COMPLETE REPLACEMENT OF FISH MEAL BY POULTRY BY-PRODUCT MEAL IN PRACTICAL DIETS SUPPLEMENTED WITH COATED AMINO ACIDS FOR PACIFIC WHITE SHRIMP LITOPENAEUS VANNAMEI
摘要
Abstract
A 2 × 6 factorial experiment with two levels of dietary protein (32%and 40%) and six amino acid (AA) treatments were conducted to determine effects of complete replacement of fish meal (FM) with poultry by-product meal (PBM) in diets on a basis of EAAs or EAA+NEAAs on the growth and body composition of Pacific white shrimp over an 8-week feeding trial. Six AA-treated diets were formulated and expressed as diet FM (basal diet), diet PBM, PBM+crystalline EAA, diet PBM+coated EAA, diet PBM+crystalline EAA+crystalline NEAA and diet PBM+coated EAA+coated NEAA, respectively. For each dietary protein level, WGR in groups of PBM+crystalline EAA and PBM+crystalline EAA+crystalline NEAA were higher than that in PBM group (P<0.05). No difference in WGR between group PBM+coated EAA and control groups at 32%dietary protein level (P>0.05) was observed. The WGR in group PBM+crystalline EAA and in group PBM+crystalline EAA+crystalline NEAA was not different (P>0.05), but it was lower than that in group PBM+coated EAA and group PBM+coated EAA+coated NEAA groups (P<0.05). The WGR value in group of PBM+coated EAA was significantly higher than that in group PBM+coated EAA+coated NEAA (P<0.05). Changes in FCR was the opposite of WGR (P<0.05). The shrimp fed the 40%protein diets had higher WGR and body protein content but lower body lipid content (P<0.05) compared to those shrimp fed 32%protein diets. Plasma free AA concentrations of group PBM+coated AA were generally lower than those in group PBM+crystalline AA (P<0.05). There were no differences in muscle AA contents (P>0.05) except glutamate, glycine and proline across dietary treatments (P<0.05). Feeding a diet with PBM+coated EAA can lead to a growth comparable to feeding the basal diet at 32%dietary protein level.关键词
