In vitro fermentation characteristics and nutrient digestibility of rations based on corn stover silage (Zea mays L., 1973) and Ceara rubber tree leaves (Manihot glaziovii Mull. Arg., 1874) for Etawa crossbred goats.

Despite being abundantly available and nutritious, corn stover and Ceara rubber tree leaves are rarely used as livestock feed. However, these agriculture byproducts contain hard to digest nutrients to be used as feed for livestock. This study evaluates the fermentation characteristics (pH levels, ammoniacal nitrogen (N-NH3), and total volatile fatty acid (VFA) production and nutrient digestibility (dry matter digestibility_DMD, organic matter digestibility_OMD) of a silage-based diet composed of a mixture of corn stover and Ceara rubber tree leaves in Etawa crossbred goats in vitro.
