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.
It is important that the calf nurse as soon as possible after birth to get full benefit from her antibodies. Absorbing Antibodies There are several types of antibodies present in the cow's colostrum. Their absorption rate and role in disease prevention varies depending on the class of antibody (IgG, IgM, IgA). calf needs to have about five percent of his body weight soon after birth (1.5 quarts for a 60-pound calf, 2 quarts for an 80-pound calf, 2.5 quarts for a 100-pound calf), and the same amount again about 6 hours later.
