Abstract

The present study investigated the effects of two nutraceutical plants – Petiveria alliacea and Waltheria indica on in vitro gas production, dry matter degradability (DMD) and methane production of two dairy cow diets (high forage [HF] and high concentrate [HC]). A factorial arrangement of two diets and two nutraceutical plants with four levels of inclusion (2.5, 5.0, 7.5 and 10.0%) was used. Results demonstrate substrate x inclusion level interactions were significant (P<0.05) for gas volume, DMD and methane production. P. alliacea at 2.5 and 5.0% suppressed gas production in high forage (HF) by 7.5 and 7.9%, respectively and W. indica inclusion levels of 2.5 and 5.0% increased gas production. All inclusion levels of P. alliacea suppressed gas production in high concentrate (HC) diet and the lowest gas volume was noted in the 10.0% treatment. Contrary to this observation, 2.5% inclusion level of W. indica had the lowest gas volume in the HC diet. Compared with the control, DMD of HF diet was improved with the inclusion of both plants except for P. alliacea at 2.5 and 5.0%. There was a significant decrease in methane production across all levels of inclusion for both medicinal plants and substrates; P. alliacea at 10.0% decreased methane by 31.2%. Substrate x inclusion level interactions (P<0.001) were noted for neutral detergent fiber degradability (NDFD) and acid detergent digestibility (ADFD). P. alliacea at 2.5% and 10% inclusion levels reduced NDFD in HF and HC diets, respectively. A similar trend was noted with P. alliacea inclusion. Based on the present results, inclusion of P. alliacea above 5.0% and W. indica at all inclusion levels were able to improve DMD. Both medicinal plants reduced methane concentration irrespective of inclusion level.
