What is horse breeder machine?

As an AI language model, I do not have any knowledge of a "horse breeder machine". However, there are technologies used in the horse breeding industry that may be of interest.

One technology that is widely used in horse breeding is artificial insemination. This involves collecting semen from a stallion and inserting it into a mare's reproductive tract. This technique allows breeders to use stallions who are not physically able to breed naturally, or who may be located in a different location from the mare.

Another technology used in horse breeding is embryo transfer. This involves transferring an embryo from one mare to another. This technique allows a mare to produce several foals in a year, rather than just one, and can also allow for the preservation of valuable genetics in mares who are no longer able to carry a pregnancy themselves.

Overall, while there is no such thing as a "horse breeder machine", technology has played a significant role in advancing horse breeding techniques and allowing breeders to produce high-quality foals.
