Apparent D igestibility of Corn DDGS in Common carp ( Cyprinus carpio ) Diet

1. Shivendra Kumar, Ph.D Apparent Digestibility of Corn DDGS in Common carp (Cyprinuscarpio) Diet Department of Fish Nutrition and Physiology NAIK - Research Institute for Fisheries and Aquaculture (HAKI), Szarvas, Hungary

3. DDGS Essential Amino Acid Lipid Examples: Examples: • Protein: 27-30% • Low Lysine: 0.8 – 0.9% • Low Methionine: 0.5 – 0.6% • Lipid = 5 - 12% • 65% unsaturated fatty acid • 56% linoleic acid (C 18:2) • 8% linolenic acid (C 18:3) • 0.14 % DHA (C 22:6) DDGS Other Nutrients Examples NO Antinutritional factor • Available Phosphorus: 0.75% • Xanthophyll: 3 – 30 mg/kg

Digestibility Equations PROXIMATE COMPOSITION • DDGS Ingredients • Diets • Faecal matter • Yttrium in diet and faeces ADCtest diet (%) = 100 – (100 X {% ifeed / % ifaeces} × {% nfaeces / % nfeed}) Apparent digestibility of the test ingredient calculated (Bureau & Hua, 2006) ADCtest ingr = ADCtest diet + [(ADCtest diet-ADCref diet) X (0.7Dref mix/0.3Dtest ingredient] where D is the % nutrient, “as is” Waiting for proximate analysis report…………..
