Abstract
Abstract The study was undertaken to demonstrate the effect of age, and sex on hematological and biochemical parameters of goat in Libya. A total of 70 healthy animals of diverse age and sex were selected randomly from two different areas in Libya. The blood samples were collected from the jugular vein of animals for blood analysis. Statistical analysis was applied by using SPSS Statistics software version 25 to calculate the minimum and maximum values to determine the mean, standard deviation of the mean, and the p value. The results revealed that there are no statistically significant differences between the means of hematological parameters for the gender of goats (p -value > 0.10). Regarding the effect of age, the results of blood hematology revealed that the mean values of WBC (12.46±4.90×103 /µL, 14.37±4.23×103 /µL), lymphocyte (6.34±2.91×103 /µL, 8.04±2.34×103 /µL) counts and lymphocytes percentage (46.78±14.04%, 57.89±57.89%) were significantly different (p -value < 0. 05) in young and adult goats respectively. No significant variations (p -value > 0.10) were observed in the erythrocyte parameters among young and adult goat. There were significant effects (p < 0.01) of age on biochemical parameters of goat. The 10- 16-month-old goats showed significantly lower blood protein (p < 0.01), albumin (p < 0.001), cholesterol (p < 0.05), HDL (p < 0.01), creatinine (p < 0.001), and calcium (p < 0.01) than did adult goats, while the other determined enzymes (AST, ALP, LDH), bilirubin, glucose, urea, lipids, and electrolytes did not change statistically. This work showed that age, and sex affected significantly hematological and biochemical parameters in local goats raised in Libya.
