This study was done to find out the effect of seasonal variations on the hematological and blood biochemical parameters of local cattle raised in Maysan Governorate. A number of 40 healthy cows were selected for the study during winter and summer seasons, blood samples were collected in each of the two seasons and were analyzed for some hematological and biochemical parameters. The results in the winter season showed significantly higher values of Mean Corpuscular Volume, glucose, total protein, albumin, globulin, bilirubin and creatinine but lower values of total white blood cells count, differential leukocyte count, hemoglobin concentration, Mean Corpuscular Hemoglobin, Mean Corpuscular Hemoglobin Concentration, AST and ALT than that of the same animals during the summer season. However, no significant differences in the erythrocyte count, haematocrite between the two seasons were observed in the local cattle.

A study was conducted on (35) healthy Frisian cow aged (2-4) years and were grown in farms in Al-zubair region, in Basrah city This study was performed to find the effect of pregnancy on blood serum protein concentration (Total protein, Albumin, Globulin, Globulin fractions (α, β, γ). The result revealed there was significant elevation (P

The present study was conducted to investigate the effects of boldenone undecylenate (BUL) on carcass traits and blood stress parameters in growing male rabbits. A total of 170 male rabbits comprising of three breeds namely New Zealand White (NZW; n=55), Californian (CAL; n=50), and Rex (RX; n=65) were taken for this study. The rabbits of each breed were divided into three groups viz., D0 (control), D1 provided with normal dose of BUL (at 4.4 mg/kg body weight), and D2 provided with BUL (at 8.8 mg/kg bwt). The rabbits were kept under temperature ranged from 28-32 and deg;C during the experimental period. Carcass traits of the rabbits were studied, and the blood parameters were measured by radioimmunoassay. Most of carcass traits, globulin and cholesterol levels in the serum were significantly improved for the injection of BUL at normal dose. Plasma corticosterone levels in normal dose injected rabbits were lowered by 27.21 and 15.25% as compared to controls and double dose, respectively. The effect of interaction between dose and breed was non-significant (P>0.05) on almost all carcass traits and blood parameters. In conclusion, BUL improves all carcass traits in male growing rabbits when injected with normal dose of BUL, with the exception of dressing-out%, and has a significant lowering effect on stress hormone (i.e., corticosterone), and increasing effect on serum total protein, globulin and cholesterol.
