Cattle Artificial Insemination Research Paper

Artificial insemination is a method of reproduction that allows beef producers to use bulls that have superior genetics at an affordable price. Many producers of purebred and commercial beef cattle profitably use artificial insemination in their cow herds and utilize artificial insemination to control traits such as calving ease, milk production, and feed efficiency. Take my family for example; every year we sync our show heifers’ estrus cycles together and artificially inseminate them. Artificial insemination allows us to pick sound, purebred bulls with low birth weights, something that is ideal for our show heifers. A successful artificial insemination program requires attention to detail, and timing is crucial. Both a sound health

Bringing desirable material traits into a commercial herd through maternal herd sires is Brett’s goal.

This is possible during genomic selection and embryo transfer because we can scan and evaluate the DNA of both the individuals to be bred together and also the embryos created so that we can look for deformities and undesirable traits. These individuals or embryos will then be eliminated from the reproduction process. This is advantageous because even if the dairy cow offspring produced has all of the desirable traits of being a dairy cow (e.g. large udder, high quality milk) but also has a disease, they will die before being able to be biologically successful and pass on their desirable genes. Therefore, this is a positive implication for the health of the

No differences were seen in performance of steers across all treatments. Final BW shows that in each treatment the steers gained on average 15 kg over the 28-day process. As noted on Table 3, DMI was greater for steers fed once a day than for steers fed once a week, and in the control group. However, the results show that ADG for the control was greater overall. Therefore performance was improved no matter what type of supplemental intake. Results of cost take into account cost of feed, labor, and a pasture acre fee. Therefore, it is cheaper overall to supplement cattle on pasture rather than feeding weekly or once a day. Several possibilities as to why performance was not affected may include environmental factors (heat), forage quality, and rate that steers were

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.

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

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

Once the stallion is done on the phantom I take the AV back out of the phantom and take it into our lab. While my grandmother puts the horse away. I take the semen into the lab where I make sure it is good enough to breed a mare with. The first thing I do is put a sample under the micro scope. I look to make sure they are in good shape because there is no reason in trying to breed with dead sperm. Once I see that there is enough moving I put it into a machine that counts the amount of sperm. The number has to be above 150 to even be worth using, and 300 is the best we have ever gotten. By this time my grandmother comes in to help me do the math calculations. We mix the semen with extender, which is what the semen feeds off of. After this I go get the mare and put her in the stocks to keep her from kicking anyone. My job was to clean the mare out so no manure was in the way when my grandmother goes in with a probe to look around. Then my grandmother looks on each ovary to see if the mare is in heat. When the mare is in heat, my grandmother leaves the rest to me, while she moves on to the next horse in

The sperm concentration of sons born to mothers with low beef consumption was 24.3 higher than mother with high beef consumption. (Organic Consumer Association) Eighteen percent the sons born to mothers in high beef consuming group had a sperm concentration below the World Health Organization threshold. (Organic Consumer Association) However, even with all the scientists concerns and studies, the United States, backed by the world trade organization still allow the use of growth promoting hormones in cattle.

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

This system is an excellent choice as it produces maximum heterosis in both the calf and cow (51). As such, calves obtain the additional growth benefits of hybrid vigor while heterosis in the cows improves their maternal ability. The terminal cross system is one of the simplest systems to implement and achieves the highest use of heterosis and breed complementarities (17,44). All calves marketed will have the same breed composition. A 24% increase in pounds of calf weaned per cow exposed is expected from this system when compared to the average of the parent breeds.

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,

A bull being used for artificial insemination can breed up to 500,000 cows in their lifetime, which is usually only 5 to 10 years. After their death, a bull’s semen that is kept in the correct way, can still be used to breed generations down the line. The time for keeping semen frozen is projected at 40-45 years old. A bull that is known greatly in the show cattle industry for being deceased and still able to buy semen from them is the bull, Man Among Boys. With artificial insemination, a person can breed for the qualities they want or need, unlike natural breeding which they would receive only the qualities from the same bull that is located at their farm. Also, an advantage of artificial insemination is the availability. Anyone can find semen sales anywhere from a local cattle farm or online. And finally, fewer sires on a person’s farm is needed because they would receive a stick of semen instead of an entire

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

This will tremendously benefit farmers who raise livestock, and cloning of the superior animals will also make the food supply healthier and larger in this growing world.
