A significant difference was observed in the Libido and mating behaviour indices with in the breeds and within the age groups i.e. 86.99 ± 1.25 Vs. 83.55 ± 3.89 (Group I Vs. II), 82.99 ± 3.17 Vs. 79.44 + 0.49 (group III Vs. IV) and 85.83 ± 0.83 Vs. 84.84 ± 3.69 (group I Vs. II) 81.79 + 2.00 Vs. 84.09 ± 1.04 (group III Vs. IV) where as a significant difference was observed in the volume of ejaculates, Percentage of live/dead spermatozoa, percentage of tail and mid piece abnormalities between the bucks of all the four groups i.e., 0.98 ml ±Vs. 1.02 ml ± 0.05 (group I Vs. II), 1.2 ml ± 0.04 Vs. 1.25 ml ± 0.09 (grouplll Vs. IV) and 5.14% + 0.37 Vs. 3.98 ± 0.29 kind 6.15 ± 0.45 Vs.4.32 ± 0.42 respectively.
Where as, for mid piece abnormalities it was 7.01 ± 0.24 Vs. 1.48 ± 0.16 and 6.01% + 0.2 Vs. 1.32 ± 0.9 respectively. A highly significant difference was recorded for sperm cell concentration per ml and the percentage of total morphologically abnormal spermatozoa within the breed and within the age groups i.e., 2903.83 X io6 ± 24.35 Vs. 3829.03 X io6 ± 40.22 (group I Vs. II) and 2992.34 X 106 ± 26.83 Vs. 3776.74 X 1o6 ± 39.73 (group III Vs. IV) and 15.97 ± 0.74 Vs. 4.74 ± 0.29 (group I Vs. II), 16.98$ + 0.8 Vs. 3.95 ± 0.25 (group III Vs. IV). A non-significant difference was found in mass motility, pH, percentage of head abnormalities and percentage of presence of plasma droplet.
