Abstract: The aim of this study was to evaluate the features of induced abortion and post-abortion oestrous cycles pattern following treatment with prostaglandin F2α (PGF2α) in Sokoto Red (SR) goats. Twelve apparently healthy goats made up of 6 pregnant and 6 non-pregnant (cycling) does were used for the study. Each doe was given a single intramuscular injection of 7.5 mg PGF2α. All the 6 pregnant does treated with PGF2α aborted within 72.0±12.4 h post-treatment. Of the 6 does that aborted, 5 (83.3%) showed oestrus subsequently while 4 (66.7%) out of the 6 non-pregnant does were induced to oestrus. Time interval to induced oestrus was 129.6±36.1 and 50.0±11.5 h for the aborted and non-pregnant does, respectively. Mean duration of oestrus for the aborted and non-pregnant does was 46.9±9.6 and 38.7±4.3 h, respectively. The first and second post-abortion oestrous cycle lengths were 6.5±0.5 and 12.5±8.5 days, respectively. While the first and second post-treatment cycle lengths in the non-pregnant does was 22.5±1.2 and 21.3±0.3 days, respectively. It is concluded that a single dose of 7.5 mg PGF2α is sufficient to induce abortion and oestrus simultaneously in SR goats. However, the post-abortion cycles are short.
