On complying with the provisions of this article, the owner of a stallion or bull shall have a lien on each mare or cow served together with the foal or calf of such mare or cow from such service, for the amount agreed on at the time of service, or if no agreement was made, for the amount specified in the statement hereinafter required to be filed, if within twenty months after such service he files a notice of such lien with the proper officers and in the same manner as is required to perfect a security interest under paragraph two of subsection (a) of section 9-501 of the uniform commercial code. Such notice of lien shall be in writing, specifying the person against whom the claim is made, the amount of the same and a description of the property upon which the lien is claimed, and such lien shall terminate at the end of eighteen months from the date of such filing, unless within that time an action is commenced for the enforcement thereof, as provided in sections two hundred six to two hundred ten, both inclusive, of this chapter, for the foreclosure of a lien on chattels.
