The study was aimed to evaluate the efficacy of injectable progesterone and intravaginal progesteronebased protocols incorporating hCG for oestrus induction in postpartum Malabari goats. The experiment was conducted in 14 Malabari goats on day 60 postpartum. Reproductive performance following the treatment was assessed based on parameters like oestrus response, onset of oestrus, duration of oestrus, time of artificial insemination (AI), and the number of animals conceived. The oestrus response was 100 per cent in both the groups. The mean time taken for the onset of oestrus (53.36 ± 6.78 h-injectable; 41.57 ± 4.99 h-intra vaginal), duration of oestrus (33.36 ± 2.09 h- injectable; 33.71 ± 2.13 h-intra vaginal) and the mean time of AI (69.64 ± 7.09 h-intra vaginal; 56.71 ± 4.18 h- injectable) did not differ significantly between the groups. The conception rate was 71.43 per cent (5/7) and 57.14 per cent (4/7), respectively in injectable and intravaginal progesterone groups with no significant difference between the groups (p>0.05). The study revealed that, both injectable progesterone and intravaginal progesterone protocols were effective in inducing oestrus in postpartum Malabari goats.
