Diet type affects viscosity of ileal digesta of dogs and simulated gastric and small intestinal digesta

Journal of Animal Physiology and Animal Nutrition, 2007
SummaryTwo experiments were conducted to determine effects of diet type on viscosity of ileal digesta of dogs and simulated gastric and small intestinal digesta. In experiment 1, three canned and three dry dog foods were surveyed for effects on ileal digesta viscosity. Experiment 2 evaluated the same six diets for effects on simulated gastric and small

Quantification of digesta flow into the caeca

British Poultry Science, 2002
1. A caecal intubation technique was developed to determine the amount of digesta that enters the caeca of fed and feed-deprived chickens. 2. Dry matter intakes per day for control and caecostomised chickens were not significantly different. 3. For fed and feed-deprived roosters, water intake was significantly increased by caecostomy in control birds ...

On the mathematics of digesta flow kinetics

Journal of Theoretical Biology, 1985
A unifying mathematical analysis of the use of compartmental models with and without time lags is given, with particular reference to the use of such models for digesta movement along the gastro-intestinal tract of the ruminant. First the generalized compartmental model without time lags is developed, and then it is shown how discrete time lags may be ...

Digesta Passage Times in the Dugong

Australian Journal of Zoology, 1995
The retention times of particulate digesta were measured in two captive dugongs, Dugong dugon (Muller 1776) using inert plastic markers. The mouth-to-anus retention times (146-166 h) were similar to those of the West Indian manatee, and much longer than those of most other herbivorous mammals. This slow gut passage rate may be explained by the dugong's

An automatic digesta sampler for sheep

Journal of Agricultural Engineering Research, 1983
Abstract An automatic sheep-digesta sampler is described, which has been designed for nutrition and physiology studies including sampling for the measurement of trace elements. The sampler is connected to the sheep by a permanently implanted intestinal re-entrant cannula.

The Physical Characteristics of Digesta

2011
We examine the physics of flow and mixing in the particulate suspensions that constitute digesta. We examine how this changes with alterations in the relative volumes of solid and liquid components as digesta transits the digestive tract. The effects of the size and shape of the component particles and of interactions between them on the rheological ...

Some Generalized Stochastic Compartment Models for Digesta Flow

Biometrics, 1989
Digesta flow models have been based on linear compartment theory that assumes exponential retention times, and on a generalized theory that incorporates nonexponential (Erlang) retention times (Matis, 1987, Journal of Theoretical Biology 124, 371-376).

Forestomach: Control of Digesta Flow

1987
Utilization of roughage diets by ruminants involves complex relationships among diet components, microorganisms in the reticulo-rumen and the animal. Ingesting roughages requires from ruminants to complete an extensive physiological work: the feed particles breakdown.
