The purpose of this study was to identify gross morphology, biometric measurement, histological, mineral structural content, and the correlation between them in the spleen of Karadi male lambs. This study was conducted in the Animal Science field, department of Animal Science, College of Agricultural Engineering Sciences, University of Sulaimani. A total of fifteen 15 spleen of Karadi male lambs used in this study. Spleen samples used to histological study and determined some macro mineral concentration. Results indicated the mean value of weight was 46.50 gm and its mean values length, width, and thickness in spleen lamb were 11.07, 6.81, and 1.38 cm, respectively. Results showed a positive correlation between most of the parameters in this study, but; the negative correlation between lamb initial wt. and Ca was r=-0.552, p= 0.098, spleen wt. and Ca was r= 0.104, p= 0.775, spleen length and spleen thickness was r=-0.427, P=0.218, spleen length and P was r= -0.117, p= 0.748, spleen thickness and Na was r = - 0.081, P=0.825, spleen thickness and Ca was r= -0.618, P=0.057, Ca and P was r = -0.496, P=0.145. Also, our result showed spleen gross anatomy (parietal and visceral) surfaces and spleen components (red pulp, white pulp, central artery, trabecular) in spleen karadi male lamb.
