Abstrakt: The objective of the study was to evaluate the effectiveness of the digital rectal palpation (DRP) technique for early pregnancy diagnosis and to compare the results of experiments I and II in the Red Sokoto goat. Experiment I had 68 goats with 52 does and 16 bucks. Does were divided into prostaglandin F 2 -alpha (PGF 2 α; n = 18), progesterone pessaries (P 4 P; n = 18), and Control (n = 16) groups as oestrus synchronizaton methods. Bucks were used for oestrus detection (n = 6) and breeding (n = 10). Comparative pregnancy diagnosis was carried out on day 21 post-breeding using ultrasonography (US), DRP, progesterone assay (PA), ballottement (BL), and non-return-to-heat (NRH). Experiment II was a repeat but had 51 animals with 42 does and nine bucks; three bucks for oestrus detection and six for breeding. Does were divided into recto-vaginal artificial insemination (AI) by DRP (n = 14), vaginal speculum AI (n = 14), and Control-natural service (n = 14) groups, indicating breeding methods. Oestrus was synchronized with PGF 2 α and pregnancy diagnosis was carried out on day 21 using US, DRP, PA, and NRH. The results for both experiments were similar. Pregnancy rates for PGF 2 α group were 66.2%, 66.7%, 64.8%, 62.1%, and 63.0% for US, DRP, PA, BL, and NRH, respectively; P 4 P had 81.5%, 81.5%, 42.6%, 20.3%, and 42.6% for US, DRP, PA, BL, and NRH, respectively; while Control was 73.6%, 79.2%, 70.9%, 73.6%, and 73.6% for US, DRP, PA, BL, and NRH, respectively. Proportions are significantly (p < .000) different in the P 4 P group. It was concluded that the DRP technique was effective and consistent in early pregnancy diagnosis on day 21 and comparable to US, PA, BL, and non-return-to-oestrus in both experiments in Red Sokoto goat does.
