Insuring Livestock Once you have purchased your alpaca ownership transfers to the purchaser. So if you are not in a position to collect alpacas immediately, getting insurance is recommended. The cost of the alpaca may not warrent insurance. If you are not in a position to collect the alpacas immediately you should seek clarification about what will happen in the event of injury or death of the alpaca while they remain on the farm of the seller.
Many interstate buyers use livestock transport services. You should always find out if the carriers policy covers accidental death or injury while being transported.
