Overview

In vitro study evaluates gas and methane production in livestock feed, suggesting effective supplementation strategies.

Key Points

  • This study aims to assess the impact of supplementing Eragrostis curvula with Searsia lancea on fermentation and methane output.
  • Conducted an in vitro fermentation study using a semi-automated pressure transducer technique.
  • Compared grass hay alone (control) to hay supplemented with 15% or 30% of Searsia lancea leaf or silage meal.
  • Total gas and methane production was measured at multiple time intervals.
  • Used a complete randomized design with four replicates for each treatment.
  • Supplementation with 15% S. lancea increased gas production significantly during the first 24 hours.
  • 30% supplementation of S. lancea also increased gas production but to a lesser extent.
  • S. lancea meals effectively reduced methane production at both 24 and 48 hours.
  • 15% and 30% silage meal reduced methane production initially and later, indicating mixed effects.
