Abstract

Abstract. Jamarun N, Pazla R, Arief, Jayanegara A, Yanti G. 2020. Chemical composition and rumen fermentation profile of mangrove leaves (Avicennia marina) from West Sumatra, Indonesia. Biodiversitas 21: 5230-5236. This study aimed to determine the potential of mangrove leaves of Avicennia marina for ruminant animal feed. Laboratory tests were carried out on A. marina with three replicates. Parameters measured were proximate and fiber contents, rumen fluid profile (pH, NH3 and VFA), digestibility of nutrients (DM, Ash, CP, CF, NDF, ADF, cellulose, and hemicellulose), macro and micro mineral contents, and phytochemical compounds. The results showed the nutritional content of A. marina were CP 13.37%; Ash 7.17%; lignin 7.34%; TDN 79%, rumen fluid profile is in reasonable condition, digestibility of food substances is more than 50%, rich in macro and micro minerals and contains phytochemical compounds such as phenols, steroids, triterpenoids, and tannins. Macro and micro minerals content of Ca 0.38%, Na 0.20%, Mg 0.20%, K 0.48%, P 0.51%, S 0.01%, Cl 1.03%, Fe 388 ppm, Zn 164 ppm, Mn 211 ppm, and Cu 128 ppm. This research concludes that A. marina is very potential to be used as a ruminant animal feed.

Chemical Compositions of Selected Browse Species Used as Goat Feed in Bena-Tsemay district of South Omo, South-Western Ethiopia

“…The higher CP concentration for A. marina leaves from this study is might be due to either genotypic potential of tree to fix atmospheric nitrogen and accumulate high content of nutrients which is required for optimum growth and accumulation of more nitrogen in their leaves. The CP concentration of A. marina leaves in this study was higher than reported value of (133g/kg, DM) by [27], (110.4g/kg, DM) by [28] and (151.4g/kg, DM) by [29]. The crude protein of A. seyal leaves in this study was lower than reported value of (169.6g/kg, DM) by [30] from Ethiopia.…”

Increasing the potential of Cajuput leaf waste as cattle feed through fermentation pretreatment

“…Furthermore, high protein content is probably due to an increase in the number of mold cells (Nasseri et al, 2011;Cairns et al, 2019). Crude fiber consists of cellulose, hemicellulose, lignin, and silica, where the content is influenced by age as well as the species of plants (Jamarun et al, 2020). The fermentation process reduced the value of crude fiber in all treatments.…”

Optimization of Rumen Bioprocess through The Addition of Phosphorus and Sulfur Minerals on Ammoniated Palm Leaves and Fronds (Elaeis Guineensis Jacq.)

“…Based on Table 2 below, it can be seen that the fermentation process that occurs in the rumen with the addition of P and S minerals with different doses of ammoniated PLF has been going well with indications of pH values in all treatments in the range of 6.58 to 6.87. This value is still within the normal range (6-7) for microbial growth, development and microbial activity (Church, 1988;Erdman, 1988;Jamarun et al, 2020;Riestanti et al, 2021;Jamarun et al, 2017a) reported that the optimal pH value for the digestibility of the fiber fraction from fermented PLF is 6.74-6.76. The pH value of fermented PLF supplemented with minerals P, Mg and S is 6.80-6.88 (Febrina et al, 2016a).…”

“…In the Dhamasraya area, there are still few who use this garden waste as animal feed. Generally, farmers are more familiar with palm kernel cake as concentrate feed (Jamarun et al, 2020;Arief et al, 2020). Ruminants such as cows, buffaloes, goats and deer have advantages in their digestive organs that can digest low-quality forages such as PLF.…”
