Effects Of Indigofera Zollingeriana As Substitute For Concentrate In Elephant Grass-Based Rations (Pennisetum Purpureum) On Availability Of Macro Minerals (Ca, P, Mg, & S) In Kacang Goat

Abstract

This study aims to explore the best level of Indigofera zollingeriana as concentrate substitution in elephant grass-based rations on the availability of macro minerals (Ca, P, Mg, and S) in kacang goats. This study investigated 12 kacang goats weighing 11 to 12 kg were investigated. The data were collected using an experimental method with a completely randomized design (CRD), consisting of three treatments and four replications. They were P1: 60% elephant grass + 30% concentrates + 10% Indigofera zollingeriana; P2: 60% elephant grass + 20% concentrates + 20% Indigofera zollingeriana; and P3: 60% elephant grass + 10% concentrates + 30% Indigofera zollingeriana. The observed variables were the availability of calcium (Ca), phosphorus (P), magnesium (Mg), and sulfur (S). The statistical analysis used was the analysis of variance. Meanwhile, the mean differences were tested using the DMRT test (Duncan’s multiple range test). The results showed that substitution for concentrates with Indigofera zollingeriana significantly affects (P0.05) the availability of Mg and S minerals. This study concludes that the concentrate substitution with 30% Indigofera zollingeriana could increase the availability of calcium (Ca) and phosphorus (P) minerals, but not affect the availability of magnesium (Mg) and sulfur (S) minerals.
