Global Climate Change and Changes in Disease Distribution: A Review in Retrospect

Abstract

Turkey is an integral part of poultry, provides all essential substances as other meat, has a comparatively low percentage of fat and a high percentage of proteins. The available records on hematology and biochemical profile of turkeys are very scanty. The study has been carried out to measure hematological and biochemical parameters in turkey birds concerning sex. A total of 20 turkeys at the age of 18 to 22 weeks consisting of 10 male and 10 female birds maintaining under existing environmental and feeding management in farm conditions at Nakla Upzilla of Sherpur district were used. Blood samples were collected from wing veins of each bird consistently in the morning hours to avoid diurnal variation. Hematological and biochemical analyzed were done according to standard methods. The result showed that Hb concentration, PCV and TEC values were higher in male turkey than those in female turkeys. The values were statistically significant (p<0.05) between male and female birds.In biochemical data, the serum total protein and serum albumin values were slightly higher in female turkeys than those of male ones but the values were not statistically significant. The serum glucose level was found higher in male than the female. Among the lipid profile, the total cholesterol, triglycerides and LDL-c levels were higher in females than males. The data were statistically significant (p<0.05) except total cholesterol which was not significantly differed. On the other hand, HDL-c values were higher in male turkeys. The mean values of ALT, AST and creatinine in both males and female birds were more or less similar. Although the ALT and AST levels were slightly higher in female birds than males, the values were statistically insignificant. The study concluded that there are variations in hematological parameters and lipid profiles between male and female turkey birds of 18-22 weeks.
