Effect of Two Dietary Protein Levels on Body Weight and Composition in Channa punctatus (Bloch.) Fingerlings
Öz
Low-protein (33%) and high protein (40%) diets were formulated to feed the fingerlings of Channa punctatus. Seven feeding treatments were maintained and the fingerlings were fed at 3% BW d-l for 45 days. Studies have revealed that regular feeding on low protein (LP) diet resulted in significantly (P<0.05) low growth, while feeding on 1L/3H diets resulted in good growth performance and was equal to the fish fed continuously on high protein (HP) diet. Nutrient retention (SGR, GCE, APD) and FCR values were similar in fingerling fed either continuously on high protein diet or on a feeding schedule consisting of 1L/3H. These studies have indicated the possibility of protein saving without compromising the growth and nutrient retention in C. punctatus. Based on total protein input 12.36% protein can be saved without affecting growth, by adopting the 1L/3H feeding schedule as compared to daily feeding on high protein diet.
