| Improving feed quality and efficiency is crucial for sustainable aquaculture practices, particularly for giant gourami (Osphronemus gourami) cultivation. One of the useful strategies is the inclusion of kombucha tea in the diet. This study aimed to evaluate the effect of different levels of kombucha tea supplementation on the intestinal histomorphology and growth performance of giant gourami. A completely randomized design (CRD) with five treatments and four replications was used. The treatments consist of a control diet (T0) and diets supplemented with 10 ml (T10), 15 ml (T15), 20 ml (T20), and 25 ml (T25) of kombucha tea per kg of feed. The fish were fed three times daily to satiation for 40 days. The result showed that kombucha tea considerably increased the villi length (p<0.05), enhancing nutrient absorption and fish growth performance (p<0.05). The highest specific growth rate (2.21±0.12 %.day-1) and feed conversion ratio (1.42±0.09) were observed in T25 group, while statistically similar to T20 (p>0.05). These findings suggest that supplementing kombucha tea on a diet improves intestinal morphology, promoting better feed utilization and growth performance. This strategy offers a sustainable approach to enhancing feed efficiency and productivity in giant gourami aquaculture. | ||
