Abstract: Several techniques for pregnancy diagnosis in goats are developed. Some of them are efficient
and applicable in the field, but not enough accurate. Others are outlined with a high precision,
but require equipment and specialised skills. Fifty supposedly Pregnant Maradi Does (PMD)
were purchased and tested for pregnancy using three methods: the abdominal palpation method
(manual method), the A-mode ultrasonography and the B-mode ultrasonography (electronic
methods). Stage of pregnancy and pregnancy parameters such as: foetal age, foetal number and
foetal viability were determined using the ultrasound scanner (B-mode). The PMD were grouped
into: First-Trimester (FT), Second-Trimester (ST), Third-Trimester (TT) and managed on-farm
till eight weeks post-kidding. Pregnancy status prediction reveals that manual method used was
70.0% accurate, pregnancy detector device (A-mode) was 85.0% accurate, while accuracy of
ultrasound scanner (B-mode) machine result was 100.0%. Stage of pregnancy and pregnancy
parameters measured were 100% accurate at post-kidding. The result implies that B-mode
ultrasonography is highly accurate in pregnancy prediction in goats. |
