Nutritional Analysis of Mangrove Leaves (Rhizophora apiculata) Soaking with Lime Water for Ruminants Feed

Abstract

Mangrove leaves (Rhizophora apiculata) has potential as animal feed because their had high protein content around 11,72%. Mangrove leaves contain anti-nutritional substances in the form of tannins. Tannins are antinutrient compounds that bind to proteins, carbohydrates (cellulose, hemicellulose and pectin), vitamins and minerals. Boiling can reduce the content of tannins and other anti-nutrients because phenolics are soluble in hot water and lime can hydrolyze tannins causing the active phenolic tannin groups to become inactive. The purpose of this research was to determine the effect of boiling time on the nutritional content of mangrove leaves. The treatments given soaking with lime water 10 minute, the treatment consist of : A : control, B : 5% lime, C : 10% lime, D : 15% lime. The research method used Randomized Block Design (RBD) with 4 treatments and 5 replications. The best result of this research was B Treatment with 5% lime which resulted in the nutritional value includes 93,32% dry matter, 7,934% ash, 92,066% organic matter, 8,16% crude protein, 15,91% crude fiber, 3,812% crude fat, 27,64% acid detergent fiber, 35,86% neutral detergent fiber, 13,15% 13,15% cellulose, 8,22% hemicellulose, and 13,05% lignin.

In vitro Evaluation of Mangrove Leaves (Rhizophora apiculata) and Native Grass Based on Phytochemical, Nutritional and Fiber Degradability, Rumen Liquid Characteristics and Gas Production

“…In this study organic matter produced ranged from 90.00%-91.11%. The content of this organic material is not too different from research Sari et al (2022) results of proximate analysis organic matter of Mangrove Leaves (Rhizhopora apiculata) soaking with lime water around 91.14%-92.07%. High digestibility of organic matter in this study, it is suspected because dry matter digestibility in the study higher.…”

“…Based on the table above, it was found that the higher used of mangroves in the treatment resulted in a high total phenol and tannin combination, this is based on previous research by Sari et al (2022) anti-nutritional substances contained in mangrove leaves in the form of tannins and another polyphenol compounds. The total phenol and tannin content are related because tannins are included in secondary metabolites synthesized on plants and classified as polyphenolic compounds and had ability to form complex compounds with another macromolecule.…”

“…Anti-nutritional substances liked polyphenol compounds and tannin are contain in mangrove's leaves (Sari et al 2022). Hay mangrove leaves processing aims to reduce water content due to harvesting carried out in large quantities, so it is hoped that the nutritional content is maintained.…”

Study of Avocado Seed and Banana Peel Processing as Corn Element Substitution in Japanese Quail (Coturnix-Coturnix Japonica) Ration

“…The husk ash substrate can be used as a cheap and easily available NaOH replacement alkaline solution, this is in accordance with the opinion of Jamarun et al (2021) which explains that husk ash water functions as a base that is cheap and easily obtained in rural areas, it can be used as a substitute for NaOH. Furthermore, Sari et al (2022) also explained that hydrolysis with husk ash water is more profitable than other types of alkali. The use of processed avocado seeds with NaOH up to 20% does not interfere with quail performance, while above 20% causes quail performance to decline (Dahyuni 2004).…”

In Vitro Digestibility of Hay Mangrove with Native Grass

“…For farmers in coastal areas, competition in land use is also a problem because the land is used for the tourism sector which is profitable in the short term. So that land for forage is limited, it is necessary to look for alternative feeds that are available in a sustainable manner (Sari et al, 2022).…”
