Abstract:
A total of 60 does aged between 2-5 years located at Livestock Research Station, Mahabubnagar were selected and divided into 3 equal groups. First group were not treated with any protocol and considered as control group. Second group (GPG/Ovsynch) were treated with GnRH on day 0, PGF2α on day 7 and GnRH on day 9 intramuscularly. Third group (PPG/double PGF2α with GnRH) were treated with PGF2α on day 0, 7 and GnRH on day 9 intramuscularly. Estrus response was observed from 9th to 14th day after GnRH treatment. The average time taken for onset of estrus was 124±4.59, 52.37±3.59 and 65.25±3.58 hours in control, GPG and PPG group respectively. The duration of estrus in control, GPG and PPG groups were 28.30±2.22, 38.25±1.76 and 45.38±1.75 hours respectively. The average estrus response rate was 50%, 80% and 80% in control, GPG and PPG group respectively. Conception rates were 50%, 80% and 80% respectively in control, GPG and PPG group. Kidding rate was 80% in control group and 100% in GPG and PPG groups. The average litter size in control, GPG and PPG were 1.25, 1.31 and 1.37 while, twinning percentage was 25%, 31.2% and 37.5% respectively. The present study revealed that the GPG and PPG protocols were equally effective in inducing estrus response, early onset of estrus and higher conception rates when compared to control group.
