Gastric emptying of four liquid meals in pony foals.
Abstract: Water, saline and a saline/Intralipid mixture (lipid concentration 1.25 per cent) emptied very rapidly from the stomach in neonatal pony foals, and obeyed an apparently exponential pattern. Cisapride did not significantly modify the emptying of the saline/Intralipid mixture. Equine milk emptied more slowly. The data indicated that the lipid component of milk was not an important factor. Milk caused deviation from an exponential pattern in two of four foals: an initial lag phase appeared, which could represent a phase of intragastric processing. However, the rate was still rapid compared with results from human infants.

Summary

The research article studies and compares how quickly different liquids, including water, saline, saline/Intralipid mixture, and equine milk, empty from the stomach of neonatal pony foals. The findings suggest that the lipid component of milk doesn’t significantly impact the rate of gastric emptying and the speed of this process is fairly rapid compared to human infants.
Investigation of Liquid Meal Gastric Emptying in Pony Foals
- The researchers tested four different types of liquid meals- water, saline, a saline/Intralipid mixture, and equine milk- to analyze their gastric emptying rates in neonatal pony foals.
- Most of the tested liquids showed a rapid and apparently exponential pattern of leaving the stomach.
- In particular, water, saline, and the saline/Intralipid mixture were found to empty at an especially fast rate, irrespective of the lipid content included in the Intralipid mixture.
Impact of Cisapride and Lipid component in Gastric Emptying
- The study also found that adding Cisapride, a motility drug, did not significantly alter the stomach-empting rate of the saline/Intralipid mixture; this implies that Cisapride may not influence gastric emptying rates in neonatal pony foals.
- The study discovered that the lipid component of milk does not seem to play a significant role in influencing the gastric emptying rate in pony foals.
Different Gastric Emptying Pattern for Equine Milk
- Equine milk, in contrast, took more time to empty from the foals’ stomachs. This slower rate could be influenced by factors within the milk other than the lipid content, hence pointing towards the need for further investigation.
- The data also showed that gastric emptying of milk did not follow an exponential pattern in two out of four subjects. The initial lag phase that appeared might suggest a period of intragastric processing is needed for milk.
Comparative Study with Human Infants
- As compared to the gastric emptying rate in human infants, pony foals had a comparatively more rapid rate. This difference could have physiological significance and calls for further studies to investigate the reasons behind it.
In summary, this research provides valuable insight into how the neonatal pony foals’ stomach processes different liquids, the influence of certain drugs and the lipid component on gastric emptying rate, and how this compares to human infants. Further investigation is required to fully comprehend these findings and their implications
