Examination the strain and sex effect on blood serum biochemical parameters and growth traits of quail

Many of blood serum biochemical parameters are associated with resistance to disease, meat quality and performance traits, and can be useful in determining animal health status. The aim of this study was to investigate the effect of strain and sex on growth traits and blood serum biochemical parameters of quail. For this purpose, a number of one-day-old chicks from each quail strain (125 Wild, 159 Italian speckled, 58 Scarlet, 56 Tuxedo, 81 English white, 92 A and M Texas and 57 White Button), were used. The chicks were weighed weekly until 42 day of age. At 35 day of age, 10 birds (5 male and 5 female) were slaughtered from each strain, and their blood serum was separated. The evaluation of blood serum biochemical parameters including total protein, albumin, globulin, glucose, cholesterol, triglyceride, uric acid, calcium, phosphorus, aspartate aminotransferase (AST) and alkaline phosphatase (ALP) enzymes parameters was conducted using autoanalyzer apparatus. The growth traits and blood serum biochemical parameters data were analyzed and compared with R comuter software among strains and sex levels. The effect of sex on body weight at 42 day of age, body weight gain in sixth weeks, calcium, globulin and AST enzyme was significant and strain had a significant effect on all growth traits, cholesterol, triglyceride and phosphorus (P <0.05). All growth traits and blood serum biochemical parameters (with the exception of uric acid and AST enzyme concentrations) were higher in female quails than those of males.
