The key to utilizing the tables is to know what table to use based on three levels of mature bull size. The three levels are bulls at 1,700 pounds, 2,000 pounds and 2,300 pounds. The daily maintenance or zero-weight-gain ration (hay or grass) varies by the size of the bull. A 1,700-pound bull needs a daily intake of 33 pounds of dry matter that is 7 percent protein and 46 percent total digestible nutrients (TDN).
Sores, blisters, or bumps on the scalp. Painful sores, blisters, or bumps that develop on the scalp may be caused by: 1  Infection of the hair shafts (folliculitis) or the skin (such as impetigo). 2  An allergic skin reaction (contact dermatitis).
Sometimes, however, a tender scalp may be caused by hair that is very heavy and pulls on the scalp. There are even some conditions, such as ringworm and acne, that contribute to a sore scalp. In some cases, a person may even develop a tender scalp because of overly energetic combing and brushing.
