Abstract

The effect of additives on quality, protein degradability, intestinal digestibility and feed intake of wilted grass silages

Highlights

Organic acids and inoculants containing lactic acid bacteria can improve fermentation quality and reduce dry matter (DM) losses of grass silages
Rooke et al (1983) and Mc Donald et al (1991) found that protein in grass silage is rapidly degraded in the rumen and the resulting ammonia-N may be poorly utilized for microbial N synthesis
There is no clear evidence that decrease of proteolysis by silage additives is correlated with protein degradability in the rumen

Summary

Introduction

Organic acids (propionic and formic acids) and inoculants containing lactic acid bacteria can improve fermentation quality and reduce DM losses of grass silages. QUALITY OF GRASS SILAGE WITH ADDITIVES preserved (Selmer-Olsen and Mo, 1997; Huhtanen, 2001). Rooke et al (1983) and Mc Donald et al (1991) found that protein in grass silage is rapidly degraded in the rumen and the resulting ammonia-N may be poorly utilized for microbial N synthesis. The effects of forage preservation methods and impact of silage additives on ruminal protein degradability were studied (Rooke et al, 1983; Polan et al, 1998). There is no clear evidence that decrease of proteolysis by silage additives is correlated with protein degradability in the rumen. There is no clear evidence that decrease of proteolysis by silage additives is correlated with protein degradability in the rumen. Jaakkola et al (1993) showed that protein protected from proteolysis in the silo is still degradable in the rumen
