Effect of harvest maturity of maize silage on dairy cow performance and enteric methane emission estimated using the Dutch Tier 3 approach

Research output: Chapter in Book/Report/Conference proceedingAbstract

Abstract

A study was conducted to evaluate the effect of harvest maturity of maize silage (maturity 300, 340, 380 and 420 g DM kg–1) on dry matter intake (DMI), milk performance and insitu rumen digestibility. Enteric CH4 emissions were estimated according to the Dutch IPCC Tier 3 approach. Increasing harvest maturity of maize silage resulted in increased starch content and the proportion of rumen by-pass starch. However, there were no significant effects on feed intake and milk production. Model calculations indicated a small reduction of methane production per unit of DMI with increased harvest maturity.
