Elephant Reproduction

Explanation and Analysis: There really are a lot of characteristics overlooked when talking about Elephants as a whole species.

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

Dr. Kim Vonnahme has been a very important addition to the Animal Science Department at NDSU for the past eleven years. She has brought her tremendous knowledge of the reproductive tracts in animals to research and hands on projects for the students here at NDSU. Dr. Vonnahme received her Bachelor of Science Degree in Animal Science at Iowa State University in 2006. She continued to further her educational background by attending Oklahoma State University to obtain her Master’s Degree in Animal Science in 1998. Afterwards, she attended University of Wyoming to receive her PhD in Reproductive Physiology (Kim Vonnahme, 2014; Research Profile-Kim, 2014).

The process is often confused with artificial insemination. The latter involves a trained technician using a syringe to inject sperm into a viable egg. Both procedures are often used for couples that experience fertility issues.

For about twenty eight years now the Asian elephant has been struggling for existence. They have been classified as endangered species by The International Union for Conservation of Nature (IUCN). Twenty eight years is quite a large amount of time for an animal to be classified as endangered so The Zoological Society of London decided to look into this issue. Asian elephants have been transferred to captivity for quite some time in the North American region. The Elephas maximus have been captured from these countries in southern Asia and brought over to North America and have experienced many complications that can hinder the genetic diversity of the evolution of the species. Captive populations of the Elephas maximus species may be essential for genetic preservation and aid in decreasing the deterioration of the authentic population (Brenneman et al. 2011).

If a cow, displaying the ‘double muscled’ characteristic was produced, this enables the breeder to inbreed this cow, with the original homozygous recessive bull to create a purely ‘Belgian Blue’ breed. Other technology has increased the concentration of these desirable traits. To ensure farmers are not jeopardising their stock population, artificial insemination is a new form of genetic engineering technology. Artificial insemination/embryo breeding is a process that involves inserting the semen sample of a bull and inserting it into the heifers uterus. Or taking eggs from a heifer and semen from a bull and inserting into the uterus of another heifer. This process can increase the concentration of selective breeding as the cows with less desirable traits are enable to breed as farmers insert reproductive cells of the biggest and best cattle into to the average cows and therefore increase production of offspring. Embryo breeding has become reasonably affordable and therefore farmers can increase productivity to meet increased meat

Although we assume that fertility drugs would be the most commonly used fertility method, the artificial insemination method is to be found the most common. Artificial insemination is when “washed” sperm is inserted directly into the uterus through a thin and flexible catheter during IUI. When artificial insemination is the chosen method, a doctor may recommend the use of fertility drugs. Fertility drugs are most commonly used to induce ovulation increasing egg production and making embryo implantation more receptive. Another possible method is IVF, which is in vitro fertilization. IVF is a cycle in which eggs are extracted and fertilized with sperm in a lab. Once the embryos develop, one or two are implanted into the uterus and the rest are stored. An option like IVF, is ZIFT. ZIFT is zygote intrafallopian transfer. Instead of the embryo being inserted into the uterus, it is inserted into the fallopian

This experiment will be conducted using fifty Angus calves born within 2 weeks of the same date. To insure the calves are born within this time frame the calves will be collected from cows that have been inseminated from the same bull at the same time and tested positive for pregnancy. These calves will be castrated with the Short scrotum method with the use of a rubber ring. This method involves restraining the calf, preferably in a squeeze chute, and taking a tool to expand the tight rubber band and placing both testicles through the band. While doing this the band must be firmly against the naval at the base of the scrotum before releasing the rubber band. Twenty-five of the calves will be castrated at a week old. The other twenty-five will be castrated at the age of

An advanced reproductive instrument is used this is called In-Vitro Fertilization or IVF. This device

Artificial insemination (AI) is when sperm is placed into a female's uterus (intrauterine) or cervix

The population consists of two main species of Elephant, the Asian and the African. The Asian elephant is divided into three subspecies: the Indian, Sumatran, and the Sri Lankan (“Asian Elephant”). African elephants are split into

Scientists at the Genetics and In Vitro Fertilization Institute in Virginia have already adapted a sperm sorting system that was originally developed for breeding farm animals. This system offers patients the option of predetermining

When an male African elephant reaches puberty he will leave his natal family because he needs to join a

Elephants are an endangered species and their fatality rate is rapidly inclining. According to Graham Boynton, there happens to be fewer African elephants being

Since the time of insemination is extremely important, your partner should be prepared to have to collect semen by masturbation in the clinic. The procedure may also cause discomfort to the woman if there are difficulties in catheter insertion. Furthermore, when possible insemination cramping like menstrual.
