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.
They also shed. pathogens into the environment at. a much greater rate than calves that. did receive adequate colostrum. The best situation in a beef herd. is for every calf to nurse its dam. in a timely manner â preferably. within the first two to four hours. Occasionally, however, a calf is. unable to nurse because the dam. has large teats or a first-calf heifer. rejects her calf and wonât let it.
