Potential Usefulness of Meat and Bone Meal and Poultry By-Products Meal in Diets for Gibel Carp (Carassius gibelio)
Title: Potential Usefulness of Meat and Bone Meal and Poultry By-Products Meal in Diets for Gibel Carp (Carassius gibelio)
Principle Investigator: Shouqi Xie
Year: 2001
Objective: The objective of this study was designed to investigate the effect of replacement of fish meal by MBM or PBM on the growth and feed utilization of gibel carp and to observe if the inclusion of MBM could improve the quality of soybean meal based diet.
Lay Summary/Industry Summary: The present study showed that decreased dietary fish meal protein resulted lower growth rate and it can help to decrease ammonia excretion. 6% replacement of fish meal protein by meat and bone meal (or poultry by product meal) protein decreased growth and feed utilization. High inclusion of meant and bone meal (10%) or poultry by-product meal (8%) could make the fish similar growth as soybean meal based diet. The use of MBM and PBM can help to decrease ammonia excretion of fish. Supplemental lysine and methionine did not improve the diet quality. In the diets containing less than 15% fish meal, inclusion of meat and bone meal can replace 10% fish meal without negative effect on growth and feed utilization.
Scientific Abstract: Two growth trials were conducted in a semi-recirculation system to investigate the effect of inclusion of meat and bone meal (MBM) and poultry by-product meal (PBM) on the growth and feed utilization of gibe] carp (Carassius gibelio). All diets were formulated to be isonitrogenous and isoenergetic based on apparent digestibility. The results showed that decreased dietary fish meal protein resulted in lower growth rate and the use of MBM and PBM can help to decrease ammonia excretion. Supplemental lysine and methionine did not improve the diet quality. Inclusion of MBM can replace 10% fish meal without negative effect on growth and feed utilization. Inclusion of MBM can replace 10% fish meal without negative effect on growth and feed utilization.
