Mineral status of soil, sea water, and mangrove (Avicennia marina) forages in several coastal areas of West Sumatra

Abstract

Background and Aim: The availability of minerals in the soil affect the mineral content of mangrove leaves. This study aimed to determine the macro- and micromineral contents in the environment and mangrove leaves (Avicennia marina) as animal feed in the coastal areas of West Sumatra, Indonesia. Materials and Methods: In this study, soil, water, and mangrove leaves were extracted from the mangrove plant's environment. The mineral contents were determined using the atomic absorption spectrophotometer of Beijing Rayleigh Analytical Instrument Corporation (make and country of origin). The total phenol and tannin contents were determined using the Folin–Ciocalteu and hide-powder methods, respectively. Results: The mineral content of the soil affected the mineral content of the plants. The soil and leaves of A. marina in the Pariaman area were richer in terms of macro- and microminerals. The soil had pH value, organic carbon content, leaf nitrogen content, phosphorus, calcium, and potassium of 5.65, 4.21%, 3.39%, 0.17%, 1.99%, and 0.54%, respectively. A. marina leaves had a total phenol and tannin contents of 24.51 mg GAE/g check the unit and 4.09%, respectively. Conclusion: This research showed that the mineral content in the soil in several mangrove areas in West Sumatra has a positive correlation with the mineral content in the leaves of A. marina, which have a complete mineral content. Therefore, A. marina leaves could be recommended as a mineral source for ruminants.

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

“…The obtained data were analyzed using General Linear Model by IBM SPSS Statistics 26 (Yanti et al, 2021a). Data groups that showed statistical significance (p<0.05) were further analyzed using Duncan's Multiple Range Tests (DMRT).…”

“…There is a breakdown of protein into ammonia which will be used as the main nitrogen resource for microbial synthesis in the livestock's rumen (Russell et al, 2009). The mangrove plant lived in the littoral area are considered to have the potential become forage source (Yanti et al, 2021a;Sari et al, 2021).…”

“…On abomasum tannin and protein can release from complex binding because the pH condition was low which enables protein degrade by the enzyme, like pepsin. Hence, amino acids it contains are readily available to livestock requirement (Yanti et al, 2021a).…”

Impact of Mangrove Leaves (Rhizophora apiculata) in Limewater on Nutrients Digestibility, Rumen Ecosystem and in vitro Methane Production

“…(Jamarun et al, 2021) said that boiling can reduce tannin levels. According to Yanti et al (2021b) boiling with an alkaline solution can reduce the tannins of a plant.…”

Empowerment of Abandoned Ponds for Sustainable Mangrove Rehabilitation Activities in Percut Sei Tuan, Deli Serdang, Indonesia

“…shows the highest number of individuals for the seedling was A. marina with a total of 756 idv/ha. A. marina can grow in extreme environments, where water and soil experience ups and downs carrying various types of minerals ([16]. At the sapling stage, the highest number of individuals was found in A. marina with a total of 53 idv/ha, and the lowest was B.…”
