Effects of Fish Meal Replacement with Poultry By-Product Meal on Growth Performance, Feed Utilization, Digestive Enzyme Activities and Antioxidant Capacity of Juvenile Yellow Catfish ( Pelteobagrus fulvidraco)
摘要
Abstract
An 8-week feeding trial was conducted to evaluate the effects of fish meal ( FM) replacement with poultry by-product meal ( PBM) on growth performance, feed utilization, digestive enzyme activities and an-tioxidant capacity of juvenile yellow catfish ( Pelteobagrus fulvidraco) . Six iso-nitrogenous and iso-lipid diets ( crude protein content was 45% and crude lipid content was 10%) were formulated with different levels of PBM, which were supplemented 0, 5. 25%, 10. 51%, 15. 77%, 21. 03% and 31. 54% PBM to replace 0, 10%, 20%, 30%, 40% and 60% FM, respectively. A total of 540 juvenile yellow catfish with an initial body weight of (2.17±0.02) g were randomly divided into 6 groups with 3 replicates per group and 30 yellow cat-fish for each replicate. The results showed that survival ratio ( SR) was not significantly influenced by the re-placement ratio of FM by PBM ( P>0.05) . The weight gain ratio ( WGR) , specific growth rate ( SGR) , feed efficiency ( FE) and protein efficiency ratio ( PER) of yellow catfish were significantly increased when the re-placement ratio of FM by PBM increased from 0 to 20% (P<0.05), and they were significantly decreased while the replacement ratio of FM by PBM increased from 30% to 60% ( P<0. 05 ) . The condition factor ( CF) , intraperitoneal fat ratio ( IPE) and viscerosomtic index ( VSI) of yellow catfish were not significantly influenced by the replacement ratio of FM by PBM (P>0.05). There were no significant differences in the contents of dry matter, crude protein, ash and crude lipid in muscle and whole body among groups ( P>0.05) . The stomach pepsin ( PEP) activity of control group had significantly lower than the other groups ( P<0.05) , the stomach amylase ( AMY) activity was significantly increased when the replacement ratio of FM by PBM more than 10% compared with control group ( P<0.05) , the foregut AMY activity of 10% FM replace group was significantly higher than of control group ( P<0. 05 ) , and the liver AMY activity of 30% FM replace group was significantly higher than that of control group ( P<0.05) . The activity of aspartate aminotransferase ( AST) in serum of all FM replace groups had no significant difference compared with control group ( P>0.05), but the alanine aminotransferase (ALT) activity and triglyceride (TG) and total cholesterol (TC) contents in serum of 30% FM replace group had the highest values, and they were significantly higher than those of control group ( P<0.05) . The liver superoxide dismutase ( SOD) activity reached the highest value in 20% FM replace group, and it was significantly higher than that of control group ( P<0.05) , and the liver ma-londialdehyde ( MDA) content in 40% and 60% FM replace groups was significantly higher than that of control group ( P<0.05) . However, no significant difference was occurred at liver catalase ( CAT) activity among all groups ( P>0.05) . Using WGR as the evaluation index, the optimal replacement ratio of FM with PBM is esti-mated to be 20.84% by broken-line model analysis.关键词
