Separating the effects of pre-ensiled chemical and microbial composition on silage fermentation and aerobic stability

Spörndly, Rolf

Abstract

Ensiling results of different forage types usually differ. For instance, legume silages usually contain more acetic acid, butyric acid and ammonia-N and are aerobically more stable than maize silages (Muck & O’Kiely, 1992; O’Kiely & Muck, 1992; Wilkinson & Davies, 2013). However, as to what extent these differences are related to chemical or microbial composition is yet unknown. In recent work by Mogodiniyai Kasmaei et al. (2015), a new ensiling methodology was introduced that enables sterilization of forages and inoculation with original microfloras. In the present experiment, we have further utilized this methodology to separate the confounding effects of microbial and chemical composition on silage fermentation and aerobic stability.
