Comparative gastric morphometry of Muong indigenous and Vietnamese wild pigs.

Trang PH, Ooi PT, Zuki AB, Noordin MM - ScientificWorldJournal (2012)

Bottom Line: The result indicated that the stomach of the Vietnamese wild pig is broader with a bigger capacity and greater proportion of proper gastric glands.On the other hand, the thicker (P < 0.05) submucosa in the Vietnamese wild pig is attributed to the presence of numerous loose connective tissues, abundant blood vessels, adipose tissues and nerve plexus.In conclusion, adaptations found in the Vietnamese wild pig indicated that this breed is equipped with a bigger and effectively functional stomach to suit its digestive physiology and immunity in the wild.

ABSTRACT
It is hypothesized that despite sharing a similar habitat, the Muong indigenous and Vietnamese wild pigs may reveal different gastric morphology. Due to the protective nature of procuring these pigs, a total of 12 Muong indigenous pigs and nine Vietnamese wild pigs stomach collected post mortem were analysed for selected biometric parameters and histology. The result indicated that the stomach of the Vietnamese wild pig is broader with a bigger capacity and greater proportion of proper gastric glands. Interestingly, the stomach mass correlated well with live body weight in both breeds apart from possessing similar histomorphometry of the gastric gland regions. On the other hand, the thicker (P < 0.05) submucosa in the Vietnamese wild pig is attributed to the presence of numerous loose connective tissues, abundant blood vessels, adipose tissues and nerve plexus. The appearance of lymphoid follicles underneath the tubular gastric glands in the Vietnamese wild pig exceeded that of Muong indigenous pigs. This finding suggested that the difference in feeding behavior as well as immunity. In conclusion, adaptations found in the Vietnamese wild pig indicated that this breed is equipped with a bigger and effectively functional stomach to suit its digestive physiology and immunity in the wild.

Photograph of the intact stomach at post mortem of the (a) Muong indigenous and (b) The Vietnamese wild pigs. Note the mark differences in terms of shape where it is much more circumscribed in (b). In general, the shape of the stomach of the Muong pig closely resembles that of the domestic pig.

Note the mark differences in terms of shape where it is much more circumscribed in (b). In general, the shape of the stomach of the Muong pig closely resembles that of the domestic pig.

Mentions: Figure 1 shows the gross morphology of the stomach where the shape of the Vietnamese wild pig was much more circumscribed. Furthermore, its minor curvature was much longer and obtusely-angled than that of the Muong indigenous pig. However, the pyloric part of the Muong indigenous pig was slender and its terminal portion was closer to the esophageal sphincter and resembled that of the domestic pig.
