“…However, in the present study cellulose did not affect the rate of gastric emptying (compared with diet B). This is consistent with studies in rats by Shurpalekar et al (1969). It is thus likely that the increased rate of gastric emptying observed by McCance et al (1953) as a result of eating wholemeal bread was the result of other components of dietary fibre, or of some other constituent of the bread, or perhaps of cellulose in a more coarsely ground form than was used in the present study.…”

1.A technique for measuring gastric emptying in growing pigs by complete removal of digesta through a gastric 2. Four pigs were fitted with gastric cannulas and each was used in three trials. 3. The effects of level of feeding (trial I), cellulose (C), maize-oil (MO) or sucrose (SU) supplementation (trial 2) and the level of water intake (trial 3) on gastric emptying of digesta, dry matter (DM) and nitrogen from a barley-weatings-soya-bean (B) diet were measured during 4 h after the morning feed. 4.In trial 1, pigs were given 0.66,0.83, 1 .OO or 1.17 times their standard level of feeding. As the level of feeding rose, so the weight of digesta, DM and N emptied in the first hour after feeding increased. This trend continued to some extent in the second hour, but no effects of level of feeding were seen in the third and fourth hours. 5.In trial 2, maize-oil addition to the diet significantly reduced the gastric-emptying rate of DM in the second hour after feeding, compared with the rates for diet C. The rate of N emptying was significantly slower for diets MO and SU than for diet C.6. In trial 3 there were no significant effects of water intake level (1.75, 2.50 and 3.25 times the weight of diet) on the rate of DM or N emptying from the stomach. The rate of digesta (and thus of water) emptying in the first hour after feeding increased significantly as the water intake rose.7. It was concluded that because the pattern of gastric emptying was very similar despite large differences in nutritional inputs, an important property of the process appeared to be resilience. cannula is described.A major role of the stomach in the pig is to act as a reservoir of food. It provides the small intestine with a relatively continuous supply of nutrients for digestion during periods lasting several hours, between meals which are usually eaten in a few minutes. This process in turn is a determinant of the time-course of absorption and metabolism of nutrients. It is thus of interest to know whether the pattern of gastric emptying can be modified by nutritional means; any effects found could perhaps provide the basis for manipulation of metabolism and growth.At present little is known about whether changing specific components of the diet modifies the rate of gastric emptying in pigs given meals with a high dry matter (DM) content. The only direct comparisons have been made by Laplace et al. (1981) who found that there were minor differences in the patterns of gastric emptying of digesta, DM, starch and nitrogen from semi-purified diets containing maize or wheat starch together with fish meal or wheat gluten. These authors concluded that gastric emptying did not appear to be a major factor limiting the efficiency of nutrient use in the four diets used. There is no information on whether changes in meal size or the proportions of diet and water may affect gastric emptying in pigs. Furthermore, it is not known whether lipids or hyperosmolar amounts of sugars reduce gastric emptying rates, or whether dietary fibre (in the form of cellulo...

“…The microcrystalline cellulose used in the present study is of very fine particle size (>300 mesh) and could be easily incorporated in the diet without affecting the taste and acceptability. Earlier studies from our laboratory (Narayana Rao and Sundaravalli, 1970;Shurpalekar et al, 1969) have shown that incorporation of this microcrystalline cellulose even to the extent of 20% does not affect the overall nutritional value of the diets or the utilization of protein. Probably incorporation of finely divided cellulose could be advocated for use in the low calorie diets for dietary treatment of obesity.…”

“…Recent work carried out in our laboratories revealed that inclusion of 5 to 20 % of extraneous cellulose in a finely divided form (>300 mesh) in a casein diet did not significantly influence gastric emptying time in adult albino rats and utilization of nitrogen in young weanling rats, as revealed by nitrogen balance studies and net protein utilization determinations (Narayana Rao and Sundaravalli, 1970;Shurpalekar et al, 1969). The present investigation was carried out to determine the effect of inclusion of finely divided cellulose (>300 mesh) in the diet on the body composition and cholesterol metabolism of albino rats.…”

The effect of inclusion of extraneous cellulose on the gastric emptying time in adult albino rats

Abstract: Studies carried out on adult albino rats revealed that inclusion of 5 to 20% of extraneous cellulose in a finely divided form (particle size 40 μ, > 300 mesh) in a 26% casein diet did not significantly influence the gastric emptying time.
