If you are to "hand" breed a mare and a stallion it is much safer and the situation is controlled versus if the mare and stallion are alone together in a pasture either one of them could get hurt very seriously either from biting or kicking.
The advantage of animal breeding is that animals that are close to extinction can be repopulated. The disadvantage of animal breeding is over population of common animal species.
The advantages of using a hand saw over a table saw tend to be more of a personal preference. Many believe the table saws to have more advantages but the one advantage of a hand saw is the accuracy of the cut.
Switching over, rotating, moving livestock to a new pasture, etc.
Yes. If you are hand-broadcasting seed over a pasture or in spots where a cow can eat it, she will defecate it out. This seed will grow from this manure and thus repopulate the current stand in the pasture.
From my research I have found that a hand truck and a platform cart are the exact same thing and there are no advantages of one http://www.handtrucksrus.com/newplatform.aspx
In the United States, market steers and heifers spend their time eating and growing until they are taken to market. Breeding cows are typically left on pasture all summer with their calves and bred via a bull in the herd in the early summer months. The calves are weaned and sent to a grower lot in the fall and the cows are turned back out on winter pasture. They calve in the spring, and the cycle starts over until they are removed from the breeding herd.
None really, besides maybe being wanted more for breeding. if anything, it's worse because they stand out more.
Artificial pasture is more or less equivalent to the term "tame pasture" in North America. It is a pasture that contains grasses that are tame, non-native or "soft" over grasses that are native, wild or "hard." The latter is called "natural pasture." Artificial pastures contain grasses that are more vigorous, competitive and tend to have a much higher forage biomass over a growing period than native grasses do, making them ideal for grazing in a controlled system over a nomadic pastoral system typical of natural pastures. Native versus artificial pastures are terms that are used in eastern Europe, parts of Asia and Africa. Please see the related links below for more information.
Yes there are some advantages, but also some disadvantages, choose the one best suited for your personal needs.
Advantage of the cotton gin was to speed up and have a more efficient production of cotton.
No if you put a ligh layer over the pasture then no, this is actually extremly benificial to the grass (for horse manure is great fertilizer).
