The Biological Processes Of Dairy Cattle Essay

Animal cloning is getting popular by scientists day by day after the success of the sheep Dolly which was the first animal clone in the world. Dolly was created effectively by Roslin Instute scientist in Edinburgh (TechNyou) and she was euthanized when she was six year old due to a virus-induced lung tumour (Mott M., 2004). Even though the relevant scientists report that there is no evidence that cloning might be the cause of the disease of Dolly (Mott M., 2004), most of the scientists agree that cloning animals cannot be

Why did cattle ranching develop on the Great Plains? Cattle ranching developed on the Great Plains because vast fortunes were made. The cattle industry was based on some very important factors which were wild cattle, wild horses, and grass. These factors made cattle ranching very profitable, but however, for the cattle barons the bonanza didn’t last forever. In the North the market for beef was growing huge, and that meant ranching was a good way to live.

When eating anything, most people check the labels to see what the food all consists of. Just like when eating hamburger, some people may want to know if the hamburger came from grass-fed or grain-fed cattle. Depending on the person, they might prefer one over the other. Some people may think that one tastes better than the other or they may just think it is healthier. Not only might the meat coming from the cattle be affected, but also the milk coming from a cow. Either way, further explanations for grass-fed vs. grain-fed cattle will be discussed in this paper.

Animal cloning started without the world even knowing. First, an animal clone is “an exact physical copy of one ‘parent’” (Newman 12). “Animal cloning experiments began in the 1960’s. Frogs were the first subjects. By 1987 scientists had begun cloning cows and other mammals” (Newman 12). Dolly the sheep was the first big cloning success, credited to Ian Wilmut in 1996 (Praded 21). This sheep was a scientific breakthrough, but it also caused many people to question the intents of scientists. Many people wondered if scientists would clone humans next. The original intent of animal cloning was not for the food industry. The reason animal cloning started was to find a way to help cure currently untreatable diseases (“Why Do Scientists Clone?”). By cloning cells, scientists will be able to manipulate the cells to become something new.

The dairy cow has four main stages to its production cycle; these are early lactation, mid lactation, late lactation and the drying off period. The production cycle of the dairy cow is shown in diagram 1 below.

Before the food lab experiment where we tested milk, crackers, bananas, and egg whites for simple sugars, starch, and proteins I expected to learn about what foods contained any of the three possibilities, if not all of them. The lab provided my group and I information afterwards that can further my education into macromolecules and biology as a whole subject. My group and I predicted that milk will contain simple sugars, crackers will have simple sugars and starch, bananas will have proteins, and the egg whites will contain proteins. If milk does contain simple sugars, during this lab when my group and I test, then the milk should turn from a blue color to a green, yellow, orange, or red color when heated. Crackers should have the same outcome as milk if it does contain simple sugars, but if crackers also have starch the crackers should then turn into a blackish color. We predicted that bananas contain protein and if so, then the solution should turn from a light blue to either a dark blue or a purple. Finally, egg whites are what my group and I finally predicted to contain proteins. If our hypothesis is correct, the solution should do the same as it does for the bananas.

The reason I chose to use my show cattle as the main part of my video is because they are really important to me and have probably had biggest impact on my life as a whole. For the last 10 years I have been showing cattle and it has been a huge part of my life ever since. Showing cattle has taught me more about life and responsibility then anything else in my life ever has. Throughout the years of showing my cattle I have made many friends and been lots of places. The reason I chose the pictures that I did for my show cattle part of the video is because they show the way that I have grown and learned more over the last few years about showing cattle in specific. Having pictures of multiple years of calves that I have showed, explain how my showing abilities have improved since I started showing cattle. I mixed the different cattle that I have showed so that my video would show different perspectives of my show calves and the different breeds that I have showed. These pictures help me look back at the different shows I have been too with different calves helps me understand what I have improved on. Each calf that I have had, has been different in many ways, and each one has made me go out of my comfort zone in different ways and helped me learn new things such as, showing a different breed that I had no experience in, breaking calves to lead, new techniques for showing and prep, and figuring out new feed rations for my calves.

When most people think of cattle byproducts, they think of steak and leather, but are either forgetful or unaware of the other essential and inedible byproducts cattle provide society with. Many remain unaware that beef also contributes to vital goods and services. From airplane lubricants to piano keys produced from cattle bones, hormones and other products, arguably one of the most important cattle byproducts is medicine.

Saddle up everyone. It looks like there’s a Longhorn coming down the road. Based on its speed, this steer’s power must be enough to send even the toughest cowboys into the dirt on which they stand. A cloud of dust rises in the distance as the beast approaches, but is it animal or is it mechanical? Its massive countenance resembles that of a bovine animal with its beady, flashing eyes and its flaring nostrils atop a toothless grin. Its colossal horns stretch across the forehead creating a menacing glare. As the distance closes, I blink again and realize that it is not a steer at all. It’s merely a convertible decked out as the perfect ride for any cowboy. The eyes were the headlights, the nostrils were grill ornaments,

When we look at the sky, what do we see? Stars. What would it look like if there was an entire galaxy in view? That is exactly what will happen within four billion years. Our galaxy, the Milky Way Galaxy, is fated to collide with the Andromeda Galaxy, or M31. Scientists have been asking this question for decades, about how likely it is, or if it will even happen at all! But some newer evidence to this dilemma has revealed itself. Now that it is widely accepted as an inevitable fact, many questions are being asked, such as, “How probable is it?” and one of the most asked questions of them all, “Will we (humans in general) be around to see it?”. The answer is probably not, and here is why.

Canadienne Cattle are dairy cattle that originated in Canada and is starting to become more popular in the United States. Canadienne cattle were the main cattle breed up until 1850. The breed developed it’s own official herd book in 1886 when they were almost extinct. The population of the Canadienne was nearly 300,000 head before the book was developed. Today, the breed is not as common, but it still thrives (The Canadienne Cow, 2009).

Have you ever had a burger from a restaurant and each burger you eat has the same beef taste if you’ve noticed from the label the burger is labeled beef, but what kind of beef? Let’s say you have a burger with Angus beef and a burger with regular beef you can tell the difference, the Angus beef taste much better than the regular beef. The Black Angus Cow is a main keystone for the meat industry in America and this breed of cow has changed how we eat and produce meat. Due to the uniqueness of this breed it is important to understand about what the Black Angus Cow is, how it got to America, where it came from, who brought it over, why it is so important, how to take care of it, and why it's so special.

Two years ago, I started doing 4-H. I did not want to do it, but because of my little brother and all of his little reasons why he wanted to do it, I had to. We decided to do dairy heifers. When I first got mine, I hated it. It was ugly, mean, dumb, and smelly. The only time I have been around farm animals is when I am with my cousin. When I first started out with 4-H, I knew nothing about my animal. We keep our dairy heifers about five miles away from our house. Every morning and night we have to go feed and walk our heifers. It is harder than you think to walk a heifer. First you have to halter it, and it is not easy. Some days it would take us an hour just to try and halter it. Then you have to walk slowly with it to get it to calm down. It is also sometimes confusing to fed them. We have to measure our food when we feed them. We at least have to feed them 25 to 50

Cows produce a protein in their milk called BLG and many infants are allergic to this protein. Two to three hundred infants are allergic to cow’s milk, and BLG allergies are seemingly a large part of this. Various organizations are trying to investigate ways to manipulate the genetic material in the modified dairy cattle with the main goal of producing milk that doesn’t contain the lethal BLG protein. Daisy is a genetically modified cloned cow and whom does not produce milk containing the BLG protein but does however have the gene for it. But the mRNA for the BLG protein has become nonfunctional. Once the protein has been manipulated the cow containing the modified gene is cloned to produce a calf with the same genetic material. This cloned cow will then not produce the protein. This technique is very useful to produce a herd without the protein to gather more milk. Because of this protein produced (BLG) this causes a lot of people and infants to become very sick and ill. Therefore by creating a herd of cows using the processes of Gene Knockdown and Cloning this would not only cut out the lethal protein of BLG, but this will also create cows that don’t possess the BLG protein and therefore creating healthy milk for all to drink.

Mastitis is a condition affecting dairy cows that has significant impacts on producers, processors and consumers. The disease causes a reduction in milk yield and quality, as well as contributing to antibiotic use and the development of resistant bacterial strains. Mastitis can also increase the susceptibility of an affected cow to secondary health issues due to immune suppression caused by the infection. Physiological, environmental and management factors can all increase the risk of a cow developing mastitis, and farmers invest significant time and money into controlling these factors.
