Abstract
Fencing to controle the behavior of cattle escaping is very important for the pasture utilization. Effects of various fences were experimented on the grazing behavior with the feeder adjusted the wire height. Two cows used in this experiment were Japanese Shorthorn with mean height of 132cm and mean weight of 533kg. The grazing behavior was studied on the frequency of sticking of cattle's poll out of the fence. Its frequency decreased as the post's span subdivided 2, 3, 4, 6, 8 and 12 meters in the fence became short and as the feeder became more distant among 0.5-1.5 meters from the fence line. Its frequency was found often in the height of 60-100cm in case of the 3, 4 or 5-wire fence with the wire of round barbed or a combination of both wire. This height was suitable for 45-75% of the height of cattle. The difference between the wire tension of 25 and 50 kgf was not clear, but the barbed wire was more effective to controle the cattle sticking rather than the round and the combination wire. The behavior of sticking out of the fence dropped the wire tension, and it was surmised that the cattle was apt to stick not over the wire but under one in case of the barbed wire fence.
