When a sheriff or other officer shall levy an execution on livestock, he shall provide for its sustenance until sold or otherwise legally discharged from the execution. Upon the return of the execution, the court, in cases where the compensation is not fixed by law, shall settle and adjust what the officer shall be allowed for his expenses incurred by providing for the stock, and also reasonable expenses of keeping personal property levied on by him, and the same shall be taxed as costs. The officer may retain the same out of the money arising from the sale of the property.
