Chronological changes in postprandial blood glucose level of Labeo rohita (Hamilton, 1822) fed with formulated diet

In general, fish is considered as a natural diabetic animal. In order to understand how the feed is metabolized to glucose and the time duration for its complete uptake from blood, a study was conducted to estimate the pre and postprandial blood glucose level in Labeo rohita, at two-hour intervals of both fasting and fed state. The blood glucose levels of four replicates at every time point were estimated using glucose oxidase method. The pre-prandial/fasting blood glucose level was found to be in the range of 10–18 mg/dl. Whereas, two hours post-prandially the blood glucose level had got increased and estimated to be varying between 46–88 mg/dl, which was maximum. Also, it was observed that the sugar levels got reduced back to normal/fasting state after about 10hrs. Time period shows significant inverse relationship with blood glucose level (p<0.05). These results will help in establishing and managing a proper feeding schedule for rohu.
