Effect of soaking mangrove fruit (Sonneratia alba) with lime water on crude protein, crude fiber, and nitrogen free extract content as a ruminant feed

Abstract

Abstract The mangrove plant is among the strees found growing in the seaside zone, one part by the mangrove plant that Could be utilized as livestock feed for ruminants is mangrove fruit. Mangrove fruit is usually rarely used so it only rots and pollutes the coast. The aim in thus study is to see effects by mangrove fruit tannin reduction with lime water on crude protein, crude fiber, and NFE content. This study used 4x3 Faktorial pattern group randominsation plan using 2 seplicates. The first factor is the concentration by lime water with 4 levels, that is T1 (1% lime water), T2 (3% lime water), T3 (5% lime water), T4 (7% lime water). The second factor is different soaking times with 3 times, namely 10 minutes, 20 minutes, and 30 minutes. The conclusion of the research on soaking mangrove fruit with lime water gives a very significantly different effect on crude protein, crude fibre, and NFE content. The highest crude protein content is in the A1B1 treatment with a grade of 8.1%, the best crude fibre was in the A3B3 treatment with a value of 24.91%, and NFE was in the A1B1 treatment with a value of 58.07%.
