Abstract

The poultry red mite Dermanyssus gallinae is an obligatory blood sucking ectoparasite. The aim of this study was to investigate effects of Dermanyssus gallinae on nutrient contents of whole carcass and hematological parameters of Japanese quails. A total of 80 quails were separated in two experimental groups as control and infested. Groups were housed in identical rooms. Birds of infested group were infested with Dermanyssus gallinae at 1 week of age. The birds were slaughtered on an age of 6 week. Leukocyte numbers were not significantly different between groups (P=0.3817). However, hematocrit, erythrocyte and hemoglobin levels were significantly lower in infested group (P<0.05). Average lymphocyte ratios of control and infested groups were 77% and 71%, respectively (P=0.0347). Despite lymphocyte ratios, eosinophile ratios were significantly higher in infested quails (P=0.0001). Hot and cold carcass weights of control group were higher than infested group (P≤0.0006). Thawing loss was statistically higher in infested group than control group (P=0.0233). The average dry matter content ratios of carcasses were 37.06% for control and 32.97% for infested (P=0.0006). Crude protein ratio was not significantly different between groups (P=0.3160). As a result, Dermanyssus gallinae has deleterious effects on Japanese quails according to hematological parameters. In addition, findings of carcass characteristics show potential damages of mite infestation on quail meat quality. Keywords: hematology, meat quality, ectoparasite, red mite, quail
