(a) Owners of land, or their assignees, shall have a lien upon all livestock raised, grown, or grazed upon rented land for the rent of said land for the current year, and which shall be paramount to all other liens. The lien shall exist only when the land is leased or rented or used for pasturing or grazing purposes.
(b) For the enforcement of such lien, the owners of such land, or their assignees, may have process of attachment from any court having jurisdiction of the amount claimed, leviable upon the stock upon which the lien exists
(1) When such claim is due and the defendant upon demand fails or refuses to pay the same;
(2) Whether such claim is due or not when the defendant has removed any part of such stock from such land without the consent of the landlord without paying the rent, or if the claim has been assigned without the consent of the assignees;
(3) Whether such claim is due or not, when the plaintiff has good cause to believe that the defendant is about to remove any part of such stock from the land without paying the rent and without the consent of the owner of such land or the assignee, if the claim has been assigned.
