Online Published on 30 December, 2022. Abstract Present study was carried on six stomach samples from adult apparently healthy Bakerwali goat. Reticulum was spherical and was separated from rumen by rumino-reticular groove ventrally. Mucosa was dark brown in colour having reticular cells of variable shapes. Cells were smaller towards lesser curvature. Mean empty weight of reticulum was 12.95% of the total empty weight of the stomach whereas the capacity was 7.78% of the total volume of the stomach. Histologically, reticulum consisted of tunica mucosa, tunica submucosa, tunica muscularis and tunica serosa. Lamina epithelialis was lined by keratinized stratified squamous epithelium. Lamina muscularis mucosae was present only towards the tip of primary reticular crests. Tunica muscularis had inner circular and outer longitudinal layers of smooth muscle. Number of crests per field, length and width of primary reticular crests were significantly (p<0.05) higher at lesser curvature. Histochemically, stratum corneum showed strong PAS reaction, stratum granulosum showed strong reaction for Alcian Blue (pH 2.5). Distribution of glycogen was moderate in the layers of lamina epithelialis mucosae except stratum corneum. Lamina epithelialis mucosae and tunica muscularis showed strong reaction for basic proteins. Stratum corneum showed moderate reaction for lipids. Floor of reticular groove at the level of reticulo-omasal opening presented papillae resembling the claws of bird. Entire reticular groove was lined by stratified squamous keratinized epithelium. Lamina muscularis mucosae was incomplete and seen mainly in the lips of reticular groove. Floor of groove had transverse smooth muscle fibers whereas lips contained thick longitudinal smooth muscle fibers. Highlights • The mucosa of the reticulum was dark brown and formed of honeycomb cells which were smaller near lesser curvature • Histologically, lamina muscularis mucosae was present only at the tip of primary reticular crests • Lamina muscularis mucosae was incomplete and seen mainly in the lips of reticular groove.
