INTROUCTION:
I have been asked to analyze some data about the disease Colic in horses from a sample of 296 horses from the Guelph University in Canada. These 296 horses are presenting with the symptoms of Colic. I will investigate the two variables of the capillary refill and the pulse of horses. I will be looking to see if there is a difference between the two particular groups but analyzing with only one particular variable. In my investigation I will be determining the difference in the pulse of horses measured in beats per minute (bpm) compared to the time taken to refill the capillaries. The longer the refill, the poorer the blood circulation. It is the result of clinical judgment. According to research (http://www.merckmanuals.com /vet/digestive_system/colic_in_horses/overview_of_colic_in_ horses.html) I have done, Colic is a broad term that veterinarians use to describe abdominal pain in horses. Colic has many different causes. An evaluated heart rate is always a good indicator of pain and is an effective indicator of severe colic. A normal resting heart beat for an adult horse should beat between 30-40 beats per minute. However, this differs for athletic horses as they may have a heart rate of 20-25 beats per minute. Animals that can possibly be suffering from circulatory shock can also have elevated heart rates. I suspect that the median pulse for horses with a capillary refill time equal to or less than three seconds will be greater than the median pulse for horses with a capillary refill time greater or equal to three seconds. I also expect there to be variety in each group due to many different reasons. Reasons could include temperature, dietary, laminitis and endotoxemia. Having good feed practices, dietary and parasite management and good health practices all help minimize the chances of a horse producing Colic. I will categorize capillary refill times into two classes. The variable that will stay the same as the pulse.
