Abstract

Objective: Optimizing reproductive efficiency in terms of estrus induction and production performance using
simplified hormonal interventions at farmers’ field conditions.
Method: The present study was planned for optimizing reproductive efficiency using four different easily available
hormonal agents with simplified protocols at farmers’ field. A total of 116 female pigs were used in the study.
Hormonal protocols I, II, III and IV using GnRH+(PMSG+hCG), (PMSG+hCG), PMSG alone and prepared
progesterone gel respectively were used for estrus induction in gilts and sows.
Results: The estrus induction rate in protocol I, II, III and IV was 77.77%, 81.36%, 78.57% and 50% respectively.
The corresponding figures for interval (hrs) of heat exhibition from hormonal administration (121.33 ± 4.93, 121.54
± 3.60, 78.52 ± 4.52 and 192 ± 24), conception rate (%) (72.22%, 81.25%, 68.18% and 33.33%), farrowing rate
(55.55%, 68.29%, 68.18% and 33.33 %), total litter size at birth (7.2 ± 0.64, 7.90 ± 0.47, 8.90 ± 0.47 and 7.00 ±
0) and hormonal cost (Rs.) per animal (570, 335, 280 and 250) were respectively. The easier to use protocol was III
followed by II, I and IV.
Conclusion: It was found that protocol II and III are effective and easier which can be used for optimizing
reproductive efficiency in pigs at farmers’ field.
