abstract
A study was carried out on sperms biometry in local Jaipur area rams. Twenty two (22 No.) mature rams of 2.8-4.4 years old and 32-40 Kg live body weight were used in this study. Semen collection was performed by using artificial vagina. Semen samples were evaluated immediately after collection. Semen volume and color, mass and individual sperms motility, live and abnormal sperms as well as sperms concentration were estimated. Sperms biometry calculated by using phase contrast microscope and occulo-micrometer lens. Semen biometry means which estimated in this study were; sperms head length 9.52± 1.2 micron, sperms head width 5.12± 2.5 micron, acrosome length 6.09 ± 2.4 micron, head base width 2.44 ± 1.8 micron, midpiece length 11.82 ± 3.6, midpice width 2.31 ± 0.8 micron, tail length 50.46 ± 2.1 micron.
