Effect of various factors in blood parameters of laying hens in cages indoor grown in Afyonkarahisar

This study was carried out in five hundred Hy Line breed chickens at the 60 days age breeding in Afyonkarahisar Province. This study was done during the winter season when the outside temperature was 13 ° C, while the average indoor temperature of the shelters was 23°C. Clinical, hematological and blood biochemical parameters were measured in chickens that constituted the study material. Clinically; body temperature (T), respiration (R) and heart rates (P) were measured. In the hematological examinations; formula leukocyte counts were performed with erythrocyte (RBC), total leukocyte (WBC), hemoglobin (HB), hematocrit (HCT), mean corpuscular volume (MCV), mean erythrocyte hemoglobin (MCH) and mean hemoglobin concentration (MCHC). In the blood biochemical examinations; serum aspartate aminotransferase (AST), serum gamma-glutamyltransferase (GGT), ornithine carbamoyltransferase (OCT), serum lactate dehydrogenase (LDH), serum sorbitol dehydrogenase (SDH) and creatine phosphokinase (CPK), total protein (TP), Albumin (ALB), Glucose (GLU), Total and Indirect Bilirubin (TB and IB), Total Cholesterol (TCOL), High Density Lipoprotein (HDL) and Low Density Lipoprotein (LDL) levels were determined. At the end of the study; it has been observed that all of the measured parameters differ from the results obtained from earlier studies, although those within the normal limits. The probable cause of this variability was linked to changes in race, nutritional and climatic conditions. The results obtained from the study were the first to examined clinical, hematological and blood biochemical parameters in chickens breeding in closed cages in Afyonkarahisar Province, and then to reference the field studies of scientific studies and practicing veterinarians to study about this subject.
