The lowest stud fees to breed to a grade horse or an animal of low-quality pedigree may only be $100–$200, but there are trade-offs: the horse will probably be unproven, and likely to produce lower-quality offspring than a horse with a stud fee that is in the typical range for quality breeding stock.

The mule is a domestic equine hybrid between a donkey and a horse.It is the offspring of a male donkey (a jack) and a female horse (a mare). [1] [2] The horse and the donkey are different species, with different numbers of chromosomes; of the two possible first-generation hybrids between them, the mule is easier to obtain and more common than the hinny, which is the offspring of a male horse ...
Many animal species have specific mating (or breeding) periods e.g. (seasonal breeding) so that offspring are born or hatch at an optimal time. In marine species with limited mobility and external fertilisation like corals , sea urchins and clams , the timing of the common spawning is the only externally visible form of sexual behaviour.
If a horse is not to be used for breeding, it can be gelded prior to reaching sexual maturity. A horse gelded young may grow taller [ 21 ] and behave better if this is done. [ 22 ] Older stallions that are sterile or otherwise no longer used for breeding may also be gelded and will exhibit calmer behavior, even if previously used for breeding.
[4] [5] This leads males to evolve aggressive mating behaviors which can help them acquire mates. [5] Sexual coercion has been observed in many clades, including mammals, birds, insects, and fish. [6] While sexual coercion does help increase male fitness, it is very often costly to females. [5]
