Animal Castration Research Paper

Animal testing has become a wide contribution in medical field in order to find new treatment, developing new medicines and improving the existing ones as well as testing the safety and effectiveness of new medicines. Some medicines development is depending on animal research, for instances, vaccines and insulin for diabetes and kidney transplants. However, there are many diseases that their cures are still undiscovered yet and one of them is AIDS (Tanir, 2012). Frankie L. Trull once said in his article of Animal Test Research Has Saved Many Human Lives, “[…] fight against cancer has seen 24 significant biomedical advances in the past 30 years. None of them could have occurred without animal research.” Therefore, this

A CIDR is a T-shaped device with flexible wings that move to form a rod to insert into the vagina, and a tail is attached to make removal as easy as possible. The CIDR 's nylon spine is covered with a progesterone embedded silicone skin. The CIDR is inserted for seven days, which causes the female’s blood progesterone levels to rise rapidly, with maximum concentrations reached within an hour of insertion. Progesterone levels are maintained at a constant level during the following week. When the CIDR is removed, progesterone concentrations rapidly decrease. Caution should be taken when handling CIDRs; always wear gloves to prevent exposure to progesterone and the introduction of contaminants into the vaginas of other cows. The CIDR 's greatest advantage is to facilitate fixed-time artificial insemination, where no estrus detection is necessary. The protocol is simple, but there are some differences in timing for mature cows and young heifers. For all females, the CIDR is inserted and a GnRH vaccine, such as Cystorelin or Factrel, is injected at the same time. Seven days later, the CIDR is removed and the cow receives a prostaglandin F2 injection, such as Lutalyse. In mature cows, artificial insemination should occur sixty to sixty six hours after CIDR removal, and a second GnRH injection should be

Porcine Zona Pellucida, or PZP is a vaccine hand injected into mares to prevent pregnancy. The National Academy of Sciences states “The Porcine Zona Pellucida (PZP) vaccine, an immunocontraceptive, is the most extensively tested method in free-ranging horses and ma be the most promising option at present” (Using Science to Improve the BLM Wild Horse and Burro Program a way forward 113). The vaccine is temporary but effective for up to twenty-two months. The effects of PZP wears off and normal reproduction can resume four years after the injection. This is a treatment and release program that is not harmful. They use helicopter roundups to gather the horses and separate out the mares in order to vaccinate them. Modified rifles with loaded darts of PZP can also be used to vaccinate the mares. It is not harmful to the animals and the lifespan increases and health improves with the vaccinated mares. Mares that are vaccinated live 5-10 years longer than untreated mares. (“Fertility Control” 1). The goal of this method is to reduce the population to match the carrying capacity of the land. Rashmi Shivni agrees when he writes “The Ultimate goal is to lower the population to match the carrying capacity of the land, and Dr. Mcdonnell said the best way to do this is to control fertility” (Shivni 2). Porcine Zona Pellucida vaccine controls the

In One Flew Over the Cuckoo’s Nest, Kesey uses the motif of castration to show that women have the power to emasculate even the most masculine of men, displaying the issues with extreme sexism.

Castration, also known as emasculation, is the deprivation of a man’s masculinity, individuality, and the demotion of male dominance. In the novel One Flew Over the Cuckoo’s Nest by Ken Kesey, Nurse Ratched, the head nurse of a mental institution,castrates the male patients using her mechanical surveillance and manipulation,ensuring their perpetual submission to her control. She is portrayed to be an inhumane character who callously oppresses the male patients and enforces her power to emasculate them. As a matriarch, Nurse Ratched enforced her power and emasculated the men to maintain her strict control over them, stripping their independence, through the suppression of their sexuality, employing physical force, intimidation, and manipulation.

To continue, I then began to examine the endocrine system of the fetal pig. I began this dissection by finding the endocrine organs that are located in the area of throat. These organs were the thyroid and thymus. The thyroid’s responsibility is to produce amino acids that will help to regulate metabolism. The shape of the thyroid is oval like, and has a dark brown tint. The second endocrine organ found in the throat is the thymus. The thymus functions to provide immunity against diseases. It has a pink appearance, and is long in length. I was successful in finding three endocrine organs in the abdominal cavity. The first organ found was the adrenal gland. The function of this gland is to produce various hormones. This gland is identifiable

If you’re considering the adoption of a fuzzy friend or have recently done so, know that spaying or neutering is essential. Spaying and neutering services are readily available through Fairport Animal Hospital, the pet clinic that proudly serves the four-legged residents of Fairport, NY and the surrounding area. Review why veterinarians at the premier animal hospital continually emphasize the importance of spaying and neutering before booking an appointment:

The issue of whether sex offenders should be chemically or physically castrated has been one that has sparked much debate over the years. There are many people who believe, apart from murder or treason, that sexual abuse is one of the worst crimes that a person can commit against another. In these circumstances, many have voiced the proposition that such an offender, especially when they are repeat offenders, be punished in the harshest way allowed. Apart from the obvious jail term, the extra punishment would be either surgical or chemical castration (Beech & Grubin, 2010). Castration has two ways that it can be done: surgical and chemical. Surgical castration involves the removal of the testes and chemical castration uses hormones to drastically reduce the testosterone levels in

Susie Cue started off with one cat, Snowball. She loved that cat, one day she ran away and disappeared for multiple days. Susie was overwhelmed with sadness, until Snowball reappeared. Susie decided to take Snowball on a trip to the vet to make sure she did not have any diseases or problems. There weren’t any problems, but her cat ended up being pregnant. Since spaying and neutering was not a thing, she could not avoid the inevitable. The cat ended up giving birth to six kittens. Susie kept all of them and the same thing continued to occur, the cats ran away and became pregnant. At the end of the year, Susie had over fifty cats. The world without spaying and neutering leads to an enormous amount of animals that are beyond limits of controlling. These animals get abandoned, people are unable to take care of them,

Is it fair to do experiments on a helpless animal for the benefits of human beings? No,it is not fair to do experiments on helpless animals. Animal testing is when cruel and harmful experiments are done on innocent animals for specific reasons such as saving human lives. In animal testing, they take these innocent little animals and run horrible,cruel, and graphic test on them. "An estimated 26 million animals are used every year in the United States for scientific and commercial testing." (Humane Society International n.p.). So many different kinds of animals are taken captive to be tested on these gruesome experiments. There are many experiments

Animal science is a very broad topic. Form General Animal Science class I have learned that animal science is concerned with the science and also with the business to produce livestock such as cattle, horses, sheep, swine and poultry. In this course I have also learned that the scientists apply various genetic modifications on animal to increase production and management of livestock. To supply for the demand of animal in worldwide the industries of livestock are responsible for maintaining the well-being of the animals. The three concepts that I learned after taking this class are choosing the right breed of animal is necessary for mass production, genetic selection, and food safety.

Imagine you! as a cow on a conveyor belt ready to be slaughtered and suddenly, before you know it MOO! you! just got slaughtered into all these different meat parts just so you can be sold and then eaten by humans.

Should people hurt animals? Should people kill animals for human drugs? These are questions citizens need to ask themselves everyday. Many animals are being hurt or killed every year because scientists are testing on them. Animals do not deserve this abuse just for human gain. Animal testing is wrong and should be stopped, because animals are being hurt and mistreated and the scientists are not using new methods, and developing bad drugs. Approximately 23 million animals are being tested each year, according to the Office of Technology Assessment. This is not ok, the madness needs to stop.

It is common for the semen of 2-3 bulls to be used to ensure at least one quality sample to produce a pregnancy. In the instance that multiple donors are used, parentage is confirmed via DNA analysis. Most frequently, nonsurgical insemination is performed. This method calls for a trained and accommodating elephant as a large bore cannula is inserted into the lower urogenital tract. A 3m endoscope is inserted through the cannula and conducted to the hymen in first time mothers and the cervix or uterine horn of a cow that has calved. A small insemination cannula is used to deposit semen into the vagina, threaded through the hymen in nulliparous cows. In parous cows the semen may be deposited further into the uterus.14 Surgical insemination
