Abstract: The study was carried out to determine the effect of diets containing different parts of Andrographis paniculata on cumulative gas production, dry matter digestibility, methane and volatile fatty acids production in goats using in vitro gas production technique. The leaves, stems and roots of Andrographis paniculata (AP) were analysed for total polyphenols. Leaves of AP were found to contain the highest concentration of polyphenols; 3.08% Tannic Polyphenol (TP), 0.46% Hydrolysable Tannin (HT) and 0.19% Condensed Tannin (CT). The Non-Tannic Polyphenols (NTP) were estimated as 2.43% of the total polyphenols in the herb. Four diets were formulated three of which contained 1% each of the parts analysed (APL = leaves, APS = stems and APR = roots) and not containing Andrographis paniculata (APO) which was used as the control and tested for digestibility via in vitro gas production technique. The results indicated that VFAs, IVDMD, gas production and pH of the rumen fluid were not significantly affected (p>0.05) by the experimental diets except for ammonia (p<0.05). The results suggest that goats can utilize nutrients from feeds containing AP without compromising the production of VFA and dry matter digestibility.
