Physical and morphological characteristics of Kankrej bull semen

Abstract

Aim: Present investigation was carried out to study the physical characteristics of Kankrej bulls semen by evaluation of various semen parameters from neat semen and at various stages of semen preservation. Materials and Methods:A total of 60 ejaculates, 10 each from 6 mature Kankrej bulls, once in a week for 10 weeks, were collected and analyzed for various semen attributes. Result:The mean values for different seminal attributes were: ejaculate volume 4.84 + 0.01 ml, pH 6.88 + 0.01, mass motility 3.72 + 0.02, sperm concentration 1253.83 + 14.68 million / ml, individual motility 86.15 + 0.30 per cent, live sperm count 90.58 + 0.20 per cent, abnormal sperm count 4.24 + 0.03 per cent and acrosomal integrity 81.17 + 0.11 per cent. The colour of the Kankrej bull semen under the investigation was creamy white. Mean values of ejaculate volume, sperm concentration, live sperm count and acrosomal integrity of semen differed significantly (P < 0.05) among the bulls under investigation. The ejaculate volume was positively correlated with mass motility (+ 0.392) and sperm concentration (+ 0.385) and inversely proportional to the mass motility whereas mass motility positively correlated with volume (+0.392), individual sperm motility (+0.329) and live sperm count (+0.527). Conclusion:It can be concluded that the volume, pH, mass motility and sperm concentration of Kankrej bull semen were well comparable with other breeds of Indian cattle, however higher individual motility, live sperm count, acrosomal integrity and lower abnormal sperm count were recorded in the Kankrej bull semen.

Physical Seminal Attributes of Gir Bull Semen

“…The result got support from similar observations made by Kerur (1971) and Shelke and Dhami (2001)who reported the sperm concentration as 1250 and 1219.44 ± 38.24 million/ml in Gir bulls respectively. Similar values have also been found by various like Mandal et al, (2005), Raju and Rao (1982), Patel and Siddiquee (2013) in Shahiwal, Ongole and Kankeraj bull respectively. Such variations seem to be obvious as production od semen is highly specific traits and is influenced by various gentic and environmental factors.…”

Effect of optimization of the levels of dissolved oxygen in semen extender on physico-morphological attributes and functional membrane integrity of crossbred bull spermatozoa

“…45, 82.50±0.99, 87.08±0.76, 8.89±0.21, 85.60 ±1.04, 82.66± 0.70, respectively. In present study, mean value of mass activity of semen samples was in agreement with findings of some previous works done on bull semen (Patel and Siddiquee, 2013;Kumar and Krupakaran, 2014;Pande et al, 2015) but, higher than as reported by Kumar et al (2015). Average sperm concentration in present study was found to be comparable with some previous reports (Mandal et al, 2005;Patel and Siddiquee, 2013).…”

“…The mean percentage of Individual progressive motility of semen samples was similar to findings of Pande et al (2015). However, higher Individual progressive motility has also been observed by Patel and Siddiquee (2013) and lowers by Kumar and Krupakaran (2014) and Kumar et al (2015). Sperm viability of a semen sample has direct and positive correlations with fertility of a bull.…”

Fresh and post thaw quality characteristics of Holstein Friesian bull semen maintained at semen production unit Quetta Baluchistan, Pakistan

“…The reported results were in contrast to the results of current study. This indicates that the semen from Holstein Friesian bull, freezes in similar pattern to those of other breeds of cattle reared in hot season [27,28]. However, some contradictory reports were reported from different parts of the world.…”
