Abstract: The research aims to determine the best silage formulation using pollard and molasses to acidity (pH), vollatyl fatty acid, and in vitro digestibility. The experiment use completely randomized design (CRD) with four treatments and four times replication, so it has 16 units experiment. The four treatments are treatment A = 100% corn straw + 20% pollard + 0% molases; B = 100% corn straw + 10% pollard + 10% molases; C = 100% corn straw + 0% pollard + 20% molases; D = 100% corn straw + 10% pollard + 0% molases; E = 100% corn straw + 5% pollard + 5% molases; dan F = 100% corn straw + 10% pollard + 0% molases. Variables observe are pH, vollatyl fatty acid, and in vitro digestibility in rumen fluid including dry matter, and organic matter digestibility. Results of the experiment showed that nutrient content and acidity on treatment A is highest. Level of VFA total, dry matter digestibility, organic matter digestibility are significant different (P<0,05). Microbes need energy and protein for the growth and could be fullfill from corn straw silage that combination of pollard and molases. It could be concluded that combination of 10% pollard and 10% molases could use by microbes to fullfill the need of energy and protein.
