Went out for a run on the mtb last night on some local bridleways. Crossing a field I had to squeeze past a heard of cows, which moved a bit as I approached. As there was no other way out of the field I thought I will calmly go by although it was crowded. However as I got to the point of no return a very large bull appeared probably 6' at his shoulder. I managed to get to the gate and lock it, but was a touch freaked. A cursory search on the Internet tells me certain bulls with cows should not be kept in fields with a right of way across. Two questions, can anyone Id the type of cattle from the pic below? I thought they were friesians there is a lot of dairy farming in Cheshire but there are some brown and blacks there. The bull is the massive black one. Also is it worth reporting to the local rural plod? I would hate a family walking with a dog to spook them and have a serious problem, the field had a mains voltage electric fence around it so no additional easy routes to bail if anything went wrong.
