Inhibition of ruminal microbial methane production by β-cyclodextrin iodopropane, malate and their combination in vitro

Summary The objective of this study was to evaluate the effects of different concentrations of l‐malate (0, 5, 10 and 20 mm), 2‐iodopropane‐β‐cyclodextrin complex (CD‐IP) (0, 0.1, 0.2 and 0.4 mm) and a combination of malate (10 and 20 mm) plus CD‐IP (0.2 and 0.4 mm) on methane production from corn s...

Description
Summary:Summary The objective of this study was to evaluate the effects of different concentrations of l‐malate (0, 5, 10 and 20 mm), 2‐iodopropane‐β‐cyclodextrin complex (CD‐IP) (0, 0.1, 0.2 and 0.4 mm) and a combination of malate (10 and 20 mm) plus CD‐IP (0.2 and 0.4 mm) on methane production from corn starch. Ruminal fluid was collected from dairy cows, mixed with phosphate buffer (1 : 2) and incubated (30 ml) anaerobically at 38 °C for 6 h with or without additives. Fermentation of corn starch in the presence of malate resulted in an increase (p
