An embryonic gross differentiation study was conducted on the stomach 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 fetuses 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. Camels? stomach was observed to comprise of the voluminous smooth compartment rumen, a relatively small beans shape reticulum and a tubular abomasum at first trimester. At second and third trimester the stomach was found to comprise of a voluminous compartment I (rumen) which is subdivided by a strong muscular pillar into a dorsal smooth part and a ventral coarse part, a relatively small compartment II (reticulum) and a tubiform compartment III (Abomasum). Based on the findings in the study, camels? stomach had little/few similarities with true ruminant in terms of development.
