The effects of treating cereal straws with NaOH and ammonia on methane production by sheep are reported. One oat, two wheat and two barley straws were either untreated or treated with NaOH (45 kg t−1 dry matter (DM)) and ammonia (35 kg t−1 DM). The straws were supplemented with urea and sodium sulphate as appropriate to provide a dietary N S ratio of 14.4 : 1 and given ad libitum to mature wether sheep. Methane production was measured in open circuit respiration chambers following a 20 day period on each diet. The digestibility of various feed fractions was measured both in vitro and in vivo. Methane production as a proportion of gross energy intake (range 0.047–0.067) was not significantly affected by treatment, although the volume of methane produced per animal was significantly (P |
