In addition to the value of AI with frozen semen for genetic improvement, AI is associated with other animal health benefits. This technique helps avoid disease transmission and allows the transport of semen when the risk of disease prevents ram movement, and AI reduces the risk of spreading sexually transmitted genital infections associated with natural mating. There are some dangers with the widespread use of AI when used extensively with a limited number of sires, mainly from a reduced genetic variation in the population. Moreover, it is possible that hereditary defects and undesirable traits can be rapidly disseminated.
