The cow has a bloody nose and is in urgent need of help.

This post was finally edited by lihuawei4646 at 07:30 on 2009-12-7. There was a cow with sudden nosebleed from last night, and it is still running today. Both nostrils are bleeding, which is the kind of clear nose mixed with blood, but there is more blood, which does not affect food intake. For cows in the later stage of lactation, the formula of feed is: concentrate 6kg per day, sun-dried grass is free to feed, there are no other excipients. The cows in the same column did not have any response, feeding and management as usual, the expert came up with an idea, thank you! If there are no other symptoms, it should be the ruptured capillaries of the nose. Cold water can be applied to the forehead. Also want to consider the question of the brain-passing study, please master answer!
