Fortification Needs of PGF2Α with Bypass Fat, Minerals and Vitamins for Treatment of Silent Oestrus in Crossbred Cows

“…Available literature revealed very little information on nutritional fortification need of PGF 2 α treatment in the management of silent oestrus in cattle. A good amount of information was available on the efficacy of single or double injection of PGF 2 α for the treatment of silent oestrus in cattle from India (Agarwal and Shankar, 1997;Honparkhe et al, 2008;Sahatpure and Patil, 2008;Kumar et al, 2011 andVenkata Ramana et al, 2013) as well as abroad (Wenkoff, 1978;Kaneda et al, 1981;Mialot et al, 1999;Zeuh et al, 2014 andJamsawat et al, 2015). Sahatpure and Patil (2008) obtained 100.00 per cent oestrus response in buffaloes and cattle respectively.…”

“…Venkata Ramana et al, (2013) reported 81.80 per cent oestrus response and 67.00± 0.26 per cent conception rate in silent oestrous cows using double injection of PGF 2 α given at 12 days interval which was similar to the finding obtained in the present study. Wenkoff (1978) from Canada, Kaneda et al, (1981) from Japan and Mialot et al, (1999) from France. All these reports indicated that post treatment oestrus interval in silent oestrous cows following PGF 2 α treatment ranged from 2-5 days.…”
