Advantages and disadvantages of cloning and transplanting cattle embryo

OccupyTheory on 30 September, at There are benefits as well as potential drawbacks in cloning animals. Still, the industry is continuously developing and the future creations are quite promising. The Advantages The following are the advantages of cloning animals:

Plant seeds 4 to 6 inches deep. In September she had noticed that 7 of the 12 seeds she planted spring from fall seed harvest were now 4 to 6 inch tall seedlings. All were planted on this south-facing forested slope along a creek south of Dayton OH, deciduous canopy.

Each seed had been planted 6 inches deep and was surrounded by a mesh of chickenwire also buried 6 inches and staked. Confirming that Torreya seeds easily sprout at that depth is important news for future free-plantings seeking rodent protection via depth.

Do seeds planted 5 to 6 inches deep do almost as well if no soil caging is used? If so, then we can fully recommend the easiest form of free-planting that is, no cage and no rocks so long as seeds are put at great depth? I began planting some seeds directly into forested landscapes to test natural ways to deter squirrels from digging up the seeds.

Below are photos of 3 methods I used: While all 3 methods appear to entirely deter squirrels, results vary for voles. Logs and probably thatch attract voles looking for shelter; who easily tunnel underneath.

While voles can also tunnel under rocks, if the rock is not too big and especially if it is out in the open distant from logs and branchesthen a seed has a good chance of not being discovered by voles.

Therefore, never plant seeds under or near logs! So if you only have 20 seeds, do not experiment with free-planting. And if you do free-plant, record your actions and report back to us on what you have learned.

We are still very much in an experimental phase. As well, if you are tempted to pick up the rock on occasion to see if germination is happening, that is probably okay.

But never prop up the rock, not even slightly, if you see germination. Gently put it back down exactly as you found it. In spring of I noticed that 3 rocks had short white beginnings of stems visible directly beneath the rock. I always placed the rock initially so that the seed was precisely in the center.

For 2 of those, I made a bad choice: I propped up the rock about half an inch on one side, using sticks or small rocks. Six months later, only the unpropped rock had a stem emerging out into the air and the other two had no evidence of any seed left.

In the photos below of 5 emergent seedlings, you will see that the seedling always emerges from the upslope edge of the rock. Because I am unwilling to lift up the rock once I see a seedling emerging into the air, I do not know whether Torreya survives if ants or large hibernating beetles choose to live under the rock.

Some rocks had insects under them; some did not when I peeked under them Spring I detect no pattern as to whether insects will be there or not.

But it would be useful if someone discovered that Torreya actually can occupy the same rock as active insects. Daein Ballard New Hampshire reports that he found ants under all the rocks with ungerminated seeds free-planted.

Basically, from now on I recommend putting seeds 4 to 6 inches deep as the ideal method of free-planting. It would be very useful to learn whether squirrels are unable to smell a deeply buried torreya seed.

And given the size of seed, Torreya is likely capable of sending a stem outward from a rock or upward from a deep hole for quite a distance.

This would be an important experiment to help us learn the safest easy method for free-planting. Spring I experimented with 6 pairs of seeds "free-planted". I will report results.

Thus far, 5 seedlings have emerged from rocks, and all emerge on the upslope side of its rock. These three photos show different views of the same seedling.

It was one of 2 that had their tops nipped off by some animal. Torreyas outdoors tend to have two flushes of vegetative growth each year: Torreya readily produces basal sprouts as back-up in case the main stem has trouble, so this seedling will probably survive, via a basal sprout yet to emerge.

This seedling, with just one-year's growth above ground, is the tallest and lushest of the five.Chapter 11 Brief overview of emerging technologies. It took more than 80 years from the demonstration that embryo transfer was possible in laboratory animals, until it started to be used commercially.

Topic Homeostasis The Importance of homeostasis. You should be able to explain that homeostasis is the regulation of the internal conditions of a cell or organism to maintain optimum conditions for function in response to internal and external changes.

The economic advantages of cloning and transplanting cattle embryos is the you can mass produce cows for succulent beef also you can provide wonderful creamy milk which will g ive your country and family a more rich and wealthy life. The disadvantages of cloning is that the beef could become toxic if it is cloned incorrectly.

The embryo is usually taken from the donor mare by uterine lavage at around 6 to 8 days after ovulation, with day 7 being the optimal retrieval time according to most veterinarians.

Advantages and Disadvantages of Embryo Transfer. Embryo transfer has a number of advantages for the donor mare, the recipient mare, and the horse owner.

Cloning and transplanting cattle embryos Embryo cloning involves giving top-quality cow fertility hormones so that it produces a lot of eggs. since the cows are of a much higher quality they can sell them at a premium Economic Disadvantages – The beef from cloned cows can become toxic if the cow is not cloned properly.

so poorer people can. Advantages. Embryo transplant is skilled and expensive work, but it is worth it because using normal reproduction, a cow might produce calves.
