AB This paper is devoted to the description of the interval of parameters for which the, parameter dependence, general linear th-order ordinary differential equation is disconjugate on a given bounded interval . Such interval is characterized by the closest to zero eigenvalues of the considered problem coupled with the so-called boundary conditions
