Effect of Supplementation of Glutathione and α-Tocopherol in Tris and Skim Milk Based Extenders on Motility Parameters of Ram Semen at Refrigeration Temperature

Semen Characteristics of NARI Suwarna Rams during Breeding (Winter) and Non-breeding (Summer) Seasons

“…These findings are in line with studies of Cárdenas-Gallegos et al, (2012) and Benmoula et al, (2017)reporting no seasonality for semen volume, wave motion and individual motility in different breeds of rams. Further, the observed colour of semen as creamy white was in agreement with earlier reports for NARI Suwarna ram semen by Kaimal (2015), Kadaganchi (2017), Jasrotia (2018) and Muniyappanavar (2019) as creamy to creamy white colour.…”

“…Hence, it is concluded that NARI Suwarna rams can produce equally good quality semen in winter as well as summer seasons. (Kadaganchi 2017;Jasrotia 2018;Muniyappanavar et al, 2020) but did not study seasonal variability of these characters which may hold the key in the ability to preserve its semen for longer durations so that it can be used for upgradation or crossbreeding of local sheep to improve their reproductive efficiency. The studies on seasonal changes in the seminal quality of Indian sheep breeds in general and NARI Suwarna rams in particular are scarce.…”
