Biotech...livestock pwpt....

  1. 1. Abdul - Alim Muhammad Shanice Turner Kiersten Porter How Biotechnology has impacted the livestock industry. Biotechnology Ms. Spee 8th period June 8, 2010
  2. 2. <ul><li>What is animal breeding? </li></ul><ul><li>Animal Breeding is the use of genetics and biometry to improve the efficiency of production in farm animals. </li></ul><ul><li>Biometrics is the technology that measures and analyzes body characteristics (fingerprints, eye retinas, voice patterns, facial patterns, etc.) </li></ul><ul><li>Animal breeding helps the livestock industry in many ways, including help make the animals more immune to diseases; and produce faster so that they could be sold faster (more money) </li></ul>Animal Breeding
  3. 3. <ul><li>There have been reports – in the past – of abuse going on at breeding facilities. </li></ul><ul><li>The abuse would be hitting and jabbing animals - pigs in this case – with metal rods and other instruments. </li></ul><ul><li>Also, the pigs’ eyes were being gouged and they were poked and slapped by the facilities workers. </li></ul><ul><li>Some pigs suffered from softball-size cysts, oozing sores, and other painful injuries, but they did not receive any veterinary care. </li></ul><ul><li>Not a very efficient way to breed animals, no? </li></ul>Animal Breeding – Abuse
  4. 4. <ul><li>Animal Cloning is when an entire organism is reproduced from a single cell from the parent organism; The organism will later become a clone, which is an exact duplicate its parent – it has the same exact DNA. </li></ul>Cloning Animals
  5. 5. <ul><li>Birth defects, physiological impairments, illness, and premature death continue to be the norm, not the exception, with cloning. </li></ul>Animal Cloning - Issues
  6. 6. <ul><li>Genetic Engineering has been done for centuries – in animals and plants by selective breeding. </li></ul><ul><li>Selective Breeding is when someone breeds certain plants and animals to get the desired characteristics that will be passed on to the next generation (the child). </li></ul><ul><li>Can sometimes occur with mating – selective mating, or in the lab. Altering the genes of a particular animal or plant can affect its appearance, and – for an animal, its meat. </li></ul><ul><li>Even though it may seem easier and faster to use this method of genetic engineering for animals – it can not really speed up production of the animal. </li></ul>Genetic Engineering of Animals
  7. 7. <ul><li>There have be issues with genetic engineering, however, for example – mice which had been genetically modified with a human gene to shut down a gene that made the mouse immune to other genes – the mouse had developed a few symptoms of a human disease – one being a form(s) of cancer. </li></ul><ul><li>If this happens with another animals, like a pig, then the meat would be affected and if it is feed to humans ‘accidentally’, it could be health issues. </li></ul>Genetic Engineering - Issues
  8. 8. Use of recombinant and nonrecombinant hormones. <ul><li>Hormones are used in animals to enhance their growth. </li></ul><ul><li>A common hormone is bovine somatotropin. This hormone is mostly used in cattle to increase milk production. </li></ul><ul><li>In 1994, the hormone could be synthesized using recombinant DNA technology to create recombinant bovine somatotropin. </li></ul><ul><li>The use of this hormone has become controversial after it produced defects in the cattle. </li></ul>
  9. 9. Use of recombinant and non recombinant antibiotics. <ul><li>Antibiotics are used in livestock biotechnology to reduce the amount of diseases among the animals. </li></ul><ul><li>If one animal out of the herd gets sick, the whole herd is treated with antibiotics. This has caused controversy because healthy animals are being fed antibiotics which will eventually damage their health. </li></ul>
