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.

first 3 days of the calf's life. At Beltsville we found that the vitamin A content of colostrum milk varies with the carotene intake of the cow. Cows on pasture yielded colostrum milk up to 12 times richer in vita- min A than cows that had No. 3 grade of timothy hay. Many dairy farms discard the extra colostrum milk, a wasteful practice.
