Over the years, farmers have preferred using selective breeding than traditional breeding as selective breeding produces animals with desired traits while traditional breeding is time-consuming. With the advance of biotechnology, various molecular techniques have enabled animals with desirable traits to be produced in a shorter time with more precision. The first transgenic farm animals was reported in the mid-1980s, where microinjection of DNA was used to transfer the gene into the target (Margawati, 2003; Muller & Brem, 2001). Initially, growth performance is the main focus of transgenic approach towards the farm animals. However, growth is a very complex process which is affected by various factors such as the interaction of hormones, nutritional conditions and environmental factors. According to Muller and Brem (2001), gene constructs which contain the genes of the growth hormone (GH) cascade was used to generate transgenic pigs. As a res...

- Transgenic Animals A transgenic animal is an animal that has a gene from another species and that gene is expressed in the foreign organism. A transgenic trait can be used to benefit humans and animals. It can also increase the efficiency of the animal. As the more common transgenic animals become, the more controversy is tagged along with the debate. Some of the questions that have been raised: Are they safe. How will this affect the animal in the long run. Is this research ethically just. What does the Bible say about manipulating the genomes of various species....

- If people were to become antibiotic-resistant, how would we cure the diseases that are incurable without antibiotics. When at the doctors receiving medicine, most people don't realize they are receiving a form of antibiotics. If us humans became resistant to this drug then Scarlet fever, the flu, and even a common cold would become severe problems because many americans have never fought away these illnesses without the help of antibiotics. Growth hormones (GH) are also commonly used today in CAFOs.... [tags: food, nutrition value, transgenic hormones]

- Genetically modified animals are an important category of the genetically modified organisms (EFSA, 2012). From EFSA and Paul Arnold (2013), genetic engineering of an animal involves manipulating or modifying the genetic code of the targeted animal to alter their original characteristics and introduce certain desired traits to the animal by adding to, substituting with or removing from genes of interest in a way that does not occur naturally (EFSA, 2012; Arnold, 2013). The genes of interest can be derived from another animal of the same species, an animal of another species, or even an organism of another kingdom (Arnold, 2013).... [tags: dna, organisms, genes]

- Luscious red-ripe tomatoes, picture perfect ears of corn, spotless potatoes, high-yielding soy, acres and acres of wheat, fluffy-white cotton laden trees; all disease and pest resistant, drought-tolerant and inexpensive. What a grand vision of flawless and abundant crops. It’s not a vision, it is reality- with a little help from GMO’s. But is it really so. This wonderful actuality is in fact an illusory fallacy. Genetically modified food production is based on practices that are not natural and to an extent unethical.... [tags: Genetically modified food]

- Introduction The debate over whether to keep the production genetically modified organisms, or to cease it all together. They help many countries around the world with low food sources, due to climate and other hindrances. With GMO’s aiding countries in need, it will have a helping hand for the availability of more food. These crops and livestock promote ideal solutions to nutrition, world hunger and the environment. With all that being said, GMO foods are one of the most frowned upon food sources in the world.... [tags: Genetically modified organism]

- Since the mid 1990’s Americans have been enjoying larger, better tasting, and more nourishing produce. Farmers and ranchers have been able to produce higher yields of crop in less amount of time. Produce is also more resistant to disease and can grow in a large range of climates with different soils while requiring less water. So what has caused all of these great “food miracles” over the last 20 years. Did Mother Nature decide to give us a break. No, not quite. As a matter of fact, these foods aren’t natural at all....

- For the entire length of human existence, people have sought to better technology in order to advance society. In agriculture, the newest technology to improve crops is modifying genes directly through biotechnology. Genetically modified (GM) foods have foreign genes implemented into their genetic code in order to achieve a desired trait. (Phillips, 2008) These crops can have the potential to reduce pesticide use, increase nutrients, resist pests and damaging herbicides, increase yield, and provide medical benefits....

AIDS mouse, alzheimer's mice, oncomouse and transpharmers animal are some transgenic animals that are used as disease models (Martin & Caldwell 2011). According to Susan Wilson, associate director of Sanders University Animal Care, animals are modified by inserting human disease gene into an animal for the animal to be studied as disease models (Armao M 2013)....

Another 3,400 are murdered by unknown pathogens such as bacteria, toxins, viruses, and prions transmitted through GM food (Frenzen). Prions are infectious protein particles, unlike a virus, contains no nucleic acid, does not trigger an immune response, and is not destroyed by extreme heat or cold(). Prions that enter the human body can alter the immune system killing thousands of cells triggering disease in the tissues.... [tags: food, crops, animals, nurtition, inject]
