How Does Genetically Modified Animals Help Farmers
Genetically modified animals refer to animals whose genetic material has been altered by utilise of a genetic engineering or recombinant DNA technology. Genetic modification technology is used for a number of reasons. For instance, in the field of agriculture, most agro-businesses have invested heavily in GMO technology to produce high quality species inside a short fourth dimension. In add-on, GMO has given a ascent to genetically modified animal products. These include fish, chicken and pigs amidst other animals.
Farm Animals
The concept of genetic technology has gained widespread popularity amongst poultry and pig farmers. In adult countries, such as, the U.s.a. and Great britain, chicken farming has been genetically modified to ensure that enough chickens are produced within a short time, to meet the ever-increasing consumer demand. Product of chicken through caged environments ensures that chicks mature speedily than in ordinary environs. Engdahl explains, "in the 1940s, broilers required at least 12 weeks to larn market weight (4.4 pounds) whereas, due to unnatural elements of industrialized product methods, they attain that weight and are killed at simply 6 weeks" (287).
Similarly, in pig farming, the use of GMO is as enhanced. Whereas a natural brought upwards pig takes months to mature and attain marketplace size, a pig raised under controlled environments through GMO takes a paltry 3 months to attain a slaughtering age. In the Usa, for instance, merely iv farmers are enough to produce pigs required to feed the population of an entire state. Piglets are fed with growth hormones and nutrients that promote fast growth (Engdahl 292).
The main company that was pushed for the utilise of genetically modified foods in the United States was Monsanto (Engdahl iv). This company, though aware of the wellness problems associated with these foods, had successfully won the support of the government and was able to push for the commercial and large-scale use of their products. Genetic engineering mainly involves the alteration of the genes of a institute or an animal. The genes inserted for the purpose of altering the genetic configuration of a institute or creature come up from a different species. This in nature occurs when exogenous Deoxyribonucleic acid gets into the cell membrane of another constitute or animal. This ends up altering the genetic configuration of the original cell. This can be achieved artificially by attaching the genes to a virus. This virus so penetrates the prison cell membrane and hooks the attached Deoxyribonucleic acid to the prison cell nucleus. This transfer can be achieved through other methods such every bit inserting the extra gene to the nucleus through the employ of a small syringe or using a gene gun plus other methods
The effects of genetically modified nutrient substances came to the public domain after the inquiry conducted by Dr. Pusztai. The research unearthed many furnishings of the genetically modified foods that had not been revealed to the public before. He realized that the " rats that were eating the genetically were significantly smaller in size and torso weight than ordinary white potato-fed command rats in the same experiment" he also discovered "… the fact that the GMO rats showed markedly smaller liver and eye sizes and demonstrated weaker allowed systems. Smaller brain sizes of GMO-fed rats compared with the normal potato fed rats" (Engdahl 23). These were revelations that inverse the perception of the whole thought of human beings consuming genetically modified foods. Before it had been reported that cows that were treated with Rbgh on the promise that they would mark an increase on milk production showed problems such as mastitis, an inflammation of the udder, and deformed births.
Live Conversation
The effects of genetically modified animals and plants were initially unknown due to the way the American food and drugs bureau was handling this issue. The government had made sure that the created policies were meant to view genetically modified foods in the aforementioned way as normal crops. Monsanto had made sure that the government was in its expert books and at 1 point the food and drugs agency created a position of deputy commissioner for policy to oversee agency policy that was filled by a Monsanto friendly lawyer (Engdahl 10). The government failed to enforce and make policies that would check the effects of genetically modified foods. The effects of genetically modified substances can in no mode exist expected to be like to those of normal foods. Altering the genetic composition of whatever substance is likely to have both positive and negative consequences both to the consumer and the plant or animal. The effects may non exist short term only may be realized with time as the effects of the compounds in the food substance are absorbed into the body of the plant or animate being. Like in the example of the cows treated to produce more milk, the result was realized after virtually two years when then udder and calves showed signs of abnormalities and sick health (Engdahl x). The discoveries of Dr. Pusztai were shocking, but they revealed exactly what human beings were being subjected to. The effects were felt badly past the animals that had been modified. It as well showed that if human beings were to consume the plants that had been modified for quite some time, they were likely to develop like defects as the one experienced by the rats. If man beings were to accept smaller brains and weak immune systems that would have devastating furnishings on human life, the animals modified were likewise suffering because they were easily prone to infections, dissimilar the normal animals. The furnishings of this tin longer be hidden, and this calls for strict measures to protect both human life and the animals.

Researchers have delved into cloning and genetic technology of almost all animals and plants they tin access. There are different categories of animals that have been genetically modified.
Companion Animals
These are mutual types of fish that have been genetically engineered for utilize every bit pets though at that place accept been campaigns for their consumption as food. An example is the genetic modification of zebra fish was attained by inserting genes of sea anemone and jelly fish. The result is known as "GloFish" which expresses proteins. They have been marketed in the U.s. since 2003 every bit ornamental pet fish (Ormandy, Dale, and Griffin 545). This, however, has sparked ethical controversies with sections of the media and ethical organizations calling for their bans. Gene knock-out technique is another popular method that scientists are employing to produce the then called "designer" companion animals. Hypoallergenic true cat is produced by some companies by removing the gene that codes for the cat allergies Fel d1. Cloning is another method used to create companion animals. Cats and dogs have been successfully cloned since 2002. Ethical problems have stalled the growth of this field of companion animals (Ormandy, Dale, and Griffin 545). There is hope that people in the future are going to adopt genetically modified pets for their day to day activities and that cloning will too gain popularity, equally clients clone their dead pets.

In decision, genetic applied science has numerous benefits to both human beings and the animals, but sure ethical issues are ordinarily raised. These issues are from those who are concerned with upstanding values regarding procedures and the consequences on the parties involved. Animals are used during research and the modification process. This process involves surgical procedures that include vasectomy, surgical embryo transfers etcetera. These procedures affect animals that are undergoing the process and they are unethical (Ormandy, Dale, and Griffin 545). These animals are subjected to processes that forever change their lives.
Most of the embryos that undergo genetic modification do not survive which practically means a large number of animals are needed. Advances in technology are underway to ensure that a large number of embryos survive during implantation. The currently available technologies are highly ineffective which leaves only a small percentage of embryos to survive. There are many bug associated with genetic modifications, and the long term benefit of these methods is under scrutiny (Ormandy, Dale, and Griffin 545). The overall benefits of genetic modification are felt in the brusque term, but as research has suggested long term effects might exist negative with some having permanent damage on consumers and the genetically modified animals. Circumspection needs to exist taken before big scale cloning and genetic modification of animals tin be done to avoid putting human being and brute races at a threat (Sjöberg 164).
