La. Civ. Code art. 599
Current with operative changes from the 2024 Third Special Legislative Session
When the usufruct includes a herd of animals, the usufructuary is bound to use it as a prudent administrator and, from the increase of the herd, replace animals that die. If the entire herd perishes without the fault of the usufructuary, the loss is borne by the naked owner.
