THE OPTIMUM CALORIE PROTEIN RATIO IN THE DIET FOR BLACK CARP FINGERLINGS

Studies were conducted on optimum calorie-protein ratio for blackcarp(Mylopharyngodon piceus) by using purified diet consisting of casein, gelatin,soybean oil, dextrin, cellulose flour. mixed vitamins and minerals. There were fiveprotein levels and five calorie grades at each protein level. The results of the experi-ment indicate that 35-40% protein content, 9. 1 calorie-protein ratio (c/p value) and3185-3640 kcal/kg in formulated diet for black carp fingerlings seem optimum,taking the wieght gain, protein efficiency ratio (PER) and food conversion asevaluation targets after 60 days of feeding experiment.These provided scientific basis ferpractical use. According to the results of the experiment, black carp fingerlings havethe ability to digest carbohydrate such as dextrin. So,it can be considered carbohydrate.is one of useful calorie sources in black carp diet and a component to spare protein.
