Effect of Age on Serum Cholesterol and Triglyceride Levels in the Experimental Rats

Abstract

The feeding of stock diet to different ages, four, eight and twelve months of, rats (Sprague – Dawley) showed that serum cholesterol level of 19 female rats was statistically significant difference at 5 % level among three ages 85.42, 112.11, 122.21 mg/dl in four, eight and twelve months rats respectively. In 14 male rats, the results showed that serum cholesterol level was statistically significant difference between four and eight monthed rats whereas there was no significant difference between eight and twelve monthed rats. The result of serum triglyceride level was fluctuate in both male and female rats among four, eigth, twelve months of age. The results of this study indicated that age of the experimental rats may effect on the serum cholesterol level especially in the female rat.
