Once radiopharmaceuticals enter the body and travel to an organ, they begin to interact with the processes of that organ. The radioactivity is picked up by cameras or computers and used to map the process. For example, an ultrasound can show an image of an organ and reveal if a tumor or other abnormality is present. Nuclear medicine can show how the process of glucose metabolism is functioning in the organ.
250g bags of our biltong can last up to 4-months, and we have food testing certificates to prove this, however, we do not advise that you keep it that long. The larger the bag of biltong, i.e 500g or 1kg, the more moisture is contained within the sealed bag.
How long should a calving season last? The rule of thumb is 90 days to insure that all the cows calve within a year, but the length should be based on herd and management needs from manager time and marketing. The optimum calving season would have 60% of the cows calving in the first 30 days of the calving season. Conversion to a shorter calving season will highlight two things in the herd. First, less fertile cows can be identified and these freeloaders can be eliminated.
