Chest Tubes After Open Heart Surgery. When a patient has a chest tube after heart surgery, the tube is inserted near the sternum (breastbone), and is intended to drain any blood that accumulates away from the surgery site.
Currently there are five major types of sorghum grown: 1) Grain sorghum with dwarf varieties that grow 2 to 5 ft tall for easier combining. 2) Forage sorghum which grows 6 to 12 ft tall, produces more dry matter tonnage than grain sorghum, is coarse stemmed and used for silage.
Sorghum was grown primarily as a source of sugar for syrup until the settlement of the semiarid West created a demand for drought-resistant forage crops. By the 1950s, about 90% of the acreage of sweet sorghums in the United States was grown for forage.
