Summary Intrauterine developmental stages of the gastric compartments of the caprine ( Capra hircus ) A chronological and systematic scheme for intrauterine development stages of the composed stomach of caprine is proposed. Twenty one embryos (1.69 cm to 5.90 cm S. C.) and 16 fetuses (5.90 to 35 cm S. C.) for studying morphogenesis, histogenesis and relationships of gastric compartments were used. Six developmental stages were conventionally determined from the most relevant anatomical and histological characteristics. The first four stages are characterized by appearance of the different compartments, their morphological modifications and progressive positional changes until their semi‐final form and relations. The two last stages are characterized by histological differentiation of both the reticulum wall and abomasum mucosa. They can also be recognized by observing the volume relationships between rumen and abomasum. Comparative aspects with bovine and ovine intrauterine development are commented together with considerations concerning the unitary origin of the stomach compartments.
