Abstract

The purpose of this study was to determine the effect of pressing fish waste flour in the Christmas II market on protein, fat, and energy content. The research method used in this study was a completely randomized design (CRD), which consisted of 4 treatments and 5 replications. The following were performed: P0: Fish waste flour from poultry; P1: Fish waste flour is dried under the sun; P2: Fish waste flour is pressed and dried in the sun; P3: Fish waste flour is pressed in the oven with a temperature of 400C. The research parameters are the content of crude protein, crude fat, and gross energy. The results of this study showed that the effect of pressing fish waste flour on the II Natal market showed that the highest crude protein content was in the P0 treatment (fish waste flour from poultry); Crude fat and gross energy were highest in treatment P1 (fish waste flour dried under the sun). The results of analysis of crude protein in samples of fish meal treatment, it was found that the one with the highest crude protein content was treatment P0 (fish waste flour from poultry) which was 53.07% then treatment P2 (pressed fish waste flour dried under the sun) with an average 43.31% and P3 (pressed fish waste flour in the oven with a temperature of 400C) of 42.66% and the one with the lowest crude protein content was 41.81%, namely treatment P1 (waste fish flour dried under the sun). The lowest percentage of crude fat content was found in treatment P0 (fish waste flour from poultry) which was 0.16% and the highest was in treatment P1 (dried fish waste flour in the sun) which was 2.93% and the highest gross energy was 2,852.46 cal /100g in treatment P1 (fish waste flour drying under the sun), and the lowest was 2,252.63 cal/100g in treatment P0 (fish waste flour from poultry). The results of the analysis of variance for the content of crude protein, crude fat, and gross energy content showed very significant differences (P<0.01) in this study. The results of the test of variance which were very significantly different were then tested further using the honest significant difference (BNJ) follow-up test according to the respective coefficient of diversity.

Abstract

This study aims to evaluate the nutritional quality and probiotic potential of Black Soldier Fly (BSF) maggot substrate waste or kasgot as an alternative feed ingredient in broilers. The hypothesis of this study is that the addition of kasgot in the ration can increase the nutritional content as well as provide a probiotic effect that supports the health of the digestive tract of broiler chickens. The research was conducted using an experimental method with a Complete Random Design (RAL) consisting of 4 treatments and 5 replicates. The treatments provided include: P0 (control commercial feed), P1 (75% commercial feed + 25% cash), P2 (50% commercial feed + 50% cash), P3 (25% commercial feed + 75% cash), and P4 (100% cash). The parameters observed included the content of crude protein, crude fat, crude fiber, gross energy, and the potential of probiotic microbes in the cass. The results showed that P1 treatment provided the most optimal nutrient composition, with gross energy of 3078.34 cal/100g, crude protein 20.10%, and crude fat 5.35%. Giving kasgot at the level of 25% is considered more effective than higher levels because it maintains the nutritional balance of the ration and supports the function of natural probiotics for broilers. In conclusion, kasgot has the potential to be an alternative feed ingredient and a source of probiotics that can be used in the formulation of broiler chicken rations at a substitution level of 25%.

Abstract

Peternakan ayam buras merupakan salah satu subsektor peternakan yang berperan penting dalam mendukung ketahanan pangan, penyediaan sumber protein hewani, serta peningkatan pendapatan masyarakat pedesaan. Namun, produktivitas usaha ayam buras masih menghadapi berbagai kendala, terutama tingginya biaya pakan yang mencapai lebih dari 60% dari total biaya produksi. Ketergantungan terhadap pakan komersial dengan harga yang fluktuatif menyebabkan efisiensi usaha peternak menjadi rendah. Di sisi lain, berbagai bahan baku lokal dan hasil samping pertanian yang tersedia di wilayah pedesaan belum dimanfaatkan secara optimal sebagai bahan penyusun pakan karena masih terbatasnya pengetahuan dan keterampilan peternak dalam formulasi ransum dan teknologi fermentasi. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan kapasitas peternak ayam buras melalui penerapan teknologi pakan fermentasi berbasis bahan baku lokal sebagai upaya meningkatkan produktivitas ternak dan efisiensi usaha. Metode pelaksanaan dilakukan secara partisipatif melalui enam tahapan, yaitu persiapan, sosialisasi, penyuluhan, pelatihan praktik (learning by doing), demonstrasi penerapan pakan fermentasi pada ternak, pendampingan berkala, serta evaluasi kegiatan. Program menitikberatkan pada transfer pengetahuan dan keterampilan sehingga peternak mampu memproduksi pakan fermentasi secara mandiri sesuai kebutuhan usaha. Hasil kegiatan menunjukkan adanya peningkatan pengetahuan dan keterampilan peternak mengenai teknologi fermentasi pakan, meningkatnya kemampuan peserta dalam menyusun dan memproduksi pakan fermentasi secara mandiri, serta meningkatnya pemanfaatan bahan baku lokal sebagai alternatif pakan. Penerapan pakan fermentasi berbasis dedak padi, jagung, dan bahan pakan lokal lainnya menghasilkan tingkat konsumsi pakan yang baik serta berkontribusi terhadap penurunan biaya pakan sehingga efisiensi usaha peternakan meningkat. Selain memberikan manfaat ekonomi, program ini juga mendorong pemanfaatan sumber daya lokal secara berkelanjutan dan mengurangi ketergantungan terhadap pakan komersial. Dengan demikian, penerapan teknologi fermentasi pakan merupakan salah satu strategi pemberdayaan peternak ayam buras yang efektif dalam meningkatkan produktivitas, efisiensi biaya produksi, serta kemandirian usaha peternakan rakyat menuju sistem peternakan yang berkelanjutan.

Abstract

This study aimed to analyze the egg productivity of native chickens fed fermented feed using different bioactivators. The primary issue underlying this study was the relatively low egg productivity of indigenous chickens in Indonesia, which ranges from 60 to 120 eggs per hen per year, as well as the high cost of conventional feed, accounting for approximately 60–70% of total production costs. As an alternative solution, a bioconversion technology in the form of feed fermentation was applied to break down the crude fiber bonds in rice bran and corn, improve feed quality and crude protein content, reduce antinutritional compounds, and enhance nutrient digestibility in the digestive tract of chickens. The experiment was conducted using a field laboratory approach based on a non-factorial Completely Randomized Design (CRD) consisting of four dietary treatments with five replications. Each experimental unit contained three 7-month-old native laying hens, resulting in a total of 60 experimental birds. The basal diet consisted of corn (51%), rice bran (30%), soybean meal (10%), fish meal (3%), cooking oil (2%), limestone (1%), and mineral mix (3%). The diet was mixed with selected bioactivator solutions and palm sugar, followed by anaerobic incubation for an optimum fermentation period of 4–7 days. The observed parameters included daily feed intake, daily egg production expressed as Hen Day Production (HDP), average egg weight, and feed efficiency measured by Feed Conversion Ratio (FCR). The collected data were analyzed using Analysis of Variance (ANOVA) to determine the significance of treatment effects. The results demonstrated that fermented feed supplemented with the Starbio bioactivator (P3) produced the most favorable performance, resulting in the highest HDP (54.80%), the greatest average egg weight (46.50 g), and the lowest FCR (3.13), indicating the highest feed efficiency. These findings are expected to provide a scientific basis for smallholder poultry farmers in selecting appropriate commercial bioactivators for producing high-quality fermented feed, thereby reducing feed production costs and supporting the sustainable development of native chicken farming.
