Whoever pastures, feeds or shelters animals by virtue of a contract with or by consent of the owner has a lien thereon for the amount due for such pasturing, feeding or sheltering, and for necessary expenses incurred in the proper care of such animals and in payment of taxes assessed thereon, to secure payment thereof with costs, to be enforced in the same manner as liens on goods in possession and choses in action. The court rendering judgment for such lien shall include therein a pro rata amount for such pasturage, feed and shelter provided by the lienor from the date of the commencement of proceedings to the date of said judgment. <div
