Abstract

The objective of this trial was to study the effects of disodium fumarate on methane and volatile fatty acid (VFA) production of ammoniated rice straw after in vitro rumen fermentation. Two Simmental cattle fitted with permanent rumen fistulas were selected as donors of rumen fluid. A 3×5 two factors design was adopted. Rice straws treated with 0 (untreated), 4% and 6% urea were used as feed samples, respectively, and the samples were supplemented with five levels of disodium fumarate, i.e. 0, 2%, 4%, 8% and 12%, respectively. After fermented for 48 h by in vitro gas production method, the production of total gas, carbon dioxide, methane, hydrogen and VFA was determined. The results showed as follows: disodium fumarate could significantly increase the production of total gas and carbon dioxide (P<0.05), but significantly decreased methane/total gas production and methane/total volatile fatty acid (TVFA) of untreated and ammoniated rice straw (P<0.05). Disodium fumarate could significantly decease the production of acetate and butyrate and acetate/propionate (P<0.05), but could significantly increase propionate production (P<0.05). It is concluded that disodium fumarate can increase the total gas production, but decrease the acetate/propionate and the relative methane production of untreated and ammoniated rice straw. Disodium fumarate can be used for rumen methane emission control.
