An Evaluation of Optimal Dietary Protein Requirements of All Parts Chicken Meal for Indian Major Carps (Catla catla, Labeo rohita and Cirhinus mrigala)

Özet

A feeding experiment was conducted for one year with six formulated diets containing all parts chicken meal in threedifferent inclusion levels (25%, 35% and 45%) as APCM I, APCM II, APCM III and Fish meal as Control I, Control II andControl III, to examine the potential of all parts chicken meal as a substitute of fish meal in the diet of Indian major carps inintensive polyculture system. Fingerlings of Catla catla, Labeo rohita and Cirhinus mrigala were fed on experimental diets. Itis evident by the results that growth is highly affected by dietary ingredients and its level of inclusion in diet. With increasinglevel of fishmeal, a noticeable decrease in growth was observed, as Control I, II and III produced 67.3 g, 50.5 g and 39.6 gmean weight gain respectively. While opposite trend of growth was observed with APCM based diet i.e., APCM III (45%inclusion of APCM) produced significantly higher growth with a decreased FCR. The two-way analysis of variance forweight, DFA, SGR and FCR against months showed highly significant relationship in all diets. Except moisture and ash, fishcarcass composition was significantly affected by protein source and its inclusion level.
