Pengaruh Level Substitusi Rumput (Bothiriochola Pertusa) dengan Kangkung Terhadap pH, Konsentrasi VFA dan Amonia Cairan Rumen Ternak Kambing Kacang

Abstract

This study was aimed to determine the effect of substitution level of Bothhriochloa pertusa grass with water spinach on pH, Volatile Fatty Acid, Concentration and ammonia in rumen fluid of peanut goat livestock. This study used 4 male kacang goats aged 8-1,5 years with a body weight range of 13,3-19,8 kg with an average of 16,2 kg. This study used a Latin Square design (RBSL)  with four treatments and four replication periods. The four treatments were P0: Bothriochloa pertusa grass 60% + leucaena leucochephala 40%, P1: Bothriochloa pertusa grass 45% + leucaena leucochephala 40% + water spinach 15%, P2: Bothriochloa pertusa grass 30% + leucaena leucochephala 40% + water spinach 30%, P3: Botriochloa pertusa grass 15% + leucaena leucochephala 40% + water spinach  45%. Parameters measured were pH, Vollatile Fatty Acid (VFA) and Ammonia (NH₃). The data obtained were analysed using Analisis of Variace (ANOVA. The results of this study indicate that pH, P0: 5.89 ± 0.22^b, P1: 5,82 ± 0,1^b, P2: 5,72 ± 0,17^ab,  P3: 5,57  ± 0,1^a . VFA (mM), P0: 132,03 ± 3,99^a, P1: 127,14 ± 3,99^a, P2: 129,58 ± 6,31^a, P3: 132,76 ± 4,95^a.  NH₃ (mg/dl), P0: 15,89 ± 2,12^a_, P1: 15,14 ± 0,97^a, P2: 15,52 ± 2,45^a, P3: 16,41 ± 0,1^a. The results of statistical analysis showed that the effect was not significant on the concentration of pH, concentration of VFA and rumen fluid ammonia of peanut goads. The conclusion of this study is that the substitusion of Bothriochloa pertusa grass with water spinach at different levels has the same effect between the treatments on pH, VFA concentration and rumen fluid ammonia of male peanut goat.
