Hazard: When scaffolds are not erected or used properly, fall hazards can occur. About 2.3 million construction workers frequently work on scaffolds. Protecting these workers from scaffold-related accidents would prevent an estimated 4,500 injuries and 50 fatalities each year.
The amount of immunoglobulin ingested is also a major determinant of final serum immunoglobulin concentration. A practical rule-of-thumb is to feed 5 to 6% of the calf's body weight within the first 6 hours and repeat the feeding when the calf is about 12 hours old. For an 80 pound calf, this will equate to approximately 2 quarts of colostrum per feeding.
However, a calf that has undergone a difficult birth or has not had an opportunity to nurse within one to two hours after birth should be fed colostrum. Feed fresh or slowly thawed frozen colostrum at 5 to 6 percent of the calfâs body weight (about 2 quarts for an 80-pound calf) within the first six hours of life. Then feed the same amount again about 12 hours after birth. This may be done using a stomach tube if the calf is too weak to nurse.
