Abstract

Indonesia's livestock sector is currently developing very quickly due to public awareness of the nutritional value of animals, one of which is from super free-range chickens. Super free-range chickens or superior broiler chickens are the result of a cross between free-range chickens and egg-laying breed chickens. The purpose of the study was to find out the effect of giving fermented Japanese papaya leaf flour on the growth of super free-range chickens aged 3 - 10 weeks. Super free-range chickens in their maintenance need quality feed to fulfill their nutrition. However, rations are the largest cost component, which is 60-80% of the total production cost of poultry, so there needs to be an effort to reduce the conversion value by using other feed alternatives, but without reducing the productivity of the livestock. Kersen leaves contain nutrients that also have anti-bacterial properties and contain phytochemicals including flavonoids, tannins, triterpenes, and saponins that show antioxidant activity The nutritional content of kersen leaf flour is 5.02% water, 6.39% ash, 11.31% crude protein, 14.85% crude fiber, 7.53% fat, 69.75% carbohydrates and 3988 kcal/kg of metabolic energy. Kersen leaves can be used as feed ingredients in rations by fermenting to reduce the crude fiber (14.85%) it contains. The design used in this study is a Complete Random Design (RAL) with 5 treatments and 3 replicates. P0 = A ration without containing fermented kersen leaf flour. P1 = The ration contains 3% fermented kersen leaf flour. P2= The ration contains 6% fermented kersen leaf flour. P3 = The ration contains 9% fermented Japanese kersen leaf flour. P4 = The ration contains 12% fermented kersen leaf flour. The indicators observed were initial body weight, weight gain, final body weight, ration consumption and Feed Conversion Ratio (FCR). The results of the study showed that the growth of super free-range chickens fed a ration of fermented kersen leaf flour showed different results (P>0.05) on initial body weight, weight gain, final body weight and FCR, while in ration consumption there was a real effect (P<0.05). Based on the results of this study, in the P1 treatment, the administration of fermented cool leaf flour gave the best results by giving 3%.

Abstract

Success in developing a livestock business is greatly influenced by three key elements, namely the availability, quality, and continuity of animal feed supply. In general, ruminant livestock feed consists of green fodder and concentrates. Concentrates are generally formulated from waste and by-products of the agricultural and agro- industrial sectors. The supply of green fodder, especially grass, often fluctuates in terms of both quantity and quality, especially during the dry season, due to limited water and decreased plant growth rates. This condition requires alternative green fodder that is adaptive to marginal environments, has high biomass productivity, and adequate nutritional value. One of the plants with great potential is sorghum (Sorghum bicolor L. Moench), Sorghum (Sorghum bicolor (L.) Moench) is a cereal crop with great potential to be developed as green fodder. In order to meet nutrient needs, the appropriate fertilization is by providing solid organic fertilizer from goat manure. This study aims to determine the nutritional content of Sorghum (Sorghum bicolor L. Moench) green fodder given solid organic fertilizer from goat manure. This research was conducted from September to December 2025 at Jln. Sedap Malam, Banjar Kebon Kori Kelod, Gang Melati No. 15, East Denpasar. This research used a Randomized Block Design (RBD) with 5 treatments and 3 replications. The treatment used was with different fertilization doses P0 = Sorghum plants without giving solid organic fertilizer goat manure (Control), P1 = Sorghum plants with a fertilization dose of solid organic fertilizer goat manure 7.5 tons / ha, P2 = sorghum plants with a fertilization dose of solid organic fertilizer goat manure 15 tons / ha, P3 = sorghum plants with a fertilization dose of solid organic fertilizer goat manure 22.5 tons / ha, P4 = sorghum plants with a fertilization dose of solid organic fertilizer goat manure 30 tons / ha Based on statistical analysis, it was found that the effect of giving solid organic fertilizer goat manure on the nutritional quality of sorghum plants (Sorghum bicolor L. Moench) showed no significant effect (P.> 0.05) on dry matter and ash content variables. While the variables of crude protein, crude fiber, and crude fat showed very significant results. (P. <0.01). The results of the study showed that solid organic fertilizer goat manure was able to improve the nutritional quality of sorghum plants. These results indicate that the research conducted was positively correlated. Further research is needed to determine the optimal dosage of solid organic fertilizer. The best dosage is 22.5 tons/ha.
