This study investigated the dietary effect of feeding Curcuma longa rhizome powder, below and above 10g/300g of feed, on the performance and rumen microbial isolates of growing goats. Thus, basal diet was formulated and 300g of the concentrate was fed daily to each of the goats while adding turmeric rhizome powder at 0g (Diet A), 5g (Diet B), 10g (Diet C), and 15g (Diet D), respectively to the concentrate. Twenty west African dwarf (WAD) goats were used for this study which lasted 63 days. Parameters were taken on feed/nutrient intake, digestibility, weight change, and feed conversion ratio were calculated. Rumen liquor was collected from all the goats for rumen pH, ammonia, volatile fatty acids and microbial (bacterial, coliform or fungi) isolates determination. Data generated were subjected to appropriate statistical analysis. All parameters observed were significantly (P<0.05) influenced by the supplementation of Curcuma longa rhizome powder. Goats fed diet C (10g turmeric/300g of feed) had the highest weight gain (2.83 kg) and daily weight gain (50.60 g/day). The least acetic (2.55mmol/200ml) and highest propionic acid (6.10mmol/200ml) production in the rumen was recorded for goats fed diet C. Microbes identified included; bacteria (Lactobacillus acidophilus, Streptococcus faecium and Klebsiella aerogens), coliform (E. coli and Salmonella serviella) and fungi (Salmonella serviella and Penicillium oxysporium). From result, it further confirmed potential of turmeric to inhibit rumen microbes (fibrolytic bacteria), if fed above 10g/300g feed. Supplementing goat’s diet with turmeric rhizome powder at 10g/300g feed yielded the improved feed utilization and weight gain.
