Description
Forage systems development In the highlands of Rwnion Island is based on grass crops. Silage is becoming more important, and roundbale wrapping is increasing. Since 1990, experiments have concerned technical data on different sites (39) and silage composition (168 samples). Descriptive statistics (multivariate analysis) have been used to determine relationships between silage quality and harvesting conditions. Pour synthetic notations have been calculated in relation to silage preservation. As in other studies, silage quality was !iighly related to dry matter (DM) content. Above 33% DM, silage was well preserved, but quality was poor below 20% DM. In different areas, silage preservation varied according to harvesting and weather conditions. In most statistical analyses, the molasses rate was not a discriminating factor, but it favoured lactic acid bacteria for silage harvested with more than 25% DM; below 25% DM, molasses was not sufficient to give good preservation. Almost all silages were highly contaminated by Clostridium tyrobutyrlcum spores, even with high DM. Discriminating variables for preservation are: DM, % of temperate species, mechanisation difficulties, weather conditions, pH and wrapping film colour.
