The aim of this experiment was to study the effect of supplementation of phytoadditive mixture (PAM), Curcuma longa and Ocimum sanctum in 1:1 with or without palm oil on growth performance, gut health and economics of low body conditioned Black Bengal goats (BBG) (Capra aegagrus hircus). For this experiment, 21 similar body weight (BW) (7.75-8.2 kg) and age (8-10 months) female goats were randomly distributed into three comparable groups including control (no supplementation), T1 (PAM@15 g/kg dry matter [DM] conc.) and T2 (PAM with palm oil @ 0.05% BW of goat) for three months. The results of this study indicated the highest (P<0.001) BW, average daily gain (ADG) and body condition score (BCS) in the T2 group, followed by T1 and the control group. Improved gut health (P<0.001) was observed in the treatment groups than in the control group. There was (P<0.05) a medium to high degree of correlation between experimental goats’ growth performance and gut health. Economic analysis showed the highest returns over the control group in T2, followed by the T1 group. It can be concluded that supplementation of PAM containing equal proportions of Curcuma longa plus Ocimum sanctum (15 g/kg DM conc.) with palm oil (0.05% BW) may economically improve growth performance and gut health of low body condition BBG.
