Real Time Ultrasonography for Determining Viable Foetal Numbers in Goats


DOI:Coming soon...

Abstract:

Twenty-five (25) does in dorsal recumbency were scanned by 3.5 MHz transabdominal sector transducer. Each doe was scanned separately by tilting the doe in right and left side. All the animals were scanned twice between 37-119 days post breeding. One goat showed foetal resorption on its second scan so only 24 goats were considered for calculation of litter size. There was non-significant difference (P = 0.7427, t 0.01 =0.332) between actual and sonographically observed values of litter size and the correlation coefficient between the two was 0.725 (P< 0.01) which is positive and highly significant. The accuracy of detecting single fetus was
83.33% (10/12); twins was 80% (8/10) and triplets was 50% (1/2). In total 37 kids were born viz 12 singles, 11 twins and 1 triplet to 24 goats. The average actual litter size of goats was 1.54±0.120 kids while as by ultrasound it was 1.6 ± 0.129. It was concluded that real-time transabdominal ultrasonography is accurate and practical method for predicting foetal numbers and foetal viability in goats.
