A stallion is a breeding stallion. Also known as a stallion.
In livestock such as cattle, pigs, and sheep, it is permitted to collect and cryopreserve the sperm of excellent sire, but in horse production represented by racehorses, artificial insemination and the use of frozen sperm are generally used. Refuses artificial insemination by. Frozen sperm are easy to store, transport, and sell, but in horse production, live stallion must always be bred directly to live breeding mare (broodmare).
Therefore, even if there is a good stallion, it cannot be bred in an area that is immovable for breedmare, and eventually it will die at the end of its life, so the production world always creates and discovers a new good stallion. There is a need. Also, in the case of racehorses, it takes about 4 to 5 years from the time of mating until the child is born and reaches the race age and a certain grade can be judged, so it becomes a new stallion. There is a time lag before it becomes clear whether something is good or not.
Due to these circumstances, the stallion market is more fluid than other livestock markets.
This section mainly describes racing stallion. There are also differences between riding and meat stallion.
Until you become a stallion
In Japan, racehorses that have retired from the race in Japan, those that have not participated in the race but are expected to become stallion due to their pedigree, and those that are imported from overseas will become new stallion. Since pedigree management is required for horses used for breeding, there is no such thing as capturing wild horses for breeding stallion (also breeding mares). Of course, gelding that has lost reproductive function is not eligible to become a stallion because it must have reproductive function (artificial insemination is not allowed). Even if it has a reproductive function and becomes a stallion, it may be found that it is not fertile for some reason.
The institutions that register differ depending on the breed of horse, but in the case of light horses including Thoroughbreds, the Japan Bloodhorse Breeders Registration Association has registered the pedigree, and those that will be new Thoroughbred stallion are registered by the Japan Bloodhorse Breeders Registration Association. Need to receive.
Owning a stallion
The owner of the stallion collects a seeding fee from the owner of the breedmare and mates it. The more proven and popular stallion, the higher the stud fee, and in the case of the highest level stallion in Japan, not all of them are announced as described below, but they are announced. Some of them cost more than 10 million yen for seeding. On the other hand, in the case of unpopular broodmases, they may try to collect broodmases by keeping the seeding fee low and, in some cases, by offering free or a certain amount of money to the owner of the broodmare that has been brooded. In this case, ownership of the stallion is often done as a hobby rather than as a business. Also, in the past, the seeding fee was a consideration for the mating itself, and it was customary that the mare was not refunded even if it did not become pregnant, but from the 1980s, the following new seeding fee payment formats have appeared.
Conception conditions: A form in which the seeding fee is paid only when pregnancy is found.
Live Fall: A form in which part or all of the seeding fee is refunded in the case of stillbirth or miscarriage without giving birth even if pregnant.
Free return: A format that allows free mating only for the same mare the following year (with some exceptions) if the mare cannot be produced for some reason. Produced by seeding the following year with the right only for the next year
