Second, wear nasal parts should be moderate. The nose of the cow is better at the thinnest part (no cartilage, thin and soft place) slightly in front of the middle part of the nose (cartilage part). If worn in the cartilage at the back of the nose, although it is not easy to lack the nose, but the wound is difficult to heal, and the sensation of pain when traction is too strong, it is difficult for the cattle to exercise training; if worn in the front of the nose Where there is a thick layer of meat; in the future, not only will it not follow the command but it will easily cause a lack of nose.

For example, metal nose rings made of copper, iron, etc., should be put on the nose sleeves and plastic hoses. , to ensure that the surface of the nose ring is smooth. After the cow wears the nose, always check the nose ring regularly. If the nose ring is found to be too big or too small and the surface is rough, it should be replaced in time to prevent the bovine nose from being damaged.

He had to wait for 1 to 2 stars to wait for the wound to heal completely before being able to pull on the tether. When hauling and darting the cattle, he must walk in front of the man and he followed.
