Biometrical Study on Normal Spleen of Cattle

摘要

This research work was conducted on 104 cattle, 52 from each male and female, slaughtered at different slaughter houses of Hyderabad city. The mean length of spleen of male cattle at the age of 2, 3, 4 and 5 years was 39.09?0.05cm, 44.75?1.67cm, 45.5?4.26cm and 51.5?0.85cm respectively, while that of female was 38.87?0.21, 43.25?2.91, 43.34?1.43 and 45.30?0.68cm respectively. The mean width of spleen of male cattle at the age of 2, 3, 4 and 5 years was 10.25?0.22cm, 10.85?0.11cm, 11.92?0.41cm and 12.66?0.27cm respectively. While that of female was 10.58?0.14cm, 10.82?0.31, 10.88?0.24cm and 10.96?0.24cm respectively. The mean thickness of male cattle at the age of 2, 3, 4 and 5 years was 1.85?0.02cm, 1.9?0.14cm, 2.2?0.35cm and 2.26?0.07cm respectively, while that of female was 1.86?0.14cm, 1.92?0.11cm, 1.93?0.75cm, 2.23?0.10cm respectively. The mean weight of spleen of male cattle at the age of 2, 3, 4 and 5 years was 395.70?9.41g, 401.5?42.91g, 571.75?37.16g and 734.19?29.47g whereas that of female cattle in these groups was 377.05?6.75g, 455.87?5.76g, 518.81?15.93g and 572.73?5.87g respectively. A significant increase in the mean length, thickness and weight of spleen of both sexes of cattle was observed as their age increased. A significant increase in the mean width of spleen of spleen of male cattle was noted as the age of the animal increased, while little increase in the mean width of female cattle was observed as their age advanced which was statistically nonsignificant.
