German to English Other Livestock / Animal Husbandry Livestock

Hello,
I am translating newspaper article in German (probably an Austrian newspaper) that uses the term "Lehnvieh". It describes a man who bought a farm in Austria but did not do much to develop the operations of the farm. Here is the excerpt:

"Der vorhandene Stall des Wohn- und Wirtschaftsgebaeudes war leer. Auf den Flaechen weideten nur die Tiere eines Nachbarn als Lehnvieh."

Here is my attempt:

"The available barn on the residential and farming premises stood empty. On the plains, only the animals of a neighboring farm graze as cattle on the hillside."

I wasn't sure if Lehnvieh was a commonly used term in Austria. I did see a couple hits on Google. I see in my dictionary that "Lehne" is used in South Austria to mean "slope" or "hillside". I based my translation on that.

I would be very grateful for any suggestions you have.

Thanks.
