Extract

Previous studies have identified small but significant differences in in vitro methane (CH4) production between perennial ryegrass cultivars harvested pre-heading date. This raises the possibility that enteric CH4 production could be reduced through cultivar selection. The aim of this study was to assess the effect of harvest date on in vitro CH4 output of two cultivars previously identified as having a high and low methanogenic potential (Lovett et al., 2003).
