Abstract


A Biometrical study was conducted on the digestive tract of 35 foetuses of the one-humped camel collected from the Sokoto metropolitan abattoir, over a period of five months at different gestational ages. The approximate age of the foetuses was estimated from the crown vertebral rump length (CVRL) and samples were categorised into first, second and third trimester. The mean body weight of the foetus at first, second third trimester ranged from 1.40 ± 0.06 kg, 6.10 ± 0.05 kg and 17.87 ± 0.6 kg respectively. The mean weights of the entire digestive system at first, second and third trimester were 0.80 ± 0.07 kg, 2.13 ± 0.04 kg and 4.86 ± 0.08 kg respectively. The mean weights of the digestive tract at first, second and third trimester were 0.53 ± 0.07 kg, 1.03 ± 0.05 and 2.43 ± 0.07 kg respectively. The small intestine at first trimester were found not to have any clear demarcation to show duodenum, jejunum and ileum; the entire small intestine was found to be 76.00 ± 3.00 cm at first trimester and showed clear demarcation at second and third trimesters.. The mean volumes of the entire stomach (rumen, reticular and abomasum) ranged from 136.67 ± 8.30 cm3 at first trimester to 353.33 ± 6.50 cm3 at third trimester. It was observed that there was increase in body weight, organ weight and individual segment of the digestive tract of the fetuses with advancement in gestation period. A geometrical increase in length and diameter of the various segments of the digestive tract showed a significant difference (P≤ 0.05) with advancement in gestational period.
