This research aims to find out the appearance of free-range chicken fed with the addition og cocoa skin flour (Theobroma cacao L.)fermented in feeds.the design used is a Completely Randomixed Design with four treatmens and four tepetitions. The parameters observed and measured are the amount of feed consumption, body weight gain, and feed conversion. The data analysis used is the analysis of variance. The findings show that addition of famented cocoa skin flour in level 0%, 5%, 10% do  not significantly b influence (P0.05) on the feed consumption,body weight gain and the value of feed conversion in free-range chicken. The conlusion is the additional level of fermented cocoa skin flour to the level of 15% does not influence the appearance of free-range chicken

This study aims to determine the evaluation of the percentage of super native chicken carcasses by providing fermented corn straw. The research design used in the study was a Completely Randomized Design consisting of 5 treatments and 4 replications namely P0 (ration without treatment), P1 (ration containing 5% fermented corn straw), P2 (ration containing 10% fermented corn straw), P3 (ration ration containing 15% fermented corn straw) and P4 (ration containing 20% fermented corn straw). The data obtained were then analyzed using the Analysis of variance (ANOVA) and if the results were influential then proceed with the Duncan Distance test. The results showed that the treatment had no significant effect (P> 0.05) on the variables of life weight, carcass weight and percentage of carcass cut. The highest living weight was found in the P0 treatment (without using fermented corn straw) with the acquisition of an average value of 850.75 gr / head and produced the highest carcass weight of 197.25 gr. The highest percentage of carcass cuts was obtained at P3 treatment (15% fermented corn straw) with an average value of 23.88%.

The research objective was to evaluate the provision of skipjack tuna offal flour as a substitute for fish meal in quail rations. The research was conducted in August - October 2020 in Boidu Village, North Bulango District, Bone Bolango Regency, Gorontalo Province. The research design used was a completely randomized design (CRD). The use of skipjack offal flour in the ration had no significant effect (P 0.05) on ration consumption, ration conversion and body weight gain between treatment and control. The use of skipjack fish offal flour up to a content of 12% as a substitute for fish meal can be used in super native chicken rations.

Elephantgrass of the odot variety has a fast harvest period and is able to regrow quickly after defoliation. Bisi-16 maize variety has high production of biomass, crude protein and digestibility of feed. The experimental plots were arranged in a block design of latin square method at 4 treatments of planting density and 4 replications for each planting density. The planting density used for the elephantgrass variety of odot were high density (H), namely H1 = 25 cm x 25 cm (16 plants/m2 without inserting maize) as a control, and H2 = 25 cm x 25 cm (16 plants/m2) with a maize plant insert of 64 plants, Middle density (M) = 25 cm x 50 cm (8 plants/m2) with a maize plant insert of 80 plants, and Low density (L) = 50 cm x 50 cm (4 plants/m2) with a maize plant insert of 100 plants. The insertion of maize plants is 1 plant for every 10 cm of density. Both elephant grass and maize will be harvested at the age of 90 days after planting. Growth and biomass production of elephantgrass odot variety and bisi-16 maize variety increased with decreasing density and increasing insertion of maize plants from high, medium and low density. Double cropping between elephantgrass variety of Odot and maize variety of bisi-16 became an excellent blend of plants in producing forage beef cattle. Low density (50 cm x 50 cm) on elephantgrass variety of odot with insertion of 100 maize plants (1 cm/1 maize seedling) resulted in a high stocking rate as sustainable beef cattle feed.

Persentase karkas merupakan perbandingan antara bobot karkas dengan bobot hidup yang sering digunakan sebagai ukuran untuk menilai produksi ternak daging. Tujuan penelitian adalah untuk mengetahui persentase karkas ayam kampung super yang diberi tepung usus ayam sebagai substitusi tepung ikan dalam ransum. Penelitian menggunakan metode experimental dengan Rancangan Acak Lengkap (RAL) yang terdiri dari 5 perlakuan dan 4 ulangan. Seratus ekor ayam kampung super ditempatkan secara acak dalam 20 unit percobaan, masing-masing 5 ekor. Perlakuan yang diberikan adalah P0 (ransum dengan 10% tepung ikan, tanpa tepung usus ayam), P1 (ransum dengan 7,5% tepung ikan + 2,5% tepung usus ayam), P2 (ransum dengan 2,5% tepung ikan + 2,5% tepung usus ayam) P3 (ransum dengan 2,5% tepung ikan + 7,5% tepung usus ayam) P4 (ransum dengan 10% tepung usus ayam, tanpa tepung ikan). Variabel yang diamati adalah berat hidup, berat karkas, persentase karkas, berat dan persentase bagian-bagian karkas. Hasil penelitian menunjukkan bahwa perlakuan tidak berpengaruh nyata (P0,05) terhadap berat hidup, persentase karkas dan persentase bagian-bagian karkas, namun berpengaruh nyata (P0,05) meningkatkan berat karkas ayam kampung super. Disimpulkan bahwa tepung usus ayam dapat digunakan untuk substitusi tepung ikan 5-10% dalam ransum ayam kampung super dan tidak menurunkan bobot badan dan persentase karkas.Kata Kunci : Persentase Karkas Ayam Kampung Super, Tepung Usus Ayam, Tepung Ikan.
