Effect of Partial Replacement of Fish Meal by Poultry By-Product Meal or Pork Meat Powder on Growth Performance, Feed Utilization and Serum Biochemical Indexes of Pacific White Shrimp ( Litopenaeus vannamei)
摘要
Abstract
An 8-week feeding trail was conducted to evaluate the effects of partial replacement of fish meal by poultry by-product meal ( PBM) or pork meat powder ( PMP) on growth performance, feed utilization and se-rum biochemical indexes of Pacific white shrimp ( Litopenaeus vannamei) . Seven isonitrogenous and isolipidic practical diets (40. 0% crude protein and 8. 0% crude lipid) were formulated, and the diet contained 30%brown fish meal was used as control diet. PBM and PMP were used to replace 25% ( named P25 and M25, re-spectively) , 50% ( named P50 and M50, respectively) and 75% brown fish meal ( named P75 and M75, re-spectively) , respectively. A total of 840 Pacific white shrimp with an average initial body weight about 3.40 g were randomly allocated to 7 groups with 3 replicates per group and 40 shrimp per replicate. The results showed as follows: compared with control group, the weight gain rate ( WGR) and specific gain rete ( SGR) in P25 and P50 groups had no significant differences ( P>0.05) , but those in P75 group were significantly decreased (P<0.05); compared with control group, the WGR and SGR in M25 group had no significant differences (P>0.05), but those in M50 and M75 groups were significantly decreased (P<0.05). However, no signifi-cant differences in survival ratio ( SR) , feed efficiency ( FE) , protein efficiency ratio ( PER) and hepatopan-creas somatic index ( HSI) were observed among all groups ( P>0.05) . There were no significant differences in the contents of whole body moisture, crude protein and ash among all groups (P>0.05), but the whole body crude lipid content in control group was significantly higher than that in other groups (P<0.05). Mean-while, the contents of serum high density lipoprotein ( HDL) , low density lipoprotein ( LDL) , total protein ( TP); total cholesterol ( TC) , triglyceride ( TG) , total protein ( TP) , glucose ( GLU) and albumin ( ALB) were not significantly affected by the PBM or PMP to substitute different proportion of fish meal (P>0.05). These results demonstrate that less than 50% fish meal can be replaced by PBM and less than 25% fish meal can be replaced by PMP in the Pacific white shrimp diet (i.e., the PBM and PMP add no more than 16.12%and 8.09%, respectively) , and the utilization ratio of PBM for Pacific white shrimp is better than PMP.关键词
