Bovine somatotropin

without agriculture, we would be naked and hungry. However, many of these misconceptions are due to a lack of understanding about the farm to plate process within agriculture. Though, it is not always the people that are misled in their ways of thinking about the industry, many large corporations and organizations are often misguided in their thoughts and incorrect information is passed on to the public. Starting with press releases, to public relations from the companies themselves, and transitioning into things such as word of mouth by consumers. Take for instance the move by one of America’s largest ice cream brands, Breyers, who stated they were going to be using milk produced from cows who are not treated with the recombinant bovine somatotropin, or rBST hormone. This caused an uproar among many in the agricultural community, such as myself, who know that studies have found no difference between the fluid milk from rBST and non-rBST treated cows. In addition, we also know that this may not be the most sustainable method for milk production to produce a dairy product in such mass quantities. Both the USDA and the FDA have strict regulations in place to make sure that hormones like rBST are used in ways that do not harm, but benefit animals, along with keeping milk, meats, and byproducts safe for consumers to enjoy. Breyers’ packaging states that their products are hormone free to appeal to, often uneducated on dairy production, consumers. It does not stop with Breyers…

With both of these coming from unnatural backgrounds, there is no exact proof of it being safe. Along with no proof of it causing any harm. Growth hormones is a daily practice for farmers. The purpose of a growth hormone is to make the animals grow faster. “Either way, the backstory is the same: Agribusiness wants maximum return on investment in minimal time.” (p. 117) Baby calves are injected with hormones. Recombinant bovine growth hormone (rGBH) is given to dairy cattle to improve the amount…

Hunting is often portrayed purely as a form of sport or the quest for a big trophy. But what most people do not acknowledge is that it does much more for the human population in general. Hunting provides us with the resources that allow us to live comfortably. Not only does it do this, but it provides health to our environment as well as our economy. Hunting large game plays a vital role in the protection of our people, our resources, and the animals themselves. To begin, the killing of large…

Bovine brucellosis, which is caused by Brucella abortus, is a global zoonotic disease that primarily affects livestock (Rhyan, et al. 2013). The highly contagious bacterial disease can be found in both humans and animals. In humans, brucellosis can cause night sweats, recurrent fever, back and joint pain, arthritis, and other influenza like symptoms (Rhyan, et al. 2013). In livestock, it is known to cause abortions, arthritis, male reproductive tract lesions, retained placentas, and bursitis…

transform other cells (NINDS, 2003). About 85% of cases are sporadic, while 5-15% is familial (inherited). Each offspring has a 50% of inheriting the mutation on their PRNP gene (Gale, 2012). Living with a patient who has CJD does not increase your chances of receiving it than from the general population, but exposure to brain tissue and spinal cord fluid should be avoided (Gale, 2012). There is also Iatrogenic CJD which is when a person contracts the virus during a medical procedure. Some…

Additionally there have been strict restrictions placed on imported goods from other countries (especially Western Europe) known to have suffered from infections by prions. “To prevent BSE [bovine spongiform encephalopathy or Mad Cow Disease] from entering the United States, severe restrictions were placed on the importation of live ruminants, such as cattle, sheep, and goats, and certain ruminant products from countries where BSE was known to exist. These restrictions were later extended to…

Viviana Esteves Biology 1A Lab October 19, 2015 Mad Cow BSE Mad Cow disease is otherwise known as bovine spongiform encephalopathy (BSE). Bovine means that the disease affects mainly cows and cattle. Spongiform refers to the spongy look of an infected cows brain, prion causes holes and tissues to fold. Encephalopathy is any form of disease to the brain. BSE is found in more in younger cattle and cows. Other forms of BSE are found in humans, cats (feline spongiform encephalopathy), sheeps…

Creutzfeldt–Jacob Disease (CJD) is a rare degenerative disease of the brain. There are around 300 cases in the United States per year (NIH). CJD is also referred to as “mad cow” disease, this is because they carry the transmissible spongiform encephalopathy (TSE) (NIH). TSEs are caused by prions. In the brain, there are proteins called prions. Prions occur when a normal protein changes their shape which changes their function and are also capable of multiplying (NIH). There are two ways that…

Through the use of technology and science, scientists have discovered new diseases and how these diseases came about and how they are developing, such as the Prion Disease. After acknowledging the fact that our bodies have unique ways of morphing beneficiary aspects of our bodies into negative ones it was concluded that the affecting cause of the Prion Disease was not through a virus nor an infection, but thorough our very own protein found in the brain. Prion diseases have affected not only…

with a virus that had be inactivated with heat. The sample contained scrapie PrP, and the entire flock was infected with Scrapie (Vallabh S, 2013). Since the proteins form fibres, there are two places of conversion, meaning prion proteins are replicated rapidly; however, they have a long incubation period, so a prion disease can go years before any symptoms occur (CDC, 2015). Prion proteins are believed to originated from a messenger protein, a pathogen that lost its genetic material to the…
