Genetic Engineering For Farm Animal example essay topic

Genetic engineering is a new development in 20 century's technology and it became very animation until now. One of the most comments used is transferring the gene proteins from one thing to anther, which can improve the food quality. We called these food transgenic products. However there still have many considerations. There is a growth hormone in the cows called the bovine somatotrophin (BST), which stimulate them to produce more milk. In 1980 the scientists of America used genetic engineering to extract the DNA, which controlled the hormone BST from the cows cells.

Then the scientists transferred this DNA into bacteria's and found that BST can produce fast in the bacteria. Then the scientists took those BST from the bacteria injected into the cows. The cows developed better appetites after regular injections of the extra hormone BST and secreted large amount of milk. The Bureau of Foods & Drugs of America approved that the milk was safe for consumption. But the immune- system was affected and did not work properly after overdose of BST in the cows. The biggest side effect was the increase of infection of the cow breast, so antibiotics were injected into them to treat their infected breasts also helps strengthen their low immune- system.

However a hazard was created as the residual antibiotic deposited in the milk, ice cream (etc. dairy products). Therefore the environment was contaminated. There are many advantages of the genetic engineering in animal husbandry. Not only increase the amount of product but also detect of many diseases earlier. One of the main purposes that we used genetic engineering for farm animal is to increase in the amount of the milk produced per cow. Milk is the major food for our breakfast, so it requires a lot of yield.

Also the prices become cheaper because of more yield. And the poor can hold to buy more. Other advantage is by using genetic engineering to prolong shelf life of meat. For instance, the scientists used fish gene transfer into tomatoes and these tomatoes can put on the shelf for longer time. The last but not the least.

Now the technology of genetic engineering can detect and treat the diseases such as congenital inheritance or cancer, etc. To change on the new DNA, take off the congenital part. Some incurable disease also can be healed. In the other hand, any good thing will have its negative part behind. For the genetic engineering, there still have some unknown harms, ethical and biological concerns. Green party also does not want genetic engineering food.

One of the disadvantage is the genetic engineering lead to the eugenics, the weak specimen is loosing in the future. But who will know that those weak parts may become important and be developed in the future. As with any new technology, the set of risks associated with genetic engineering have almost certainly not been identified. The ability to imagine what might go wrong with a technology is limited by the currently incomplete understand of physiology, genetics, and nutrition. One of the most ethical concerns is the genetic engineering food may against religion. Transferring animal genes into plants raises important ethical issues for vegetarians and religious group.

It may also involve animal experiments, which are unacceptable to many people. At the last, the environment is contaminated. Because of transferring the gene from one to another, plants contain animal's genes; animals contain human's genes. It is unpredictable what may happen to the next generation. In the conclusion, nothing can be perfect in this world. Learning how to use genetic engineering at the right way is very important.

By testing thousand times and then give the safest food for people to enjoy.
