This study aims to deduce a baseline data regarding seminal attributes (fresh and post thaw semen) and libido of indigenous Dajal and Cholistani breeding bulls. Data were collected on weekly basis for three months and a total of 138 ejaculates were attained for analyses. Among fresh semen attributes, mass motility was significantly higher for Dajal bulls as compared to Cholistani bulls being 2.7±0.2 and 2.1±0.1, respectively. Dajal proved to bear the brunt of cryopreservation in a better way in terms of percentage of live spermatozoa (14.7±0.2% damage). The values of libido index score, reaction time and Time Lapsed between Two Ejaculates were also significantly higher for Dajal breeding bulls. This preliminary study is the first of its kind, which furnishes baseline data regarding various reproductive attributes of Dajal breeding bulls. It envisions future studies on Dajal bulls with a larger sample size related to effect of age, season, feeding regimen, various types of extenders on semen quality, and assessment of fertility rate in order to attain an enhanced productivity.
