Fermentation Profile, Nutritional Quality and Microbial Populations of Melon Plant Biomass Silage Ensiled with Corn Bran

Abstract

Currently, there is no use for melon plant biomass in agriculture and animal feeding. Using this biomass as silage provides a more sustainable production system. Thus, the objective of this study was to evaluate the silage produced with different mixtures of melon plant biomass and ground corn. The experimental design was completely randomized in a factorial scheme (5 × 2) with five replications. The treatments consisted of five mixtures of melon plant biomass between the plant (branch + leaf) and the fruit (melon scrapings) in amounts of 0% fruit, 5% fruit, 10% fruit, 20% fruit, and 100% fruit on an as-fed basis and ground corn in amounts of 0% and 5% AF of the ensiled biomass. The greatest dry matter contents were found in silages with corn and 0 and 5% fruit, which were 225.6 g/kg and 235.2 g/kg, respectively. The highest concentrations of acetic acid were found in the silages with 0% fruit without corn and 20% fruit with ground corn and were 10.96 and 10.00 g/kg DM, respectively. The use of melon fruit biomass with 0%, 5%, and 100% fruit is the most suitable for silage making, and adding ground corn improves silage quality parameters.
