EFFECT OF RESTRICTED FEEDING OF PROTEIN LEVEL ON DIGESTIVE ENZYME ACTIVITY AND HISTOLOGICAL CHANGES IN LABEO ROHITA (HAMILTON) FINGERLINGS

To understand the applicability of restricted feeding in the fingerlings of the Indian major carp. rohu, Labeo rohita, an 60-day feeding experiment was conducted in the laboratory involving alternate day feeding of high and low protein diet, respectively. To support this experiment three experimental isocaloric (401.32 to 410.28 kcal/100g) diets of 30%, 25% and 20% crude protein designated as diet A, diet B and diet C, respectively were prepared, using locally available feed ingredients and three different feeding schedules of high protein diet continuously (diet A-30%). alternate feeding of 1-day diet A followed by 1-day diet B (lA/1B) and alternate feeding of 1-day diet A followed by 1-day diet C (lA/IC) were tested. Overall digestive enzymes activity was reported to be higher in the group fed A/1B) and the lowest was recorded in the group T2 fed A/C but histological there is no significant difference is observed.
