BookPublisher: 1989Subject(s): Department of TheriogenologyDDC classification: 1126,T Dissertation note: Thirty five Nili-Ravi buffalo bulls stationed at Semen Production Unit Qadirabad were selected for the subject study. All the bulls were normal and regular donar of semen at the station. They were splitted into ten groups according to their age. Each group was carrying three to four animals. A total of 560 ejaculates were collected. Senility pattern was represented by evaluating volume, mass motility, concentration, sperm abnormality, dead/live percentage and reaction time. The data on all these parameters was collected and statistically analyzed to investigate the effect of advancing age on various seminal characteristics and reaction time in buffalo bull.
Statistically, a significant difference (P < 0.05) was noticed for all the parameters among bulls of different age groups. Maximum ejaculate volume, sperm abnormality, percentage of dead spermatozoa and reaction time were observed in age groups IX and X. Minimum ejaculate volume, percentage of dead sperms and reaction .time were observed in age group I. Mass motility and sperm concentration were maximum in age group IV while minimum in age group IX. Minimum sperm abnormality was found in age group III.
