Physical and morphological characteristics of Frieswal bull semen

Abstract

The present investigation was carried out to study the semen characteristics of Frieswal bulls. In the present investigation a total of 181 ejaculates seminal collected from six bulls were studied and out of these 82.30 per cent were creamy in colour. The density of Frieswal bulls’ semen was found to be thick (93.92%). The overall mean ejaculate volume (ml), individual motility (%), sperm concentration (millions/ml), live sperms (%) and Hypo-osmotic swelling (HOS) positive spermatozoa in neat semen of Frieswal bulls were 5.60±0.16, 60.39±0.04, 1076.1±32.56, 78.93±0.004 and 73.76±0.47, respectively. The differences in mean values of ejaculated semen volume, sperm concentration, live sperm count and progressive motility of semen were highly significant (P
