“…With regard to the mucosa, the transition from an epithelium of ''embryonic type'' (Warner, 1958) toward a stratified epithelium with uniform distribution of stratum basale and stratum granulosum was evident at 53 days (35% gestation). The stratified squamous epithelium observed here was also observed by Ramkirshna and Tiwari (1979).…”

“…However, other authors report the appearance of this stratum at a later stage: in goats, it was noted by Molinari and Jorquera (1988) at 104 days (70% gestation), while in sheep it has been observed by Wardrop (1961) and Del Rio Ortega (1973) only at birth. The stratum corneum has been reported shortly before birth in buffalo (Tiwari and Jamdar, 1970;Panchamukhi and Srivastava, 1979) and in cattle (Warner, 1958;Asari et al, 1981;Vivo et al, 1990).…”

This study sought to chart the ontogenesis of the goat rumen by histomorphometric examination, scanning electron microscopy and immunohistochemical analysis. A total of 140 goat embryos and fetuses were used, from the first stage of prenatal life until birth. The appearance of the rumen from the primitive gastric tube was observed at 35 days of prenatal life (CRL 3 cm, 23% gestation). By 38 days (CRL 4.3 cm CRL, 25% gestation) the ruminal wall comprised three layers: an internal epithelial layer, a middle layer of pluripotential blastemic tissue and an external layer or serosa. Ruminal pillars were visible at 46 days (CRL 6 cm, 30% gestation), and by 76 days (CRL 18 cm, 50% gestation) ruminal papillae were starting to appear. Under scanning electron microscopy, by 50 days (CRL 7.7 cm, 33% gestation) small ruminal papillae were observed protruding from the surface. Finally, neuroendocrine cells (synaptophysin, SYP) were detected at 53 days (CRL 9 cm CRL, 35% gestation), while glial cell markers (glial fibrillary acidic protein-GFAP, and vimentin-VIM) were found at 108 days (CRL 31 cm, 72% gestation) and 39 days (CRL 4.4 cm, 26% gestation), respectively. Neuropeptide Y (NPY) and vasoactive intestinal polypeptide (VIP) were detected immunohistochemically at 113 days (CRL 33 cm, 75% gestation) and 120 days (CRL 35 cm, 80% gestation), respectively. In conclusion, histomorphogenesis of the rumen in goats was similar to that reported in deer, but rather slower than observed for sheep or cattle. Anat Rec, 295:776-785, 2012. V C 2012 Wiley Periodicals, Inc.Key words: Capra hircus; forestomach; histochemistry; histology; prenatal developmentThe goat is among the ruminant species best able to make use of marginal pasturelands (Boyazoglu et al., 2005;Rancourt et al., 2006), and is highly adapted to grazing over a wide range of vegetation (El-Gendy et al., 2010). Browse appears to be an important component of its diet, and it is widely regarded as the best user of poor roughage (Gihad et al., 1980). Morphological analysis of the goat digestive tract has led to its being classed as an intermediate feeder, situated between the concentrate selectors at one extreme and the grass-roughage eaters at the other (Hofmann 1973(Hofmann , 1989.This ability to make use of grazing land is linked to the particular morphology of the ruminant stomach, which comprises four compartments: rumen, reticulum, omasum, and abomasum. The rumen, reticulum and omasum form the forestomach (proventriculus), whose tunica mucosa is lined by a squamous, keratinized stratified epithelium (Ramkrishna and Tiwari, 1979;

“…The forestomach develops from gastric tissue (Lambert, 1948;Lewis, 1915;Pernkopf, 1931;Warner, 1958) and not from the esophagus as previously thought (Sisson and Grossman, 1953, p. 456). Although the abomasum develops first, the rumen soon becomes heavier than the abomasum in the fetus of the lamb (Wallace, 1948) and of the calf (Becker et al, 1951).…”

“…When young ruminants are given access to solid feed as well as to milk, the tissue weight and capacity of the forestomach develop rapidly, whereas the abomasum changes little relative to body weight (Godfrey, 1961a;Kesler et al'., 1951;Tamate, 1957;Tamate et al, 1962a;Wardrop and Coombe, 1960). Stratification of the rumen epithelium begins early in fetal life (45 days) in the bovine (Warner, 1958) and by birth all the layers characterizing the mature epithelium have formed but have not reached adult proportions (Tamate et al, 1962b;Wardrop, 1961a). S a,all papillae are present at birth, but there is no sign of papillary bodies.…”

“…Smith's sug gestion that this development resulted from fermentation of the milk in the rumen is supported by the distinct but ab normal papillary development found by Tamate et al (1962a) when milk was administered directly into the rumen of a young calf. In view of the histological development of the forestomach in pre-natal life (Wardrop, 1961a;Warner, 1958) and the presence of papillae at birth (Tamate et al, 1962a;Wardrop 1961a), it may be concluded that the basic features of the rumen develop independently of nutritional factors.…”

The development of the vagal innervation of the bovine stomach was examined in serial section from 15 embryos ranging from 10 to 20 mm crown-rump length. Models of the gastric epithelium and nerves were made of an 11, 14, and 20 mm embryo. The vagal innervation of the stomach was also examined in six bovine fetuses ranging from 15 to 52 cm in length. The bovine stomach developed from a spindle-shaped primordium at 10 mm to a four-chambered organ at 20 nun. At 11 mm, the right and left vagus extended to a point dorsal to the heart where they divided into dorsal and ventral branches. The ventral branches fused to form the ventral vagal trunk and the dorsal branches fused to form the dorsal vagal trunk. At the 12 to 14 mm stage, both vagal trunks ran along the lesser curvature of the gastric primordium to the level of the developing abomasum. By 20 mm, the principal branches of the vagal trunks found in the adult were established and it became clear that the dorsal and ventral vagal trunks innervated areas of the ruminant stomach roughly comparable to the visceral and parietal (posterior and anterior (NA)) surfaces, respectively, of the simple stomach. The distribution of the vagal trunks in the fetuses was similar to that in the adult. Similarities in the development of the gastric nerves in man and ox were discussed.The bovine stomach in a four-chambered organ which consists of a proventriculus and a glandular stomach (Sisson and Grossman, '53; Nickel and Schummer, '60). The proventriculus is made up of the rumen, reticulum, and omasum, and the glandular stomach of the abomasum. Contrary to earlier accounts of an esophageal origin of the proventriculus, the four compartments of the bovine stomach develop from a spindle-shaped gastric primordium similar to that from which the simple stomach develops (Pernkopf, '3 1; Martin and Schauder, '38; Lambert, '48; Warner, '58). The rumen and reticulum correspond to the fundus and body of the simple stomach, the abomasum to the pyloric part, and the omasum to an outgrowth of the lesser curvature of the primordium. In the adult ox, the rumen is the largest of the four compartments and lies to the left in relation to the other compartments. The right and left surface of the rumen is marked with longitudinal grooves which are connected cranially and caudally by two deep transverse grooves, the cranial and caudal grooves of the rumen. These longitudinal and transverse grooves divide the rumen into dorsal and ventral sacs. The most cranial part of the rumen, AM. J. ANAT.. 121: 121-130.
