The purpose of this research was to examine the carcass quality and meat quality of native chicken fed dried tomato meal in diet. The study was conducted by using 200 heads of native chickens 10 days. The birds were divided into five experimental diets and each was divided into four replicate groups of ten birds per replicate. The based diet was formulated to contain 42% corn, rice bran 9%, fish meal 10%, fish oil 5%, soybean meal 9% and commercial diets 25%. Tomato meal was included in five experimental diets at levels of 0, 3, 6, 9, 12% to substitute based diets. The treatments were PO = 100% based diet (BD) + 0% tomato meal (TM); P1 = 97% BD+ 3% TM; P2 = 94% BD + 6% TM;P3 = 91% BD + 9% TM; P4 = 88% BD + 12% TM. Chemical composition of tomato meal was: 20.73% crude protein, 1.53% fat, 30.94%crude fiber, 0.98% Ca, 1.20% P and 2,416 kcal/kg of Gross Energy (GE). Results showedthat feeding tomato meal at an inclusion rate of 12% increased slaughter weight, carcass, breast meat, wings, drumstick and thigh, and decreased abdominal fat and blood cholesterol. Moreover, there were no significant difference in giblet (liver, heart and gizzard) between treatments. Meat water and meat crude protein were significantly increased. Meat crude fat and meat cholesterol were significantly decreased. In conclusion, tomato meal can be used as an alternative feedstuff in kampong chicken diets at inclusion levels up to 12% without negative effects on carcass quality and meat quality.

ABSTRAKPenelitian ini bertujuan untuk mengetahui pengaruh penambahan ampas kelapa pada pakan ruminansia terhadap reduksi metan secara in vitro. Penelitian ini menggunakan cairan rumen dengan substrat hijauan dan konsentrat dengan perbandingan 60:40. Percobaan ini terdiri dari lima macam perlakuan ampas kelapa yakni: R1: tanpa penambahan ampas kelapa; R2: substrat pakan dengan penambahan ampas kelapa 5%; R3: substrat pakan dengan penambahan ampas kelapa 10%; R4: Substrat pakan dengan penambahan ampas kelapa 15% dan R5 substrat pakan dengan penambahan ampas kelapa 20%. Setiap perlakuan dilakukan empat kali ulangan. Fermentasi dilakukan menggunakan Hohenheim Gas Test (HGT) pada suhu 39 o C selama 72 jam. Pada akhir fermentasi dilakukan pengukuran gas metan, parameter fermentasi, aktivitas mikrobia, kecernaan nutrient dan profil asam lemak cairan rumen. Data dianalisa menggunakan rancangan acak lengkap dan dilanjutkan dengan Duncan test (DMRT) untuk perbedaan rataan. Hasil penelitian menunjukan bahwa produksi metan mengalami penurunan sekitar 13,74%-17,39 % ketika pakan diberi ampas kelapa sebanyak 15-20%. Dari hasil penelitian disimpulkan bahwa pemberian ampas kelapa 15-20% dalam pakan ruminansia dapat mereduksi gas metan serta tidak mengganggu aktivitas mikrobia pada fermentasi cairan rumen secara in vitro. Supplementasi ampas kelapa tersebut dapat dijadikan acuan dalam mendesain pakan penghambat metanogenik.Kata kunci : metan, ampas kelapa, fermentasi rumen, gas tes, parameter fermentasi ABSTRACTThis experiment was conducted to determine the effect of the adding of coconut pulp in ruminant feed on methane reduction in vitro. Rumen fluid and substrate of forage and concentrate in ratio 60:40 were in this study. This experiment consisted of five treatments of coconut pulp as followed: R1: feed substrates without the coconut pulp; R2: substrate feed with coconut pulp 5%; R3: substrate feed with coconut pulp 10%; R4: Substrate feed with coconut pulp 15% and R5: substrate feed with coconut pulp 20%. Each treatment was conducted to four replications. Fermentation was done using the Hohenheim Gas Test (HGT) incubated at 39 o C for 72 hours. At the end of fermentation was determined production of methane, parameters of fermentation, microbial activity, feed digestibility and fatty acids profile of the ruminal fluid. Data obtained were analyzed by using analysis of variance using completely randomized design. The differences of mean values were analyzed by Duncan multiple range test (DMRT). The results showed that methane production has decreased about 13.74%-17.39% when the feed was given coconut dregs 15-20%. Based on the results of the study was concluded that the supplementation of coconut pulp up to 15-20% of 100% dry matter can be used as a substrate of ruminant feed, because it can reduce methane and does not interfere the microbial activity in the fermentation of rumen fluid through in vitro. The supplementation of coconut pulp can be a referencein 202 J.Indonesian Trop.Anim.Agric. 42(3):202-209, September 2017 ...

SENSORICAL QUALITY AND PHYSICAL PROPERTIES OF CHICKEN NUGGETS WHICH IS ADDED PURPLE ROAD UBI FLOUR (Ipomoea batatas L). This study aims to determine the benefits of using purple sweet potato flour (Ipomoea batatas L) on the sensory quality and physical properties of chicken nuggets. The research was carried out in 3 stages, namely (1) making purple sweet potato flour, (2) making chicken nugets with the addition of purple sweet potato flour, (3) testing chicken nuggets including sensory quality testing using 35 untrained panelists to measure the level of acceptance of aroma, color, texture and taste, physical properties test to determine water binding power and cooking losses. This research was conducted experimentally using a completely randomized design with 4 additional treatments of purple sweet potato flour, namely P1 = 10 g, P2 = 20 g, P3 = 30 g and P4 = 40 g, each treatment was repeated as many as 35 (panelists) for the test. sensory quality and 5 replications for physical characteristics test. Data from the observation of sensory quality test, physical properties were tabulated and analyzed by analysis of variance (Ansira) and if there were significant differences between treatments, it was continued with Duncan's multiple test (DMRT). The results of the research with analysis of variance showed that the addition of 10, 20, 30 and 40 grams of purple sweet potato had a very significant effect (P <0.01) on color, texture, water-binding capacity and cooking loss but had no significant effect. (P> 0.05) on aroma and taste. The results of Duncan's multiple further test showed that the P4 treatment of 40 g of purple sweet potato gave the best results on color, texture, water binding power and cooking loss. Based on the results and discussion, it can be concluded that the addition of 40 g of purple sweet potato flour in the manufacture of chicken nuggets provides good sensory quality and physical properties.Keywords: Chicken nuggets, purple sweet potato flour, sensory quality, physical properties
