberikan adalah daun salam (Eugenia polyantha Wight), daun pepaya (Carica papaya Linn), daun jambu biji (Psidium Guava L)  dan  daun miana (Coleus scutellarioides) yang dijadikan tepung. Rancangan yang digunakan adalah  RAL, dengan  5 perlakuan dan 4 ulangan, yaitu ransum adukan 100% sebagai kontrol (A), penambahan 0,5% tepung daun salam pada ransum adukan (B), penambahan 0,5% tepung daun pepaya pada ransum adukan (C), penambahan 0,5% tepung daun jambu biji pada ransum adukan (D) dan penambahan 0,5% tepung daun miana pada ransum adukan (E). Parameter penelitian adalah menghitung konsumsi ransum, pertambahan bobot badan dan konversi ransum.  Hasil penelitian didapatkan bahwa tanaman obat sebagai feed additive dalam ransum memberikan pengaruh yang  tidak berbeda nyata (P>0,05) terhadap konsumsi ransum, pertambahan bobot badan dan konversi ransum.

Increased bacterial resistance to antibiotics provides a great opportunity to obtain antibacterial compounds by utilizing bioactive compounds from biological natural wealth. In Indonesia there are many known medicinal plants. Miana plants (Coleus atropurpureus, L) are one of the potential medicinal plants in Indonesia. This plant is widely used as medicine. This study aims to determine the effect of adding miana leaf flour to the ration on body weight gain, feed consumption, feed conversion and carcass percentage. This study used a completely randomized design with 5 treatments and 4 replications. The treatment was A = control, B = 1% Miana leaf flour / kg ration. C = 2% leaf flour miana / kg ration, D = 3% miana leaf flour / kg ration E = 4% miana leaf flour / kg ration. What was observed were performance and carcass including feed consumption, feed conversion, body weight gain, carcass percentage. The results of this study showed that the addition of miana leaf flour in the ration had no significant effect (P> 0.05) on body weight gain, feed conversion, feed consumption and carcass percentage. Giving miana leaf flour in the ration can be  tolerated up to 4% in broiler rations.

Poultry products from such as broiler chicken usually contain residues because in the maintenance of chicken used medicinal ingredients, both to prevent disease and increase body weight. This study was aimed to determine the ability of pegagan plan (Centella asiatica) as natural feed additive to stimulate the body weight of chicken. The experiment was run in completely randomized design which consist of 4 feed treatments and 5 replications. Level used of A = without pegagan powder; B = 1.5% pegagan powder; C = 3% pegagan powder dan D = 4.5% pegagan powder. The result shown that body weight was significantly different (P < 0.05) but not for HI ND was no significantly different (P > 0.05). The higher of body weight of chicken shown in D parameter (level 4.5% pegagan powder) was 944.0 g. Pegagan influences a vasodilation to increase blood flow of chicken which has an impact on increasing body metabolism, so that it becomes an acceleration of body weight gain in broiler chickens.

This study was conducted to evaluate the carcass percentage and abdominal fat of broiler chicken with added feed additive pegagan (Centella aciatica) powder on ration. This experiment was done at poultry farm and laboratory of Animal Husbandry Programme, Payakumbuh Agricultural Polytechnic from July to December 2018. The experiment was run in completely randomized design which consist of 4 feed treatments and 5 replications. Level used of A = without pegagan powder; B = 1.5% pegagan powder; C = 3% pegagan powder dan D = 4.5% pegagan powder. The collected data was analyzed with ANOVA and Duncan Range test would use for post hoc multiple comparison. The result shown that body weight was significantly different (P < 0.05), carcass percentage and abdominal fat were no significantly different (P > 0.05). Body weight of broiler chicken was higher on level D = 4.5% pegagan powder. The additive compounds in pegagan as feed additive stimulated immunity of broiler chicken until provide better body weight but unaffected on carcass percentage and abdominal fat.
