It is very difficult to supply a feed in a frog farm because a frog eats live feeds responding to movable living organisms. It is difficult to continually supply live feeds to a frog and to be not economic due to cost. The present invention relates to a method which makes a feed for a frog and tries to give a frog the same. The method pierces a hole in a center of a feed which is size to eat and is coupled to a vibration shaft having a predetermined height from the ground where a frog can snatch the feed after threading the feeds using an elastic thread (e.g. fishing gut) and tightly making a knot on the both ends, thereby, the frog snatches the swingy feeds while swinging the feeds threaded the elastic thread through vibration caused by using a motor in the vibration shaft and the frog eats the feed again because the feeds of an upper portion come down by weight and vibration and thus can increase productivity because of not supplying live feeds. |
