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.
The first milk that a ewe produces after lambing is called colostrum. It is very nutritious and contains antibodies that help lambs fight off diseases during the early part of their lives. The ewe only produces colostrum for 24 hours. It is essential that lambs consume adequate colostrum. An amount equivalent to 10 percent of their body weight is recommended. Lambs will start to nibble on solid food (hay, grass, and grain) soon after birth. By the time they are 4 to 6 weeks old, they may be obtaining as much as 50 percent of their nutrients from sources other than their mother's milk.
