摘要：

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 in-situ 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.
