Still-born Fetal Pigs and How Nutrition Plays a Part
Kiera Lee
Introduction
This experiment looks into the progress to of fetal bullshit its being still-born. Pigs suffer up to 50% embryologic and fetal loss during gestation and exhibit the most pure(a) natur wholey occurring intrauterine growth retardation among livestock species (Wu, Bazer, Burghardt, Johnson, Kim, Li, Satterfield, and Spencer). looking at outside sources we see that there is already a high rate of mortality among the pig species. The dissection of the fetal pig in the laboratory is important because pigs and humans have the akin level of metabolism and have similar organs and systems. We looked into the forage of the fetus, and based on the size of the fetus itself and the weight several(prenominal) organs inside of the fetus, predicted that a lack of nutrition ca utilise the fetus to be still born. We hypothesized that the because of the fetuses malnutrition it was still-born.
Materials and Methods
To complete this experiment we used maintain fetal pigs, which were obtained from pregnant pigs that were being slaughtered for food. We first examined our preserved pig externally. We measured the pig, using yarn, from its snout to its back hooves and compared that to 3 other(a) fetal pigs, which were also still-born.

Next we made and incision to the ab cavity, using a scalpel to expose the internal organs. After identifying all of the organs of the fetus body we started to remove the organ that we used for testing. The first we take was the heart. We removed the heart using a scalpel and weighed the heart. We then compared the weight of our pigs heart to threesome other fetal pigs. Second we removed the stomach, using a scalpel also. We weighed the stomach while it was still broad(a) and then we removed the contents of the stomach and weighed the stomach again. These numbers were also compared to the resembling three fetal pigs. Lastly removed the lungs and weighed each lung. We assent the weight of the two lungs and...If you want to get a full essay, order it on our website: Ordercustompaper.com
