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.
Grain sorghum is used primarily as a livestock feed. Planted area generally rangedbetween 15 and 20 million acres until the late 1980's, when acreage dropped to the 10 to 15 million range. Themajority of the sorghum acreage not harvested for grain, is harvested for silage.
