When any livestock is impounded under the provisions of this Chapter and remains without reasonably adequate feed and water for more than 24 hours, any person may lawfully enter the area of impoundment to supply the livestock with feed and water. Such person shall not be liable in trespass for such entry and may recover of the owner or, if the owner is unknown, of the impounder of the livestock, the reasonable costs of the feed and water.
