In Vitro Evaluation of Nutrient Digestibility and Microbial Biomass Production in Total Mixed Rations Supplemented with Various Levels of Areca Sheath Waste for Crossbred Dairy Cows

Abstract

An experiment was conducted to investigate the effects of Areca Sheath Waste (ASW) supplementation in total mixed rations on rumen fermentation parameters using an in vitro gas production technique in crossbred dairy cows. Areca sheath waste was added to the total mixed ration at different levels: 0% (control), 10%, 20%, and 30%. The results showed that in vitro true dry matter degradability, true organic matter degradability, total gas production, and microbial biomass production increased by adding up to 10% Areca sheath waste. However, these parameters declined when the Areca sheath waste inclusion was increased to 20% and 30%. Metabolizable energy decreased as the level of Areca sheath waste increased. Notably, methane production was significantly reduced with Areca sheath waste supplementation. These findings suggest that Areca sheath waste supplementation can alter ruminal fermentation in a dose-dependent manner.
