Dietary supplementation with housefly (musca domestica) maggot meal in growing beagles: Hematology, serum biochemistry, immune responses and oxidative damage

Abstract

The present study was carried out to evaluate the hematology, serum biochemistry, immune responses and oxidative damage of growing beagles fed a diet supplemented with housefly (Musca domestica) maggot meal (mm). weanling beagles (initial body weight 2.69 ± 0.17 kg) were fed a control diet (0% mm) or experimental diet (5% mm) for 42 days. the results indicated that the diet supplemented with 5% MM had no significant effects on the hematology and serum biochemistry of growing beagles (p>0.05). meanwhile, neither the serum concentrations of lysozyme and c-reactive protein nor the serum antibody responses to canine distemper virus and canine parvovirus were influenced by dietary MM supplementation (P>0.05). However, dogs in the experimental group had lower serum levels of malondialdehyde and protein carbonyl than those in the control group (P<0.05). These findings demonstrated that MM could be used as an alternative protein source in growing beagles without any adverse effects on hematology, serum biochemistry and immune responses. furthermore, dietary mm could alleviate oxidative damage in growing beagles.
