Abstract

This study was conducted to investigate the effects of herbs and humic acid supplementation on Dry Matter, Organic Matter, Crude Protein, and Crude Fibre digestibility of local goats. Twenty-four growing female goats were randomly allocated in completely randomized design experiments with 4 treatments and 6 replications. The 4 treatments were the addition of herbs with No humid acid (T-0), Herbs + 2 g humid acid/goat (T-1), Herbs + 4 g humid acid/goat (T-2), and Herbs + 6 g humid acid/goat (T-3). The herbs used were a mix of Melastoma malabatrichum, Andrographis paniculata, Curcuma longa, and Nigella sativa. All goats were given the same amount of Tofu waste, fermented Palm Oil Sludge, and grasses. Feed offer, feed residue, fecal output, and digestibility were measured during a 7-day measurement period, with an adaptation period of 3 weeks. Data were analyzed using analysis of variance followed by Duncan's post-hoc test. Results showed no difference among all treatments on the intake of dry matter intake and organic matter, crude protein, and crude fiber. ADG and DMI/metabolic body weight of T-1 were significantly higher than that of the other treatments. The addition of herbs and humic acid tended to increase dry matter intake per metabolic body weight and increased significantly (P<0.05) for all feed digestibility measures. The digestibility of goats with supplementation of herbs and humic acid 2 g/goat (T-3) was significantly higher (p<0,05) than that of all treatments. It could be concluded that a combination of herbs and 2 g humid acid supplementation improves the digestibility of local goats.
