Observation Of A Piglet Experiment

People perceive dissecting fetal pigs as being cruel and unnecessary. What they don’t understand is the educational purpose behind it by providing students information to help them better understand not only the functions and structures of the fetal pig but also their own body. These fetal pigs are unharmed and dissecting causes no damage. Concerns about fetal pig dissections will always be a factor of whether or not to perform this task but, there is a reason so many countries and schools continue to educate their students through fetal pig

The procedure consisted of external anatomy. We were asked to exam several characteristics of the unborn pig which includes: determining the age of the fetus by measuring the body length from its snout to the rump, examine the amount of hair on body, examine the lips, nostrils, ears, eyes, feet, chest, stomach, nipples and sexual organs. The procedure also consisted of internal anatomy which includes the oral cavity, digestive system, circulatory system, respiratory system and urogenital system.

All of the incision were preformed very careful and slow. We tried not to rupture the pig, but it very difficult. The equipment that was given was handy, however, they were not comfortable in our hands. For example, the scissors were too small for our hands and the scalpel was not useful in most of the situations we encountered while dissecting. Although we did not conduct many mini experiments, we took a look at our classmates fetal pig. We watched them as they observed the fetal pig’s brain and uncovered their spinal

The purpose of the fetal pig dissection was to understand the scientific process of dissection and gain hands-on experience of the internal and external anatomy of the fetal pig. In addition to this, the fetal pig dissection helps students better interpret the relative position and sizes of organs, as well relation between organ and organ system.

Pigs are one of the most similar animals to humans, and can be analyzed to learn about the organ systems of the body. Both pigs and humans are mammals, omnivores, furless and featherless, and their fetuses receive nutrients from their mothers through the umbilical cord as they develop (Field). These

During this lab, many procedures needed to be completed. This dissection took a week. The dissection required many steps. This dissection required an understanding of how the body works and what the organs look like. The fetal pig dissection was helpful in learning

Feral pigs are omnivores, preferring succulent green vegetation, fruit, grain, and a wide variety of animal meat including, frogs, reptiles, birds, small mammals; and carrion. They also feed on underground plants such as root, bulbs, corms, and fungi. As a result of fossicking for food. The vast diet of feral pigs can cause severe environmental damage to vegetation. Feral pigs can also cause erosion of soil and damage to the native species of animals and vegetation. The requirement of protein and energy in a pig's diet is very high. This is needed for breeding, successful lactation and growth of young.

Sus scrofa, or the domestic pig is a member of the class Mammalia and the order Artiodactyla. Since we as humans are also a member of class Mammalia, we have a good deal in common biologically with pigs, although we might not like to think so. Since we have a good deal in common, it is very helpful for us to study these animals both anatomically and physiologically. We do this when we test medicines on pigs, perfect surgical procedures on pigs, and even when we used to use pig valves for replacements in human hearts. Thus the pig is a first-rate example of a mammal and the purpose of this lab is to recognize the specific similarities between the pig and ourselves as humans. To accomplish this we

After the 16-day lab, we have seen that many of the piglets decompose completely and some less than others. Our group believed

The first step upon obtaining the pig is to carefully examine the pig to determine its age and

Instinctual Behaviors Social structure -For pigs the hierarchy is part of their social structure it’s formed at social maturity levels and is developed as fast as when they are a week old. Piglets form a teat and it stays the same as long as they are still in the same group together. Usually the largest pig in the group is the domain in the group. If pigs do not know each other they will fight until their remains one big tough pig that bosses the others which is the dominate one in the pen.Reproduction - pigs have a very high reproductive cycle since they can produce more than two litters of piglets a year. Sows female pigs have a heat cycle of twenty-one days you can tell the sow is in heat when they stand still to having pressure on their back and lower back without wanting to get away. That means she is ready and accepts the boar male pig.It's important to know the signs of when the pigs are in the state of heat and their behavior. It usually takes three to five minutes then separate the pigs and repeat in twelve to twenty-four hours.Mothering - Sows behavior is crucial to the development of growth for the piglet. Before she is ready to give birth hours before the sow nest builds with straw, grass, and other materials in her environment. Nursing is frequent and is good for the growth of the piglets. The milk has an impact on nursing behavior individual patterns are repeated with sows.Feeding - You should feed them good clean food and feed them one time. Follow how much

Initially when seeing the fetal pigs, I was completely disgusted and figured I could not even look at them in the sink, let alone look at them when they are dissected. As my group pinned down the fetal pig and tied it’s limbs out of the way, I began to get more comfortable with the fact. As the dissection progressed, through observing the mouth and the thoracic cavity on the first day and the abdominal cavity on the second day, I became less grossed out. Observing the organs was interesting and I felt like it was a useful representation of what human organs are like, since it would not be ethical to use an actual human to dissect. I learned the difficulties that surgeons have to endure when performing a surgery. I can only imagine the high-pressure

Pigs are unable to move in their cages. The baby pig ears, tails are cut off and their teeth are chopped off to prevent them from harming other pigs. They are castrated without any pain killer. The baby pigs are given antibiotics to promote rapid growth. Their body grows, so fast, the legs become crippled. Many pigs are ill, but are kept alive to be shipped off to slaughter to get a profit. The pigs that did not make it to slaughter are shot with a gun to prevent them from eating the farmer’s feed. Pigs are abused by beating them with a gate rod to be moved from one place to another. Most pigs arrive at the slaughter lame or dead from the crowdedness during transporting. Pigs are electrically shocked to move on the killing floor of the slaughtering

A study done by French scientist Mathilde Tissier revealed certain eating habits in hamsters lead to them exhibiting extremely strange behavior. Tissier study began in the University of Strasbourg where her and her colleagues began to look into the effects of corn and wheat based diets in European hamsters. Not long after the female hamsters gave birth to their pups, they began behaving strangely, doing things like running around their cages directly after giving birth and picking up their pups and putting them in the piles of corn in their cages. But the most startling things the mother hamsters did, which makes this study that much more interesting, is the fact that they ate their babies alive. Only one of the hamsters didn’t eat her young

Mother pigs spend most of their miserable lives in tiny gestation and farrowing crates so small that they can’t even turn around and forced to get pregnant over and over again, until their bodies can’t handle it anymore.. Males are either killed immediately, or castrated at a young age then kept only for their meat. Piglets, in general, are torn away from their mothers after only a few weeks, tails are chopped off, and the ends of their teeth are snipped off, then the spend days to weeks to months in cramped, crowded pens on slabs of filthy concrete until it gets decided what will happen to them.
