Observations on the Motility of the Small Intestine in Sheep
نویسنده
چکیده
Intestinal motility was studied in two sheep by electronically recording pressure changes using open-ended p.v.c. tubes placed in the lumen of the intestine and connected to pressure transducers. Flow in the duodenum and ileum was studied concurrently with motility. Both duodenum and ileum showed two types of activity, one progressive and associated with a flow of digesta, and the other localized and not associated with flow. Changes in diet markedly affected intestinal motility. Increasing faecal output was associated with a change in the duodenum from predominantly non-propulsive to propulsive activity, and with an increase in both types of activity in the ileum. Eating stimulated propulsive activity in the duodenum, but was associated with some reduction in both types of activity in the ileum.

Mechanical behavior measurement of the sheep small intestine using experimental tests
Background: There is no consistent data on the mechanical properties of sheep intestine. OBJECTIVES: We performed a series of biaxial strain measurement experiments and extracted the constitutive model to describe the mechanical characteristics of the sheep intestinal tissue. METHODS: Eleven specimens were obtained freshly from sacrificed sheep and the planar biaxial tests were performed on th...

The prevalence of the latent form of sheep abomasal phytobezoariasis and the effect of husbandry management on this condition were determined in a survey in and industrial abattoir in Urmia from June 2005 to July 2006. The effect of different age groups and seasons on the prevalence of sheep abomasal phytobezoariasis was also determined. Furthermore, the histological changes in the affected abo...
