Introduction: This unit, about Enzymes and Biotechnology, contains information on how enzymes work in chemical reaction. For every enzyme there is a substrate made of reactant molecules that is worked upon. During a chemical reaction, the enzyme lactase breaks lactose molecules into their monomers, glucose and galactose. This lab is observing enzyme specificity as demonstrated by how lactase affects the presence of glucose in soy, cow, and rice milk.
Data:

Conclusion:
1. Cow milk contains lactose, the substrate for lactase. When an enzyme-substrate complex is formed between the lactose and lactase, the enzyme breaks the lactose down into its monomers, glucose and galactose. The results for the glucose test strip were negative before the

Odhi Case

...Executive Summary The Ontario Dairy Herd Improvement Corporation is a non- profit organization, which provides milk-testing services for Ontario dairy producers. Physical facilities include a head office and computer system located in Guelph, as well as milk testing labs in Kemptville and Woodstock. Ontario DHI’s mission is to maintain an organization that will deliver an accurate, timely and cost-effective milk testing service and promote improvements in the efficiency and profitability of dairy production in the province of Ontario. ODHI has been facing several problems. Although ODHI has a moderate financial surplus, the number of members subscribing to the services has been declining at about three percent per year for the past five years. Moreover, government funding did not keep up with inflation. This led to the increase in fee paid by the members. As a result of higher prices, members were discontinuing the services offered by Ontario Dairy Herd Improvement Corporation. John Meek, newly appointed general manager conducted a market research through in depth interviews and mail surveys. Based on the results, ODHI has to decide on pricing the service for different customer segments in the market. In response to these problems, ODHI should choose alternative 1, which inclined on cutting cost in 3 different ways, for customers who are significantly price-sensitive and are looking for substitutes. Ontario DHI also has a second option that imposes a use of advertisements...

Animal Suffering

...When you go out to eat and look at your thick and juicy T-bone steak what do you think about? When you look at that gorgeous mink coat in the department store what is going through your mind? When you here that cigarette smoke causes cancer in lab animals what is the first thing that comes to mind? Chances are that in each of these cases you were not thinking about how the cow suffered while it was being fattened up, ho painful the trap was that caught those mink, or the conditions those lab animals hat to endure to develop that cancer. Most people do not think about these things. However, in this paper, you will be enlightened on the pain and suffering of animals in three different industries and you will also hear from the other side of this issue. First, one of the biggest culprits of animal suffering is the animal food industry. This is an industry in which people have a tendency to block out or ignore the animal mistreatment; this is done by disassociating oneself with the direct harm and ignoring the indirect harm (Harnack 133). A good start under this example in the case of pigs. Normally, pigs are intelligent animals capable of showing affection. They have very good senses of smell, which is why pigs have been used as hunting animals (Coats 31). This normal behavior is disrupted however in the food industry. Pigs are taken to slaughter at about twenty-four weeks of age when they are approximately 220 pounds (Coats 32). Pigs are usually mass-caged into...

The region is swampy, fertile for growing rice; some oil fields are located near the town in the seasonally inundated [Insert the details of Badin from Internet Badin website] LIVESTOCK MANAGEMENT AND SOCIO-ECONOMIC ASPECTS It is not easy to introduce technological innovations in livestock production at the level of the smallholder. Without adequate knowledge of taboos, customs and the sociology of village communities, the researcher has little hope of establishing methods to improve traditional systems. Subsistence farmers must first ensure their families' food supply. Only then can they think of improving the condition of their livestock. Thus, if technical innovations are to be successful, they must be introduced taking into account the following requirements: • There must be an immediate financial return from the application of the innovation • The innovation must be relatively simple and should not interfere with normal farm activities, such as planting or harvesting • The livestock venture must entail minimal risk • The innovation should not be hazardous or arduous, unless returns are exceptionally high • It should not cut across religious or other cultural activities. The introduction of technologies is discussed in detail by Dolberg (1982, 1983) on the basis of experiences with the development of new livestock technologies in India and Bangladesh. His analytical framework...

The slaughterhouse is enormous, ten football pitches long with 11km of conveyor belts. Its managers attend to the tiniest detail. The fly­swatting workers wear green rather than white because this puts the pigs in a better mood. The cutting machine photographs a carcass before adjusting its blades to its exact contours. The company calibrates not only how to carve the flesh, but also where the various parts will fetch the highest prices: the bacon goes to Britain and the trotters to China. Denmark is a tiny country, with 5.6m people and wallet­draining labour costs. But it is an agricultural giant, home to 30m pigs and a quiverful of global brands. In 2011 farm products made up 20% of its goods exports. The value of food exports grew from €4 billion ($5.5 billion) in 2001 to €16.1 billion in 2011. The government expects it to rise by a further €6.7 billion by 2020.

I M A Grass Farmer

...1. When Salatin states, “I’m a grass farmer?” he means that grass is his main material from which the rest of the animals on his farm benefit from. The hay the livestock eat have been grazed twice by beef cattle and then afterwards Salatin brings his chickens peck out bugs and larvae out of the cow manure. Their presence spreads their manure like fertilizer for the grass. The chickens then release nitrogen and lays some eggs. The grass then rests for some time and the cycle happens again. The chicken’s contribution to this part of cycle removes the need for chemical parasiticides. So basically, grass is Salatin’s prized ‘crop’. 2. When Pollan discusses the “invention of agriculture,” he is referring to the marriage of grasses and humans. The...

...Palmer and microbiologist Tyler Thacker are collaborating with international groups, other U.S. government agencies, the cattle industry and private companies to combat TB. They are developing better tests to help producers identify and remove TB-infected cattle from herds and keep healthy animals. Widespread pasteurization of milk, development of a diagnostic tuberculin skin test for cattle and establishment of a USDA eradication program have significantly helped decrease the incidence of bovine TB in humans in the U.S. While the tuberculin skin test for cattle has helped eradication efforts, it does have drawbacks. "The test is not sensitive enough and requires a 72-hour waiting period for results," Palmer said. "It's very difficult to test a herd of 100 cows and say that this one has TB and this one doesn't because the test may not detect one or two animals that actually have TB." Interferon-gamma-release assays, another method used to detect TB, are whole-blood tests that require live white blood cells to work. Fresh blood samples must not get too hot and must be processed within 8-30 hours, which requires getting samples to a lab in good condition within a...

Cloning: Right or Wrong?

...Running Head: CLONING RIGHT OR WRONG? Cloning Right or Wrong? Should the cloning of humans be legalized? Diane Lentz English 215 Strayer University Online Cloning Right or Wrong? Should the Cloning of Humans be Legalized? Scientists have been cloning animals from embryonic cells for decades (Cowen, 2001). With the introduction of Dolly, the first animal cloned from mature tissue, the issue of cloning has reached a fevered pitch. Individuals for cloning and those against are taking their battle to new arenas, such as congress. The battle will continue as research progresses. The process of cloning and the information compiled from cloned animal experiments are as important as the benefits and complications as well as the ethical and legal ramifications of it, which are at the core of the modern day debate. In 1997, a sheep named Dolly gained national recognition. Dr. Ian Wilmut, a Scottish scientist from the Roslin Institute, introduced her to the world as a genetic copy of her mother. Animals, as humans, receive half of their DNA from their mother and half from their father. This creates a unique individual. It took scientists 277 tries to succeed in creating Dolly. While Dolly has the same DNA as her mother, they are different in many ways. Human twins share the same DNA but have different personalities due to life experiences. The process Dr. Wilmut used to create Dolly is called “nuclear transfer...

The framework allows for an understanding of the cross-sector economic influence of zoonoses using improved risk analysis and listing a range of analytical tools. The goal of the framework is to link the check outputs of animal and human disease transmission models, economic influence models and assessment of risk management options to gain improved understanding of factors affecting the acceptance of risk management plans so that investment planning includes the most promising interventions (or sets of interventions in an integrated fashion). A more complete understanding of the costs of the disease and the costs and benefits of control measures would promote broader application of the most efficient and effective control...
