I'm guessing but no fetus takes in food through the mouth, so there will be nothing in the stomach. A fetus gets nutrients from the mother's blood via the the placenta and umbilical cord.

Fetal pigs are typically obtained from companies that specialize in supplying educational specimens for dissection in classroom settings. These companies work with facilities that process pigs for food consumption, and they obtain the fetal pigs as a byproduct of that process. The fetal pigs used for dissection are typically sourced from pigs that have been raised for food production.
The alimentary canal of fetal pigs consists of the mouth, esophagus, stomach, small intestine (duodenum, jejunum, ileum), large intestine (cecum, colon, rectum), and anus. These structures play a role in the digestion and absorption of nutrients, with some modifications present in fetal pigs compared to adult pigs for fetal development and nutrient absorption during early stages of life.
The ridges are called rugae. They provide the stomach with more surface area for food. When food enters the stomach, these wrinkles expand and become stretched out. The purpose is to allow it to expand. This therefore allows expansion in volume of the pig.

In fetal pigs, the pancreas is a soft, elongated organ located near the duodenum. It is pinkish in color and has lobes that are not easily distinguished. The pancreas in fetal pigs is small compared to adult pigs and is still developing.
In fetal pigs, the tongue is responsible for manipulating food for swallowing, aiding in the taste sensation, and executing movements for vocalization or communication with other pigs.
The shape of a fetal pigs kidney is oval. -knowing this from just doing fetal pig exam
Fetal pigs are found in a structure called a uterine horn. It is the point where the uterus and the uterine tubes meet.
